A study has been released recently based on the analysis of the latest Global Burden of Disease (GBD) data that says that for 15 per cent of all deaths in Delhi in 2023 were caused by air pollution. The analysis was based on the data which was released by the Institute for Health Metrics and Evaluation (IHME) earlier this month. The data showed that around 17,188 deaths in the national capital were due to the long-term exposure to particulate matter (PM2.5) pollution. This is equivalent to 1 in 7 deaths in Delhi.

However, the Union Environment Ministry has said that there is "no conclusive evidence" that could directly link air pollution to mortality. The ministry said that it could be one of several contributing factors.

Toxic Air: A Public Health Emergency

Researchers at the Centre for Research on Energy and Clean Air (CREA), which analyzed the GBD data said the findings in fact point that there is a need to treat air pollution as a public health emergency.

Dr Manoj Kumar, who is an analyst at CREA said, "Air pollution must now be treated foremost as a public health issue, not just an environmental one. India already has over 250 epidemiological studies establishing the link between polluted air and a wide range of health impacts. The science is clear: what's needed now is decisive, coordinated action," said Dr Manoj Kumar, an analyst at CREA, as reported by NDTV.

How Can Someone Die By Air Pollution?

Particulate matter or PM2.5 and PM10 impacts human far beyond their lungs. When you inhale polluted air, the pollutants can travel from your lungs. It reaches the alveoli and enters the bloodstream. Overtime and after a long time of exposure, these particles could accumulate in blood vessels and reduce oxygen flow to heart and brain. This could trigger strokes, heart attacks, and other chronic illnesses.

Rise In Deaths By Air Pollution

As per the GBD data, air pollution related deaths in Delhi rose from 15,786 in 2018 to 17,188 in 2023. This is after the authorities had introduced several air quality management related plans. The deaths have been linked to high blood pressure and diabetes during the same period, however, those numbers are lower than air pollution.

Dr Kumar has also noted that the assumption most people have that air pollution is just a winter-specific problem is not right. Pollution is a year-round crisis, he points out and the "harmful exposure happens throughout the year". Dr Kumar notes that it is during winter when the speed drops and pollutants settle close to ground, which is why it becomes more visible during the winter.

According to CREA’s latest PM2.5 assessment for October 2025, Delhi emerged as the sixth most polluted city in India, logging an average PM2.5 level of 107 µg/m³ — nearly three times its September average. Haryana’s Dharuhera topped the list as the most polluted, with levels reaching 123 µg/m³. It is interesting to note that stubble burning's contribution in Delhi air pollution in October 2025 was 6% less than in other years.

Your hormonal health plays a huge role in your health, and if you think it is something you need to worry about only when you get older. However, that is not true; you must pay attention to it even if you are in your 20s. Dr Holly Miller, an American Board–certified obstetrician and gynecologists, shared a video explaining why it is important for youngsters to regulate their hormonal health.

Your twenties are a critical time for building the foundation of your long-term health, impacting everything from your fertility and metabolism to your overall well-being. Hormone balance is about more than just your menstrual cycle, it profoundly influences your skin, mood, energy levels, and even your long-term risk for conditions like PCOS or endometriosis.

5 Ways To Maintain Your Hormonal Health

Here are five evidence-based strategies to actively support your hormone health

Prioritize Deep, Consistent Sleep

Sleep is the time when your body performs essential repair and resets your hormonal systems. When you consistently get 7 to 9 hours of quality sleep, you stabilize cortisol, your main stress hormone.

High cortisol from lack of sleep throws off the production of reproductive hormones like estrogen and progesterone, which can lead to irregular cycles and worsen PMS. Think of a good night's sleep as the number one way to calm your internal chemistry and support the natural rhythm your hormones need to thrive.

Balance Your Blood Sugar

Rapid spikes in blood sugar trigger a rush of the hormone insulin to bring the sugar down. Over time, these frequent spikes lead to insulin resistance, a major driver of hormonal imbalances like PCOS. The key is to slow down sugar absorption.

When you eat carbohydrates like bread or fruit, always pair them with protein like eggs or chicken and healthy fat like avocado or nuts. This simple habit keeps your insulin levels steady and prevents the hormonal chaos caused by rollercoaster blood sugar.

Minimize Endocrine Disruptors

Endocrine-disrupting chemicals (EDCs) are hidden in many everyday products, from the lining of food cans (BPA) to synthetic fragrances and certain plastics. These chemicals are problematic because they can mimic or block your natural hormones, especially estrogen.

This interference can confuse your body, leading to heavy periods, unpredictable cycles, or fertility issues. Start simple: switch to using glass water bottles and food storage, choose fragrance-free products, and look for "paraben-free" labels on your skincare and makeup.

Engage in Regular Movement

Movement isn't just for weight loss, it is powerful hormonal medicine. Exercise, especially resistance training (lifting weights or using body weight), makes your cells much more responsive to insulin.

This means your body can process sugar more efficiently, which is vital for balancing all other hormones. Additionally, regular movement helps reduce body-wide inflammation, which is a primary cause of painful, uncomfortable period symptoms. Aim for a mix of strength training and light cardio throughout your week.

Fuel Up on Key Nutrients

Your hormones require specific building blocks and helpers to function optimally. Three critical nutrients are: Omega-3s, which are found in fatty fish/flaxseed, that reduce inflammation to ease cramps and mood swings.

Vitamin D, which acts more like a hormone itself and plays a role in regulating the menstrual cycle; and Magnesium, known as "nature's relaxant," which helps reduce PMS-related anxiety, migraines, and cramps. Focus on incorporating these vital fats and minerals into your diet every day to directly support better hormonal health.

Diabetologists are getting calls from all day long, but not for the doubts and patients one would imagine. These calls are from those who have been trying to lose and even before they would try the lifestyle changes the doctor suggests, they would jump in with the question that doctors are not very fond of, "Doctor, can you start me on weight-loss drugs?"

The BBC reports that a Mumbai-based diabetologist Dr Rahul Baxi also experienced something similar. A 23-year-old corporate employee walked into his clinic and told him that one of his friends was on weight loss jabs and if he would too, since he was worried about the 10kg he had gained. “Stop, and the weight comes back. Keep going, and without exercise you’ll start losing muscle instead. These medicines aren't a substitute for a proper diet or lifestyle change.”

These conversations have now become common in India, where people's demand for weight loss jabs have skyrocketed. India has world's second-largest population of overweight adults. Furthermore, more than 77 million people live with Type 2 diabetes in the country. This is thus no surprise that if the drug has gained a quick traction.

Game-Changing Drugs

“These are the most powerful weight-loss drugs we’ve ever seen… nothing compares to these,” says Dr Anoop Misra to BBC, who heads Delhi’s Fortis-C-DOC Centre for Diabetes and Endocrinology.

Two drugs dominate the market:

• Semaglutide, sold by Novo Nordisk as Rybelsus (oral) and Wegovy (injectable)
• Tirzepatide, sold by Eli Lilly as Mounjaro

Both belong to the GLP-1 class, which mimics the hormone that regulates appetite. By slowing digestion and acting on the brain’s hunger centres, the drugs make people feel full sooner and stay full longer.

Treatment usually starts with low doses and ramps up to a weekly maintenance dose. Early weight loss often appears within weeks, making the drugs especially attractive to young urban users wanting quick results.

Weight Loss Drugs Do Not Come Without Side Effects

Doctors warn that most users regain weight within a year of stopping. Without strength training or adequate protein intake, they also risk losing muscle instead of fat, particularly worrying in a country already battling sarcopenic obesity due to low-protein diets.

Side effects range from nausea and diarrhea to more serious risks like gallstones, pancreatitis, and significant muscle loss. And the drugs aren’t cheap: a month’s supply can cost ₹14,000–₹27,000, out of reach for most Indians.

India’s anti-obesity drug market has ballooned from $16 million in 2021 to nearly $100 million today. Novo Nordisk leads the market, while Eli Lilly’s tirzepatide quickly became India’s second-bestselling drug within months of launch.

But behind the buzz lies troubling misuse.

Doctors describe gym trainers, dieticians and beauty clinics recommending high-dose jabs without medical authority. Some online pharmacies deliver the drugs after minimal consultation. One Delhi-based doctor told the BBC that some colleagues had treated thousands of patients with imported, unregulated jabs bought on the black market.

Then there are “bridal slimming packages” and requests for rapid pre-wedding weight loss—some as drastic as dropping seven kilos in three months.

A new study revealed that childhood trauma could rewire’ your brain, the researchers suggest that this could lead to aggressive and self-harming behavior.

The study, led by Assistant Professor Sora Shin, identified the specific brain pathway that changes after someone experiences trauma early in life. The results were published in the journal Science Advances.

The researchers explained that their findings suggest that aggression and self-harm, while looking different on the outside, might actually come from the same place in the brain. They might both be a result of how the brain deals with pain signals.

Can Trauma Change Your Brain?

The new discovery is crucial because it’s the first time scientists have found a real biological process that explains how trauma, feeling sensitive to pain, and these harmful behaviors are all connected. This new understanding could lead to much more precise and effective treatments for people who struggle with conditions caused by trauma.

The researchers found that early trauma causes a specific communication line in the brain, linking the nucleus reuniens and the hippocampus, which is the pathway that regulates cognitive, executive and fear-learning process, to become overactive.

The increased activity of structures called calcium channels is what makes a person more likely to be aggressive and hurt themselves.

Both feeling upset and hurt physically seem to trigger these behaviors because the brain’s signals have been changed by trauma.

How Does Childhood Trauma Lead To Aggression?

Shin and her team research how bad experiences in childhood change the brain, leading to harmful behaviors in adulthood. Her previous work looked at how trauma can lead to things like binge eating.

Researchers questioned what really drives aggression and self-harm. Is it just feeling anxious or depressed? Or could there be a deeper reason, possibly related to how the brain handles pain, at the very core of these issues?

They explained that the trauma literally increased the activity of the calcium channel. The trauma changed the brain at a molecular level, causing the neuron to become hyperactive, meaning it was firing too much. This excessive activity in that specific circuit is what makes a person more susceptible to becoming aggressive and hurting themselves.

The research also suggested that pain, including emotional pain, might act as the doorway for these harmful behaviors to appear. By clearly identifying the physical connection in the brain between early trauma and its later effects, the study gives a much deeper understanding that goes beyond just asking people how they feel.

How Is Aggression and Self-Harm Linked?

In people who have gone through early childhood trauma, aggression and self-harm often happen at the same time. Doctors and therapists have known about this link for a while, mostly based on what patients tell them and what they observe in clinics.

To back this up, studies show that people who are treated for self-inflicted injuries are five times more likely to also be extremely aggressive. This strongly suggested that there was a single, underlying reason connecting the two behaviors.

Can This Help Treat Trauma?

Shin noted that extreme aggression is a serious social problem, and self-harm is a major concern for many people seeking treatment. She believes that their study provides clearer, more objective insights into the brain circuits that cause these outcomes. This understanding could eventually lead to the creation of more effective therapies to help people dealing with trauma's lasting impact.
