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

Chai and pakoras are practically non-negotiable once the rains set in. For a large number of Indians, though, monsoon comes with something less welcome: a blocked nose, itchy eyes, and a "cold" that just won't quit.

Most people write this off as a seasonal cold. It's often not. A large share of the patients I see in July aren't fighting a fresh infection. They're dealing with allergic rhinitis that's been present for months at a manageable level, and monsoon has simply pushed it past a threshold they can no longer ignore.

A Bigger Problem Than It Looks

The scale of this is easy to underestimate. A national study under the Global Asthma Network, which surveyed more than 1.27 lakh children, adolescents, and adults across India, found that close to a quarter of Indian adolescents aged 13 to 14 live with allergic rhinitis. Roughly one in ten adults does too.

Other Indian research puts the overall incidence of allergic rhinitis anywhere between 20 and 30 percent of the population. This isn't a niche complaint. It's one of the more common chronic conditions walking through general practice doors, most of which are simply unnamed.

Mostly Undiagnosed, Rarely Treated Right

The same national study found something more concerning: nearly three out of four people who met the clinical criteria for allergic rhinitis had never actually been diagnosed with it. Many had lived with recurring congestion, sneezing, and disturbed sleep for years without anyone connecting the dots.

A separate survey of over 1,600 physicians across India found that while a large share see allergic rhinitis routinely in practice, more than half had never used immunotherapy, one of the few treatments that changes the course of the disease rather than just quieting it temporarily.

Why Monsoon Makes It Worse

Indian allergen-testing data show a clear rotation of triggers through the year: dust mites dominate winter, pollens dominate summer, and fungal and insect allergens rise sharply once the rains set in.

The reason is straightforward. Once relative humidity in a city climbs past 70 percent, which happens routinely through the monsoon, fungal spores and dust mites both multiply fast. Waterlogging pushes fungal spore counts up further. A damp curtain or a mattress that never quite dries between showers becomes a long-term allergen source that outlasts any single rainy day.

It Rarely Comes Alone

Allergic skin and eye conditions tend to flare with the same seasonal humidity and allergen load as allergic rhinitis, and in practice, they rarely show up in isolation. A patient with monsoon-triggered nasal symptoms is worth a closer look for coexisting asthma, eczema, or conjunctivitis, simply because in the Indian patient population, these conditions travel together more often than not.

What Actually Helps

For anyone with a known allergic condition, a few habits make a real difference once the rains arrive:

• Start early. Begin or review your antihistamine or inhaled treatment before the monsoon sets in, not after symptoms flare. Allergic inflammation is far easier to control early than to bring down once it's escalated.
• Keep the fabric genuinely dry. Bedding, curtains, and upholstery that stay even slightly damp become breeding grounds for the mold and dust mites driving most flares. Check for indoor allergens rather than just blaming obvious outdoor ones.
• Ventilate or dehumidify. Especially in bedrooms, where hours of overnight exposure do the most damage.
• Keep rescue medication accessible through the season, not just on bad days.
• Don't wait out a flare that lasts beyond a week. That's usually the point where a proper allergy workup is overdue.
• If it happens every single monsoon, that pattern itself is a diagnosis worth acting on, not just enduring.

Monsoon doesn't create new allergy patients. It reveals how well the existing ones are actually being looked after.

Even a mild case of COVID-19 may trigger long-lasting eye problems, with new research revealing that persistent inflammation and nerve damage could be responsible for symptoms that standard eye tests often fail to detect.

The study, led by researchers at Linköping University in Sweden and published in Nature Communications, sheds light on why some COVID-19 survivors continue to experience debilitating vision issues months or even years after infection.

The research began after people who had recovered from mild COVID-19 sought medical help for persistent eye complaints. Many reported:

• Severe eye pain
• Light sensitivity (photophobia)
• Difficulty reading and focusing
• Extreme eye fatigue

Many participants said the condition significantly disrupted their daily lives, preventing them from working or continuing their education.

What the Study Found

Researchers evaluated 100 people who developed eye problems after mild COVID-19 but had never been hospitalized. Their symptoms had persisted anywhere from three months to three years.

The findings were compared with those of 32 people who had recovered from mild COVID-19 without developing eye symptoms.

Using advanced imaging and laboratory techniques, researchers identified several abnormalities that conventional eye exams failed to detect.

Persistent Inflammation and Nerve Damage

The study found evidence of:

• Long-term inflammation in the eyes
• Damage to nerves controlling multiple eye functions
• Abnormal immune activity involving T cells
• Changes in proteins found in tear fluid

Lead author Petros Moustardas, senior research associate at Linköping University, said the findings indicate that COVID-19 may trigger a severe immune reaction in the eyes, resulting in chronic inflammation and nerve dysfunction.

Why Light Sensitivity Happens

One of the most common complaints among participants was extreme sensitivity to light. Researchers found that their pupils were allowing too much light into the eyes because of impaired nerve control.

This abnormal pupil function was also associated with:

• Headaches
• Difficulty reading
• Trouble maintaining focus

An Unusual Eye Movement Disorder

The study also identified impaired coordination between the two eyes.

Some participants developed adult-onset strabismus—commonly known as crossed eyes—a condition that is rare in adults.

Researchers believe this occurred because COVID-19 affected the nerves responsible for controlling eye muscles.

A New Way to Diagnose COVID-Related Eye Problems

Because routine eye tests often miss these abnormalities, the research team developed two diagnostic models.

The first relies on specialized ophthalmic tests available at advanced eye clinics, while the second combines these examinations with tear fluid protein analysis to improve diagnostic accuracy.

Researchers hope these models will help doctors recognize COVID-related eye syndrome earlier and pave the way for future treatments.

"We found that the problems experienced by those affected were not detectable by standard tests. We had to perform specialised examinations to detect deviations. The puzzle pieces then fell into place, and we found explanations for the symptoms," said Neil Lagali, professor of experimental ophthalmology at Linköping University.

He added that while the findings provide important clues about how COVID-19 affects the eyes, more research is needed to develop effective treatments for those living with persistent vision problems.

Plant-based Vitamin D3 is often marketed as a healthier or superior alternative to traditional supplements, but doctors say that's not necessarily the case.

According to Dr. Murtaza S. Bagwala, Head of Emergency Medical Services at Saifee Hospital in Mumbai, existing research shows that plant-based Vitamin D3 is just as effective as conventional Vitamin D3 in increasing the body's vitamin D levels.

"Current evidence suggests that plant-based Vitamin D3 performs similarly to conventional Vitamin D3 supplements. For people who prefer vegan or plant-based products, it is a suitable alternative," he told HealthandMe.

Echoing this view, Dr. Sudhir Kumar, Neurologist at Apollo Hospitals in Hyderabad, said that plant-derived Vitamin D3—usually obtained from lichen, algae, or modern fermentation methods—provides an animal-free option without sacrificing effectiveness.

In a post on X, he noted that while plant-based Vitamin D3 is welcome news for vegans and those seeking cruelty-free supplements, both forms work equally well. He added that there is no medical need for people to switch if they are already taking conventional Vitamin D3 supplements.

India has approved its first plant-based Vitamin D3 (cholecalciferol) ingredient, a move that could expand options for food fortification and dietary supplements while addressing the country's widespread Vitamin D deficiency.

The Food Safety and Standards Authority of India (FSSAI) has cleared VITADEE Green, developed by Fermenta Biotech, for use in health supplements, nutraceuticals and food products.

The company stated that the ingredient is produced using an India-patented process and offers a sustainable, scalable and vegetarian-friendly source of Vitamin D3.

The approval allows Indian manufacturers to incorporate the ingredient into fortified foods, beverages and dietary supplements.

It is particularly significant for vegetarians and vegans, who have traditionally had limited access to Vitamin D3 because most supplements are derived from lanolin, a by-product of sheep's wool.

The approval also supports India's broader efforts to improve nutrition through food fortification, an area where experts say Vitamin D remains a major gap.

What Is Vitamin D3?

Vitamin D3, often called the "sunshine vitamin," is produced by the body when the skin is exposed to sunlight.

It helps the body absorb calcium, maintain healthy bones and teeth, and lowers the risk of fractures. In children, severe deficiency can lead to rickets, while in adults it increases the risk of osteoporosis, muscle weakness, and falls.

Beyond bone health, Vitamin D3 also supports immune function. Research suggests low Vitamin D levels may be associated with increased susceptibility to infections and higher levels of inflammation.

Who Should Take Vitamin D3 Supplements?

The experts said the key question is whether supplementation is needed, not whether the source is plant- or animal-derived.

"The source matters mainly for ethical, dietary or personal preference—not for efficacy," Dr. Sudhir said.

Dr. Bagwala cautioned against taking high-dose Vitamin D without medical advice, as excessive intake can raise calcium levels and increase the risk of kidney stones and other complications.
