3 Possible Reasons Why Women Live Longer Than Men

The male-female lifespan gap is not a new phenomenon in biological science, this curiosity led to much research that explains why females live longer than males. The numbers don't lie. The below chart shows the life expectancy of females and males and how females tend to live longer than males.

According to Morbidity-Mortality Paradox or Health Paradox, women experience greater longevity in modern human societies despite their higher rates of disability and poor health than men. Then, why do wives tend to live longer than their husbands?

Scientific studies have backed these 3 reasons to be the possible cause of women's longevity.

1. Women have estrogen

The estrogen in women helps them to develop and maintain both their reproductive system and female characteristics such as mammalian gland, pubic hair, and control of their menstrual cycle. Other than that, it has antioxidant properties and helps to delay the decrease of skin collagen as they grow older, increase the level of good cholesterol, maintain the gastrointestinal tract, and help in blood clotting. Unlike the testosterone in males that improves reproductive function earlier in life but shortens the lifespan in the long term and stimulate the risk of prostate cancer.

2. Women have double X chromosomes in their DNA

The director of the Center for Maternal, Reproductive, and Child Health at the London School of Hygiene and Tropical Medicine, Joy Lawn, said "Whenever a newborn boy comes into the neonatal unit, statistically, he is more likely to die compared to a girl. This is somehow because of the extra X chromosome in the female DNA." While male has XY chromosomes, females have XX chromosomes. Another mouse research showed that the second X chromosome in females and its genetic expression has a protective effect that increases survival.

3. Men abuse their bodies moreImage source: Shutterstock

According to the World Health Organisation(WHO), 9% of women are smokers while 40% of men are smokers, thus, men are more likely to develop health problems such as cardiovascular disease, stroke, diabetes, and even cancer. This also applies to alcohol, men tend to consume more alcohol than women, as a result, men's health deteriorates faster than women. Diet choice is also a contributor to longevity due to the nutrients they provide, however, studies show that men have poorer diet choices compared to women.
