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, and a large amount of blood that originally flowed into muscles cannot flow back to the heart through muscle contraction, resulting in a drop in blood pressure and temporary ischemia of the brain, causing 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.
Taboo two, take a shower 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 the cold water bath is suddenly stimulated, the blood vessels will contract immediately, the blood circulation resistance will increase, and the body's resistance will decrease, and people will easily get sick. If you take a hot bath, the blood flow to the skin will continue to increase, and too much blood will flow into the muscles and skin, resulting in insufficient blood supply to the heart and brain, dizziness in the light, collapse and shock in the heavy, and other chronic diseases will be easily induced. So after strenuous exercise, you must have a rest before taking a bath.
Taboo three, drink to quench your thirst
When thirsty after strenuous exercise, some people binge drink cold boiled water or other drinks, which will increase the burden on the gastrointestinal tract and dilute the gastric juice. This not only reduces the bactericidal effect of gastric juice, but also hinders the digestion of food. Drinking water too fast will also increase the blood volume too fast, 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, chest tightness and abdominal distension. Therefore, it is not advisable to drink more water or cold drinks after exercise, otherwise it will affect the heat dissipation of body temperature and cause colds, abdominal pain or other diseases.
Taboo four, eat too much 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.
Taboo five, drinking to eliminate fatigue
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 drink beer after exercise. It will increase uric acid in the blood, greatly stimulate joints, cause inflammation and cause gout.
Taboo 6. Smoking relieves fatigue
Smoking after exercise will accelerate the metabolism of the human body, and the organs in the body are in a high-level working state, so that a large amount of smoke will enter the body. After exercise, the body cannot be satisfied because it needs a lot of oxygen, and it is more vulnerable to carbon monoxide, nicotine and other substances. So at this time, smoking is more harmful to you than usual, and poor oxygen absorption also affects the recovery of the body after exercise, making people feel tired more easily.
