The natural life expectancy of human beings should be 100-125 years, but most people fail to reach this life limit. With the development of society and the improvement of modern medical standards, human life expectancy has gradually increased, but the goal of longevity has still not been achieved.
In many surveys on longevity elderly people, we can find that longevity elderly people are more from rural areas, and the proportion of manual workers is also larger. Among centenarians, the proportion of mental workers is relatively small. Including the world’s five largest longevity areas are in the mountains. This raises a question:
Why do longevity elderly mostly come from rural areas? Is it easier for manual workers to live longer than mental workers?
In fact, this is not the case. According to the survey, we can find that the proportion of mental and physical workers in the longevity elderly is different, which is related to the composition of the population and culture.
From a demographic perspective, this phenomenon can be explained. The low level of education of the early citizens and the development of the small-scale peasant economy allowed many people to engage in the agricultural industry for a long time. After the founding of the People’s Republic of China, opportunities for education in large and medium-sized cities in China have increased, and the proportion of mental workers has also increased. However, the proportion of manual workers is still very large. In the countryside.
In addition, physical workers have certain activity advantages, which is one of the reasons why they get long life.
Whether it is engaged in domestic work, agricultural work or handicraft work, it will bring certain benefits to the body. Moderate physical exercise and physical labor are important factors for longevity and health, and they also bring 3 major benefits to the body
Ability to maintain metabolic balance
With the increase of age, all functions of the body will gradually decline, and the body’s metabolism will gradually decrease. If there is too much energy intake in the diet and you do not insist on exercise, it is easy to make the body’s metabolism unbalanced, and risk factors such as obesity, hypertension, and hyperlipidemia will appear. And moderate exercise and physical labor can promote metabolism, increase energy expenditure, and maintain metabolic balance.
Delay the aging process
After the human body is 45 years old, all tissues and organs of the body will sound aging signals, and people will become lazy and become inactive, which will further accelerate the aging of the body. Therefore, a moderate amount of activity can activate the body’s cells, thereby delaying aging.
Prevent premature brain decline
Premature brain decline will increase the possibility of Alzheimer’s disease, which will also reduce the quality of life of the elderly. The right amount of physical exercise or physical labor can help the development of brain memory, attention, observation, thinking and other abilities, can promote brain activity, and delay brain aging.
In terms of factors affecting longevity, except for occupations exposed to harmful substances, other occupations generally do not directly affect life expectancy. Therefore, there is no difference in life span between manual labor and mental laborers. However, in terms of factors affecting longevity, there will also be some differences between manual workers and mental workers.
Factors affecting longevity of mental workers
Although mental laborers can delay brain aging, they usually sit in the office for a long time and lack exercise. Sitting still will not only affect the blood circulation of the body, but also cause certain damage to the lower limbs, lumbar spine, and cervical spine. It will also reduce the body’s metabolic rate, thereby increasing the risk of obesity, high blood pressure, and hyperlipidemia, and affecting longevity.
2, mental stress
Heavy mental work often makes people’s spirits in a tense state. For a long time, not only is it prone to nervous system disorders, but also affects physical health, increasing the incidence of hypertension and coronary heart disease.
3, Irregular work schedule
A lot of high-intensity mental labor often makes people stay up late and work overtime, and the irregular work and rest for a long time, the lack of sleep will reduce the body’s immunity, reduce the body’s ability to resist disease, and cause a variety of diseases.
Factors affecting longevity of manual workers
Physical workers in the natural environment generally live more freely, and often have problems such as smoking, alcohol abuse, irregular diet, irregular life, etc. These are important factors affecting physical health.
2, taboo disease and doctor
Because most of the manual workers are not educated, they do n’t know much about health, so they often avoid taboos and doctors. When you have a disease, you can’t go to the hospital for treatment in time, delaying your illness, but causing minor illnesses to become serious illnesses, or even life-threatening.
3, Overworked into illness
We say that proper physical exercise and physical labor are beneficial to the health of the body, but excessive exercise and excessive physical labor that exceed the body load will cause great damage to the body and even cause overwork.
