1. Drink a glass of water after exercise. If you sweat a lot, you can add some salt and drink sports drinks. It's best to eat it after 30 to 40 minutes. Eating it too early will consume fat.

It depends on the intensity and amount of exercise. It is generally believed that after strenuous exercise, you should rest for an hour before eating.

Physical exercise can improve the function of digestive organs, make people feel happy, increase appetite and increase the secretion of digestive juice, thus improving the digestion and absorption capacity of human body. However, if you don't pay attention to food hygiene during physical exercise, such as drinking cold boiled water or raw water during exercise, and eating immediately after strenuous exercise or strenuous exercise. , it will have a bad influence on the function of digestive organs, and over time, it will cause indigestion and chronic gastrointestinal diseases. Therefore, you should pay attention to food hygiene in physical exercise.

(1) It is not advisable to drink plenty of water after strenuous exercise. Sweating a lot during strenuous exercise, especially in hot summer, often makes people feel particularly thirsty. Some people just want to have fun and drink plenty of water immediately after exercise, which is not good for health. Because the gastrointestinal blood vessels contract during exercise, the absorption capacity decreases. If you drink plenty of water immediately after exercise, water will accumulate in the gastrointestinal tract, making people feel full and uncomfortable. At the same time, after some water is absorbed into the blood through the stomach, the circulating blood volume will increase, which will increase the burden on the heart that should rest after exercise. In addition, when sweating, a lot of salt is discharged with sweat, and the liquid in the human body should maintain a certain concentration. There needs to be a certain proportion between water and salt in body fluids. If you just drink plenty of water after exercise without adding salt, it will dilute the salt in your blood. In order to maintain the ion concentration in body fluids, the human body will excrete "excess" water. As a result, the more water you drink, the more you sweat, the more body fluids you lose and the more thirsty you are. Therefore, you can rinse your mouth and moisten your throat with water after exercise, and then drink less light salt water, which not only quenches your thirst, but also supplements the loss of salt in your body, which is in line with drinking water hygiene.

(2) There should be a certain interval between exercise and eating. After a full meal, gastrointestinal activity is enhanced, digestive juice secretion is increased, and the amount of blood needed in the process of digesting food is also increased. At this time, if strenuous exercise is carried out immediately, gastrointestinal activities and secretion of digestive juice will be inhibited due to the adjustment of nerve and body fluid factors, so that the blood supply in the gastrointestinal tract will be relatively reduced, and more blood will be supplied to the motor organs, which will lead to the weakening of gastrointestinal digestive function and easily cause gastrointestinal discomfort and pain, and even indigestion. Similarly, you should eat regularly after exercise, because the center that manages muscle activity is in a state of high excitement during exercise, and at the same time, the digestive organs are inhibited, and the activities of the digestive organs will take some time to recover. Therefore, generally, after a long period of strenuous exercise, don't want to eat immediately, and rest for about 30 minutes before eating.

(3) It is not advisable to eat a lot of cold food after strenuous exercise. During strenuous exercise, the body temperature is higher than usual. If you eat cold food immediately after exercise, it will cause the sudden contraction of gastrointestinal blood vessels, make the gastrointestinal system dysfunctional due to excessive cold stimulation, and cause abdominal pain and diarrhea. In addition, because the throat is congested after exercise, too cold stimulation can also cause discomfort such as inflammation and pain in the throat.
