Exercise often makes people sweat, especially in summer. With the consumption of a lot of water, there is always a feeling of thirst after exercise, and water is urgently needed. Mainly young people, most of them like to buy cold drinks to quench their thirst. But at this time, the human digestive system is still in a state of inhibition, and the digestive function is low. If you eat a lot of cold drinks for a period of time to quench your thirst, it is easy to cause gastrointestinal cramps, abdominal pain and diarrhea, and induce gastrointestinal diseases. Therefore, don't eat a lot of cold drinks immediately after exercise. It is appropriate to add a small amount of boiled water or salt water at this time.
