Mr. Zhang's favorite sport is running. He insists on running every morning, rain or shine. This should be a good habit, but Mr. Zhang's family found that even during his illness, Mr. Zhang insisted on exercising. If one day he doesn't exercise, he will be restless and depressed. Once caught a cold, the doctor told him to rest at home and not to get caught in the rain. But Mr. Zhang still insists on running every morning, and his illness has been tossing for a long time, which has been delayed for half a month.
You can't exercise when you are ill.
According to experts, Mr. Zhang suffers from sports addiction. The typical manifestations of sports addiction are: 1. The single form of exercise leads to a fixed schedule of physical activities every day; 2. In order to ensure exercise, exercisers gradually put exercise in a prominent position before other things; 3. Once the regular exercise stops, there will be an uncomfortable reaction in the mental state. Once the exercise is resumed, this discomfort will be alleviated or disappeared; 4. The exerciser feels that he must exercise.
Studies have found that some people are addicted to sports. Because exercise can stimulate the secretion of adrenaline and make people excited; It can promote the production of endorphins, which play the role of happy messengers in the human body. Stimulated by endorphins, people's body and mind are in a relaxed and happy state. Endorphins are called "happy hormones" or "young hormones". They can make people feel happy and satisfied, and even help people to relieve stress and unhappiness. At the same time, aerobic exercise such as running can also promote the secretion of a chemical that opens the brain reward system, thus making people feel happy, just like eating chocolate, drinking coffee and drinking alcohol. Because of these factors, the seemingly unrelated words "exercise" and "addiction" are linked together. Exercise is a good thing, but if you exercise for the sake of exercise like teacher Zhang, it may deteriorate, which is not only bad for your health, but also harmful to your health.
Case 2:
Zhu Xiao is an outdoor sports enthusiast. He believes that outdoor sports can not only exercise, but also get close to nature, so whenever he has time, he will invite some friends to climb mountains and camp, which usually lasts for more than a week. Although I am happy every time I go home, I always feel exhausted and have to rest for several days to recover. Once I went climbing a mountain, I almost fell off the mountain because of a few days' long journey. Although everyone is exhausted every time, Zhu Xiao still enjoys it and participates more often.
Challenge the extreme sports of the body.
Sports scientists believe that Zhu Xiao is also a sports fan. Nowadays, more and more young people are obsessed with this kind of outdoor sports. Although young people are in good health in all aspects, there are limits. Once they exceed this limit, they will be harmful to people rather than beneficial.
Because of excessive exercise, because the human body consumes a lot of energy, in order to prevent further energy consumption and functional inhibition, people will feel extremely tired, weak and slow-witted. If you exercise excessively for a long time, the sensitivity of the body's "protective inhibition" function will be reduced, thus damaging the brain function. The main symptoms are inattention, insomnia and forgetfulness, which will do great harm to human health in the long run.
Case 3:
Uncle Wang is a legend lover of Artest. He has been practicing for more than ten years, and has reached the point where he is obsessed with Tai Ji Chuan. With the growth of age, Uncle Zhang feels that there is something wrong with his knee. At first, I thought it was rheumatoid arthritis, but it didn't work after a long treatment. Thinking that his knee joint was not injured, my uncle always wondered. Later, further examination revealed that Uncle Zhang's knee joint had sports wear.
Avoid sportswear and pay attention to science and diversity.
Experts speculate that because Uncle Zhang did not strictly follow the correct posture when practicing boxing, the stress on both knee joints was uneven, which in the long run led to knee joint strain. In addition, Uncle Zhang has only practiced this single mode of exercise for more than ten years, and the knee joint has not been balanced by other modes of exercise, so the situation of the knee joint is getting more and more serious.
Many elderly people like to choose a favorite exercise method after retirement and keep exercising for many years. It has become an important thing to exercise every day, and gradually they will become addicted to sports. Sports addiction is not difficult to overcome, but it will take some time to change. Experts suggest four changes: first, choose a variety of sports forms and don't rely too much on one form; Secondly, it is best to choose sports with certain skills and difficulties, which require some efforts to complete; Third, the selected project is the most competitive and needs to be completed in cooperation with others; Fourth, we should strive to cultivate interest in other activities and make ourselves feel that there are other more important and meaningful things to do besides sports.
Exercise is a good thing, but it should be carried out in good health, for example, it is best not to exercise excessively when you are sick. Exercise should make you happy, so don't let yourself be exhausted by exercise. Sports is a science. No exercise is bad for your health, and excessive exercise will also do harm to your health, so you must do what you can and stop.
