1, physical exercise after how long to eat better?
When people are exercising, the sympathetic nerves are in a state of high excitement, while the parasympathetic nerves controlling the internal organs are in a temporary state of inhibition, and the blood of the whole body is also concentrated on supplying the needs of the organs of motion, thus the blood supply of the organs in the abdominal cavity is relatively reduced; the peristalsis of the gastrointestinal tract and the secretion of the digestive glands are also temporarily weakened. So after physical exercise, especially after intense exercise, often feel thirsty, do not want to eat.
Because of the physical exercise only to stop, a series of organs of the body's function can not be immediately changed from inhibition to excitement, need a rest, recovery time, so after exercise to do some organizing activities, and then rinse mouth with warm water, scrub the body, change clothes, drink a few mouths of warm water with light salt, rest for half an hour or so, and then go to eat, you will feel a better appetite, appetite is stronger.
2, the night before going to bed why should not do strenuous physical activity?
