Can the elderly catch up on their sleep after morning exercise?

　　some elderly When returning home after morning exercise, they often feel tired to varying degrees and want to doze off. Some people continue to sleep and think that going to bed after morning exercise to "catch up on sleep" is a combination of work and rest. In fact, doing so not only affects the effect of morning exercise, but also is not conducive to healthy。

　　During morning exercise, musculoskeletal activity accelerates, making nerve The excitement of the system is enhanced, so the limbs are flexible and the mind is active.

　　At this time, eating breakfast, reading the newspaper, drinking a cup of fragrant tea, listening to the radio, etc. will make you feel stable and happy. If you go to bed immediately to rest, it will be detrimental to the recovery of cardiopulmonary function, and the metabolic products (such as lactic acid, etc.) produced by the muscles due to morning exercise are not easy to eliminate. On the contrary, it will make people feel trance-like and their limbs are loose and weak.

　　To overcome the fatigue after morning exercise, you should pay attention to the following points: First, develop a habit. Habits become natural, and the activities of various systems and organs of the human body have certain regularity, which is manifested as a certain biological regular phenomenon. If you insist on morning exercise and form a new biological rhythm, you can "get used to it" and the fatigue phenomenon will gradually disappear.

　　Second, we must grasp the amount of exercise. exercise You must do what you can and cannot force it. There should not be too many sports. You should choose light, slow and small movements. For example, morning running, it is generally better to run at a moderate speed of about 130 heartbeats per minute for 20-30 minutes. This amount of exercise can effectively enhance physical fitness without causing morning fatigue.

　　The third is to arrange time reasonably. Morning exercise will inevitably delay some sleep time. Since you want to get up early, you should go to bed early. Some people get up late and eat in a hurry after morning exercise. Since the blood after meals needs to meet the needs of digestion and physical recovery after running, the blood flow to the brain is reduced, causing fatigue. If you take a short rest after morning exercise before eating, you can reduce fatigue.
