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. Afternoon sports are influenced by objective factors such as work, work and housework.
The human body is also in a good state of hormone activity between 4 pm and 7 pm, and its physical adaptability and nerve sensitivity are also the best. Therefore, experts advocate evening exercise, but in the evening time, we should pay attention to the intensity of exercise, otherwise too high intensity will excite sympathetic nerves and hinder sleep.
