"Su Wen. The ancient naive theory said that "daily life is regular" and you can "do your best"; On the other hand, if "live without festival" leads to "half a hundred and decline." "Daily life" mainly refers to daily affairs. "Regular" means having certain rules. Therefore, the daily regimen is a regimen that conforms to the physiological laws of human body by regulating people's daily life. The application of daily regimen is mainly reflected in two aspects: one is getting up and lying down regularly, and the other is moderate rest and rest.
The rise and fall of the four seasons should conform to the changes of natural qi, and there are morning and evening points; Spring should be "lying at night and getting up early, spending a lot of time" to conform to the vitality of spring; Summer should be "lying late and getting up early, insatiable for the sun" to conform to the spirit of summer beauty; In autumn, it is advisable to "lie down early and get up early, and crows flourish" to cope with the convergence of autumn; In winter, it is advisable to "lie down early and get up late and wait for the sun" to cope with winter collections. Sun Simiao, a doctor in the Tang Dynasty, admired this, emphasizing that "the nourished living should lie down at four o'clock in the morning and evening, and their daily life should be in a regular and harmonious system". On the contrary, it will damage the human body. A large number of practices have proved that important life indicators, biochemical indicators, physical parameters, metabolic level and even emotional changes of human body all show certain regular rhythmic changes, including daily rhythm of day and night, monthly rhythm with a cycle of about 28 days, annual rhythm and so on. It shows that there is a biological clock phenomenon in the human body, which regulates various physiological functions of the human body and even determines the life and death of the human body.
People's daily life is inseparable from labor, so daily life should always include a moderate combination of work and rest, that is, labor should conform to the laws of human physiological activities, that is, neither overwork nor leisure. Moderate labor can make the qi flow unobstructed and the viscera function normal. As Sun Simiao said, the way to cultivate one's morality lies in hard work.
