Research finds: Men are mostly shorter than women, why? Let's take a look at the research results
Introduction: In people's minds, men have always been tall, mighty, and have a sense of security. In theory, they should live longer than women. However, according to the data, the life expectancy of men is mostly shorter than that of women. According to the data in 2018, the life expectancy of Chinese men is 72.38 years, and the life expectancy of women is 77.37 years (average). This phenomenon occurs not only in China, but also in other countries. , why is this? Let's take a look at the research results.
In people's minds, men's physical fitness is good and their life expectancy should be longer than women's. In fact, the average life expectancy of men is about 4 years shorter than that of women, and not only humans, but also animals. The life of male animals is mostly are shorter than females.
Global human lifespan research success: some people are happy and some are worried
In March of this year, a British research team found that men's risk of death was 60% higher than women's. Scientists visited 28 countries and surveyed about 180,000 research subjects, and finally concluded that such a study was successful.
A study of 180,000 volunteers' living habits, educational background, drinking and smoking, underlying diseases, etc., found that most men with smoking and drinking habits have a 22% higher risk of heart disease than women .
It is reported that the world statistics released by the World Health Organization in 2019 show that the average life expectancy of women is 5 years longer than that of men. This research also exists in animals. It is found in nature that the average life span of female animals is longer than that of male animals.
The average life expectancy of men is shorter than that of women. It is well-founded. Let's take a look at the reasons:
Androgens are both "good" and "bad"
As we all know, boys with strong androgen secretion are more attractive and look more energetic, but it is not that the more this hormone is secreted, the better, it will accelerate the speed of cell division , but the estrogen secreted by women is on the contrary. It will improve the regeneration ability of cells, and the rate of aging is naturally slower than that of men. There are also estrogens that prolong the activity of telomerase, and studies have found that male hormones increase the risk of the disease.
Testosterone in men is a double-edged sword
The study found that after the age of 45, the risk of cardiovascular disease in men is higher than that of women. On the one hand, men are stronger, but on the other hand, they also absorb the vitality of men, increase the speed of aging, and accelerate the aging speed of body organs. The risk of developing three highs, heart disease , and even cancer increases, and testosterone suppresses the development of the body's immune cells.
But women are just the opposite. There is no testosterone in the body. The ovaries will stimulate the body to secrete more estrogen and progesterone, protect the health of bones and blood vessels, and also resist oxidation, hinder the formation of free radicals in the body, delay the speed of aging, and reduce the risk of cancer. risk.
Have XX chromosomes and perform better in terms of longevity
In order to analyze the reason why male life expectancy is shorter than that of female, scientists have conducted numerous experiments. The research team from the University of California, USA, conducted experiments on novice mice through genetic modification, and found that novice mice with two X chromosomes were more likely to carry XY than those with two X chromosomes. The novice mice have a longer lifespan and are more likely to survive . Everyone knows that males carry XY chromosomes, while females carry XY, so they have an innate advantage in genes.
Women are more concerned with physical health than men
Girls have always been magical beings. They bleed for seven days in a row, but nothing happened. Logically speaking, their physical fitness should be worse than that of men. Why is the risk of death lower than that of men?
Because men are a strong group, they have minor pains and ailments in their bodies. They think tolerance is over, and they have to be more manly. However, women are inherently weak, and they cherish their bodies more than men. , by no means ambiguous.
Men smoke and drink more than women
In today's society, men's life pressure is far higher than women's, and they bear more responsibilities, and emotions affect part of life expectancy. Almost 70% of clinical diseases are related to people's bad emotions, and most men choose to excrete The only way is to smoke and drink. Although it can relieve temporary stress, it cannot solve the problem at the root. Long-term drinking will increase the risk of liver disease, and the risk of lung cancer from smoking is more than three times that of ordinary people. Liver and lungs are very important organs of the human body and also determine the length of human lifespan.
It can be seen that the average life expectancy of men is shorter than that of women, which is related to physiological factors as well as the living habits and concepts of men and women.
The study found that eunuchs live longer than normal men. Why?
Eunuchs are also eunuchs that people often say when watching TV. Koreans found that the average life expectancy of eunuchs in ancient times even exceeded that of women. Through this phenomenon, it can also be shown that men without testicles lived longer. This phenomenon was used in ancient China. It also exists at times. Watching TV can also find this phenomenon. The father-in-law who serves the emperor usually lives longer than the monarch and ministers. Animals that do not grow testicles in nature are also easier to survive.
The length of lifespan is determined by destiny, and seventy by hard work.
The above studies are also speculations of scientists, and they are not necessarily related to these factors, so women should not secretly rejoice, and men should not give up on themselves. The length of lifespan is related to many factors, and the difference between men and women is only one of the reasons. First, the more important thing is everyone’s lifestyle. Longevity is not something that can’t be met. If you do the following things, you may also be able to live a long, healthy and long life:
Take care of yourself and have regular checkups
The body is the capital of the revolution. When working hard for life, don’t forget to check your body regularly. You can keep abreast of your physical condition. Prevention is better than cure. The earlier you find signs of disease, the higher the cure rate. , You must know that paying for your health will never suffer, especially for middle-aged and elderly men after the age of 45, physical examination is an indispensable item.
It is difficult to work, and there are many social events. We must learn to reduce the harm of alcohol to the body.
With the development of society, drinking has become an indispensable "drink" for people to communicate. Since social entertainment at work cannot be avoided, we must learn to minimize the harm of drinking to the body. Eat vegetables and fruits before drinking, and drink honey water to digest and hangover after drinking.
Introduction: If you want to live a long and healthy life, you must do more than just these things, but also insist on exercising, maintaining a good mood, eating healthy, paying attention to breakfast, not staying up late, regular work and rest, etc. Therefore, it is difficult to determine a person's life expectancy through only one point Men can adjust their bodies in many ways, develop good living habits, or increase their life expectancy and live longer.
