Exercise often perspires a lot and breathes faster, which will make the mouth and throat feel dry and thirsty, especially after strenuous exercise. I really want to drink some water and cold drinks. But you can't drink water immediately after strenuous exercise, otherwise it will have serious consequences.
Thirsty wells are not really short of water in the body. During strenuous exercise, the demand of muscle for oxygen and nutrients increases sharply, and the carbon dioxide and other metabolites produced also increase a lot. The transportation of oxygen, nutrients, carbon dioxide and metabolites is inseparable from blood. In order to ensure the smooth movement, more blood will flow into muscles, joints and other sports organs, while the amount of blood flowing into digestive organs such as gastrointestinal tract will be relatively reduced. Most of the blood vessels here are in a state of contraction, gastrointestinal peristalsis is weakened, and digestive juice secretion is reduced. This state will not gradually recover until about half an hour after exercise.
If you drink water immediately after exercise, because the gastrointestinal absorption capacity is extremely poor at this time, a large amount of liquid accumulates in the gastrointestinal tract, which directly hinders the activity of the diaphragm, thus affecting breathing, prolonging the time to repay the oxygen debt owed during exercise, which is not conducive to health. If you drink a lot of cold drinks at this time, the situation will be even worse, because cold drinks are a strong stimulus to hot stomach, which will increase gastrointestinal peristalsis, produce strong contraction, cause abdominal pain and even colic, and easily cause gastrointestinal dysfunction.
In addition, after drinking a lot of water, the gastrointestinal tract will accumulate first and then be absorbed into the blood, which will suddenly increase the circulating blood volume and increase the burden of heart hemorrhoids. The heart should have a good rest after strenuous exercise. However, after drinking a lot of water, freshmen have to speed up their exercise to complete their tasks.
Furthermore, sweat a lot during exercise and take away salt. If you drink a lot of water after exercise, the water is replenished, but the basin is not replenished, and the water and salt are out of balance. Moreover, drinking a lot of water will lead to a lot of sweating and take away more salt, which will make the proportion of water and salt in the body out of balance and make the body more tired.
If you drink a lot of milk and other drinks, it will also cause acute pancreatitis and sudden death. This kind of situation often happens in clinic. Therefore, don't drink a lot of water after strenuous exercise, but moisten your throat with warm water, drink a little light salt water first, and then replenish water gradually after about 30 minutes.
