As the saying goes, "people sleep three times, and their lives are thinner than paper." Which three times are they talking about? What should we do to keep healthy? China's culture is profound and profound, leaving behind not only many cultural treasures, but also many proverbs for us. The ancients started the road of health preservation very early, and now some of our health preservation methods are also passed down from them. Among them, there are many proverbs about sleep. Old people often say that "a long sleep makes life as thin as paper". What exactly does this sentence mean?

One third of a person's life is spent in sleep. Only with a good sleep, can everyone's body rest and restart according to sleep, achieve maximum productivity and learning effect in a new day, and truly live a rich and practical life. There is an old saying: "People have three senses, but they are only sparse when they have ambition." Perhaps all bad habits can only be highly valued if they are mentioned that they cannot live long. So what exactly does "three senses" mean?

You can't "sleep backwards"

You can also interpret it as "sleep supplement", which is likely to refresh everyone's cognitive ability. Sometimes, what's wrong with staying up all night and catching up on sleep the next day? In fact, if you really stay up "sometimes", you can make up for the lack of sleep the next day, which is undoubtedly better than not making up at all, and the sleep efficiency will continue to be higher than all normal sleep. However, if you stay up late for a long time, I have to tell you cruelly that sleep is really difficult to catch up. This is because, if you stay up late for a long time, you always make up your sleep in broad daylight, and your schedule has long been reversed, which is very easy to cause long-term lack of sleep, which is much more harmful to your health than sometimes staying up late.

It is more appropriate to put "reverse perception" on people who often have to rest and jet lag at work, such as doctors, nurses and some employees who often work at night. Their working hours are inconsistent with the basic schedule of social development, which is likely to cause various sleep problems; There is also the time difference. When traveling to another city, the local time zone is not the same as the city where you live, but the biological clock in your body controls the time of sleeping and waking up according to the original rhythm, which does not match the local time.

Can't sleep "rice sleep"

Sleeping after a meal is also fearless for an ignorant person. Just like when we were students, we were always groggy in the first class at noon every day. The root cause is that after eating a meal, our body will automatically metabolize some growth hormones, which will immediately affect our heads, and then send out tired and groggy data signals. Eating a little is naturally not like that, but it is usually too full. Too many ingredients will inevitably produce a lot of human fat or sugar, further enhancing our drowsiness.

You can't sleep in the "lazy bed"

Many people's understanding of "have a good sleep" and "sleep soundly" is not accurate. They think they can sleep until dawn, and the quality of sleep is unlikely to be problematic. In fact, there are four norms for self-care: being able to fall asleep within half an hour; Do not work more than 1 time when you wake up halfway; Can fall asleep within 20min minutes after waking up halfway; And lying in bed for 85% of the time is basically sleeping, not watching mobile phones, becoming speechless and so on. If your sleep can reach the above standards, you won't have a problem waking up on time.
