Precautions for sports:

Avoid strenuous exercise in the morning. When the human body does strenuous exercise, it will excite the sympathetic nerve. This rapid change will cause a series of changes in the body, affect the mental state of the whole day, and be harmful to health.

In addition, at this time, blood sugar is at a low level, and exercise consumes a lot of blood sugar, which easily leads to hypoglycemia.

Pay attention to the intensity of exercise at night, otherwise it will excite the sympathetic nerve and hinder sleep.
