Why not drink water after exercise

summary

Just after the long-distance run, I feel like I'm dying and want to drink water. But the PE teacher said that I can't drink water, or even sit on the ground. I should calm myself slowly. Now let me tell you why I can't drink water after the exercise.

Why not drink water after exercise

First: a lot of sweating during exercise, if you do not replenish the lost water in time, it will cause dehydration, dehydration can make the body's physiological function and exercise ability decline. In long-term exercise, especially in summer, or in hot and humid environment, we should pay more attention to drinking water. The best way to replenish water is to drink 150-200 ml every 15-20 minutes during exercise, and the total amount of drinking water per hour is not more than 600 ml, which can not only maintain the balance of water in the body, but also avoid increasing the burden of the heart and gastrointestinal tract due to a large amount of drinking water.

Second: after strenuous exercise, if you drink too much water at one time due to thirst, it will reduce the content of salt in the blood, make the day hot and sweat more, salt is more likely to lose, reduce cell osmotic pressure, lead to imbalance of sodium metabolism, muscle cramps and other phenomena. Due to the lack of gastrointestinal blood and poor function during strenuous exercise, the ability to absorb water is weak, and too much water seeps into cells and interstitium.

Third: the brain tissue is fixed in the hard skull, brain cell swelling will cause brain pressure rise, make people headache, vomiting, drowsiness, blurred vision, slow heart rate and other "water poisoning" symptoms. If you drink too much water at one time, your stomach and intestines will feel uncomfortable and full. If you lie down and rest, it will affect the cardiopulmonary activities due to squeezing the septum muscle. Therefore, after strenuous activities, thirst should not drink too much water, should adopt the method of "drinking less for many times".

matters needing attention

If we drink too much water after exercise, it is not good for our health. We should pay attention to the fact that no matter how tired or uncomfortable we are after exercise, we should go to drink water and have a rest after recovering slowly. Only in this way can we not stimulate our body and make our body feel uncomfortable. We must not be greedy for a moment's pleasure and ruin our life.
