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.
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.
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.
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.
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.

Across social media, videos of mothers shaving their daughters’ upper-lip hair have been going viral. In many clips, parents say they are trying to protect their children from bullying about facial hair, something many women recall experiencing during their own childhood. Some of these videos show girls as young as 10 or 12 getting their first facial shave at home.
The conversation gained major traction in 2023 when influencer Vidya Gopalan posted a video of herself shaving her 12-year-old daughter’s facial hair. The clip clocked millions of views and sparked strong reactions. While many viewers praised the mother for being proactive, others felt the practice introduces children to beauty pressures far too early.
Similar videos continue to trend today, often framed as an act of care from parents who want their children to feel confident. But dermatologists say the issue is more complicated than it looks online.
Experts point out that children’s skin is very different from adult skin. The protective barrier is still developing, which means it is more vulnerable to irritation and injury.
When shaving is done too early or too frequently, it can cause redness, cuts, razor bumps and sometimes infections. Using adult razors, dull blades or harsh products can make the situation worse. Even small nicks on delicate facial skin can lead to inflammation or long-lasting irritation.
Dermatologists note that shaving itself is not inherently dangerous if done correctly and occasionally. However, it should not become a routine practice for very young children simply because it is trending online.
Instead, any decision about hair removal should be taken carefully, with proper hygiene and supervision.
One reason many parents feel comfortable allowing shaving is the belief that hair will grow back thicker anyway, so removing it early does not change much.
Experts say this idea is a long-standing myth.
When hair regrows after shaving, the blunt edge of the cut hair can make it appear darker or thicker. In reality, the hair shaft itself has not changed. Studies in dermatology have repeatedly shown that shaving does not alter hair thickness, color or growth rate.
However, frequent shaving may still irritate sensitive skin, which is why dermatologists recommend caution when it comes to young children.
The debate intensified further after reports surfaced about an eight-year-old undergoing laser hair removal. That revelation shocked many people online and pushed the conversation beyond simple grooming.
Dermatologists stress that laser hair removal is generally designed for teenagers or adults whose hormones have stabilized. During childhood, hair growth patterns can still change significantly as the body develops. Because of this, such procedures are rarely recommended for younger children.
The concern is not only medical but also psychological. Starting cosmetic treatments too early may reinforce the idea that natural body features need to be “fixed.”
Experts say the larger conversation should not revolve only around hair removal techniques. It should also address how children learn to view their bodies.
Facial hair during puberty is normal, and it varies widely depending on genetics and hormones. In countries like India, where darker hair is common, many children may notice upper-lip hair earlier than their peers.
Instead of immediately removing it, dermatologists encourage parents to talk openly with their children about body changes. Helping children build confidence and understand that these changes are natural can be just as important as addressing appearance concerns.
If a child feels genuinely uncomfortable, gentler options such as a soft facial trimmer or consulting a dermatologist may be considered. But experts say the goal should not be to rush into grooming habits simply because social media has normalized them.
Sometimes, the most important step is helping children realize that their bodies are not a problem that needs fixing.

An international team of researchers has developed an artificial intelligence (AI)-based tool that can significantly improve care for glaucoma -- a leading cause of irreversible blindness worldwide, according to a study published in The Lancet Primary Care journal today.
Researchers led by those from the University of Lisbon in Portugal found that the AI-based screening tool halved the number of unnecessary referrals for glaucoma.
The study, released during the Glaucoma Awareness Week, also showed an accuracy level at par with human eye doctors.
"The high accuracy at excluding people without glaucoma is especially important, as false alarms can lead to unnecessary hospital visits, patient anxiety, and added strain on healthcare services," the researchers said.
According to the researchers, AI-based screening could:
The study was carried out at a single screening center in Lisbon, Portugal, in 2023.
The experts screened 671 adults aged 55-65 for glaucoma via the AI tool, analyzing images of the eyes. The images were then independently graded by six glaucoma experts.
The AI-tool:
While modelling studies suggest that screening could substantially reduce glaucoma-related visual impairment and blindness, barriers include the need for specialised diagnostic equipment and trained personnel, particularly in low- and middle-income countries, and the intrinsically low positive predictive value of screening tests.
In such a scenario, the new study showed that "AI may provide a more viable option than population-wide screening", which may seem impractical.
Glaucoma is a chronic disease that affects an estimated 80 million individuals globally, according to the World Glaucoma Association.
It is a progressive, degenerative disorder of the optic nerve that produces characteristic visual field damage.
The disease stems from a long asymptomatic phase, resulting in substantial underdiagnosis and delayed treatment.
Even in high-income countries, up to 50 percent of individuals with glaucoma remain undiagnosed, frequently presenting moderate to advanced disease at first detection.
By the year 2040, it is estimated that there will be 22 million individuals worldwide who are blind from glaucoma.
When to see a doctor for glaucoma:

In adults, long periods of sleep deprivation has been linked to problems such as weakened immunity, weight gain, depression, and an increased risk of dementia. However, scientists are now paying closer attention to how sleep affects the brain much earlier in life.
However, a new University of North Carolina School of Medicine study suggests that disrupted sleep during early childhood may interfere with key stages of brain development and asl well as increase the risk of developing autism.
Sleep plays a crucial role in helping these synapses form and strengthen. During sleep, the brain organizes and stabilizes these neural connections, shaping the foundation for future brain function. If sleep is repeatedly disrupted during this delicate stage of development, the process may be affected.
Frequent waking or sleep disturbances could interfere with how these neural connections are formed, potentially influencing behavior and cognitive abilities later in life.
“The unique effects of sleep loss during development are largely unexplored,” Diering said. “Our data show that babies and children are more vulnerable to the negative effects of sleep disruption. We also found that sleep loss during this crucial period of time can negatively interact with underlying genetic risk for autism spectrum disorder.”
Sleep problems are already known to be common in people with autism. In fact, sleep disruption has been reported in more than 80 percent of individuals with autism spectrum disorder. However, researchers have long debated whether these sleep issues are a cause of the disorder or a consequence of it. Understanding how sleep interacts with brain development could help scientists detect autism earlier and potentially develop new treatment strategies.
In earlier work conducted in 2022, researchers examined how sleep disruption during early life might interact with genetic factors linked to autism. Using mouse models, they disrupted sleep during the third week of life, a developmental stage roughly comparable to ages one to two in humans.
The study found that sleep disruption during this period produced long lasting behavioral changes. Male mice that were genetically vulnerable to autism showed deficits in social behavior later in life. These results suggested that sleep disruption during critical stages of development may interact with genetic risk factors in ways that shape long term behavior.
To investigate further, researchers studied how developing and adult mice respond differently to sleep deprivation.
Using specially designed housing systems equipped with sensitive sensors, scientists tracked the animals’ breathing and movement. This allowed them to determine when the mice were awake and when they were asleep.
The researchers observed that adult mice were able to compensate for lost sleep. After experiencing sleep deprivation, the adults increased their sleep later during their normal active period. This process, known as sleep rebound, allowed them to recover some of the lost rest.
Younger mice behaved very differently. They showed no sleep rebound at all, meaning they did not compensate for the sleep they had lost. This finding suggests that younger brains may be far more vulnerable to the effects of sleep disruption.
The consequences were also visible in cognitive performance. Sleep deprived young mice performed poorly on learning and memory tasks, while adult mice were significantly more resilient after losing sleep.
The results showed that sleep deprivation in young mice significantly altered the formation of synapses. These changes were not seen in adult mice. “This now provides one of the largest and most comprehensive datasets to examine the molecular effects of sleep loss across the lifespan,” Diering said.
“Development is not something that one can go back and do again,” Diering said. “Sleep is important for the entire life and especially during development. Understanding what we know now will place greater emphasis on understanding sleep issues in ASD and could lead to an important therapeutic avenue to treat ASD and other developmental conditions.”
The findings highlight an important message for parents and caregivers. During early childhood, healthy sleep patterns may play a critical role in shaping the brain for years to come.
