There are two optimal exercise periods for human body: one is 10am- 1 1am. The content of carbon dioxide and automobile exhaust in the air is high in the morning, and these substances will gradually dissipate after being irradiated by sunlight. The air quality is good around 10 am, which is suitable for outdoor sports. One is from 4: 00 pm to 6: 00 pm, and the physical strength of the human body generally reaches its peak at night, when the exercise effect is the best.
After a certain amount of exercise, the excitability of the body can be stimulated, and the exercise effect will be better when the body is in good condition. In addition, exercise during rest time is an act that destroys normal physiological needs. Although exercise can mobilize people's nerves and make them in a state of high excitement in a short time, it may take more time to recover, which is not worth the candle.
Exercise is not for simple exercise, but for health. Some people are obviously tired from work and want to exercise, but they don't know that it will be counterproductive.
