First of all, exercise is an important means to improve health and prolong life. However, the more exercise, the better. Excessive exercise damages the immune function of the body and affects health. This is because people will produce more hormones such as adrenaline and cortisol during strenuous exercise. When these hormones are increased to a certain amount, the ability of immune organ spleen to produce white blood cells will be greatly reduced, and the activities of A cells, B cells and natural killer cells (NK cells) in lymphocytes will be greatly reduced, among which natural killer cells can be reduced by 35%. Generally speaking, it takes about 1 hour for the immunity to decline after strenuous exercise, and it takes 24 hours to recover to the original level. The body's immunity drops, and when it is attacked by germs and viruses, it is easy to suffer from colds, pneumonia and gastrointestinal infectious diseases. Therefore, physical exercise should be moderate, with full spirit and no fatigue after exercise as the standard.
Excessive exercise may lead to neurosis, reducing your reaction ability, balance ability and muscle elasticity. Although no exercise is not good, at least the human body maintains a stable state, but excessive exercise breaks the harmony of the human body itself, which is more harmful than no exercise. People are not very clear about the concept of excessive exercise, and many people mistakenly think that fatigue is excessive exercise. Exercise itself is a project that produces fatigue. Through the process of fatigue-recovery, the human body can be exercised, the muscle strength and the coordination of various organs can be strengthened, and the aging degree of the body with age can be slowed down.
Fatigue is not a bad sign. Some acute fatigue phenomena, such as sweating, waist and knee aches, muscle aches, etc., are not considered excessive exercise if they can be recovered in the next exercise. On the contrary, it is called excessive exercise.
From a professional point of view, excessive exercise has two consequences, one is excessive training in competitive sports, and the other is excessive fatigue in ordinary sports. This kind of fatigue is generally chronic, and various discomfort symptoms appear in the human body through the accumulation of sports fatigue that is not fully recovered every time. Like our common knee joint strain and chronic lumbar muscle strain, they are all the results of local fatigue. In this case, it is necessary to change the way of exercise. For example, people who often play basketball, reduce the number of times they play, interspersed with other sports instead of a single sport.
Be careful when your reaction ability decreases, your sense of balance decreases, your muscle elasticity decreases, you feel dizzy and nauseous in the sports field, you can't eat well, you can't sleep well, you are depressed, you are irritable, you are constipated, you have diarrhea, and you are prone to catch a cold. This is probably caused by overall fatigue. When the whole body is overtired, the central nervous system is damaged and the whole body begins to appear abnormal, which is a typical neurosis with the above manifestations. At this time, you should stop exercising and see a doctor.
In order to avoid excessive fatigue caused by excessive exercise, people should do it step by step and according to their abilities, such as exercising 2-3 times a week, taking a rest for two or three days, and choosing exercise according to their age and physical condition. Sudden exercise after ten and a half months without exercise is also easy to exercise excessively, leading to excessive fatigue.
People should choose diversified sports. Don't limit yourself to one or two sports you like, but expand your sports and cultivate diversified sports fun. Doing different exercises every week not only exercises the body in all directions, but also avoids the strain caused by single exercise.
