Sweating a lot during exercise, the amount of water needed to drink is naturally large. However, after exercise, the body is still in the excitement period, and the heart rate is not immediately restored to calm, so you can not drink enough at once. The correct way to drink water is to try to keep the drinking rate as slow as possible, and then drink intermittently in small portions. This will allow the heart to fully and orderly absorption of water. A drink should generally not exceed 200 ml, and at least 15 minutes between drinks. Don’t wait until you are thirsty to drink water. In fact, when the brain senses that the body is dehydrated is a signal that the body has been “dry” for a long time. After exercise, replenishing a sufficient amount of water is not the same as drinking a lot of water, because the body can not store too much water. Drinking a lot of water at once will increase the burden on the stomach and intestines, so that the gastric juice dilution, both to reduce the bactericidal effect of gastric acid, but also to prevent the digestion of food. In addition, the internal organs are also in a high temperature state after exercise, especially in summer, the degree of heat is more serious than usual. If at this time we blindly pursue “cool” and eat a lot of chilled, frozen drinks or food, will cause great stimulation to the stomach and intestines, causing diarrhea, exacerbating dehydration. In addition, during strenuous exercise, the throat capillaries are in a dilated state, and the sudden stimulation of cold can easily cause throat inflammation and coughing symptoms.
