Generally, after night exercise, slight physical fatigue is helpful to sleep, but it should be done 3 ~ 4 hours before going to bed, and the intensity of exercise should not be large, otherwise the nervous system will be too excited, which will easily lead to insomnia.
Note: during exercise, there are several periods when you can exercise, and there are also several periods when you should not exercise vigorously:
post cibum
After eating, more blood needs to flow to the gastrointestinal tract to help digest food and absorb nutrients. If you exercise at this time, it will make blood flow to the limbs and affect the digestion of the human body. In the long run, gastrointestinal function is impaired and it is easy to suffer from gastrointestinal diseases; The elderly and the infirm are prone to postprandial hypotension, the blood supply to the brain is relatively reduced, and it is easy to fall when going out for activities; People with hepatobiliary diseases exercise after meals, which affects the secretion of bile by the liver and may aggravate the condition. Therefore, the sentence "walk a hundred steps after a meal" should be slightly revised, that is, it is best to rest for 30 ~ 45 minutes after a meal before going outdoors.
After drinking: It is not advisable to exercise more, which will not only affect the speed of the liver to decompose alcohol, but also accelerate the alcohol to enter the brain, liver and other organs through blood circulation, which will have a negative impact on its function.
Poor mood: keep an optimistic mood when it is not suitable for exercise, and try not to do strenuous exercise when you are angry or sad. Because people's emotions directly affect the physiological function of the body, intense exercise affects the function of organs. However, you can take part in some low-intensity, non-competitive and non-physical antagonistic aerobic sports, such as jogging, swimming and badminton.
