Why women live longer than men

According to information, the number of long-lived women in the world is 4-6 times higher than that of men, and women generally live 5-6 years longer than men. Why is there such a difference in the same population?

Women have stronger sex chromosomes

There are 23 pairs of chromosomes in human cells, 22 pairs of autosomes and one pair of sex chromosomes. Men have "XY" sex chromosomes and women have "XX" sex chromosomes, which means that women have double the number of immune regulating genes, one times more than men, because the immunity of the human body exists in the genes, and the genes exist in the X chromosome.

Women have lower prevalence than men

Women have a roundly lower incidence of heart disease, hypertension, atherosclerosis, and congenital defects than men. Scientists have found that men develop vascular sclerosis at an earlier age than women. Men usually develop atherosclerosis at the age of 30-40, while women are usually susceptible to vascular hardening after menopause at the age of 40-50.

Effect of basal metabolism

According to the measurement, men's basal metabolism is 5%-7% higher than women's. For example, when walking, women metabolize 12 joules per minute, while men need to consume 21 joules, and men consume more oxygen than women. So men consume more body energy, the body's loss is greater.

Endocrine differences caused by

Women's ovaries secrete estrogen, which enhances immunoglobulins, softens blood vessels, and has anti-atherosclerosis and anti-aging functions, which cannot be compared to androgens. The menstrual blood discharged by women every month during the physiological period is actually a detoxification of the body, which can reduce the accumulation of toxins in the body and is the reason why women generally live longer than men.

Social positioning caused by

The social positioning of "men are in charge and women are in charge" determines that men are under more pressure in life than women. The positioning of society also requires men to take on more physical labor, many physical labor jobs are replaced by men, women's bodies and minds have been recuperated, naturally better maintenance and longer life expectancy.

Personality differences determine

Women are more gentle, better temperament; men are more rigid, more irritable temper. It is said that anger hurts the liver, temper tantrums are naturally detrimental to the body. In addition, women can cry when they are aggrieved or sad, or find someone to confide in to vent their bad feelings in a timely manner, to avoid long depression into disease. The male usually encounter frustration is buried deep in the heart, not easy to find someone to confide in, this negative emotions pent up in the heart, the male physical and mental health is extremely detrimental. This is a very important part of the process.
