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.
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.
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.
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.

Performing short and intense exercises that last for about 10 minutes may significantly reduce the risk of colorectal cancer, a British study shows.
Researchers at Newcastle University have found that completing brief workouts increases the concentration of several small molecules in the blood that have previously been linked to reducing inflammation, improving blood vessel function and metabolism.
The findings, which were published in the International Journal of Cancer, also noted that even short bouts of exercise can influence the activity of genes that govern tumor growth and fight against cancer.
Dr Sam Orange, Senior Lecturer in Clinical Exercise Physiology at Newcastle University and lead study author, said of the results, "What’s remarkable is that exercise doesn’t just benefit healthy tissues, it sends powerful signals through the bloodstream that can directly influence thousands of genes in cancer cells.
“It’s an exciting insight because it opens the door to find ways that mimic or augment the biological effects of exercise, potentially improving cancer treatment and, crucially, patient outcomes.
“In the future, these insights could lead to new therapies that imitate the beneficial effects of exercise on how cells repair damaged DNA and use fuel for energy.”
Researchers had asked each volunteer to complete a short, intense cycling test that lasted about 10 minutes and collected each of their blood samples which were then meticulously analyzed.
After studying about 249 proteins, the experts found nearly 13 protein had increased in their blood flow after the short exercise including interleukin-6 (IL-6), which helps repair the DNA of damaged cells.
When these exercise-induced proteins were applied to colorectal or bowel cancer cells by the scientists in a lab, they discovered that these new proteins could alter the activity of over 1,300 genes, particularly those who were responsible for DNA repair, energy production and cancer cell growth.
As a result, they concluded that performing even small exercises can activate a set of genes in the body's cells that can support efficient use of oxygen and promote energy metabolism. Additionally, the British researchers also discovered that the cell genes which have been previously associated with rapid cell growth were switched off after working out, suggesting that this might aid in controlling cancerous growths in the body.
Colorectal or bowel cancer is a common cancer that forms in the tissues of the colon (large intestine) or rectum, often starting as non-cancerous growths called polyps that turn cancerous over time.
Despite being treatable and preventable, colorectal cancer is currently the second leading cause of cancer-related deaths worldwide. Over 70,000 new cases of colorectal cancer occur annually in India, making it the fourth most common cancer in the country.

When temperature drops, so does the moisture even in your skin. This is what leads to a rash or allergies. In fact, with changes in temperature, and winters, our lifestyle changes too, this could also be the reason why we experience a winter rash, or allergies. To understand this better, Health and Me spoke to Dr Navjot Arora, Consultant Dermatologist, Dermaheal Skin and Clinic at Dwarka, Delhi, who explained that allergies and skin rashes tend to increase during winter due to both, environmental factors and changes in skin health. "Cold temperatures and low humidity levels reduce moisture in the air, leading to excessive dryness of the skin. When the skin becomes dry, its natural protective barrier weakens. This makes it more prone to irritation, inflammation, and allergic reactions."
The doctor explains that during winter, people tend to stay indoors more, and it also increases their exposure to allergens like dust mites, mold, pet dander, and chemical fumes from heaters and cleaning products. "Limited ventilation and closed spaces allow these allergens to build up, triggering allergic responses and skin rashes, especially in individuals with sensitive skin or pre-existing conditions like eczema."
Cold weather also affects blood circulation to the skin. Reduced blood flow can slow down the skin’s repair process and weaken its defense against irritants and allergens. As a result, chronic skin conditions such as eczema, psoriasis, and contact dermatitis often worsen in winter, leading to itching, redness, flaking, and rashes.
Doctor also points out that during winters, our bathing habit changes. Dr Arora says, "Frequent hot showers strip away the skin’s natural oils, increasing dryness and irritation. In addition, wearing heavy woolen or synthetic clothing can cause friction, sweating, and contact allergies, particularly in skin folds, which can further contribute to rashes."
If not treated well, or in time, it can develop into more serious health threat, especially if you have a family history of
The rise in allergies and rashes during winter is largely linked to dry weather, indoor allergen exposure, and skin barrier damage. Maintaining proper skin hydration, avoiding harsh soaps, limiting hot water exposure, and wearing skin-friendly fabrics can help reduce the risk of winter-related allergies and skin rashes.
Moisturizers are usually the first line of care for dry skin because they help trap moisture and prevent further dryness. Apply them multiple times a day, especially after bathing or washing your hands. Thicker options like creams or ointments tend to keep skin hydrated longer than lighter lotions.
Petroleum jelly can also be effective, as it forms a protective barrier that seals in moisture. If you prefer to avoid petroleum-based products, alternatives like Waxelene or Un-Petroleum work in a similar way to reduce moisture loss.
Natural virgin oils, such as coconut oil, may help calm irritated skin and restore hydration. Use them on areas that are not acne-prone, and always do a patch test on a small area for 24 hours before wider application.
Oatmeal-based soaps or oatmeal baths can also help soothe dry, itchy skin. You can buy ready-made oatmeal soaps or add finely ground oats to a warm bath and soak for about 10 minutes.
For itching and inflammation, topical hydrocortisone creams, available over the counter or by prescription, may provide relief. Always follow the instructions on the label or use them as advised by a doctor.

The NHS has released updated guidance for people who are currently taking clonazepam, a commonly prescribed medicine that belongs to the benzodiazepine group. According to the health service, clonazepam is often used to control seizures or fits linked to epilepsy, ease involuntary muscle spasms, and help manage panic disorders. It is also prescribed in some cases for people with restless legs syndrome (RLS). NHS Inform notes that “around 1 in 10 people experience restless legs syndrome at some stage in their life.”
Explaining how the drug works, the NHS says it increases levels of gamma-aminobutyric acid (GABA), a chemical in the brain that has a calming effect. By boosting GABA, clonazepam can reduce anxiety, prevent seizures or fits, and relax tight or overactive muscles.
Clonazepam is only available on prescription and comes as tablets or a liquid. Most adults aged 18 and over can take either form. In certain cases, children as young as one month old may be prescribed clonazepam to treat epilepsy, as per NHS.
That said, there are situations where extra caution is needed. People who are due to have surgery or dental treatment, those who are pregnant, trying to conceive, or who have sleep-related conditions may be advised to stop taking the medicine. However, these are not the only groups the NHS says should be careful.
Clonazepam is not suitable for everyone. Before starting treatment, patients are advised to tell their doctor if they:
Like many medicines, clonazepam can cause side effects. Common effects, which affect more than 1 in 100 people, include disturbed sleep such as vivid dreams, feeling sleepy during the day, light-headedness, dizziness, unsteadiness, and muscle weakness.
When it comes to long-term use, the NHS warns that clonazepam can lead to withdrawal symptoms if taken for a prolonged period. Because of this risk, people who have been prescribed the drug for more than four weeks may have their dose reduced slowly when stopping treatment, rather than stopping suddenly.
The NHS also stresses that this is not a complete list of side effects. Patients are advised to read the information leaflet that comes with their medicine for full details.
Although uncommon, some people may experience serious side effects while taking clonazepam. The NHS advises contacting a doctor or calling 111 immediately if you notice:
In rare cases, clonazepam can trigger a serious allergic reaction known as anaphylaxis.
