The clothes you wear when you work out may do you more harm than helping you to stay healthy as you hit the gym. This is because research has revealed alarming levels of bisphenol A (BPA), a chemical compound linked to significant health risks in several sports wear, including sports bra, leggings, and athletic wear. The Center for Environmental Health (CEH), which is a nonprofit consumer advocacy group has brought these concerns to light, and have raised awareness about the potential danger and damage these sports wear can cause because of the common chemicals used.

What is BPA? Is it concerning?

Bisphenol A, or BPA is a chemical that is used to make plastics and resins. It is also used in certain fabrics and is known for its endocrine-disrupting properties, which can also interfere with one's hormonal balance. There have been studies, including a 2019 study titled The adverse health effects of bisphenol A and related toxicity mechanisms that have linked BPA exposure to various health problems, including asthma, cardiovascular diseases, obesity, diabetes, and even cancer.

Many of research which have been conducted focus on the ingestion, which can happen when you store food in BPA-lined containers. Among them, some of the more recent studies show that skin absorption is also a pathway. This means when you are handling receipts which are printed on thermal paper, or wear BPA-containing fabrics, the chemical can seep through your skin and enter your bloodstream.

Though it is also true that BPA is exposed from the body within days, however, continuous exposure from multiple sources can be concerning.

Sports Wear and the harm it may cause you

CEH also tested popular athletic wear in October 2023 and found BPA levels were exceeding California's safety standards by as much as 22 times.

Testing also showed that top brands contained up to 40 times the permissible limit of BPA.

What do the laws say?

As far as laws are concerned, under California's Proposition 65, the maximum allowable dose for BPA exposure via skin is 3 micrograms per day. While this law is among the strictest in the United States, it highlights a broader issue of chemical safety in consumer products nationwide.

Ana Soto, an immunologist with decades of research on BPA, even low doses of dermal and oral exposure can combine to create a significant health risk. She also warned that prolonged exposure through fabric, especially when you are exercising, as your pores are open and sweat is present, can in fact, amplify these effects.

How does BPA affect your health?

BPA can disrupt your body's endocrine system, which is a network of glands and organs that produce hormones that control many bodily functions. These include growth and development, metabolism, and reproduction, to name a few. BPA can mimic natural hormones like estrogen and interfere in those bodily functions.

Studies also link it with obesity and diabetes, respiratory issues, especially asthma risk in school-aged children, cardiovascular diseases, and cancer risks.

How can you be safe?

There are certain steps you can follow to protect yourself:

• Avoid wearing BPA-lined sports-wear
• Change immediately after your workout
• Do not wear sports-wear for an elongated period

In today's fast-paced world, stress has become an unavoidable part of life. While short-term stress can help us stay alert and respond to challenges, prolonged or chronic stress can have a significant impact on brain health.

On the occasion of World Brain Day, it is important to raise awareness about how unmanaged stress can silently affect memory, concentration, emotional well-being, and overall quality of life.

How Chronic Stress Affects the Brain

When the body is under constant stress, it releases higher levels of cortisol, commonly known as the stress hormone. Persistently elevated cortisol can interfere with the normal functioning of the brain, particularly areas responsible for learning, memory, and decision-making.

Individuals may experience forgetfulness, difficulty concentrating, reduced productivity, irritability, anxiety, and disturbed sleep. If left unaddressed, chronic stress may also increase the risk of depression and other mental health disorders.

How to Protect Your Brain from Stress

The good news is that the brain has an incredible ability to recover when stress is managed effectively. Adopting healthy lifestyle habits such as regular physical activity, adequate sleep, mindfulness practices, balanced nutrition, and maintaining meaningful social connections can significantly reduce stress levels and protect brain function. It is equally important to recognize when stress becomes overwhelming and seek timely professional support.

Prioritize Brain Health

Brain health is just as important as heart health, and taking care of our mental well-being should never be overlooked. This World Brain Day, let us prioritize stress management as an essential part of a healthy lifestyle. By identifying the early signs of chronic stress and making positive lifestyle changes, we can preserve memory, improve focus, enhance emotional resilience, and ensure a healthier brain for years to come.

White sugar is widely known for its harmful effects on health. As a result, many people—especially those with Type 2 diabetes—turn to low- and no-calorie sweeteners such as aspartame, saccharin, and erythritol, believing they are a healthier alternative.

However, a new study published in Neurology, the medical journal of the American Academy of Neurology, has again suggested that higher consumption of certain artificial sweeteners may be associated with faster declines in memory and thinking skills over time.

The researchers stressed that the findings do not prove these sweeteners cause cognitive decline. Instead, they show an association, meaning other factors could also contribute to the observed pattern.

"Low- and no-calorie sweeteners are often seen as a healthy alternative to sugar. However, our findings suggest certain sweeteners may have negative effects on brain health over time," said study author Claudia Kimie Suemoto from the University of São Paulo, Brazil.

What Did the Study Find?

The study followed 12,772 adults in Brazil, with an average age of 52 years, for approximately eight years. Researchers examined the intake of seven commonly used low- and no-calorie sweeteners:

• Aspartame
• Saccharin
• Acesulfame K
• Erythritol
• Xylitol
• Sorbitol
• Tagatose

These sweeteners are commonly found in ultra-processed foods and beverages, including flavored water, soft drinks, energy drinks, yoghurt, desserts, and products marketed as low-calorie. Many are also sold separately for use in coffee, tea, cooking, and baking.

The researchers found that people with the highest total intake of sweeteners experienced a 62% faster decline in overall thinking and memory abilities than those with the lowest intake. This difference was estimated to be comparable to about 1.6 additional years of brain ageing.

Participants in the middle consumption group also showed a 35% faster decline, equivalent to approximately 1.3 additional years of ageing.

The association was especially strong among people with diabetes, who are more likely to use artificial sweeteners as sugar substitutes.

Stronger Link in Adults Under 60

Age also appeared to influence the findings. Among participants younger than 60, those who consumed the highest amounts of sweeteners experienced faster declines in verbal fluency and overall cognitive performance than those with the lowest intake.

Researchers did not observe the same association among participants aged 60 years and older. The study found that aspartame, saccharin, acesulfame K, erythritol, sorbitol, and xylitol were associated with faster declines in overall cognition, particularly memory. Tagatose was the only sweetener not linked to cognitive decline.

"While we found links to cognitive decline for middle-aged people both with and without diabetes, people with diabetes are more likely to use artificial sweeteners as sugar substitutes," Suemoto said. "More research is needed to confirm our findings and to investigate if other refined sugar alternatives, such as applesauce, honey, maple syrup or coconut sugar, may be effective alternatives."

Are There Any Limitations?

The researchers also acknowledged several limitations in study :

• It did not evaluate every artificial sweetener currently used in foods and beverages, so the findings cannot be applied to all sugar substitutes.
• Dietary intake was self-reported, meaning participants may have inaccurately remembered or estimated what they consumed.
• The study was observational, meaning it identified an association but cannot establish that artificial sweeteners directly caused cognitive decline.

Brain disorders are becoming one of India's fastest-growing public health challenges, said health experts ahead of Brain Day on July 22.

The experts highlighted that an ageing population, rising lifestyle diseases and limited access to specialist care are contributing to an increasing burden of conditions such as stroke, epilepsy, Parkinson's disease, dementia and multiple sclerosis.

Access Gap Delays Diagnosis, Treatment

Dr. Madhukar Bhardwaj, Director & Head of Department, Neurology, Aakash Healthcare, said neurological disorders have become one of India's most urgent healthcare concerns.

"Neurological disorders are no longer a concern of a small section of the population—they are one of the most pressing emerging healthcare challenges of our time. In a country as vast and diverse as India, with a rapidly ageing population, this is a matter of urgency. What makes the situation even more worrying is the lack of equitable access to care," he said.

According to the World Health Organization's Global Status Report on Neurological Disorders (2025), India faces a severe shortage of neurologists, with the neurologist-to-patient ratio nearly 80 times worse than in high-income countries, leaving specialist care concentrated in major cities.

Stroke Increasingly Affects Younger Adults

Experts also highlighted a worrying shift in disease patterns, with strokes increasingly affecting younger people. Dr. Bhardwaj said strokes, once considered a disease of older adults, are now being seen more frequently among people in their 30s and 40s, underscoring the need for greater awareness and prevention.

Lifestyle Diseases Driving Brain Disorders

Doctors identified uncontrolled hypertension, diabetes, obesity, smoking, chronic stress, physical inactivity and poor sleep as major contributors to the rising burden of neurological diseases.

Dr. Rajas Deshpande, Consultant and Head of Neurology, Jupiter Hospital, Pune, said many neurological conditions share common lifestyle-related risk factors.

"Controlling hypertension, diabetes, obesity, smoking and physical inactivity can significantly reduce the risk of stroke and vascular dementia. Prevention deserves as much attention as treatment because many neurological disorders share common modifiable risk factors," he said.

Early Diagnosis Can Improve Outcomes

Dr. Bhardwaj stressed that many neurological disorders progress silently, making early diagnosis critical.

"Whether it is stroke, epilepsy, Parkinson's disease or memory disorders, early diagnosis can significantly improve outcomes. Unfortunately, many patients seek specialist care only after the disease has advanced, either because symptoms are ignored or because neurological services are not easily accessible. Greater public awareness and timely referrals are essential," he said.

Brain Health Linked to Women's Reproductive Health

Experts also emphasized that brain health extends beyond cognition. Dr. Hrishikesh Pai, Consultant Gynecologist & IVF Specialist, Lilavati Hospital Mumbai and Fortis Hospitals Delhi & Chandigarh, said the brain plays a central role in regulating women's reproductive health.

"Brain health plays a critical role in women's reproductive health. The hypothalamus and pituitary gland in the brain regulate the hormonal signals that control menstruation, ovulation, and pregnancy," he said.

He added that chronic stress, neurological disorders, pituitary diseases and certain medications can disrupt hormonal balance, leading to irregular menstrual cycles, infertility and pregnancy-related complications.
