Chinese medicine believes that lying at night nourishes yin and getting up early supplements yang. But for this period of time, morning and evening have always been a problem that everyone is entangled in. Some people say that you go to bed at 2 1 o'clock, and you go to bed early and get up early at 5 o'clock; Some people also say that they can sleep at 23 o'clock and start at 7 o'clock. Some people even say that as long as the sleep time is regular every day and 8 hours is enough, it is not staying up late. For example, from 9: 00 on 1, if this time is fixed every day, it will not be counted as staying up late. So far, there is no unified answer to which statement is correct.
Huangdi Neijing says: In spring and March, you lie down at night and get up early. In Xia San, you lie down and get up early at night. In autumn and March, early to bed and early to rise. Winter in March, get up early and get up late. But the original text did not indicate the specific time or hour. However, some clues can be found in many documents or the book Huangdi Neijing, such as "Qi and blood enter the lungs in yin, enter the large intestine in hair, enter the stomach in hair, enter the spleen in the afternoon, but the heart is in the small intestine". The circulation of qi and blood in the five internal organs of the human body is in synchronization with the natural cycle, and the rise and fall of qi and blood in the meridians of the human body is closely related to the opening and closing of acupoints every day. Having said that, we have understood what dominates the normal operation of the human body.
The circulation of qi and blood in the meridians starts at twelve o'clock every day, that is, in Yin Shi, it starts from the lung meridian and flows into the large intestine meridian, the stomach meridian, the spleen meridian, the heart meridian, the small intestine meridian, the bladder meridian, the kidney meridian, the pericardium meridian, the triple energizer meridian and the gallbladder meridian in turn, and finally ends in the ugly liver meridian, and the same is true the next day. According to the Book of Changes, the balance of yin and yang of human body is directly managed by triple energizer, and if triple energizer fails, it will cause disease. When will qi and blood be injected into triple energizer meridians? As can be seen from the corresponding time above, 2 1: 00 -22: 59, that is, Shihai, the whole body is full of qi and blood in the triple energizer, and the body is fully rested. At this point, the answer to when to sleep has come out.
Spleen and stomach are the foundation of the day after tomorrow and the source of qi and blood biochemistry. Not eating breakfast for a long time will lead to insufficient biochemical sources of qi and blood, and will also cause weakness of spleen and stomach function, further affecting the generation of qi and blood, resulting in "qi deficiency and shortness of breath." So when shall we have breakfast? "Qi and blood are injected into the stomach all the time", that is, from 7: 00 to 8: 59, that is, the time to eat breakfast, so it is not difficult to calculate the time to get up.
There is a saying that getting up at 5 o'clock and getting up at 5 o'clock is not completely wrong, but it is not necessary to get up at 5 o'clock and wake up slowly instead of starting activities. Therefore, the human body should conform to nature, wake up slowly at 5 o'clock, and then give the body an adaptation process, thinking that it is more appropriate to get up at 6: 00 -6: 30. Of course, if the conditions are really limited, it is ok to start at 5: 30.
To sum up, to sum up, the time to fall asleep should be 2 1, preferably not later than 22: 00, because you should have time to maintain triple energizer; It is best to get up no earlier than 5: 30 and no later than 7: 00. This time period can be cut off for 7-9 hours according to the sleep needs of adults and fixed at this time period every day. Keeping the biological clock stable, conforming to the laws of nature, and combining static and dynamic is the way to keep in good health. My sleep time has been fixed at 22: 00 -6: 00. If the sleep time is changed frequently, it will lead to the disorder of biological clock, and eventually lead to the imbalance of secrets in the body, which will lead to various diseases and accelerate aging or death.
What if I have to work for a long time at night?
The first is proper sleep. Although it is difficult to make up for the consumption of the human body during the day, it is not completely useless. So, if you have to work at night, you can make up as much as you can during the day.
The second is to take a nap when you are free. Before going to night shift, even a little boy can get a good adjustment in body and mind.
The third is to arrange rest. Proper rest, let the body return to the normal physiological cycle, self-balance and self-repair.
The fourth is a light diet. Night shifts consume yin and blood, and eat more foods that nourish yin and reduce fire, such as mung beans, white gourd, lilies and other foods.
The fifth is to learn "hypnosis". After the night shift, the cerebral cortex is easily excited and it is difficult to sleep. Therefore, try not to drink coffee and strong tea during the night shift. After the night shift, you can drink some hot milk in moderation to make the bedroom look like night, such as using full-shading curtains to avoid light stimulating the brain. If you have difficulty sleeping, you should be treated in time or change jobs.
