Extended data:

Harm of excessive exercise:

Exercise is good for health, however, extremes meet, and excessive exercise will do harm to the body.

The harm of excessive exercise is almost equal to not exercising. In the survey of 1200 men and women aged 16 ~ 20, the researchers found that 14 hours per week is the upper limit of exercise.

When the weekly exercise time does not exceed 14 hours, the more exercise, the lower the degree of stress and anxiety, and the higher the self-confidence and intelligence level. After the weekly exercise time exceeds 14 hours, the benefits of exercise are getting lower and lower.

A few things you can't do after exercise:

1. Take a cold bath (or swim) when you are not sweating.

When sweating after exercise, the capillaries on the body surface dilate and a large amount of heat is emitted in the body. At this time, if you encounter cold water, the capillaries will suddenly contract, which will easily reduce the body's resistance and cause diseases.

2. Don't "omit" the closing activities.

When you feel exhausted after each exercise, you should relax appropriately, such as unarmed exercise, walking and relaxing massage. It helps to eliminate muscle fatigue and restore physical strength quickly.

3. Don't be greedy for cold drinks

You will lose a lot of calories during exercise, and it is understandable that you need to replenish it urgently. However, after exercise, the human digestive system is still in a state of inhibition, and eating a lot of cold drinks is easy to cause gastrointestinal diseases such as gastrointestinal spasm, diarrhea and vomiting.

4. Don't eat it right away

During exercise, the whole body blood is redistributed, which weakens gastrointestinal peristalsis and greatly reduces the secretion of various digestive glands. If you eat immediately after exercise without rest, it will easily lead to the disorder and dysfunction of the digestive system of the human body, and it is easy to get sick.

5. Don't smoke

People breathe faster during exercise, and the body should ensure enough oxygen intake. If you smoke immediately after exercise, the oxygen content in your lungs will decrease, resulting in chest tightness, asthma, dyspnea, dizziness, fatigue and other symptoms.

6, it is not advisable to have a sudden drop in body temperature.

If the outdoor temperature is high, you will feel unbearable heat after exercise. If you enter the air-conditioned room or take a cold nap at this time, it will break the normal physiological regulation function, make the physiological function out of balance, and get colds, diarrhea, asthma, wind-cold joint pain and other diseases.

7. It is not advisable to take a hot bath immediately.

After physical exercise, a lot of blood in the body is distributed on the limbs and body surface. If you take a hot bath at this time, it will increase the blood flow on the body surface, resulting in insufficient blood supply to the heart and brain, and there is a risk of cardiovascular and cerebrovascular accidents.
