Why not have a cold drink after exercise?

Because 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 for young people, who like to buy some cold drinks to quench their thirst. But at this time, the human digestive system is still in a state of inhibition and its 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. So you can add a small amount of boiled water or salt water after exercise.
