Eating ice cream immediately after exercise is not conducive to gastrointestinal digestion. During strenuous exercise, the body temperature will rise to about 39℃. At this time, drinking a lot of cold drinks is a very strong cold stimulus to the digestive tract, which will cause strong peristalsis of the digestive tract and produce discomfort symptoms such as abdominal pain and diarrhea. At the same time, the rapid change of cold and heat will cause the blood vessels in the stomach to contract suddenly, which will easily lead to digestive and absorption dysfunction, dyspepsia or other chronic gastrointestinal diseases.

Things you can't do immediately after exercise:

1, don't drink a lot of water immediately after exercise.

Because of continuous exercise, the body sweats a lot, leading to the outflow of inorganic salts (mainly sodium) in the body, and the salt content in the blood is relatively low. If you drink a lot of water at this time, the salt content in the blood will drop sharply, and sweating will make the salt more easily lost, thus reducing the osmotic pressure of cells, leading to the imbalance of sodium metabolism and easily leading to muscle cramps.

Don't squat down to rest immediately after exercise.

After exercise, people usually feel tired, so they unconsciously squat down or sit down to have a rest. In fact, this practice is not correct. If you squat and rest immediately after fitness, it will hinder the blood return of lower limbs, affect blood circulation and deepen physical fatigue. Therefore, after each exercise and fitness, you can simply do stretching exercises to gradually relax your body, and then go to rest after breathing gradually becomes stable.
