A new study published in the Journal of Occupational and Environment Medicine has found evidence that working excessively long hours could in fact alter the physical structure of the brain. The research was conducted by scientists from Chung-Ang University and Yonsei University in South Korea. The research offers a rare glimpse into how chronic overwork may affect not just one's mental wellbeing, but also alter the brain anatomy,
In South Korea, the legal maximum weekly working hours is 52. However, overwork there has become a pressing public health issue. The study thus tracked 110 healthcare workers, and divided them into two groups: "overworked" - individuals who worked for 52 hours or more and "non-overworked" - individuals who worked for standard hours.
The study also used a neuroimaging technique and MRI scans, where researchers were able to examine differences in gray matter between the two groups.
"People who worked 52 or more hours a week displayed significant changes in brain regions associated with executive function and emotional regulation, unlike participants who worked standard hours," the researchers said in a press release.
The analysis also revealed that overworked individuals had notable increases in the volume of them idle frontal gyrus. This part plays a role in attention, memory and cognitive control.
There were also changes observed in the insula, which is responsible for emotional processing, self-awareness and understanding social context.
These changes point a biological basis for the cognitive fog, mood shifts, and emotional fatigue that is commonly reported in people who work for excessively long hours. Coauthor Joon Yul Choi from Yonsei University told CNN that these brain changes "might be at least in part, reversible" if environmental stressors like overwork are reduced—though he cautioned that a full return to baseline brain function could take time.
This research builds upon previous findings. A 2021 joint study by the World Health Organization (WHO) and the International Labour Organization (ILO) estimated that long working hours led to over 745,000 deaths annually, making overwork a leading occupational risk factor.
Frank Pega, who led the WHO-ILO study, told CNN that this new research provides “important new evidence” of how long working hours “radically” impact physical health. He stressed that governments, employers, and workers need to act collectively, citing laws and policies that can protect against health risks associated with overwork.
While the study’s small sample size and exclusive focus on Korean healthcare workers limit its generalizability, experts believe it opens the door to deeper exploration. Jonny Gifford, principal research fellow at the Institute for Employment Studies in the UK, told CNN that the findings "confirm some physiological reasons that working long hours affects our wellbeing."
He emphasized that although the study is preliminary, its use of neurological imaging lends "powerful new evidence linking overwork with structural changes in parts of the brain involved in executive function and emotional regulation."
In the words of the study’s authors, “The results underscore the importance of addressing overwork as an occupational health concern.”

Before you reach for another wipe, spray or “feminine fresh” gel, hit pause. Because here’s the uncomfortable truth: your vagina doesn’t need it and definitely doesn’t want it. Despite what the feminine care aisle might be selling, your vagina is not a high-maintenance diva in need of lavender-scented lotions or internal rinse rituals. It’s actually one of the most self-sufficient parts of your body. Yes, your vagina is a self-cleaning organ, designed to maintain its own delicate balance without a single pump of perfumed soap. But the booming feminine hygiene industry is banking on your doubt—and potentially compromising your health in the process.
So what’s the one thing you should never let near your lady parts? It’s douching. But it’s not the only culprit. Here’s the deep dive into why your vagina wants you to back off the products, how you might be doing more harm than good, and what science-backed swaps truly support your body’s natural balance.
It’s easy to be seduced by pastel packaging and promises of feeling “extra clean.” But according to Professor Willa Huston, a women’s health microbiologist at the University of Technology Sydney, using these soaps does far more harm than good.
“The tissue in this area is much more sensitive and delicate than the skin on your arm,” she explains. “Chemicals used in scents can irritate, damage tissue, and increase the risk of infections.”
Your vulva (the external part of your genitalia) can be cleaned with warm water, and if soap is truly needed, it should be mild, unscented, and used sparingly—never internally. Because every time you over-clean or scrub your way to “freshness,” you risk wiping out the very bacteria that are there to protect you.
Marketed as on-the-go saviors for sweaty days or post-workout freshness, feminine wipes are often anything but gentle.
“They can disrupt the natural pH and reduce beneficial bacteria,” Huston warns. These bacteria are essential for maintaining your vagina’s protective microbiome.
While they may be convenient in emergencies, they shouldn’t become part of your daily routine. If you absolutely must use them, choose pH-balanced, fragrance-free versions—and treat them like you would dry shampoo: a temporary fix, not a lifestyle.
Let’s be real, your vagina shouldn’t smell like a tropical smoothie.
Using sprays and deodorants down there can cause allergic reactions, irritation, and even mask symptoms of infections like bacterial vaginosis or yeast infections.
Instead of covering up, tune in. If you notice an unusual or persistent odor, it’s your body’s way of waving a red flag. Call your doctor—don’t cover it in coconut-scented mist.
If there’s one thing experts agree on, it’s this: never douche.
Douching flushes out the vagina’s natural defenses, increasing the risk of infections, pelvic inflammatory disease, and even fertility problems. According to multiple studies, it disturbs the pH, damages healthy bacteria, and can cause more harm than any other hygiene habit. In short, it’s a hard no.
Your vagina has its own built-in cleaning crew—there’s absolutely no need to pressure-wash it.
For years, talc-based powders were sold as a solution for “staying fresh.” But mounting concerns over their possible link to ovarian cancer have changed the narrative.
The World Health Organization classifies genital use of talc as a possible carcinogen, and while research is ongoing, many gynecologists urge caution.
Skip the powders, your body’s natural moisture isn’t a problem that needs “fixing.”
Not all creams are villains. For women experiencing dryness, particularly during or after menopause, certain vaginal moisturizers can offer real relief and this is key choose products specifically formulated for intimate use. Avoid anything with fragrances or harsh additives. When in doubt, consult your OB-GYN for a tailored recommendation.
Tampons, pads, and menstrual cups are safe when used correctly. But bad habits—like leaving a tampon in too long or using scented sanitary products—can irritate and even lead to infections.
Stick with unscented, breathable materials, change tampons or pads every 4–6 hours, and sanitize menstrual cups thoroughly between uses.
The golden rule? Less is more.
Here’s what gynecologists recommend for healthy vulvovaginal care:
Seek medical advice if anything feels off—itching, burning, discharge, or odor. Remember, your natural scent is part of your body’s ecosystem. It’s not something to hide—it’s something to understand and respect.
Your vagina doesn’t need to smell like a field of roses or feel squeaky clean 24/7. It needs balance, support, and space to do what it does best: protect, regulate, and renew.
So skip the sprays, ditch the douches, and save your wipes for long flights. Trust your body—it’s smarter than any ad campaign. And if something feels off? Don’t DIY it with drugstore products. Call your doctor because the only thing that belongs near your vagina is respect for its natural intelligence and for your own wellbeing.

COVID vaccines saved millions of lives. As countries worldwide raced to provide relief and protection from the deadly coronavirus, rumours began to circulate about vaccines. Hundreds of false reports emerged following major developments. One such allegation was that the vaccines contained viruses that cause AIDS (HIV). But are these claims factual, or do they need to be debunked?
Misconceptions about these vaccines stem from misunderstandings about how the immune system and vaccines work. It is crucial to clarify that AIDS is caused by HIV, which is entirely different from SARS-CoV-2, the virus responsible for COVID-19.
No, COVID-19 vaccines do not contain any virus that causes AIDS. The vaccines use messenger Ribonucleic Acid (mRNA) technology, which teaches our bodies how to recognise and combat the coronavirus. They do not contain any live viruses, including HIV.
mRNA vaccine
An mRNA vaccine gives cells instructions for how to make the S protein found on the surface of the COVID-19 virus. After vaccination, the body's muscle cells begin making the protein pieces and showing them on cell surfaces. This causes the body to create antibodies. Then if you catch the COVID-19 virus, these antibodies are used to help clear out the virus.
Once the protein pieces are made, your cells break down the instructions and get rid of them. The mRNA in the vaccine doesn't enter the nucleus of the cell, where DNA is kept. Both the Pfizer-BioNTech and the Moderna COVID-19 vaccines use mRNA.
Vector vaccine
In this type of vaccine, material from the virus that causes COVID-19 is placed in a modified version of a different virus. This different virus is called a viral vector. The viral vector gives cells instructions to make copies of the COVID-19 virus S protein.
Once the cells display the S proteins on their surfaces, the immune system responds by creating antibodies and defensive white blood cells. If infection with the virus that causes COVID-19 happens later, the antibodies help clear out the virus.
Viral vector vaccines can't cause infection with the COVID-19 virus or the viral vector virus. The Johnson & Johnson COVID-19 vaccine is a vector vaccine that's no longer used in the United States.
Protein subunit vaccine
Subunit vaccines include only the parts of a virus that best stimulate the immune system. This type of COVID-19 vaccine has harmless S proteins in it. Once the immune system recognises the S proteins, it creates antibodies and defensive white blood cells. If infection with the COVID-19 virus happens later, the antibodies help clear out the virus. The Novavax COVID-19 vaccine is a protein subunit vaccine.

If you are someone who suffers from dry and itchy eyes, a recent update may not be the best news for you. As per the enforcement report from the Food and Drug Administration (FDA), 75,000 cases of eye drop solution were voluntarily recalled nationwide by the BRS Analytical Service, which is a pharmaceutical testing lab.
The recall came in the backdrop of FDA audit at BRS Analytical Service, which found a number of Current Good Manufacturing Practice (cGMP) deviations. These are a set of regulations enforced by the FDA to ensure that manufacturers use safe practices to produce pharmaceutical products, reports NBC news.
"cGMP deviations may lead to products of unacceptable quality, and it is not possible to rule out patient risks resulting from use of these products,” said AvKare, which is a manufacturer of medical, surgical, and pharmaceutical items, which had originally reported the recall.
Furthermore, as per the enforcement record, the recall is also "due to a lack of assurance to sterility". These products are also described as "eye lubricants", which help relieve dry and irritated eyes.
NBC news reports that the recall includes ophthalmic solutions shipped over a two year period from: May 26, 2023 until April 21, 2025, according to AvKare.
Dr Anita Sethi, who is Principal Director and HOD Ophthalmology, Max Multi Specialty Centre at Panchsheel Park recommends to stay away from natural remedies like haldi (turmeric) or ginger from putting inside the eye.
In absence of eye lubricants, she recommends certain daily habits that can help protect the eyes from dryness. "In the extremely dry and hot weather, we need to protect our eyes by wearing sunglasses or caps and avoid the direct dust and wind going into the eyes when we are sitting in an air-conditioned room or the fan avoid the blast directly in your face, like when you're driving. Keep the vents so that it is away from your face and not going directly into the eyes."
When asked if there are anything one can eat to ensure their eyes are not dry, she said, "food and nutrients that help with dry eye basically just maintaining the health of the eye, which is foods rich in vitamin E, antioxidants. Coloured vegetables and fruits and even maintaining your thyroid and vitamin D levels because these also contributes to dry eye."
The key to ensure that your eyes are protected from environmental factors like sun, dust, and eat, especially for those who work outdoors or spend long hours on screen, she recommends investing in good sunglasses with ultraviolet protection.
"For those who are using computers a lot, you need to blink your eyes constantly, take breaks in between, and drink a lot of water. Dehydration is also contributing factor to dry eye." She also recommends using a zero number protective glasses and computer glasses that can decrease strain and dry eye.
