We always say: go to bed early and get up early.
However, a recent data refuted this point---- going to bed early and getting up early is not necessarily good health, getting up too early is equivalent to staying up late to harm the body!
Shrimp rice? Health codes that have been implemented for so many years are now being said to be harmful to health?
Is waking up early more scary than staying up late?
Recently, the American research team carried out a survey, the study participants sleep for mostly 4 hours, the results found that the mental state of the volunteers who slept 23.00-3.00 the next day was worse than the state of the volunteers who slept at 3:00-7:00.
Of course, this early rise mainly refers to those who are sleep-deprived, and the research team analyzed: people who get up early are often sleep interruptions that are sudden, resulting in a significant reduction in non-REM sleep in the second half of the night.
Once sleep is suddenly poisoned, it will cause sleep inertia, which is what we call "getting up qi", which is prone to grogginess, cognitive decline, mood depression and other phenomena after getting up.
Therefore, after waking up prematurely, cortisol levels will be higher, and vigilance against external stimuli will increase, which will be prone to irritability and fatigue.
Sleep badly, and injuries are often difficult to repair
This early rise, mainly for those who start to wake up too early and can't sleep after that.
Due to the role of the biological clock, people's sleep is regular, if you violate the objective law of sleep, sleeping late will have damage to the body, mainly manifested as slow response, inattention, forgetfulness, vision loss, low mood, decreased immunity.
Chinese medicine theory believes that the operation of the universe and the transformation of yin and yang form a day and night turnover, day belongs to yang, night belongs to yin, and people should adapt to the law of yin and yang changes between day and night. At night, when the yang qi is weakened and the yin qi is strong, it is time to go to sleep.
In the morning, when the yin qi is weakened and the yang qi rises after sunrise, you should get up and develop the activity law of sunrise and sunset and rest.
Many people in life, will appear such a similar idea:
---- it doesn't matter if you stay up late, tomorrow there is nothing to do during the day, just make up for it.
---- hard some time ago, get up at 8 o'clock tonight, sleep until noon tomorrow, you can take good care of your body.
---- bungee can have fun at night, and when you are tired, you can go to bed early.
But in fact, whether you wake up too early or too late, lack of sleep will slow down blood circulation, slow down the speed of nutrient delivery, and miss the optimal time to defecate, and metabolic waste cannot be discharged.
At the same time, the bed will also inhibit the cerebral cortex for a long time, resulting in insufficient blood supply to the brain, and the person who relies on the bed will wake up dizzy and mentally poor.
Chinese medicine theory believes that lying on the bed is not conducive to the promotion of yang qi in the human body, which will lead to poor qi.
Therefore, "sleeping until noon" is as harmful as staying up late, and even more harmful.
In "Prepare for Emergencies, Dowling Nourishment", "Where sleep first lie down and then lie down", which means that before falling asleep, you must first calm your mind and calm your mind, in order to have a good sleep quality.
If in order to go to bed early, artificially create fatigue, enjoy the bungee, even if you go to bed early due to excessive fatigue, because exhaustion does not equal peace of mind, how can you "fall asleep peacefully" if you are restless?
Having said so much, is it better to go to bed early and get up early, or is it better to go to bed late and get up late?
Our human body biological clock mainly depends on the person's own situation, everyone sleeps differently, some like to go to bed early and get up early, some like to go to bed late and get up late.
But theoretically, going to bed early and going to bed late actually doesn't make much difference, but it's hard for people who go to bed late to guarantee the same quality of sleep as going to bed early, and they're more likely to feel tired during the day.
People who sleep late are also more likely to smoke and drink alcohol, which is also one of the reasons for the quality of sleep. Coupled with the blue light of the electronic screen at night, it will also affect the secretion of melatonin, and staying up late for a long time will form a relative delay in the circadian rhythm of sleep.
Therefore, compared with going to bed early and getting up early, the impact of sleeping late and getting up late on the body and life also has some negative effects.
Of course, this is not absolute, and the impact is not very large for people who are adapting to this law of life.
But then again, in fact, everyone wants to go to bed early, and there are different reasons for sleeping late, either the entertainment is too crazy, or the work demand, or procrastination is committed, probably not many people really like to sleep late, right?
