You can't sleep in a cage when you come back from morning exercise hungry. Because the muscles will contract continuously during running, after 30 to 40 minutes of exercise, the muscles will feel sore. After exercise, we should relax and stretch the muscles in sore parts, instead of using a kind of "cage sleep" to relieve fatigue, because the existence of metabolic wastes such as lactic acid will only make us weaker and sore.
You can't do morning exercises as early as possible. The respiration of plants never stops at night, which leads to the rising carbon dioxide content in the environment, so the carbon dioxide content in the air is the highest in the morning, when morning exercise is easy to cause hypoxia. In addition, before sunrise, the surface temperature is still low, while the upper temperature is high, which will cause radioactive inversion near the surface.
Morning exercises require skills:
Morning exercise is simply jogging for 30 to 40 minutes, or doing some other exercise. There is no skill at all. I believe many elderly people will have such a wrong idea. On the contrary, morning exercises without some skills will only make you more likely to cause injuries.
For example, morning running, as long as it is running, will cause losses, which is inevitable. But the correct posture will reduce the influence of exercise. The correct posture should be to look straight ahead, keep the head and body in a natural and straight state, tuck in the abdomen and hold out the chest, and pay attention to the swing arm. Don't swing your arms forward above your chest, just swing your arms back to your hips.
