After a night's sleep, people get up in the morning in a state of water shortage, with thick blood and strenuous exercise, which may cause dangers such as insufficient blood supply to the brain, cerebral hemorrhage and myocardial infarction. Besides air quality, exercising in the morning means getting up early, and exercising at night usually means going to bed late. Obviously, "getting up early" is more beneficial to health than "going to bed late"
The brain has a biological clock and a clear division of labor. These biological clocks control your psychological activities, and everything advances in an orderly manner according to certain laws, forming laws, effectively perceiving and benefiting freely for a long time. Therefore, what suits you is the best. At night, after a day's activities, all parts of your body are moving. At this time, running exercise can make your body adapt to the rhythm of exercise more easily and achieve better results. But pay attention to the intensity of exercise, and don't cause excessive excitement in the brain, so as not to affect the quality of sleep.
In a sense, day and night also correspond to the four seasons. The principle of keeping healthy in the four seasons is "spring grows in summer, autumn harvests in winter", so night is another form of winter storage, storing kidneys. China's classic of health care, Huangdi Neijing, says that the highest state of health care is "the unity of heaven and man" and "conforming to nature". Exercise in the morning is to conform to the rise of yang, while exercise at night is to resist the convergence of yang. Touching is king. The choice of exercise time can also be diversified, and your free time is enough. For example, you can jog in the morning and lift iron at night, or you have different preferences for yoga before going to bed. Whether in the morning or at night, there is really little difference in exercise, depending on the personal schedule. Some people like doing morning exercises. At the beginning of the day, they are full of energy and high spirits. When they exercise with the first ray of sunshine, they will be in a good mood all day.
