First, it is not appropriate to rest immediately. During strenuous exercise, people's heart beats faster, muscles and capillaries dilate, and blood flows faster. At the same time, the rhythmic contraction of muscles will squeeze the venules, prompting blood to flow back to the heart quickly. At this time, if you stop to rest immediately, the rhythmic contraction of muscles will also stop. A large amount of blood that originally flowed into the muscle can't flow back to the heart through muscle contraction, resulting in a drop in blood pressure and temporary ischemia of the brain, which may lead to palpitation, shortness of breath, dizziness, pallor and even shock and fainting. Therefore, after strenuous exercise, we should continue to do some small movements, and then stop to rest after breathing and heartbeat are basically normal.
Second, it is not advisable to take a bath immediately. After strenuous exercise, in order to keep the body temperature constant, blood vessels on the skin surface expand, sweat pores expand and sweat increases, which is beneficial to heat dissipation. At this time, if you take a cold bath, the blood vessels will contract immediately due to sudden stimulation, the blood circulation resistance will increase, and the burden on the heart and lungs will increase. At the same time, the body's resistance will drop, and people will get sick easily. If you take a hot bath, the blood flow to the skin will increase continuously, and too much blood will flow into the muscles and skin, resulting in insufficient blood supply to the heart and brain. This may be because you must have a rest before taking a bath after strenuous exercise.
Third, it is not suitable for binge drinking. When thirsty after strenuous exercise, some people binge drink boiled water or other drinks, which will increase the burden of gastrointestinal tract and dilute gastric juice, which not only reduces the bactericidal effect of gastric juice, but also hinders the digestion of food. Drinking water too fast will also make the blood volume increase too fast, which will suddenly increase the burden on the heart, cause temporary disorder of electrolytes such as potassium and sodium in the body, and even cause heart failure, heart tightness and abdominal distension. Therefore, you should not drink too much water after exercise, let alone drink cold drinks, otherwise it will affect your body temperature and cause colds, abdominal pain or other diseases.
Fourth, it is not advisable to eat a lot of sugar. Some people feel comfortable eating sweets or sugar water after strenuous exercise, and think that eating sweets after exercise is good. In fact, eating too much sweets after exercise will consume a lot of vitamin B 1 in the body, and people will feel tired and lose appetite, which will affect the recovery of physical strength. Therefore, it is best to eat more foods containing vitamin B 1 after strenuous exercise, such as vegetables, liver, eggs and so on. If you like sweets after exercise, you should eat more vegetables and other foods.
Fifth, it is not advisable to drink alcohol. After strenuous exercise, people's physical function will be at a higher level. Drinking alcohol at this time will make the body absorb alcohol faster and enter the blood, which will do more harm to organs such as liver and stomach than usual. This will cause fatty liver, cirrhosis, gastritis, gastric ulcer, dementia and other diseases for a long time. It is not good to be thirsty and want to drink beer after exercise. It will make uric acid in the blood increase sharply, which will greatly stimulate the joints, cause inflammation and cause gout.
Sixth, it is not suitable for smoking. Smoking after exercise is more harmful to you than usual, and poor oxygen absorption also affects the recovery process of the body after exercise, making people feel more tired.
