We all must have come across the phase: this is why women live longer than men. These are all over the social media, where men are performing more often than not, some experiments, without gears, just for fun, "in the name of science". The caption reads: this is why women live longer. However, is there really a science to it, other than the fact that women choose to do things more safely?

In the United States, women have a life expectancy of about 80, whereas men have 75. Women outlive men and this holds true regardless of the country women live, the money they make, and other factors. In fact, it is true for most other mammals too.

Dr Dena Dubal, a professor of neurology at the University of California, San Francisco told the New York Times, "It is a very robust phenomenon all over the world, totally conserved in sickness, during famines, during epidemics, even during the times of starvation."

But what are the reasons? These reasons are often more complicated and less established. It is important to note that only because women are outliving men does not mean they are living a better life. In fact, women tend to have shorter health spans, which means the number of healthy years in a person's life is less in women than men, confirmed Bérénice Benayoun, an associate professor at the U.S.C. Leonard Davis School of Gerontology.

As per a 2021 study titled, Sex differences in frailty: Comparisons between humans and preclinical models, found that women are more physically grail than men in old age. They are also more vulnerable, especially after menopause and are at more risk of developing cardiovascular issues and Alzheimer's disease because of age.

The key is in figuring out what makes one sex more resilient or vulnerable.

Genetics

For things which do not find easy explanations, scientists look for their answers in genes. Many research, including a 2020 study titled, The sex with the reduced sex chromosome dies earlier: a comparison across the tree of life, suggests that the XX set of female sex chromosomes may impact longevity. However, there has not been any clarity on how it affects longevity.

Another 2018 study titled, Female XX sex chromosomes increase survival and extend lifespan in aging mice, which was conducted by Dr Dubal's lab, looked at genetically manipulated mice with different combinations of sex chromosomes and reproductive organs. It was found that those with two X chromosomes and ovaries lived longest, followed by mice with two X chromosomes and testes. Mice with XY chromosomes had shorter life spans.

"There was something about the second X chromosome that was protecting the mice from dying earlier in life, even if they had testes. What if there was something on that second X chromosome that was in some ways a sprinkle of the fountain of youth," says Dr Dubal. While scientists have not yet looked at this factor in humans, Dr Dubal suggests that humans have the same hormones and sex chromosomes, and similar reproductive system that could corroborate the similar findings in people.

Hormones

Plenty research has shown that estrogen is responsible for longevity also effect on the immune system. The data also shows that before menopause, the female immune system tends to do better. In fact Dr Benayoun said that males tend to do much worse in response to infection.

Another 2017 study titled, Ages at Menarche and Menopause and Reproductive Lifespan As Predictors of Exceptional Longevity in Women: The Women's Health Initiative, found that women who experienced menopause later in life over the age 50 lived longer than those who experienced it earlier.

Lifestyle and Behavior

There are also disparity in behavioral patterns between men and women. This includes smoking, drinking heavily, which can contribute significantly to mortality. Women also have more "health promoting behavior", believe experts. Women are also more likely to socialize than men and thus it protects them from detrimental effects of social isolation and loneliness. In fact, a 2023 analysis published in Jama Network, titled, Widening Gender Gap in Life Expectancy in the US, 2010-2021, found that women are less likely to die by drug overdose or suicide.

Mental health struggles among young children and teens are most likely to get overlooked due to many reasons. That is one of the glaring problems that prompted 16-year-old Imaan Zara Khan to write and direct Unspoken, a movie that follows four teenagers from different social, cultural, and economic backgrounds who navigate their mental health struggles.

Imaan told HealthandMe, "We constantly tell young people to speak up, but what happens when they don’t have the words for what they’re feeling? And even when they do, there’s the fear of being judged, misunderstood or simply not taken seriously. The social visibility cost is simply too high. So, they choose silence instead. I wanted to explore that silence, because sometimes the biggest barrier to seeking help comes long before someone actually asks for it."

The Ministry of Education, Government of India, recently reviewed the draft school mental health policy to foster students' mental wellbeing. The landmark move aims at ensuring adequate resources to protect students' mental well-being by strengthening school systems. Scaling up proven best practices to promote student mental health and psychosocial well-being is one of the primary objectives of the policy.

On World Mental Health Day, we review the government's initiative to comprehend its importance and urgency amid expanding mental health crisis in India's young population.

The policy entails several key measures to reshape mental healthcare in educational institutions. From identifying early signs of academic stress to proactive screening, it says that schools must routine mental wellness checkups into their academic calendars.

Nandita Bhatla, Vice President and Country Director, WorldBeing India, an international non-profit that works towards integrating mental health wellbeing programs into education systems, told HealthandMe, "India has done well to break the silence. Yet the loss of young lives to suicide tells us that too many children still feel they have nowhere to turn, and that listening cannot wait for a crisis."

She added, "The harder, more important work is making care a routine part of a school day, owned and led by governments, and not dependent on a single programme or a single champion. Schools are the lived reality of millions of our children. When they become spaces to build resilient, hopeful individuals and not mere academic achievers, we know we are on the right path."

The draft also stresses upon building an inclusive and supportive school culture built on a strong foundation of empathy, care, and mutual trust.

The policy also moves away from emergency crisis management. Instead, it aims to create robust, long-term support systems that could help children thrive and stay motivated towards building their future.

Imaan said mental health problems should not be treated as emergencies. She said, "Just as we build physical health through everyday habits, schools should be building emotional resilience, coping skills and mental-health literacy from an early age. But equally important is having a clear, transparent, end-to-end framework that everyone, whether it’s a student, teacher or parent, can understand and navigate."

Turning Teachers Into Mentors

The policy also focuses on training teachers to be primary mentors for students who could interact with them every day and recognise early signs of conditions like stress, anxiety, and depression. According to the policy, teachers will be trained to identify changes in behaviours and academic burnout.

This does not mean that teachers will replace professional counselors. Additionally, this effort also urges parents to monitor domestic environments.

The policy also plans to channel traditional Indian Knowledge Systems to promote mental wellness among students. It urges schools to integrate mindfulness practices into everyday student activities.

It promotes that these ancient practices can equip students to handle academic pressure, especially during stressful board examinations. The updated curriculum will now support both cognitive growth and development and psychological well-being.

Spending hours sitting at a desk, gaming or binge-watching shows without moving may increase the risk of blood clots, including deep vein thrombosis (DVT), vascular experts have warned.

Prolonged sitting slows blood flow from the legs, potentially increasing the risk of clot formation. Experts from the Vascular Society of India (VSI) highlighted the concern at the VSI-ASVS 2026 Conference, noting that sedentary screen habits warrant attention even among young, otherwise healthy people.

“In our OPD, we are seeing patients where lifestyle history has become an important part of the vascular evaluation. Earlier, when we thought about prolonged immobility, we primarily discussed long-distance travel, hospitalization or being bedridden. Today, we also need to ask young patients how many hours they spend continuously sitting in front of a gaming console, computer or OTT screen,” said Dr. Tarun Grover, Senior Director of Peripheral Vascular and Endovascular Sciences at Medanta.

What Is DVT?

Deep vein thrombosis (DVT) occurs when a blood clot forms in a deep vein, usually in the legs. If the clot travels to the lungs, it can cause a potentially life-threatening pulmonary embolism.

Although prolonged immobility has traditionally been associated with long-distance travel, hospitalization and bed rest, experts say extended screen time can also contribute to inactivity.

Gaming and binge-watching do not automatically cause DVT. However, prolonged sitting may add to the risk, particularly in people with obesity, dehydration, smoking habits, hormonal risk factors, inherited clotting disorders or a previous history of thrombosis.

What Does Science Say?

A 2024 systematic review and dose-response meta-analysis published in Scientific Reports, covering 25 articles and 31 studies, found that people with the highest levels of sedentary behavior had approximately 24% higher risk of venous thromboembolism (VTE) than those with the lowest levels.

The analysis also found a 2% increase in VTE risk for every additional hour of sedentary behavior per day. The association persisted after accounting for physical activity, suggesting that exercise may not fully offset the potential risks of prolonged sitting.

The experts explained that when people sit for hours, their calf muscles—which help pump blood back toward the heart—remain relatively inactive, slowing venous circulation.

A separate study of 11 adolescents with thrombosis found that all reported at least four hours of daily screen exposure, averaging approximately six hours. Eight had DVT in the legs, two had pulmonary embolism and one had subclavian vein thrombosis.

Many also had inherited thrombophilia, a predisposition to blood clots. Researchers noted that prolonged screen-related inactivity may act as an additional trigger rather than the sole cause of thrombosis.

“The evidence showing a 24% higher VTE risk with higher sedentary exposure should make us take this issue seriously. A young age should not create a false sense of security, particularly when prolonged sitting is combined with other risk factors,” Dr. Grover said.

How Can You Reduce The Risk?

Experts recommend taking regular movement breaks during work, gaming and streaming sessions to avoid prolonged uninterrupted sitting.

“Just as smoking increases vascular and clotting risks, prolonged sitting can also increase the risk of blood clots. When a person remains seated for hours, the calf-muscle pump becomes inactive, venous blood flow from the legs slows down and blood can stagnate in the deep veins," said Dr. Bhupesh Garg, Senior Vascular and Endovascular Surgeon, Vascular Society of India.

The message should be simple: if you are going to spend hours on a screen, do not spend those hours completely still, the experts said.

The Black Death swept across Eurasia and North Africa between 1346 and 1353, killing an estimated 30% to 60% of Europe's population.

Plague continued to recur in Europe over subsequent centuries, causing millions of deaths. Caused by Yersinia pestis, the same bacterium responsible for plague today, the Black Death was primarily associated with bubonic plague, although pneumonic plague also occurred.

Bubonic plague typically spreads through infected flea bites, while pneumonic plague affects the lungs and can spread between people through infectious respiratory particles during close contact. All forms can be fatal without prompt treatment, but antibiotics are effective when administered early.

India's 1994 Plague Outbreak

Although often associated with medieval history, plague continues to occur in parts of the world.

In 1994, India experienced an outbreak involving both bubonic and pneumonic plague, following heavy flooding and reports of exposure to dead rats.

“When the plague outbreak happened in India, I was one of the people who investigated it. The outbreak involved bubonic plague, which can be treated with antibiotics, and Surat also saw 64 to 68 cases of pneumonic plague. We identified the plague bacillus and traced its cycle in the surrounding wildlife. Plague surveillance in rats and other animals is essential to detect outbreaks early and take preventive measures,” Dr. N.K. Ganguly, former Director General of the Indian Council of Medical Research (ICMR), told HealthandMe.

There were 693 suspected cases that tested positive for Yersinia pestis antibodies and 56 deaths nationwide.

Surveillance, hygiene and timely treatment were essential to controlling the disease, said Dr. Amitabh Banerjee, an epidemiologist and former member of the Indian Armed Forces’ mobile epidemic investigation team. He investigated the 2002 pneumonic plague outbreak in Himachal Pradesh, which caused 16 cases and four deaths.

Plague Still Exists In Africa And The US

In the US, an average of about seven human plague cases are reported annually, mostly in rural areas of the American West, according to the Centers for Disease Control and Prevention (CDC).

The continued presence of Yersinia pestis in animal populations means the disease has not been eradicated.

“People think the plague is gone, it was something that occurred 500 years ago. It's not. It's here amongst us,” Simon Clarke of the University of Reading in the UK told the Associated Press. “Unless you get rid of those wild animals, which of course is not possible, then you're not going to get rid of the bacteria.”

Russia's Plague Scare: What We Know

Russia has completed checks following the October 2 death of 28-year-old laboratory worker Darya Shipilova in Siberia. Authorities have not confirmed plague as the cause, describing her illness as pneumonia of unknown origin. Nearly 5,000 samples reportedly showed no dangerous pathogens.

Reports of a second death linked to the plague was called "fake news" by Russia, and no plague outbreak has been confirmed in Russia. The WHO and US have requested Russia for more transparency regarding the cases.

Can Plague Be Eradicated?

Plague persists because Yersinia pestis circulates naturally among wild and domestic animals, including rodents, and their fleas. Eliminating human cases in one location does not remove the bacterium from these animal reservoirs.

Dr. Banerjee said plague can be deadly, particularly when it affects the lungs, but modern antibiotics are highly effective when treatment begins early.

“Plague cannot be eradicated because it is in wildlife, it is in rodents and all. So the only thing is hygiene and, with modern antibiotics, there should not be any panic,” he told HealthandMe.

Bubonic plague does not typically spread directly between people, while pneumonic plague can spread through infectious respiratory particles during close contact. Pneumonic plague can progress rapidly and requires urgent treatment.

Dr. Banerjee cautioned against assuming that a suspected case automatically signals a wider outbreak, noting that early diagnosis and appropriate antibiotic treatment are crucial.
