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

As India steps into 2026, two familiar yet unsettling names have returned to the public health conversation. Nipah virus cases reported from West Bengal and fresh bird flu detections among crows in Bihar have raised questions about how dangerous these infections really are for humans. While both diseases originate in animals and can cross over to people, their risks, spread patterns and fatality levels are very different.

Two zoonotic threats, very different risks

Nipah virus and avian influenza are both zoonotic, meaning they jump from animals to humans. Beyond that similarity, the comparison largely ends. Nipah is rare but extremely lethal when it infects humans. Bird flu, on the other hand, spreads widely among birds and poultry, but only occasionally infects people.

Health experts note that understanding this distinction is crucial. Nipah alarms public health systems because even a small cluster of cases can lead to severe illness and death. Bird flu triggers large scale surveillance mainly due to its impact on poultry and the economy, with human cases remaining uncommon.

Nipah virus and why it worries health officials

The Nipah virus was first identified in Malaysia in the late 1990s and has since caused multiple outbreaks in South and Southeast Asia. Fruit bats are its natural carriers, and humans can get infected through contaminated food, contact with infected animals or close contact with an infected person.

Symptoms often begin like a common viral illness, with fever, headache and cough. In many patients, the disease progresses rapidly. Within days, some develop encephalitis, seizures, confusion and coma. Respiratory distress is also common in severe cases.

According to the World Health Organization, Nipah’s fatality rate ranges between 40 and 75 percent, depending on the outbreak and access to timely medical care. There is no approved vaccine or specific antiviral treatment. Doctors rely on intensive supportive care, which makes early detection and isolation critical.

In January 2026, West Bengal reported multiple Nipah cases, prompting contact tracing and monitoring of nearly 200 people. Most tested negative, and the WHO assessed the risk of wider spread as low. Still, the high death rate keeps Nipah firmly on India’s list of priority pathogens.

Bird flu and its limited human impact

Bird flu, or avian influenza, is caused by influenza A viruses that primarily infect birds. Strains such as H5N1 and H9N2 have been detected repeatedly in India among poultry and wild birds. Bihar’s Darbhanga district recently reported thousands of bird deaths, triggering containment measures.

Humans usually get infected through close contact with sick or dead birds or contaminated environments. When infection does occur, symptoms can resemble seasonal flu at first, but severe cases may progress to pneumonia or acute respiratory distress.

Some bird flu strains have shown high fatality rates among confirmed human cases, sometimes close to 50 percent. However, experts stress that these numbers come from very small case counts. Sustained human to human transmission remains rare, which limits large outbreaks in people.

Which virus is deadlier for humans?

In terms of individual risk, Nipah virus is considered deadlier for humans. Its consistently high fatality rate, lack of treatment options and potential to cause severe brain inflammation make it especially dangerous, even when case numbers are low.

Bird flu poses a broader threat to animal health and livelihoods, but its direct impact on human life has so far been limited. Public health officials continue to monitor both closely, knowing that vigilance, early reporting and strong surveillance are the best tools to prevent either virus from spiralling into a larger crisis.

After the death of 150 crows in Bihar's Bhagalpur district in Naugacha, sudden death of 1,500 crows in Chennai, in Tamil Nadu has again raised concerns over bird flu. At the center of all these is Highly Pathogen Avian Influenza or the HPAI, which is also known as bird flu or the A H5N1 virus. While the strain is known for being notorious and have jumped states, spreading outbreaks in many Indian states, including Jharkhand, Bihar, Maharashtra, Andhra Pradesh, Kerala, Telangana, and Tamil Nadu, the concerns do not end there. Many are concerned if it is a threat to humans too.

Can H5N1 Virus Infect Humans?

As per the World Health Organization (WHO) data, between January 2023 and December 2025, a total of 993 human cases of avian influenza were reported in 25 countries. Almost half of them, which is around 477 people, died. The virus has a fatality rate of 48 per cent.

Two different studies, one done by the universities of Cambridge and Glasgow that show how avian flu strains are multiplying even when the body temperatures could hinder viruses. Whereas, another important study led by Indian scientists, by Philip Cherian and Gautam Menon of Ashoka University, published in BMC Public Health predict if H5N1 or the bird flu virus, could start spreading among humans. How quickly must we act to stop it?

Can H5N1 Virus Infect Humans? How It Survives In The Body?

Human influenza viruses infect many each year. The seasonal strains we see most often fall under influenza A and tend to do well in the cooler temperatures of the upper respiratory tract, which is close to 33°C. They are less suited to the warmer, deeper parts of the lungs, where temperatures reach about 37°C.

As per Science Daily, when the body cannot slow an infection, the virus continues to multiply and spread, which can lead to more serious illness. Fever acts as a protective response, pushing body temperature as high as 41°C. Until now, the exact reason why fever slows some viruses but not others has been unclear.

Avian influenza behaves differently. These viruses usually grow in the lower respiratory tract, and in their natural hosts, such as ducks or seagulls, they often infect the gut. Temperatures in these areas can reach 40°C to 42°C, which helps explain their greater tolerance to heat.

Can H5N1 Virus Infect Humans? What Does The India Specific Study Reveal?

Using BharatSim, an open-source simulation platform originally developed during Covid-19, the researchers recreated what an outbreak might look like in real life. “The threat of an H5N1 pandemic in humans is a genuine one,” Prof Menon said, “but we can hope to forestall it through better surveillance and a more nimble public-health response.”

Their model begins where experts believe a real outbreak would: with a single human infection, most likely a poultry worker or someone exposed to infected birds at a farm or market. The danger, the researchers argue, lies not in that first case, but in whether sustained human-to-human transmission takes hold.

The study by Ashoka University has the most sobering findings in how fast control can slip away. According to the simulations, once cases rise beyond roughly two to ten people, the virus is likely to move beyond immediate contacts and into the wider community.

If households of close contacts are quarantined when just two cases are detected, the outbreak can almost certainly be contained. By the time ten cases are identified, however, the model suggests the infection has probably already spread far enough that early interventions no longer make a meaningful difference.

To ground their work in reality, the researchers focused on a village in Tamil Nadu’s Namakkal district, one of India’s largest poultry hubs. With more than 1,600 farms, around 70 million chickens and tens of millions of eggs produced daily, the region reflects the kind of dense human-animal interaction where spillovers are most likely.

In the simulation, the virus spreads outward from a single workplace into homes, schools and markets, tracking primary and secondary contacts. Once “tertiary” infections, contacts of contacts, appear, control becomes dramatically harder without severe measures such as lockdowns.

Can H5N1 Virus Infect Humans? What Works And What Does Not Work

Culling birds work, but only if it happens before humans are infected. Once the spillover is done, isolating patients and quarantining is the only option that can stop the virus, that too if done very early. Targeted vaccination could help raise the threshold at which the virus can sustain itself. Quarantine imposed too early keeps families together longer, increasing household transmission. Imposed too late, it barely slows the outbreak at all.

What won't people do to get that gold. In the quest for so, Olympians re injecting hyaluronic acid in their penises. The reason? For skiing, it helps them fly better and further.

In January, a German newspaper, Bild reported that jumpers were injecting, what now is dubbed as Penisgate in their penis. The newspaper claimed that athletes inject the acid in the penis before they are measured for their suits.

Hyaluronic acid is used for cosmetic surgery, especially as a filler. Surgeons have also used it for penile girth enlargement. This is exactly why it is being used by the Olympians.

Injecting hyaluronic acid will increase the penile girth. However, experts point out that this means, one has to insert a lot of it in the penis to have this worked out. It is not a permanent solution, and can only last up to six to 12 months, depending on the absorption.

Inserting this will increase the penile girth or the penis circumference by one or two centimeters. As per the International Ski and Snowboard Federation, FIS, the surface area of their suits during competition could be increased by this, which increases their flight in the air, reported BBC.

"Every extra centimetre on a suit counts. If you suit has a 5% bigger surface area, you fly further," said FIS ski jumping's men race director Sandro Pertile, reported by BBC.

Ahead of each season, ski jumpers undergo measurements using 3D body scanners and are required to wear only elastic, body-tight underwear during the process.

Regulations allow suit measurements a tolerance of just 2–4 cm. As part of this assessment, athletes’ crotch height is also recorded. The suit’s crotch height must match the athlete’s own measurement, with an additional 3 cm permitted for men.

Hyaluronic acid injections into the penis can last for up to 18 months.

Athletes have previously faced scrutiny for attempting to boost performance through alterations or manipulation of their suits.

Experts caution that penile injections using hyaluronic acid can pose serious short- and long-term risks.

They warn that improper technique or incorrect dosing may lead to pain, disfigurement, deformity, infection, inflammation, altered sensation, and sexual dysfunction. In rare cases, infections can worsen, causing tissue death (gangrene) and even loss of the penis.
