COULD A SHINGLES VACCINE HELP PREVENT DEMENTIA? A NEW STUDY SAYS YES—ESPECIALLY FOR WOMEN

by Anshika Mishra April 8, 2025

written by Anshika Mishra

Imagine if protecting yourself from a painful skin condition could also help lower your chances of developing dementia. That’s exactly what a new study from Stanford University School of Medicine has found—revealing that the shingles vaccine may offer unexpected benefits far beyond what it was originally designed for.

Published in the prestigious journal Nature, the study suggests that getting vaccinated against shingles could reduce the risk of dementia by up to 20%. Even more interesting? Women appear to benefit more from this protective effect than men.

The Study That Sparked a Big Discovery

The research analyzed the medical records of over 280,000 older adults in Wales, aged between 71 and 88, who were eligible for the shingles vaccine starting in 2013. To study the impact as accurately as possible, scientists used a “natural experiment” approach. Instead of relying on self-selection or lifestyle variables, they compared two similar groups: one that barely qualified for the vaccine and another that just missed the eligibility cutoff.

Specifically, they focused on people who turned 80 just before September 1, 2013—right when the shingles vaccination program began in Wales. This allowed researchers to see how the vaccine impacted long-term health outcomes while minimizing bias from individual lifestyle choices.

What They Found: Dementia Risk Dropped by 20%

Over a follow-up period of seven years, the researchers made a fascinating discovery. People who received the shingles vaccine were:

37% less likely to get shingles, and
20% less likely to be diagnosed with dementia.

To put it in perspective, the vaccine reduced the likelihood of developing dementia by 3.5 percentage points—a significant drop when applied to large populations.

By the year 2020, about one in eight adults aged 86 or 87 had been diagnosed with dementia. But among those who had received the shingles vaccine, that rate was notably lower.

Why Might the Shingles Vaccine Help the Brain?

The connection between a shingles vaccine and reduced dementia risk may seem surprising at first. But there’s growing evidence that certain viruses can damage the nervous system and potentially increase the risk of neurodegenerative conditions like dementia.

Shingles, medically known as herpes zoster, is caused by the varicella-zoster virus—the same one responsible for chickenpox. After someone recovers from chickenpox, the virus can remain dormant in the body and reactivate years later as shingles, often causing painful rashes and nerve damage.

Researchers suspect that this virus, when reactivated, may cause inflammation or other harmful effects in the brain. By preventing the virus from reawakening, the shingles vaccine may also help protect brain health.

Women Showed Stronger Protection—Here’s Why

One of the most striking aspects of the study was the finding that women appeared to benefit more from the vaccine’s protective effect than men. While the reasons aren’t yet fully understood, it’s likely related to biological differences in how men and women respond to vaccines.

Women are known to have stronger immune responses, often producing more antibodies after vaccination. Interestingly, shingles is also more common in women, which could mean the vaccine is preventing a more prevalent issue in that group—leading to a more noticeable benefit.

A Possible Breakthrough in Dementia Prevention

Dementia is a growing global health challenge, affecting millions of people around the world and placing immense strain on families, caregivers, and healthcare systems. Despite years of research, effective ways to prevent the disease remain limited.

This new study could open the door to an affordable, already-available preventive measure. If future research confirms the findings, shingles vaccination could potentially be added to public health strategies aimed at reducing dementia risk.

While the study stops short of recommending the vaccine solely as a tool for dementia prevention, it does strongly support the idea that vaccines—especially those targeting viruses with neurological impacts—could play a bigger role in brain health than previously thought.

What This Means for You

If you’re over 70—or approaching that age—it may be time to talk to your doctor about the shingles vaccine. While its primary goal is to protect you from a painful and often debilitating viral infection, it could also offer the added bonus of protecting your brain.

For younger readers, this research highlights the fascinating and still-evolving relationship between infectious diseases and chronic conditions like dementia. It’s a reminder that sometimes, preventing one illness can have unexpected benefits in other areas of health.

And for everyone, it shows the power of vaccination—not just in fighting infections, but possibly in protecting long-term cognitive function as well.

In Summary:

The shingles vaccine may reduce dementia risk by 20%, especially in women.
Researchers studied over 280,000 older adults in Wales over seven years.
Vaccinated individuals were also 37% less likely to develop shingles.
The protective effect might be due to reduced viral reactivation and inflammation in the brain.
Women may benefit more due to stronger immune responses.
The findings could influence future strategies for dementia prevention.

As science continues to explore the connection between infections and brain health, this study offers a promising new avenue—one that could help millions age with greater clarity and quality of life.

SLEEPING WITH THE LIGHTS ON? IT COULD BE SECRETLY RAISING YOUR RISK OF DIABETES AND HEART DISEASE

by Anshika Mishra April 8, 2025

written by Anshika Mishra

Ever fallen asleep with the lights on or scrolled through your phone right before bed? You’re not alone. But did you know that something as simple as room lighting at night could be silently sabotaging your health?

We’ve all heard the usual advice—“Turn off the lights before bed,” “Avoid screens at night”—but there’s more science behind it than just helping you fall asleep faster. Recent research shows that sleeping with lights on can mess with your blood sugar levels and your heart health—even after just one night.

What the Science Says

A study published in 2022 in the Proceedings of the National Academy of Sciences sheds light (pun intended) on this issue. The researchers wanted to understand how light exposure during sleep affects glucose (blood sugar) regulation. In other words, can a simple thing like having the bedroom light on make it harder for your body to handle sugar the next morning?

Turns out, the answer is yes.

The study involved 20 healthy young adults divided into two groups. One group slept in dim light for two nights. The other group spent the first night in dim light, and the second in brighter room lighting—equivalent to a softly lit room, not a spotlight.

The next morning, the researchers measured their blood sugar and other vital signs. Those who slept under brighter lighting showed signs of increased insulin resistance, which means their bodies weren’t using insulin as effectively to manage sugar in the blood. This is a red flag, because insulin resistance is linked to prediabetes, type 2 diabetes, and other metabolic issues.

Why Is Light at Night a Problem?

So how exactly does a light bulb disrupt your metabolism?

It comes down to your nervous system, sleep quality, and melatonin—the hormone that helps regulate your sleep-wake cycle.

Here’s what the researchers observed in people who slept with the lights on:

Poorer sleep quality: Less time in deep and REM (rapid eye movement) sleep.
Increased heart rate: A sign that the body wasn’t fully relaxed.
Higher nervous system activity: Especially the sympathetic nervous system (the “fight or flight” system), which should be low during restful sleep.
Lower melatonin levels: Light suppresses melatonin, which not only controls sleep but is also connected to insulin sensitivity and metabolism.

In simple terms, sleeping with the lights on keeps your body in a state of alertness—even while you’re asleep. And that internal stress can lead to poor blood sugar control.

Why It Matters

The takeaway from this research is important: even one night of light exposure while sleeping can negatively affect your metabolic health. Over time, if this becomes a regular habit, it could contribute to long-term issues like:

Type 2 diabetes
Heart disease
Poor sleep quality
Weight gain

And you don’t need to be glued to your phone for this to happen. A bedside lamp, hallway light, or TV glow is enough to disrupt your natural sleep and metabolic processes.

How to Improve Your Sleep—and Your Health

Luckily, there are simple steps you can take to improve your sleep hygiene and protect your long-term health. Here’s what experts suggest:

1. Stick to a Sleep Schedule

Try to go to bed and wake up at the same time every day—even on weekends. This helps regulate your internal body clock, making it easier to fall asleep and wake up naturally.

2. Create a Relaxing Bedtime Routine

Avoid screens (phones, tablets, TVs) at least an hour before bed. The blue light from these devices can block melatonin production. Instead, unwind with reading, journaling, or meditation.

3. Make Your Room Sleep-Friendly

Keep it dark: Use blackout curtains or a sleep mask if needed.
Stay cool: A cooler room temperature (around 65°F or 18°C) is ideal for most people.
Minimize noise: Use earplugs or white noise if outside sounds keep you up.
Ditch night lights: If you need one, use a red or amber night light, as these colors are less disruptive to melatonin.

4. Be Smart About Light

Try to limit artificial lighting in the evening. Dim the lights an hour before bed to help signal to your brain that it’s time to wind down.

If you use your phone or computer at night, turn on “night mode” or use blue light blocking glasses.

5. Invest in Comfort

A good mattress and pillow can significantly improve your sleep posture and depth of sleep. Your bed should support your body without causing aches or stiffness.

The Bottom Line

This study is a powerful reminder that even small changes in our environment—like lighting—can have a big impact on our health. The light that seems harmless at night might be working against your body while you sleep, disrupting your hormones, your rest, and even your blood sugar levels.

So the next time you think about falling asleep with the TV on or skipping your wind-down routine, think again. Dim the lights, put away your phone, and give your body the restful, healing sleep it needs.

After all, good sleep isn’t just about feeling rested—it’s about staying healthy, now and in the long run.

SCIENTISTS DEVELOP STARFISH-INSPIRED SMART WEARABLE FOR REAL-TIME HEART MONITORING

by Anshika Mishra April 8, 2025

written by Anshika Mishra

In a breakthrough that blends biology with cutting-edge tech, scientists have developed a starfish-inspired wearable device capable of tracking the heart’s activity in real-time—even during high-intensity movement. This lightweight, flexible innovation could redefine how doctors monitor cardiovascular health, making it easier to detect serious conditions like heart attacks and irregular rhythms well before they become life-threatening.

The design, which mimics the five-armed symmetry of a starfish, allows for a unique configuration that improves the accuracy and reliability of heart monitoring, especially during physical activity. The device was developed through a global collaboration among researchers from the United States, China, and Saudi Arabia, with findings recently published in the prestigious journal Science Advances.

Why Starfish? The Science Behind the Shape

One of the key challenges in wearable heart monitoring has been movement interference. Devices often lose accuracy when the person wearing them moves—something that’s inevitable in real life. Traditional biosensors are typically built on a single, flat surface, which limits their ability to stay accurate when subjected to the motion of daily activities.

That’s where the starfish comes in.

Lead researcher Dr. Sicheng Chen, a postdoctoral fellow at the University of Missouri (Mizzou), explained that their team turned to nature for a smarter solution. “Inspired by the pentaradial (five-armed) shape of starfish, we reimagined the wearable device’s structure,” he said. “This design helps minimize mechanical interference from body movement and ensures more accurate readings.”

Instead of cramming all sensors and components onto a single flat sheet, this new device spreads them out across five flexible “arms.” This distributes movement and allows the device to remain more stable on the skin, capturing cleaner biosignals even when the wearer is walking, running, or exercising.

Three Types of Heart Signals—Captured Together

The wearable is capable of recording three different types of heart data at once:

Electrocardiogram (ECG): Measures the heart’s electrical activity.
Seismocardiogram (SCG): Records chest vibrations caused by the heartbeat.
Gyrocardiogram (GCG): Tracks movement of the chest wall during heartbeats.

By combining all three, the device provides a much richer and more detailed picture of heart function than standard monitors. More importantly, it does this in real time.

Powered by AI and Connected via Bluetooth

To make sense of all this data, the device uses powerful artificial intelligence algorithms. These algorithms are trained to distinguish real heart signals from noise caused by movement or external factors—ensuring reliable results even in less-than-ideal conditions.

Once the data is collected, it’s instantly transmitted via Bluetooth to a smartphone app or directly to a healthcare provider. This allows clinicians to keep an eye on their patients remotely and receive alerts if something goes wrong—like early signs of a heart attack, atrial fibrillation (AFib), or heart failure.

In clinical tests, the system was able to identify these conditions with over 91% accuracy, which is a promising sign for early intervention and potentially life-saving monitoring.

Built for Comfort and Convenience

Beyond the science, the engineers behind this project paid close attention to real-world usability. According to the research team, the device is:

Lightweight
Waterproof
Supports wireless charging
Runs on edge computing (meaning it can process data locally instead of relying on cloud services)

These features make it suitable for daily wear, even in active environments. From athletes to elderly patients, the goal is to offer round-the-clock health tracking without requiring hospital visits or bulky equipment.

Importantly, the design is also optimized for mass production, which could help bring costs down and make it more widely accessible in the near future.

The Comfort Factor

Despite its many advantages, the device isn’t perfect yet. One of the main issues the researchers are still addressing is skin irritation. Prolonged use of current adhesive gels can cause discomfort or allergic reactions—especially for people with sensitive skin.

Dr. Zheng Yan, a senior researcher and associate professor of chemical and biomedical engineering at Mizzou, noted this ongoing challenge: “A big issue with wearable devices is that they can become irritating when worn for long periods. We are actively working to improve this by developing more breathable, skin-friendly adhesives.”

The team is experimenting with new materials that are both secure and gentle on the skin, allowing for long-term wear without discomfort. The ultimate aim is to create a monitor that people can wear day and night without even noticing it.

What This Means for the Future of Heart Health

Cardiovascular diseases remain the leading cause of death globally. Many of these conditions can be better managed—or even prevented—if detected early. Traditional monitoring methods often require bulky equipment, scheduled appointments, and short-term testing windows that may miss warning signs.

This new wearable changes that. It brings the hospital-level monitoring straight to your wrist (or chest), providing clinicians with a constant stream of real-time data.

The implications are far-reaching:

Preventive healthcare: Early detection of heart abnormalities can lead to timely treatment and better outcomes.
Remote care: Doctors can monitor patients from afar, reducing the need for frequent hospital visits.
Accessible health tech: A wearable that’s affordable and comfortable could dramatically improve healthcare access in remote or underserved areas.

A Glimpse into the Future

The starfish-inspired wearable is a shining example of how nature can inform smarter, more practical technology. By addressing both technical performance and user comfort, the research team has developed a promising tool in the fight against heart disease.

While some challenges remain—like improving long-term wearability—the foundation is solid. As this device continues to evolve, it could soon become a common feature in the daily lives of those who need close heart monitoring, turning what was once invasive and episodic into something continuous, intelligent, and potentially life-saving.

ONE WOMAN DIES EVERY 2 MINUTES FROM PREGNANCY COMPLICATIONS: UN REPORT

by Anshika Mishra April 8, 2025

written by Anshika Mishra

Imagine this: every two minutes, somewhere in the world, a woman dies while giving birth or during pregnancy. It’s a heartbreaking reality uncovered by a recent United Nations report that highlights how far we still have to go in making childbirth safe for all women, regardless of where they live.

The report, titled Trends in Maternal Mortality, pulls data from 2000 to 2020 and paints a troubling picture. Despite some early progress, maternal deaths have largely stalled or even worsened in recent years, with nearly 287,000 women dying in 2020 alone due to complications from pregnancy and childbirth. That’s only a small drop from 309,000 in 2016—the year the UN’s Sustainable Development Goals (SDGs) were adopted—indicating slow and uneven improvement.

A Dangerous Journey Instead of a Joyful One

“Pregnancy should be a time of hope and excitement,” said Dr. Tedros Adhanom Ghebreyesus, Director-General of the World Health Organization. “But for millions of women, it remains a risky, even life-threatening experience—especially when quality healthcare is out of reach.”

The study reveals that maternal deaths are increasing or stagnating in nearly every global region. Particularly concerning are the 17% rise in maternal deaths in Europe and North America and a 15% increase in Latin America and the Caribbean between 2016 and 2020.

However, there is a silver lining. Some regions, such as Australia and New Zealand, and Central and Southern Asia, saw notable declines in maternal mortality—by 35% and 16% respectively—proving that with the right policies and healthcare systems, progress is possible.

A Crisis Rooted in Inequality

The vast majority of maternal deaths occur in the world’s poorest and most crisis-affected areas. Sub-Saharan Africa, for example, accounted for about 70% of all maternal deaths in 2020. In countries facing severe humanitarian crises, maternal death rates are more than double the global average—551 deaths per 100,000 live births compared to 223 globally.

Catherine Russell, Executive Director of UNICEF, emphasized how preventable these deaths are. “No woman should have to risk her life to bring a child into the world. We already have the tools and knowledge to prevent most maternal deaths—it’s time we ensure all women have access to them.”

What’s Causing These Deaths?

The main causes of maternal death are well-known—and largely preventable. They include:

Severe bleeding (especially after childbirth)
High blood pressure during pregnancy (pre-eclampsia and eclampsia)
Infections related to childbirth
Unsafe abortions
Complications from pre-existing conditions like HIV/AIDS and malaria

Each of these issues can be treated or prevented with timely, high-quality care. But millions of women never receive that care due to a lack of access, underfunded health systems, and shortages of trained healthcare workers.

Dr. Juan Pablo Uribe of the World Bank called for urgent action. “We need more investment in primary health care and stronger health systems. That’s the only way we’ll save lives and protect women’s health.”

The Missing Links: Healthcare Access and Reproductive Rights

Too many women still go through pregnancy and childbirth without even the most basic medical attention. One-third don’t receive the minimum recommended four antenatal checkups, and many also miss out on essential postnatal care. Around 270 million women globally still lack access to modern family planning tools—preventing them from making informed decisions about when and how to have children.

This lack of control puts women at higher risk, especially those from marginalized communities who already face health inequalities due to factors like income, education, or race.

UNFPA Executive Director Dr. Natalia Kanem said it plainly: “It is unacceptable that over 280,000 women die in a year from causes we can prevent. What’s missing isn’t solutions—it’s the political will. We need urgent investments in family planning and to close the global shortage of 900,000 midwives.”

The COVID-19 Setback

Though the data ends in 2020, there’s reason to believe that the COVID-19 pandemic may have worsened the maternal health crisis. Not only did healthcare systems become overstretched, but pregnant women infected with the virus faced added risks.

Experts urge countries to ensure that women—especially those who are pregnant or planning a pregnancy—have access to COVID-19 vaccines and continuous, high-quality maternal care.

A Call for Collective Action

According to John Wilmoth, Director of the UN’s Population Division, “Reducing maternal deaths is one of the biggest challenges in global health today. But it’s not an impossible one. It just takes sustained commitment, strong systems, and equitable access to care.”

The report’s warning is stark: if the world does not accelerate its efforts, over one million more women could die by 2030 from preventable complications in pregnancy and childbirth.

But there is hope. The solutions exist. What’s needed now is unity, funding, and the determination to ensure that no woman dies giving life.

India’s Obesity Surge Prompts Call for Tax on Junk Food and Sugary Drinks

INDIA’S GROWING CHILDHOOD OBESITY CRISIS: EXPERTS PUSH FOR ‘HEALTH TAX’ ON JUNK FOOD AND SUGARY DRINKS

by Anshika Mishra April 8, 2025

written by Anshika Mishra

In India, childhood obesity is no longer a distant concern—it’s a full-blown health crisis knocking on the nation’s doorstep. With millions of children grappling with excess weight, and diet-related diseases on the rise, a powerful consortium led by the Indian Council of Medical Research-National Institute of Nutrition (ICMR-NIN) is calling for immediate and sweeping reforms. Chief among them: a bold “health tax” on ultra-processed foods that are high in fat, sugar, and salt, along with tighter regulations on products aggressively marketed to children.

This move comes at a critical time. India is witnessing an alarming rise in adolescent obesity, with data showing a massive surge in the number of morbidly overweight children aged 5 to 19 years—from just 0.4 million in 1990 to a staggering 12.5 million by 2022. These figures paint a grim picture of a nation that is rapidly shifting from undernutrition to overnutrition, especially in urban areas where processed snacks and sugary beverages have become staples in children’s diets.

A Call for Action

The ICMR-NIN-led group, comprising nutritionists, doctors, and public health experts, has emphasized that curbing this growing epidemic requires an aggressive, multi-pronged approach. At the core of their recommendations is the introduction of a dedicated health tax aimed at disincentivizing the purchase and consumption of junk food and sugary beverages.

The group is advocating for an additional tax of 20–30% on items like sweets and confectionery products, and a 32% levy on sugar-sweetened beverages. These measures, they argue, will serve as both a deterrent and a revenue generator—helping to fund awareness campaigns and health programs targeted at children and adolescents.

Importantly, the consortium is not just stopping at taxes. They are also urging policymakers to implement stricter marketing restrictions for foods targeting children, better front-of-pack food labelling, and a ban on the sale of unhealthy foods in and around schools and educational institutions—guidelines that already exist under the Food Safety and Standards Authority of India (FSSAI) but are poorly enforced.

Why the Urgency?

The stakes are high. Obesity is a well-documented risk factor for numerous chronic illnesses, including type 2 diabetes, cardiovascular disease, hypertension, and even some forms of cancer. For children, the consequences are even more severe as excess weight gained early in life is harder to shed and often persists into adulthood, paving the way for lifelong health complications.

Globally, childhood overweight and obesity have increased dramatically over the last few decades. In India alone, the prevalence of overweight children has risen from just 4% in 1975 to over 18% in 2016, and the numbers have only gone higher since. This rapid transformation is largely attributed to drastic dietary changes, increased screen time, reduced physical activity, and the omnipresence of cheap, calorie-dense processed foods.

Despite these worrying trends, India currently lacks a clear and targeted health policy to address the junk food menace. The Goods and Services Tax (GST) regime, for instance, does not distinguish between healthy and unhealthy food products. Nutrient-rich items like fruits and vegetables are often taxed at the same rate—or sometimes higher—than items like carbonated drinks or packaged snacks.

The panel is also pushing for a re-evaluation of how sugar alternatives, such as artificial and non-nutritive sweeteners, are taxed. At present, these are levied at similar rates as regular sugar, despite their distinct properties and health implications. Adjusting these taxation structures, the group argues, would better reflect the nutritional value of different products and encourage healthier choices.

The Science Behind Sugar and Fat: Why These Foods Are So Harmful

Experts warn that diets rich in added sugars and unhealthy fats are a major contributor to obesity and a host of other health conditions. But why exactly are sugary and fatty foods so dangerous, especially for children?

1. Empty Calories, No Nutrition

Added sugars—commonly found in sweetened beverages, candies, baked goods, and cereals—are packed with calories but offer little to no nutritional value. Ingredients like high-fructose corn syrup, cane sugar, and agave syrup are energy-dense but lack essential nutrients such as vitamins, minerals, fiber, or protein. These “empty calories” quickly accumulate in the body and contribute to excess weight gain without providing any real nourishment.

2. Blood Sugar Spikes and Insulin Resistance

Frequent consumption of sugary foods leads to rapid spikes in blood glucose levels, causing a condition called hyperglycemia. This state, when sustained over time, impairs cell function and leads to increased inflammation and insulin resistance—two key factors in the development of type 2 diabetes. High-sugar diets are also linked to leptin resistance, which interferes with the brain’s ability to regulate hunger and satiety, thereby promoting overeating.

3. Disrupted Appetite Signals

Fructose, a type of sugar common in processed foods, has been shown to significantly alter hormone levels related to hunger. It increases the hunger-promoting hormone ghrelin while decreasing peptide YY, the hormone that signals fullness. The result? A constant urge to eat, even when the body doesn’t need more energy. This hormonal imbalance is particularly dangerous in growing children who are still developing their lifelong eating habits.

The Path Forward

The consortium’s proposals have stirred debate, but they are far from unprecedented. Countries like Mexico, Chile, and the United Kingdom have already implemented sugar taxes and marketing restrictions on unhealthy foods, with encouraging results. In Mexico, for instance, a tax on sugary drinks led to a 7.6% decline in their consumption within the first two years, especially among lower-income households.

If India is serious about protecting the health of its next generation, it must act swiftly. A comprehensive national policy that includes taxation, education, marketing restrictions, and access to healthier alternatives is not just a recommendation—it’s a necessity.

While there may be resistance from food industry stakeholders and consumers initially, the long-term benefits of such policies far outweigh the costs. In the words of the consortium’s experts, “Improving the food environment for children today is the only way to ensure a healthier, disease-free India tomorrow.”

The Hidden Dangers of Self-Medication in India

by Dr. Shruthi R March 31, 2025

written by Dr. Shruthi R

In India, self-medication is a widespread practice, where many individuals opt to take medicines without consulting a healthcare professional, often for conditions like common colds, sore throats, or even minor aches. While this practice may seem harmless, the hidden dangers of self-medication are numerous and can lead to unintended side effects, long-term health risks, and even serious medical complications.

Experts have long expressed concerns about the rise of self-medication in India, a country where access to over-the-counter medications is easy, and information is often found through unreliable sources such as the internet. The common misconception that one can treat mild symptoms on their own without medical consultation can be dangerous. The practice is based on self-diagnosis, often resulting in people taking the wrong medications, wrong dosages, or treatments for conditions that might not be what they assume. This can have far-reaching consequences for both individual health and public health in general.

A prime example of the dangers of self-medication is the misuse of antibiotics. Many individuals take antibiotics for viral illnesses, mistakenly thinking they will speed up recovery. However, antibiotics are only effective against bacterial infections and have no effect on viral conditions. Overuse or misuse of antibiotics contributes to antibiotic resistance, which is one of the most serious threats to global health. According to health professionals, self-medication can lead to drug resistance, rendering antibiotics ineffective when they are genuinely needed in future infections.

Additionally, commonly used over-the-counter medicines such as paracetamol, decongestants, and painkillers can cause severe side effects when taken inappropriately. For instance, while paracetamol is widely considered a safe and commonly used medication, excessive consumption without medical supervision can lead to liver toxicity, resulting in severe damage, even liver failure in extreme cases. Overuse of decongestants can result in atrophic rhinitis, which involves the thinning and damage to the inner lining of the nose, resulting in chronic nasal issues.

One of the main reasons for self-medication in India is the perceived ease and cost-effectiveness of obtaining medicines. Many individuals seek to avoid doctor consultations due to financial concerns or because of the long waiting times at hospitals. For some, the costs associated with doctor visits or the perceived inefficiency of the healthcare system deter them from seeking professional medical advice. Furthermore, traditional remedies and advice from family members often replace modern medical practices, resulting in self-diagnosis based on cultural beliefs or misinformation.

The rise of online medical advice and social media platforms has also fueled the self-medication epidemic. In many instances, individuals turn to influencers and non-expert sources for health advice, leading to poor treatment decisions. This is particularly dangerous when it comes to mental health conditions, as individuals might take medications based on advice from social media without realizing the risks involved. Dr. Sneha Sharma, a psychiatrist, explained that many people self-diagnose mental health disorders such as depression or ADHD, using online sources and then seek medication without consulting a mental health professional, potentially exacerbating their condition.

Another contributing factor to this growing issue is the lack of education around the dangers of self-medication. Studies have found that a lack of awareness about the consequences of overusing medications or failing to take them as prescribed can lead to adverse drug reactions. In many cases, individuals are unaware that taking medications without proper guidance can lead to long-term health problems such as kidney damage, gastrointestinal issues, and even drug dependency.

One of the most alarming findings from various studies on self-medication is its prevalence among older adults in India. A cross-sectional study involving older adults from six major Indian cities revealed that a significant percentage of them practiced polypharmacy — taking five or more medications simultaneously. In addition to this, many participants were taking fixed-dose combinations (FDCs) without fully understanding the risks involved. Polypharmacy, especially among older adults, increases the risk of drug interactions, leading to potentially life-threatening side effects.

A major issue with self-medication is the tendency to self-prescribe medications for chronic conditions such as hypertension, diabetes, and pain management. Patients may assume that over-the-counter drugs will suffice for their health issues, overlooking the necessity of medical advice to manage such conditions effectively. For example, taking blood pressure medications based on a one-time elevated reading without confirming the diagnosis or understanding the underlying cause, such as anxiety or stress, can lead to severe complications.

The Growing Risk of Antibiotic Resistance

One of the most significant concerns with self-medication is the overuse of antibiotics. In India, antibiotics are often taken without prescriptions for a variety of ailments. The misuse of antibiotics not only exacerbates the spread of antibiotic-resistant bacteria but also makes it difficult to treat common infections. Dr. Sahil Kapoor, a family medicine consultant, highlighted the issue of antibiotic misuse, explaining that many patients misuse antibiotics for viral infections like the common cold, which antibiotics cannot treat.

When people use antibiotics improperly or stop taking them before completing the prescribed course, bacteria may survive, leading to the development of resistance. As a result, infections that were once easily treatable with antibiotics may become more difficult or impossible to cure. This resistance leads to prolonged hospital stays, the need for more expensive treatments, and a higher risk of complications.

The Need for a Proper Medical Consultation

The dangers of self-medication can be avoided by seeking proper medical advice. A qualified healthcare professional is trained to assess the full range of symptoms, consider underlying conditions, and provide accurate diagnoses. As Dr. Eric Williams, an internal medicine specialist, emphasized, “Consulting a doctor before taking any medication is crucial to ensure the correct treatment.”

Doctors assess a patient’s medical history, provide appropriate guidance, and, if necessary, prescribe the right course of treatment. In cases of fever, for instance, which may be caused by a variety of factors ranging from infections to fatigue, self-medication may not address the root cause, potentially delaying treatment and leading to more severe health problems. This highlights the importance of professional medical consultation, particularly for persistent or unexplained symptoms.

Dr. Tushar Tayal, an internal medicine consultant, advised that patients should always consult a doctor before taking any medication, especially painkillers, antibiotics, or antacids. Even though these medications may seem harmless, they can cause significant health problems if misused. The rise of telemedicine and online consultations has made it easier to seek professional advice without the need for in-person visits, allowing individuals to stay safe and informed when managing their health.

A Safer Approach to Health

While self-medication may seem like a convenient solution, it carries serious risks that can undermine health and lead to long-term complications. From antibiotic resistance to liver damage and drug dependency, the dangers of taking medications without proper guidance are vast. It is essential for individuals to educate themselves about the risks of self-medication and always seek professional medical advice before taking any medication.

By prioritizing consultation with healthcare professionals and avoiding the temptation to self-medicate, individuals can protect their health and ensure that they are receiving the appropriate treatment. Furthermore, addressing the cultural and financial factors that drive self-medication, and promoting awareness about its dangers, can help reduce the prevalence of this harmful practice in India. Ultimately, safe and responsible use of medications is essential for ensuring long-term health and well-being.

1 in 3 Indians at Risk of Liver Disease: How to Stay Safe

by Dr. Shruthi R March 31, 2025

written by Dr. Shruthi R

Liver disease is becoming a major public health concern in India, with the Union Health Ministry highlighting that 1 to 3 out of every 10 Indians may have Non-Alcoholic Fatty Liver Disease (NAFLD). This condition, closely linked to obesity, diabetes, and heart disease, is on the rise, prompting updated guidelines to tackle the issue.

Maintaining a healthy liver requires a proactive approach. A balanced diet rich in fruits, vegetables, whole grains, and lean proteins is essential while avoiding processed foods, saturated fats, and excess sugar.

India Sounds Alarm Over US Tariffs on Pharma Exports

by Dr. Shruthi R March 31, 2025

written by Dr. Shruthi R

As the United States prepares to introduce new reciprocal tariffs, concerns are growing in India, particularly within its pharmaceutical sector. With India exporting over $9 billion worth of pharmaceutical products to the US annually—making up more than 31% of its total pharma exports—any potential tariffs could have a significant impact on the industry. The impending policy changes under the leadership of US President Donald Trump have raised alarms among Indian pharmaceutical companies, policymakers, and trade analysts, as they assess the consequences for one of India’s most vital export sectors.

The Importance of Pharmaceutical Exports to India

India is known as the “pharmacy of the world,” producing affordable generic medicines that serve both developed and developing nations. The pharmaceutical sector is a major contributor to India’s economy, accounting for approximately 2% of the country’s GDP and employing millions. The US is India’s largest market for pharmaceutical exports, purchasing high-quality generic drugs that help reduce healthcare costs for American consumers. Indian companies, including major firms like Sun Pharma, Dr. Reddy’s, Cipla, and Lupin, have established themselves as key players in the global pharmaceutical supply chain.

The Impact of Potential Tariffs

The proposed US tariffs on Indian pharmaceutical exports could disrupt the industry in several ways:

Increased Costs for Indian Exporters – Tariffs would make Indian drugs more expensive in the US, reducing their competitive advantage over domestic and other foreign pharmaceutical manufacturers.
Potential Job Losses in India – With reduced exports, Indian pharmaceutical companies may be forced to cut production, leading to layoffs and economic strain.
Higher Drug Prices for American Consumers – Indian generics help keep US drug prices low. If tariffs drive prices up, US healthcare costs could rise, affecting millions of patients who rely on affordable medicines.
Diversion to Alternative Markets – Indian pharmaceutical firms may look to expand into other regions, such as Africa, Latin America, and Europe, but replacing the lucrative US market will be challenging.

India’s Response and Countermeasures

The Indian government and pharmaceutical industry leaders are exploring options to mitigate the effects of these potential tariffs. Strategies being considered include:

Diplomatic Negotiations – India is engaging in discussions with US trade representatives to negotiate exemptions or reduce the impact of the tariffs.
Trade Agreements with Other Nations – India is working on strengthening trade ties with emerging markets to reduce dependency on the US.
Increasing Domestic Demand – Encouraging domestic consumption and boosting healthcare infrastructure in India can help balance any potential loss from exports.
R&D and Innovation – Indian pharma firms are investing in research and development to produce high-value drugs and biosimilars that can command better margins globally.

Global Implications

The US tariffs on Indian pharmaceuticals may have global consequences. Many developing nations rely on affordable medicines from India, and if Indian firms are forced to shift their pricing or production strategies, it could disrupt the availability of essential drugs worldwide. Additionally, US-based pharmaceutical companies that source raw materials or outsource production to India may also face increased costs.

The looming US tariffs on Indian pharmaceutical exports pose significant risks to both economies. While the Indian government and pharma industry are preparing contingency plans, the uncertainty surrounding these trade policies remains a pressing concern. With ongoing diplomatic efforts and strategic diversification, India aims to safeguard its pharmaceutical sector while maintaining its role as a global healthcare provider. However, the final impact will depend on the US administration’s stance and India’s ability to adapt to new trade realities.

Fake Dyed Kaali Dal from Himachal Raises Health Concerns: Know the Risks

by Dr. Shruthi R March 31, 2025

written by Dr. Shruthi R

Recently, reports of kaali dal (black gram) allegedly being dyed with synthetic chemicals in Himachal Pradesh have raised serious health concerns. Journalist Neha Sharma shared a video on Instagram, showing that the dal she purchased lost its black color after soaking overnight, revealing a greenish tint underneath.

This alarming discovery has sparked widespread discussions about food adulteration and its impact on health. Holistic health and wellness coach Isha Lall, in an interview with Indianexpress.com, explained the potential dangers of consuming counterfeit dals and how consumers can identify and choose safe, authentic products.

Health Risks of Consuming Fake Dyed Kaali Dal

The adulteration of food, especially with synthetic dyes and chemicals, poses serious health hazards. Here’s what happens to the body when you consume such contaminated dals:

1. Toxic Load on the Liver and Kidneys

Fake food dyes are often laced with heavy metals such as lead, arsenic, or mercury, which can accumulate in the liver and kidneys, leading to toxicity over time. The liver, being the body’s primary detox organ, has to work harder to filter out these toxins.

Prolonged consumption of such chemicals can lead to liver damage, kidney dysfunction, and metabolic issues.
Studies indicate that heavy metal exposure increases the risk of liver toxicity and kidney failure by up to 30%.

2. Digestive Problems and Gastrointestinal Distress

Synthetic dyes and chemicals irritate the digestive tract, disrupting normal gut function. Common gastrointestinal symptoms include:

Nausea, bloating, and indigestion
Acid reflux and stomach pain
Altered gut microbiome, leading to poor digestion

Ayurveda emphasizes maintaining digestive fire (agni) for overall health. Fake dyes interfere with this balance, weakening digestion and causing long-term gut health issues.

3. Cancer Risk from Harmful Chemicals

Some artificial food dyes have been linked to carcinogenic effects. The World Health Organization (WHO) has warned against excessive consumption of food-grade dyes like tartrazine, commonly found in adulterated foods.

Research suggests a connection between certain food dyes and increased cancer risks, especially in the stomach, colon, and liver.
Regular consumption of fake dyed dals may contribute to chronic inflammation, a key factor in cancer development.

How to Identify Fake Dyed Kaali Dal?

Given the risks, knowing how to differentiate between fake and authentic kaali dal is crucial. Here are a few practical methods:

1. Water Test

Soak a handful of dal in a glass of water for 20 minutes.
If the water turns dark, murky, or leaves colored residue, the dal is likely dyed with synthetic chemicals.
Authentic kaali dal will retain its natural color without excessive bleeding.

2. Rubbing Test

Take a few grains of the dal and rub them between your palms.
If the color transfers to your hands, it’s likely artificially dyed.
Genuine dal does not leave any unnatural residue.

3. Smell Test

Authentic kaali dal has a mild, earthy aroma.
Fake dyed dal may have a chemical or artificial smell, especially when washed.

4. Appearance Check

Natural kaali dal has an uneven surface and varied color tones.
Fake dal often appears uniformly dark, overly glossy, or unnaturally black, which suggests tampering.

Why Kaali Dal Should Be a Part of Your Regular Diet?

Despite concerns over adulteration, genuine kaali dal remains a nutritional powerhouse. It is one of the most nutrient-dense legumes, rich in protein, fiber, and essential minerals.

1. High Protein Content

One cup of cooked kaali dal provides 14 grams of protein, making it an excellent plant-based protein source for vegetarians and vegans.
Helps in muscle building, repair, and overall body strength.

2. Supports Digestion and Gut Health

15 grams of fiber per serving helps in smooth digestion and prevents constipation.
Prebiotic properties feed good gut bacteria, strengthening the immune system.

3. Boosts Iron Levels and Prevents Anemia

Rich in iron, essential for hemoglobin production.
Particularly beneficial for women, helping to prevent iron-deficiency anemia.
One serving covers nearly 20% of daily iron needs.

4. Controls Blood Sugar and Reduces Diabetes Risk

Low glycemic index (GI) helps stabilize blood sugar levels.
Prevents sudden insulin spikes, reducing the risk of type 2 diabetes.

5. Ayurvedic Benefits

In Ayurveda, kaali dal balances vata and cools pitta, promoting internal stability.
It is especially beneficial during colder months, providing warmth and nourishment.

What is the Government Doing About Food Adulteration?

Food adulteration is a serious concern in India. The Food Safety and Standards Authority of India (FSSAI) has issued guidelines and conducts regular inspections to ensure food safety. However, strict monitoring and consumer awareness are essential to prevent such fraud.

Government Measures:

FSSAI food testing laboratories frequently check for contaminants in food products.
Strict penalties for those found guilty of food adulteration.
Increased consumer education to help people identify fake and adulterated foods.

What Can Consumers Do?

Buy from trusted sources: Purchase dals from reliable brands or certified organic markets.
Perform home tests: Simple water or rubbing tests can help detect adulteration.
Report adulteration cases: Consumers should report suspicious food products to local authorities or food safety officials.

The case of fake dyed kaali dal from Himachal Pradesh is a stark reminder of the growing problem of food adulteration. While improvements in food safety regulations are ongoing, consumer awareness remains the first line of defense against contaminated foods.

Avoid blindly trusting market-bought dals—always check for authenticity using simple home tests.
Prioritize health by choosing organic and naturally processed lentils.
Spread awareness about the dangers of synthetic dyes and food fraud.

By staying informed and making conscious choices, we can protect ourselves and our families from the harmful effects of adulterated food products.

Scientists Confirm: 37°C Is No Longer the Standard Body Temperature

by Dr. Shruthi R March 31, 2025

written by Dr. Shruthi R

For generations, we have been taught that the normal human body temperature is 37°C (98.6°F). This standard dates back to the 19th century, when German physician Carl Reinhold August Wunderlich conducted extensive research on body temperature and determined that the average was 37°C. However, recent studies suggest that this number may no longer be accurate. Instead, the average body temperature has been gradually decreasing, raising new questions about human health, environmental factors, and physiological changes over time.

The Origins of the 37°C Standard

In 1868, Carl Wunderlich established 37°C as the average human body temperature after measuring over 25,000 patients’ temperatures in Leipzig, Germany. His findings became widely accepted, and for over a century, medical professionals used this number as the benchmark for determining whether a person had a fever or normal body temperature.

However, in the decades since Wunderlich’s study, medicine and technology have advanced significantly. Scientists now have access to more precise instruments and a larger pool of data across diverse populations. These advancements have led researchers to re-examine the accuracy of the 37°C standard and question whether human body temperature has changed over time.

Modern Research Challenges the 37°C Standard

Several modern studies indicate that the average human body temperature is lower than 37°C. One of the most significant studies on this topic was conducted in Palo Alto, California, where researchers analyzed body temperature readings from three different historical periods. The results showed that the average temperature has steadily declined over the past 150 years.

Key Findings from Recent Studies:

Palo Alto Study (2020)
- Researchers analyzed over 677,000 temperature measurements from U.S. veterans and historical records.
- The study found that the average body temperature is now 36.4°C (97.5°F)—lower than Wunderlich’s 37°C standard.
- The researchers concluded that body temperature has decreased by 0.03°C per decade since the 19th century.
UK Study (2017)
- A British study found that 37°C remains a common body temperature, but variations exist.
- Some participants had temperatures as low as 36.6°C (97.9°F), challenging the idea of a fixed standard.
Bolivia Study – The Tsimane People (2020)
- Researchers studied the Tsimane, an indigenous group in the Bolivian Amazon.
- Their average body temperature has been dropping by 0.05°C per year over the past 16 years.
- The current average among the Tsimane is 36.5°C (97.7°F).

These findings suggest that human body temperature is not static—it changes over time due to various environmental and physiological factors.

Why Is Body Temperature Decreasing?

Scientists believe that multiple factors contribute to this gradual decline in average body temperature. These factors include:

1. Improved Healthcare and Hygiene

One of the biggest changes since the 19th century is the dramatic improvement in public health, hygiene, and medicine.

Lower infection rates: In the past, frequent infections caused the body to work harder, raising body temperature. With the introduction of antibiotics, vaccines, and better sanitation, infections have become less common.
Reduced chronic inflammation: Long-term inflammation was more common in the past due to untreated infections and diseases. Today, modern medicine helps reduce inflammation, leading to lower overall body temperatures.

2. Climate Control and Modern Lifestyles

Technology has significantly changed the way humans regulate body temperature.

Heating and air conditioning: In the past, people were exposed to extreme temperatures, forcing their bodies to work harder to regulate heat. Today, indoor climate control keeps temperatures stable, reducing the need for the body to generate extra heat.
Clothing and insulation: People wear better-insulated clothing and use blankets, further reducing the body’s need to produce excess heat.

3. Changes in Metabolism and Nutrition

Metabolism plays a crucial role in regulating body temperature. Some scientists believe that:

Improved diets: People today have better access to food and improved nutrition, leading to more efficient energy use and less heat production.
Lower metabolic rates: A decline in metabolic rates over time may be contributing to lower body temperatures.

4. Evolutionary Adaptations

Some scientists propose that this change could be an evolutionary adaptation.

Over time, the human body may have adjusted to more comfortable living conditions, reducing the need for higher body temperatures.
This adaptation might be ongoing, meaning that future generations could see even lower average body temperatures.

Does a Lower Body Temperature Affect Health?

While a small decrease in average body temperature may not seem significant, it has important implications for medicine and healthcare.

1. Rethinking Fever and Illness Diagnosis

Doctors have long used 37°C as a baseline to determine if a patient has a fever. However, if normal body temperature is lower than previously thought, then fever thresholds might need to be adjusted.

Current fever threshold: A temperature above 38°C (100.4°F) is considered a fever.
New considerations: If normal body temperature is closer to 36.4°C, a fever might actually begin at a lower temperature than currently recognized.

2. Implications for Medical Research

Medical studies often rely on body temperature as a key indicator of health. A shift in average body temperature means that previous studies might need to be re-evaluated.

Conditions like thyroid disorders, infections, and metabolic diseases could be reassessed based on new temperature baselines.

3. Potential Benefits

Interestingly, a lower body temperature could have some positive effects on health.

Some studies suggest that a slightly lower body temperature is associated with a longer lifespan.
Lower temperatures reduce metabolic stress, potentially leading to slower aging and lower risks of age-related diseases.

Is 37°C Still a Useful Standard?

While the 37°C benchmark is deeply ingrained in medical practice, the evidence suggests that it is not an absolute standard for everyone. Instead, body temperature is influenced by:

Age (younger individuals tend to have higher temperatures)
Time of day (body temperature is lower in the morning and higher in the evening)
Activity levels
Individual differences (some people naturally run hotter or colder)

The idea of a fixed “normal” temperature may soon become outdated. Instead, medical professionals may adopt a more personalized approach, considering individual variations rather than relying on a universal standard.

A Changing Understanding of Normal Body Temperature

The belief that 37°C is the standard body temperature has been widely accepted for over 150 years, but modern research challenges this assumption. Studies from the U.S., UK, and Bolivia suggest that average human body temperature is actually lower today, likely due to improvements in healthcare, hygiene, and lifestyle changes.

This shift in body temperature is not just a minor statistical change—it has significant implications for medical diagnostics, fever thresholds, and our understanding of human physiology. As research continues, we may need to redefine what “normal” means when it comes to body temperature.

While 37°C will likely remain a useful reference point, the medical community is beginning to recognize that temperature is more variable than previously thought. Going forward, doctors and scientists will continue to refine their understanding of human body temperature, adapting to new findings and ensuring that medical standards reflect the most accurate and up-to-date research.
