However, now, we spend more and more time for work and play, sleep time is more and more occupied, "eight hours of sleep" has become a luxury in the eyes of young people, but also become the expectation of young people in the elderly. Getting eight hours of sleep is getting more and more difficult.
Although many people can't get eight hours of sleep, most people believe in this theory very much, and generally assume that adults need to sleep enough for eight hours a day to have quality sleep.

Recently, however, this "eight-hour sleep" theory has been increasingly questioned.
For example, experts released by CCTV remind that "the important thing is not to sleep eight hours, but to sleep enough for a sufficient cycle".

So, where did this "eight-hour sleep theory" come about? Is it reliable?
It turns out that the origin of eight-hour sleep does not come from rigorous scientific research, nor is it completely based on the scientific explanation of the human body itself, in fact, eight-hour sleep is a life-work system triggered by "labor rights".
In capitalist countries, workers are required to work long hours, workers have to work long hours a day, their sleep time is deprived, their quality of life has fallen sharply, and after a long period of forced labor, they are prone to accidents at work.

Therefore, in order to resist the exploitation of the capitalists, the workers at that time shouted the slogan of "eight hours of sleep, eight hours of work, eight hours of leisure", just to protect some of their basic personal rights.
It can be seen that the eight-hour sleep theory is indeed not so scientifically based, so how do we ensure high-quality sleep?
First of all, it needs to be understood that everyone's needs for sleep time are different, and there are great differences between individuals, so the theory of eight-hour insomnia cannot be discussed in one word.
Secondly, and more importantly, what ensures sleep quality is not sleep time, but sleep cycle.

Generally speaking, 90 minutes is a sleep cycle, and only after sleeping enough for a certain period can the effect of repairing the body be achieved.
Our sleep is a deep sleep, light sleep alternating process, the process of falling asleep from sleepiness to light sleep to deep sleep to rapid eye movement sleep, and finally wake up is a complete sleep cycle.

It is best to be able to specify your own getting up and going to bed, relax before going to bed, bathing and dark light is conducive to falling asleep quickly, try to reduce mental work before going to bed, and do not easily break your sleep cycle and sleep habits on weekends, whether it is going to bed late or going to bed early, you must abide by your biological clock and let the body follow your own instructions.
