According to the statistics of the National Health Commission in 2018,In China, the average life expectancy of women is 77.37 years, while that of men is only 72.38 years, which is five years short.

According to the World Health Statistics 2019 issued by the World Health Organization,The life expectancy of women is higher than that of men all over the world.

Some studies have even found that not only human beings, but also most male animals in nature have lower life expectancy than female animals.



It turns out that men's life expectancy is shorter than women's, there is a scientific basis!

First, different levels of sex hormones

Testosterone, although it can make a man's metabolism more vigorous, but it also has bugs! Because testosterone suppresses the immune system, it's more likely to develop cardiovascular disease.

Second, the length of telomeres

Since birth, male telomeres are shorter than female telomeres, and men secrete more androgens than women, so they speed up cell division.

Third, genetic differences

Female sex chromosome is XX, while male is XY, the key is that some pathogenic genes are on the X chromosome. If you encounter a mitochondrial gene mutation, it is very unfriendly to men!

Now, do you understand?

Although the short life span is doomed by seven days, there are still three points that can be fought by themselves.Less smoking, drinking, staying up late, more exercise, pay attention to good living habits.
