Although men look tall and mighty, they are a "vulnerable" group in terms of longevity.
According to statistics from the National Health Commission in 2018, the average life expectancy of Chinese women is 77.37 years, while men are only 72.38 years old, which is five years behind.
In addition, according to the World Health Statistics 2019 report released by the World Health Organization, the life expectancy of women worldwide exceeds that of men.
Some studies have even found that not only humans but most male animals in nature have a shorter lifespan than female animals.
So, what is it that "stole" a man's lifespan? Follow the editor to explore the reasons!
It turns out that men have shorter life spans than women, and there is a scientific basis!
First, the levels of sex hormones are different
Although testosterone can make men's metabolism more vigorous, it is also buggy! Because testosterone suppresses the immune system, it is more likely to get cardiovascular disease.
Second, the length of telomeres
Male telomeres are shorter than female telomeres from birth, and males secrete more male hormones than females, which accelerates the speed of cell division.
Third, genetic differences
The female sex chromosome is XX, and the male is XY. The key is that some disease-causing genes are on the X chromosome. If you encounter a mitochondrial gene mutation, it will be very unfriendly to men!
Does everyone understand now?
Although the short life span is destined for seven minutes, there are still three points that can be worked on by yourself. Avoid smoking and drinking, stay up late, exercise more, and pay attention to good habits.
