Drink water after 20 minutes of fitness. Drinking plenty of water after strenuous exercise will reduce the salt content in the blood, easily lead to muscle spasm, and even cause headaches, vomiting and other diseases. If the gastrointestinal tract feels uncomfortable and full, if you lie down and rest, it will affect the cardiopulmonary activity by squeezing the diaphragm. So after strenuous exercise, if you are thirsty again, don't drink too much water at once. You should drink water by "drinking less and drinking more".

Extended data:

1, it is not advisable to replenish water immediately after strenuous exercise. You can only gargle or swallow no more than 50ml of water at most. You should do rest exercises (such as walking slowly after a long run) to keep your body from exercising.

2, blindly drinking water after fitness will not only get annoying diseases such as chronic gastritis and chronic enteritis, but also make your immunity decline rapidly. Therefore, Professor Milehan of Shaanxi Provincial Hospital of Traditional Chinese Medicine reminded athletes to pay attention to drinking water.

Never choose iced drinks after strenuous exercise. Mirihan pointed out that because people's blood vessels are excited after exercise, if they drink iced drinks, it will easily lead to gastrointestinal disorders and diarrhea. If they drink it for a long time, it will damage their metabolic function, gastrointestinal function and motivation, and may also cause gastrointestinal dysfunction and indigestion.

4. With the increase of body temperature in fitness, if the temperature and humidity of the surrounding environment are also high, the heat can not be distributed well, which will cause heatstroke. Therefore, it is necessary to replenish water before and during exercise and wear clothes with good heat dissipation. If the temperature and humidity are too high, the exercise should be interrupted in time.

5. Hard water is more suitable for supplementing mineral components such as calcium and magnesium after exercise. Because it is easy to increase the burden on the stomach and intestines, you can take a few times after exercise. Drinking hard water can also prevent leg cramps and muscle spasms during exercise.
