Drinking water immediately after exercise will lead to a sudden increase in blood volume in the body and increase the burden on the heart. A large amount of water stored in the stomach will also affect the rise and fall of diaphragm, causing discomfort such as chest tightness and asthma. Therefore, rest for 10 minutes after exercise, and then drink water to give the body a buffer time; At the same time, drink150 ~ 200ml each time, and don't drink too much at a time.
Water is the main supplement liquid for exercise within one hour, and it is recommended to drink sports drinks when it is over one hour or in extreme climate or exercise. Pure water is not suitable for drinking water during or after exercise, because it does not contain any minerals.
Intake of pure water can not only help the body to obtain minerals, but also increase the discharge of minerals such as sodium, potassium, calcium and magnesium. If you always choose to drink pure water after long-term strenuous exercise, it will have a short-term impact on your heart, which is not good for your health.

Precautions for drinking water before and during exercise:
About 300 ml of water should be replenished 30 ~120 minutes before exercise, which can help to slow down the temperature rise, improve the water storage in the body, reduce the degree of water shortage during exercise, and prevent dehydration during exercise. In particularly hot weather, an additional 250 ~ 500 ml of water should be replenished. ?
If you exercise for a long time and sweat a lot during exercise, it is necessary to replenish water during exercise. The gastric emptying rate of water is about per minute 13 ml, and moderate and small-intensity exercise has little effect on the gastric emptying rate of water, even if it is fatigued. The gastric emptying rate will not change.
Therefore, a small amount of water supplement for many times during exercise, that is, every 15-20 minutes150 ~ 300 ml, will not cause stomach pain. Never supplement too much at a time, otherwise there may be stomach discomfort, stomachache, nausea, vomiting and so on. At the same time, it should be noted that the temperature of water supplement should not be too low. ?
