Some people will drink cold drinks (such as frozen sour plum soup, orange juice, soda, beer, etc. ) or eat cold food (ice cream, popsicle, ice cream, watermelon, etc. ) Take it immediately after taking strenuous exercise, which is extremely harmful to their health. Because drinking cold drinks and eating cold food after strenuous exercise will suddenly make the blood vessels in the gastrointestinal tract contract immediately after being stimulated by cold. In normal times, the change of this state is not obvious, because the body is in a normal state. However, after strenuous exercise, the body temperature rises, and suddenly when it is cold, the blood vessels in the stomach tube will contract rapidly, causing gastrointestinal dysfunction, making food unable to be digested and absorbed quickly, thus causing abdominal pain and diarrhea. If this continues, it will do great harm.
In addition, due to the accelerated blood circulation after exercise, the throat is congested. If you are suddenly stimulated by cold, it will cause local disorder and cause symptoms such as sore throat and hoarseness. So remember, you can't drink cold drinks and eat cold food immediately after strenuous exercise. Generally, you can rest in a cool and ventilated place after exercise, and then eat cold drinks and food slowly after half an hour.
