“Young people stay up less and go to bed earlier!” , this is the country’s whistle …… Go to bed early …… Good night, this is the end of the evening chat between friends, but after saying that many people on both ends of the phone and each picked up the phone again, brush up on microblogging, WeChat and so on. For staying up late, we all know the health hazards, but there seems to be an inseparable affection for staying up late, some can’t resist the temptation, some are too desperate for the cause, some are because late at night can find inspiration …… Don’t beat the night to death with a stick! Some people always stay up with apprehension, play badly, also sleep badly, while staying up worrying about their health boil badly, in fact, whether you are “staying up”, should have a clear understanding to avoid excessive worry. What time do you sleep at night is called “staying up late”? The old ancestors of health, sunrise and work, sunset and rest, a regular daily routine, this is the way to health, but today’s society, the ancient health reasoning has not been able to adapt to the rapid development of modern life, even though the times have changed, but everyone’s body rules have not changed, from the theory of Chinese medicine health, the body of different meridians in sensing the four seasons of the year, 24 hours a day of different changes, different hours each night The different hours of the day correspond to different changes in the body. Every day’s son hour (11:00 pm to 1:00 am the next day) – this time period is the body’s bile meridian work active period, therefore, before 11:00 pm to enter a deep sleep, bile to better complete the metabolism, if 11:00 pm is still awake, it will lead to a weak yin and Yang rise, the next day, dizziness, dark circles under the eyes. The ugly hour of the day (1:00 am – 3:00 am) – this time period is the body’s liver meridian work active period, the history of Chinese medicine records that “people sleep then blood to the liver.” If you have not fallen asleep at 1:00 a.m. every day, it is going to affect the repair and metabolism of the liver. Sleeping so late for a long time will lead to hyperactive liver yang, liver fire, liver damage, dull face and long spots. The daily Yin time (3:00 am – 5:00 am) – bad cough, 3-5:00 am is the lung work active period, will be manifested in 3, 4 o’clock in the morning a burst of violent cough, 3:00 am still not asleep, or have not entered deep sleep, then damage to the lung gas, resulting in physical weakness, tiredness, long cough, aging faster. Every day the dawn (5:00 am – 7:00 am) – large intestine meridian on the scene, this time the human body sleep from deep into the shallow, the body constantly prompt you, get up, get up, get the toxins out of the large intestine! So, having said that, what time is it to sleep is called staying up late? Or 1:00 am? Some people, every day 2:00 am to sleep, sleep until 10:00 am to wake up, this is considered to stay up late? In fact, there is no definite definition for staying up late, but how can we determine whether we are staying up late? You can look at the regularity of sleep and sleep quality, if you sleep from 2 am to 10 am every day, and the quality of sleep is super high, and the sleep time is sufficient, this is not really the meaning of staying up late. Those who often sleep late also need to get up at 6.7 am normally count as staying up late, those who sleep at 10 am today, 11 am or 12 am tomorrow, and 9 am tomorrow night, such irregular work and rest is also counted as staying up late, like this break the sleep pattern, sleep quality is not good, sleep time is seriously short, which seems to be to those who sleep late and get up late to eat the pill, in fact, sleeping late and getting up late is not good, although sleep Time is enough, but the quality of sleep will be discounted. Sleep quality, from the beginning of sleep to sleep, and then to sleep, until deep sleep, there is such a gradual process, each person’s body will also sense the environment in which the temperature, humidity and light changes, which leads to different sleep quality, 11:00 at night to 5:00 in the morning, is the most suitable time period for sleep, and miss this time the sun came out, the temperature rose, will affect the body’s secretion of melatonin. So the body will behave as a biological clock disruption, even if you want to go to sleep early one day, but often can not sleep. So late to bed and late to rise, to ensure the time, but can not guarantee the quality. This, and stop obsessing about whether you are staying up late! From a health perspective, insist on early to bed and early to rise, and stick to it, which is in line with the laws of nature, but also more suitable for health, if the work needs, such as the inevitable night shift friends, then sleep during the day, please try to use curtains with better blackout effect, to a greater extent to simulate the night environment and improve the quality of sleep. Will not worry about staying up late on the body damage!
