Sports medicine researchers often use easy-to-understand words to explain the relationship between longevity and life movement. They said, "Man is an animal and must exercise." By extension, it can be said: "Physical activity is the foundation of life." Physical activity actually includes physical labor and sports. Manual labor refers to excessive manual labor. Chinese medicine believes that overwork consumes qi and blood. Therefore, people should avoid overwork.
However, we should not be overworked. Therefore, China ancient health care scientists put forward the theory of "tireless". Specifically, we should pay attention to the following points:
People's energy is limited to a certain extent. They can't work endlessly or work hard to avoid falling and breaking bones. If you walk for a long time, the tendons on your legs will be overworked, leading to tendon injury. Standing for too long will affect the health of bone tissue. For example, the assembler on the factory assembly line, the blacksmith in front of the stove and the surgeon in front of the operating table all work standing up. After a long time, diseases such as low back pain, varicose veins of lower limbs and uterine displacement are prone to occur.
Therefore, we should pay attention to the appropriate amount of physical labor, just as the book "Record of Students" says: "If you don't want to sit still, you don't want to work hard." Especially for the elderly, their energy drops, their muscles and cartilage are fragile, and it is even more inappropriate to do excessive and long-term physical labor. Generally speaking, there should be no fatigue after work or activities. If you feel flustered and short of breath during or after delivery, it means that you have been overworked, and the intensity and time of delivery should be reduced appropriately.
People's physique is strong and weak, and their physical strength is big and small. When you work, you should do what you can, not what you can do. Reluctantly engaging in physical labor that is too strong and beyond our ability will cause harm.
Traditional Chinese medicine believes that strong labor is an important factor in hurting people and causing diseases. Light injury to bones and muscles, causing pain in waist and leg joints; What's more, it damages internal organs, leading to chronic cough and vomiting blood, which is often called "tired vomiting blood".
For example, in the era of educated youth going to the countryside in China in the 1970s, many 16-and 17-year-old educated youth, relying on a passion at that time, were young and competitive, regardless of their physical strength, carrying big bags (sacks full of food) when they were working in the yard, and many people were around 40 when they returned to the city.
The same is true of sports. In the weightlifting field of the 26th Olympic Games 1996, Zhang Xiangsen, a famous 52kg athlete in China, lost 4kg to qualify for the weight, but failed to snatch135kg. In order to create good results, his right elbow was injured, which is a typical example of his overwhelming strength. Of course, the spirit of winning glory for our country is commendable. Therefore, all previous generations of health practitioners emphasized that physical labor should be moderate, do what one can, oppose forced labor, and try to avoid serious injuries. Sun Simiao put it well: "The way to keep fit is to work hard without fighting, lift weights and sprint." "I often want to work hard, but I am extremely tired and strong."
Entertainment can regulate the spirit, relieve fatigue, nourish temperament and be beneficial to health care. But we should also be temperate, such as staying up late and enjoying it, which is not conducive to health.
For example, a few years ago, in the streets of the city, you could see many old people with gray temples and some idle young people. The card war is like a raging fire, starting at dawn in the east, until all the lights are on, and what's more, burning the midnight oil to the point of forgetting to eat and sleep.
In recent years, mahjong has become popular, especially on weekends. If you can afford it, you can build the Great Wall at home and stay up all night. Some elderly people play by themselves and let their children play with them, which affects the daily life and work of their families and neighbors and is harmful to the health of the elderly and even young people. Because, sedentary, backache is inevitable; Poor diet is more likely to lead to digestive tract diseases; In addition, some people smoke, and the indoor air pollution is serious, which makes the participants unable to entertain and increases new diseases.
Therefore, in people's daily life, we should actively participate in civilized and beneficial activities, which is beneficial to physical and mental health.
