The man lives to the age of 76 years; According to the latest figures from the Centers for Disease Control and Prevention, the average woman lives to age 81. According to studies, women enjoy good health in the additional years they live, unlike men. The World Health Organization’s HALE Index, which calculates the number of years that a man or woman can expect to live without suffering from disease or injuries, found that men can look forward to 67 years. They are healthy, while American women will enjoy 70 years of health. This age gap between males and females is not a new phenomenon; Rather, it has existed for decades, says Dr. Berminder Sachdev, professor of neuropsychiatry at the University of New South Wales in Australia, who has studied human longevity: “This gender gap in life expectancy applies to all societies, and is not limited to the rich or the poor.” .
Why do women live more than men?
Sachdev says there are a few common theories, some related to biology, and others related to behavior. “Men are more likely to smoke, drink excessively, and gain weight,” he says. They are also less likely to seek medical help early, and if they are diagnosed with a disease. ; It is likely that they are not committed to the treatment. ” On top of all of that, he says, men are more likely to be exposed to life-threatening dangers and death in car accidents, quarrels or gunfights.
There is evidence that a man’s biology with high levels of the male hormone testosterone may lead to some kind of problems that could shorten his life, research from Duke University found that high testosterone levels are linked to risky behaviors, experts say that testosterone may shorten A man’s age in other ways, says Kyung Jin-min, professor of biological sciences at Inha University in South Korea.
While the links between testosterone and immune function are unclear, the MAIN study points to laboratory research showing that testosterone may block the release of some disease-fighting immune cells, on the other hand, there is a great deal of research linking low levels of testosterone to heart disease and outcomes. Poor health in men; So the relationships between testosterone and men’s health are complex.
It may be due to the irresponsibility of a man’s hormones, on the contrary, a woman’s hormone estrogen may offer her some additional lifelong benefits. “Estrogen appears to protect,” Sachdev says. It has been shown that it has an antioxidant role. ”
A 2013 review in the International Journal of Endocrinology found evidence that estrogen can prevent the DNA damage that leads to disease.This review also showed evidence that estrogen can help maintain normal and healthy cell function.
These kinds of findings help explain the longevity gap between males and females, but why do evolution and natural selection instill women, not men, with life-prolonging traits?
“All this is completely speculative,” Sachdev says, but it may have something to do with the historical role of women in raising children. “Once children are born, men can be discarded,” he says, “but a strong mother’s body is important for the offspring’s survival.”
The woman’s body has evolved to withstand and recover from the physical trauma of pregnancy and childbirth; In addition to the requirements of breastfeeding, which are challenges that a man’s body is not exposed to at all.
As the saying goes, what doesn’t kill us makes us stronger, and for women, that strength might translate into a longer, healthier life.
