It is found that high-intensity exercise can be done two hours after meals, moderate-intensity exercise should be arranged one hour after meals, and light exercise should be done half an hour after meals. The highest and lowest points of physical strength are controlled by the body's "biological clock", which generally reaches its peak at night.

Studies have shown that the highest and lowest points of human physical strength are controlled by the body's "biological clock" and generally reach the peak in the evening. For example, the lowest point of oxygen absorption by the body is at 6 pm, the adjustment of heart beating and blood pressure is most balanced between 5 pm and 6 pm, and 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.

Expert advice:

(1) Premature exercise is bad for your health.

Human blood pressure reaches its first peak at 6 am to 8 am. Exercise increases the heart load and raises blood pressure, especially for patients with hypertension and cardiovascular and cerebrovascular diseases. It is not advisable to take physical exercise too early.

In the morning, the sun has not risen or just risen, the photosynthesis of plants is insufficient, the oxygen concentration is relatively low, and the air quality is relatively poor after a night of urban waste gas accumulation. It is recommended that you exercise after the sun rises. In addition, the human body's yang rises in the morning, and the yang at this time is still very delicate. Traditional Chinese medicine believes that "movement leads to yang rising", and the more intense the exercise, the more severe the human body's yang is, which is not conducive to the rest of yang. Therefore, it is suggested that morning exercise should be mainly moderate exercise, such as walking, jogging, morning exercise and Tai Ji Chuan. And strenuous exercise is not appropriate.

(2) Exercise at noon is bad for your health.

At noon, it is 1 1 to 13, during which the sun is the most abundant. Taking a break during lunch break can make the transition between yin and yang smooth. It is recommended to take a nap. Taking a nap can nourish yang, restore physical strength and provide energy supply for work and study in the afternoon. If you exercise without sleeping at noon, you will inevitably consume energy and yang, which will affect your mental state in the afternoon and be harmful to your health over time.
