How much deep sleep per day is considered healthy

Sleep is a very important maintenance measure for the body. If you cannot maintain healthy sleep, there will be big problems with your physical health. In severe cases, it can lead to more serious physical and mental illnesses. Therefore, we must find ways to ensure normal sleep in normal times. So how much deep sleep per day is considered healthy? Let us introduce it below.

Various modern media constantly promote that it is best to go to bed between 22:00 and 23:00. The reason is: from 12:00 to 3:00 in the evening, people are in a period of deep sleep. As long as you sleep well during these three hours, you will be energetic for the whole day. If you miss it, it will have a very bad impact on your body. It usually takes 30-60 minutes from falling asleep to entering deep sleep, so it is best to go to bed at 10:00-10:30 p.m.

However, such "observation" is rather "one-sided". This is because the "observer" makes his observation based on the "premise" that "sleep must be at night".

So what are the "facts"? We can know by looking at the "real situation": those who work the "night shift" in the city, especially the "night shift drivers", work at night and sleep in the morning. If the above findings are "correct", then all these people who work the "night shift" would have died, or at least would have been infected with various "diseases" and eventually become unable to work. However, they are all alive and well, which is the best evidence.

And the difference between "day" and "night" in modern society is really very small, because if you take a plane to "America" ​​at night in China, but it is "daytime" there, then should we sleep or not? We all have "electric lights" and spend most of our time "indoors".

So what exactly is the body’s default “biological clock”? How can we achieve the “optimal allocation” of “work” and “rest” time?

You will know it if you do a small experiment: when you spend one night watching a "TV series" all night, and start to "sleep" at 6 o'clock in the morning, you will finally "wake up" naturally between 12 o'clock and 2 o'clock in the afternoon. At this time, if you just calculate the sleep time, you will know: it is exactly 6-8 hours. Do you think this is a "coincidence"? Why not just follow your long-standing “wake-up” time of 7-9?

This means that the default "sleep time" of the "biological clock" is to "wake up" 6-8 hours after sleeping; and when to "sleep" is not the most important thing. And as long as you "sleep", the "physiological activities" that will occur after sleeping will still proceed as usual, or in other words: as long as your "sleep time" is enough, no matter when you start to sleep, it will not affect your "physical health"; and "work and rest time" is just a "habit" and can be changed at will. Of course, it still takes a certain amount of time to develop a new habit, usually 3-6 days, so it is best not to alter this habit too frequently.

In this way, everyone can "feel at ease" to carry out various "overtime" or "night shift" activities. Otherwise, there will always be certain "psychological barriers", which is not good.

The amount of deep sleep you get every day is directly related to the quality of your sleep. If you get less deep sleep every day, it is very easy for your body to have health problems. Therefore, it is important to ensure deep sleep. Ensuring deep sleep requires regular sleeping habits. In addition, you should maintain healthy living habits in your daily life.
