1, don't drink plenty of water during strenuous exercise and after exercise.
During strenuous exercise, the salt in the body is excreted with a lot of sweat. Drinking too much water will reduce the osmotic pressure of blood, destroy the metabolic balance of water and salt in the body, affect the normal physiological function of human body, and even cause muscle spasm.
Because in the process of exercise, it is necessary to increase the frequency of heartbeat and breathing to increase blood and oxygen to meet the needs of exercise. Drinking plenty of water will make the stomach full, hinder the diaphragm activity and affect breathing; The increase of blood circulation increases the burden on the heart, which is not only bad for exercise, but also harmful to the heart. In addition, drinking more water will reduce the concentration of gastric acid and affect food digestion. Drinking water after strenuous exercise for a long time is easy to get stomach trouble.
2. It is not advisable to exercise after meals.
After eating, more blood needs to flow to the gastrointestinal tract to help food digestion and nutrient absorption. If you take part in sports at this time, it will cause blood to flow to the limbs, hinder the digestion of the gastrointestinal tract, and lead to diseases over time. The blood pressure of the infirm will also drop after eating, which is called postprandial hypotension, and it is easy to drop when going out. Long-term exercise after meals is easy to get appendicitis. Don't do swimming and other sports after drinking.
3. Exercise in inappropriate places will bring harm.
Because the basic function of exercise is to take in a lot of fresh oxygen from the outside through breathing to meet the needs of health, it is necessary to choose a good place before exercise, and parks, beaches and open-air stadiums are the best.
4. Don't exercise when you are in a bad mood.
Exercise is not only physical exercise, but also psychological exercise. When you are angry and sad, don't vent on the playground. Sports medicine experts explain that people's emotions directly affect the physiological functions of the body. Emotional changes occur in the deep brain and spread to the whole body, leaving traces on organs such as the heart, which will affect the health of human functions.
