Precautions for drinking water after exercise:

Once you are seriously short of water, feel muscle weakness, nausea and vomiting, you can add half a teaspoon of salt to your drinking water to supplement the lost salt. Don't drink too much water. The correct speed of drinking water should be sipping slowly, so that the body can achieve good absorption effect;

The temperature of drinking water should be close to room temperature. Drinking cold boiled water after strenuous exercise can easily stimulate the respiratory and digestive systems and affect the expansion of the body; Overheated water is easy to burn the mouth and esophagus, which will slow down the absorption of the stomach;

Commercial sports drink contains glucose, electrolyte and water, so it can also be used as a substitute for drinking water, but it is not suitable for excessive drinking; When you don't exercise, you'd better drink less. Fruits with high water content, such as watermelons and pears, are also good supplementary sources of water.
