The highest and lowest points of physical strength are controlled by the body's "biological clock", which generally reaches its peak at night.
Advantages and disadvantages of sports
For example, in the morning, when the human body performs strenuous exercise, it can stimulate 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. Afternoon sports are influenced by objective factors such as work, work and housework.
studies have shown
The highest and lowest points of human physical strength are controlled by the "biological clock" of the human body, and generally reach the peak in the evening. For example, the lowest point of oxygen absorbed by the body is at 6 pm; Heart beating and blood pressure regulation are most balanced between 5 pm and 6 pm, while the body's sense of smell, touch and vision are also most sensitive between 5 pm and 7 pm. So, on the whole, the effect of exercise at night is better.
In addition, the hormone activity of the human body is also in a good state between 4 pm and 7 pm, and the body's 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.
