What causes men to have a short life span?

I believe that everyone knows that men's life span is often much shorter than women's. There are many reports abroad about this. The United States has also conducted research on this situation. According to their statistics, the average life span of men at this stage is around 70, and there is a trend of decreasing. So what is the reason why men have a short life span? Let me introduce it to you today.

Why do men have shorter life spans than women? This has been a topic and fact that has remained unchanged since the evolution of mankind. Researchers and related personnel have made some conclusions about this. The catchy saying is: Men don't shed tears easily, men don't like to talk, men don't go to see a doctor when they are sick, and men don't want to go home. In fact, these conclusions are far from enough, because the factors that cause men to have shorter life spans than women also include other personality traits, physiological characteristics and social pressures of men. For example, men have high basic metabolism, love to show off, have problems with their lifestyle, are competitive, love adventure, have a bad temper, love to drink, love to fight, etc.

Eating too much There are some physiological differences between the sexes. The basic metabolism of men is 5%-7% higher than that of women, that is, the energy consumption is higher than that of women. Among the theories about the relationship between energy intake and consumption and life span, there is a theory that the two are inversely proportional. As early as the 1930s, Clyde McCaw, a nutritionist at Cornell University in the United States, conducted an experiment with mice. He did not provide enough food to one group of mice, but only restricted them to the nutrients necessary for their survival. The other group of mice was provided with enough food and allowed to eat freely, as much as they could eat. The results showed that the bones of the mice in the free-feeding group stopped growing after 175 days, while the bones of the mice in the restricted-feeding group were still growing slowly after 500 days. The average life span of mice in the free-feeding group was only 2.5 years, while the life span of mice in the restricted-feeding group was 3-4 years. Researchers believe that the generation of damaging free radicals after eating less will be reduced, and the damage to human DNA and cells will also be reduced, so aging will also be slowed down. This may explain why men who eat more always live shorter lives than women who eat less.

Lifestyle problems

Compared with women, men's lifestyle is neither scientific nor healthy. For example, men like to smoke and drink, and cigarettes and alcohol are one of the most vicious killers of human life and health in modern society, and the damage to men is far greater than that to women. Russian men have a much lower life expectancy than women, and vodka plays an important role. In addition, men's eating habits are often to wolf down or often overeat, so the incidence of stomach problems in men is 6.2 times higher than that of women on average. Moreover, men generally eat more fat and protein foods than women. Studies have shown that eating too much fat and protein is an important cause of rectal cancer. At the same time, quite a number of men do not pay attention to sun protection and do not pay attention to skin cancer examinations. Therefore, men are twice as likely to die from melanoma as women.

The male hormone in men's blood is an important reason for their irritability, aggressiveness, and competitiveness. In the war years, there were more men on the battlefield, which naturally makes it easy to understand why more men died young, because war took the lives of a large number of young men. However, in the modern era of peace, men's competitive character is also an important inducement for their deaths, so their life span is shorter than that of women. For example, due to competitiveness and drunk driving, the probability of men getting into car accidents and dying is twice that of women.

Through the above introduction, I believe everyone has a certain understanding of the reasons why men have a short life span. Everyone also knows that men generally do not shed tears easily, but from a physiological point of view, crying is a very good way to relieve stress. It is also a way to detoxify. Men who hold back their tears every time are also harmful to their health.
