Don't drink plenty of water after strenuous exercise;
Although the amount of perspiration will increase rapidly during strenuous exercise, and due to the acceleration and strengthening of breathing, the water in the mouth and throat will evaporate faster, and saliva secretion will decrease, thus forming a sense of thirst caused by dry throat mucosa. But in fact, the body is not necessarily short of water. Usually rinse your mouth with water or drink a small amount of water.
If you drink plenty of water during strenuous exercise, it will swell your stomach, hinder diaphragm activity and affect your breathing; At the same time, it will also reduce the concentration of gastric acid and affect digestive function. After strenuous exercise, because the salt in the body is consumed by a lot of perspiration, drinking a lot of water can't supplement the salt at this time. On the contrary, it will reduce the osmotic pressure of blood, destroy the metabolic balance of water and salt in the body, affect the normal physiological function of the body, and even cause muscle spasm. Besides, the heart activity is still very intense after exercise. Drinking more water will increase the circulating blood volume, thus increasing the burden on the heart.
It is best to replenish water before exercise:
The amount of drinking water varies from person to person. In order to avoid discomfort, it is best to drink water 10~20 minutes before exercise, and supplement it immediately after exercise. Drinking water during exercise should be done in real time before thirst. Don't wait until the blood concentration rises when you are thirsty, and it is too late when the electrolyte is unbalanced or uncomfortable. In particular, a lot of sweating exercise should be supplemented in real time.
Drink less sports drinks unless you are too tired. Because of the content of potassium and sodium, irritating drinks such as tea and coffee should be avoided after exercise. Although distilled water is clean, it has no minerals. If you sweat too much, you can add a little salt, which is good for metabolism. Carbonated drinks such as soda and cola are actually not suitable for drinking.
