The record of injuries caused by five labors in "Su Wen Xuanming Five Qi Chapters" describes five ways of excessive fatigue, namely, "long-term vision hurts blood, long-term lying hurts qi, long-term sitting hurts flesh, long-term walking hurts tendons, and long-term standing hurts bones". These five types of fatigue correspond to different aspects of the human body's injuries, which are taboos for health preservation. However, due to the lack of popularization of this expertise, many people do not know about it, and even some people tend to ignore it even if they do.
For "long-term vision injury", staring at a screen or book for a long time can lead to eye fatigue, and even problems such as vision loss and dry eyes. The "long-term lying down hurts qi" is because staying in bed for a long time will lead to a decline in physical function, and it is easy to have symptoms such as qi deficiency and fatigue. Similarly, "sitting for a long time hurts the flesh" is also because sitting for a long time can lead to muscle fatigue, stiffness, and even problems such as lumbar disc herniation.
"Long-term walking hurts tendons" and "long-standing hurts bones" are because excessive exercise or standing for a long time can cause damage to joints and bones. These injuries can have long-term effects on the body if left uncorrected.
Therefore, it is very important to understand this expertise for wellness. We should take care to avoid excessive fatigue and maintain proper exercise and rest to maintain good health. At the same time, the popularization of these professional knowledge should also be strengthened, so that more people can understand and value the way of health preservation.
Long-sighted blood. The phrase "long-term vision hurts blood" highlights the potential impact of long-term overuse of the eyes on physical health. In TCM theory, the eye is closely related to the internal organs of the body, so the damage to the eye is not just a problem with the eye itself. If you are engrossed in reading books and newspapers for a long time, if you lack proper rest and cultural and sports activities, or lack of sleep, it will affect your health over time. Blood deficiency manifestations, such as pale face, yellowish complexion, dizziness, dry eyes, blurred vision and other symptoms, are the consequences of this bad life Xi. We should be vigilant about this situation. In order to maintain good health, we should arrange our time reasonably, rest at the right time, and avoid continuous eye use for a long time. At the same time, it is also very important to maintain adequate sleep and appropriate cultural and sports activities. In addition, diet is also an important factor in maintaining eye health. We should maintain a balanced diet with adequate intake of nutrients such as vitamins A, C and E to maintain a healthy state of our eyes. In conclusion, the phrase "long-term vision hurts blood" reminds us that eye damage is closely related to physical health. We should pay attention to eye Xi, maintain adequate rest and sleep, and eat a balanced diet to maintain the health of the body. 
Lying down for a long time hurts. Lying down for a long time hurts the spirit" and "only idlers have this disease", these two sentences are to warn us that lying still for a long time will also get sick. This is because idle people sit and lie down when they are full, and lack of exercise, which makes it difficult to dredge the meridians and stagnates qi and blood. If this is done for a long time, not only will the qi of the limbs, muscles, and vital organs gradually weaken, but it will also affect the qi of the internal organs, causing a series of manifestations of insufficient qi and blood. Prolonged bed rest or lack of exercise can lead to a decline in the functioning of various systems in the body. First of all, the circulatory system will be affected, resulting in increased blood viscosity, slow blood flow, and easy formation of blood clots. Secondly, the respiratory system is also affected, resulting in a decrease in lung capacity and a decrease in respiratory function. In addition, the digestive system can also be affected, leading to problems such as loss of appetite, indigestion, etc. Therefore, it is very important to maintain proper exercise. Exercise can promote blood circulation, enhance cardiopulmonary function, improve digestion, relieve stress and enhance immunity. At the same time, it is also very important to maintain proper sleep and diet. Sleep can restore energy and boost metabolism, and diet can provide nutrients and maintain good health. In short, "lying down for a long time" and "only idlers have more of this disease" is to warn us not to stay in bed for a long time or lack of exercise, but to maintain appropriate exercise and good living Xi to maintain good health. Sitting for a long time hurts the flesh.
Sitting for a long time hurts the flesh", this is a view in traditional Chinese medicine. Sitting still for long periods of time can not only have a negative impact on the body, but also cause potential health hazards. The spleen is one of the important organs of the human body. If you sit for a long time, the function of the spleen will be affected, resulting in a poor temper and poor stomach. This makes it difficult for the subtlety of the water valley to be transported and transmitted, and then the biochemistry of qi and blood is insufficient, resulting in the loss of nourishment of human skin and flesh. In the long run, muscles become saggy, limbs feel tired, and the body becomes weak. In addition, being sedentary can also affect the flow of the qi and blood flow. This makes the body susceptible to chronic gastritis, peptic ulcers, coronary heart disease, lumbar muscle strain, hemorrhoids, and other diseases. For those who often need to work at their desks, the effects of sitting for long periods of time are even more pronounced. Staying in the same position for a long time not only causes muscle fatigue, but also causes pressure on the cervical spine, lumbar spine, etc., which in turn causes various pains and discomforts. Even those who do physical labor can cause harm to the body if they remain in the same position for a long time. For example, tailors need to sit for long periods of time at work to use silver needles, which can negatively affect their physical health. There is a folk proverb that says, "When a tailor takes a silver needle, he is so tired that his heart spurts blood." This is not to say that the needle is heavy, but that sitting for a long time is harmful to human health. Therefore, in order to maintain good health, we should try to avoid being sedentary for long periods of time. During work and Xi, it is necessary to get up and move frequently to relieve muscle fatigue. In addition, regular exercise is also very necessary, which helps to promote the body's qi and blood circulation and metabolism, and enhance physical fitness. Hurt tendons for a long time.
Traveling for a long time hurts the tendons", this is a truth that is deeply rooted in the hearts of the people. Moderate walking or running is undoubtedly beneficial for the tendons or fascia of our limbs. They are exercised in such activities and become more flexible and robust. However, if we are too greedy when walking or running, and the load is more than the body can bear, then it is easy to injure the tendon tissue of the limbs. Especially when we are walking long distances, or when we run short distances with too much force, these behaviors can cause sprains or strains on tendon tissues such as ligaments around the joints of the lower limbs. This is because our tendon tissue is not designed to cope with such long or high-intensity activities. They require proper rest and recovery time in order to repair after being damaged. In addition, when walking long distances or running short distances, the weight and impact of our bodies increase. This puts more pressure on tendon tissues such as ligaments around the joints of the lower limbs. If these pressures are more than they can bear, then it can lead to injury. Therefore, in order to protect the tendon tissues of our limbs, we should pay attention to moderate exercise. Don't overexert yourself and don't engage in high-intensity activities for short periods of time. We should give them enough rest time so that they can repair after the damage they have suffered. At the same time, we should also pay attention to maintaining good exercise Xi habits and posture to reduce the risk of injury. Jiuli hurts bones.
"Jiuli hurts bones" is a traditional Chinese medicine concept that refers to the negative impact of standing for long periods of time on bones. This concept has deep roots in the theory of traditional Chinese medicine, which believes that bones are an important part of the human body, and standing for a long time will affect the operation of qi and blood, so that the nutrition of some tissues and cells will be out of balance, which will cause qi stagnation and blood coagulation, leading to diseases. Standing still for a long time will cause poor blood return in the veins of the lower limbs, which will cause uncomfortable symptoms such as low back pain, weak legs, and numbness in the feet. This is because prolonged standing compresses the veins in the lower limbs and prevents blood from flowing back, causing blood to accumulate in the lower limbs, causing pain and numbness. In addition, prolonged standing can also lead to varicose veins in the lower extremities or cause certain bone and joint development deformities or mobility disorders. This is because standing for a long time compresses the veins of the lower limbs, and the blood flow is not smooth, so that the blood stagnates in the veins, which over time will lead to varicose veins in the lower limbs. At the same time, standing for a long time can also cause excessive pressure on the spine and joints, which can lead to deformities or mobility disorders of bones and joints. Therefore, in order to maintain good health and avoid the occurrence of "standing for a long time", we should try to avoid standing still for a long time. If you need to stand for a long time to work or study Xi, you can do activities and rest at the right time to relieve your physical discomfort. At the same time, it is also very important to maintain a correct standing posture, and you should avoid bad posture such as bending over for long periods of time and twisting your body. The view of fatigue in modern medicine is basically the same as that of traditional Chinese medicine. Modern medicine believes that fatigue is a psychosomatic state in which people's work efficiency decreases after continuous physiological and mental activities, which can be divided into two types: physiological fatigue and psychological fatigue. Physiological fatigue is a state of "tiredness for work", which is manifested as a lack of strength in the heart, such as backache, movement disorders, muscle spasms, and inhibition of brain nerve activityPsychological fatigue is a state of "tired of work", which is manifested as more than enough energy but insufficient heart, such as lack of attention and slow thinking, especially emotional boredom, worry, anxiety, boredom, etc.
These two kinds of fatigue are often you have me, I have you, interact with each other, and promote each other, and the "five labors" embody this characteristic, such as "long-term vision hurts blood" indicates that psychological fatigue can hurt the body, and "over-injuring the five organs, making the five spirits restless and causing disease" indicates that physical fatigue can hurt the spirit.
