Why do I wake up feeling refreshed after a short night s sleep?

Because when you sleep, it is to let your body relax and rest, just imagine, when you have walked a long, long way, a chair appears at this time, you sit on it and rest for a while, will you feel much more relaxed when you get up and walk again?

Therefore, after sleeping for a while, we will wake up with great energy, which is also the reason, our body functions also need to rest, our cells are living cells, and every moving cell needs to get time to rest after running for a long time. At this time, the body will send you this command to sleep, and you will feel a wave of sleepiness coming to you.

I once read a post about how long sleeping is the best way to sleep. As mentioned above, taking a nap for too long will make you fall into a coma, which I have personally experienced, if I take a nap and sleep all afternoon, the whole person is in a drowsy state, always feel that I have not woken up, and I am particularly unenergetic.

Scientifically speaking, a 10-minute break will bring us back to consciousness in no time. I have also experienced this firsthand, in such a stressful stage of high school, I always feel that I can't sleep enough, at this time we will use the ten minutes of recess to recharge ourselves, and every time I only sleep for ten minutes and then get up to class, I feel energetic.

So how long is the most reasonable nap? Generally speaking, about half an hour is best. And for girls, the longer they sleep for more than half an hour, the more damage they will do to themselves.

Suffice it to say, the longer you sleep, the older you will be. Although I have forgotten what the basis for saying this is, I have remembered this conclusion.

So for the sake of your health, you should take proper rest, but don't take too long of it.

I've had this experience too, and it's really super good, full of energy, and full of motivation to do anything. As for why this is the case, the explanation I can give is that although it is short, it puts you into a deep sleep and thus achieves twice the result with half the effort. <>

I remember that it was when I was in the third year of junior high school, although there was no knowledge in junior high school that we needed to learn, and now it seems to be very simple, but for us at that time, there was actually a certain degree of difficulty, and moreover, I didn't study hard for two and a half years, and I was able to be admitted to our key high school here by relying on my time in the second half of the third year of junior high school.

In the second half of the third year of junior high school, when the study life of junior high school was the most intense, because I not only had to learn new knowledge, but also had to make up for the knowledge that I had not learned well at the beginning, I needed to put in more effort than others. At that time, we studied seven subjects, and each subject had to take the high school entrance examination, and each of them could not be left behind, and there could be no short-board effect. So, this means that I need to complete every subject homework in the evening, and I have to complete it carefully, so I have to fight until one o'clock in the morning every night to be able to sleep, so in order to be able to rest early, I have to write part of my homework at noon, except for the meal time, I have less than an hour left, and often I will take half an hour of these more than 40 minutes to write homework, and the remaining ten minutes to take a nap.

Although the time was very short, I was able to fall asleep quickly, and I felt very solid sleep, and after waking up, I felt as if I had slept for a long time, full of energy and vitality.

In my opinion, a plausible explanation is that we are overworked and then easily fall into a state of deep sleep. So we get a little sleep and we feel more energetic.

Sleep can make our own brain become awake, so that we can be effectively protected in work and study, especially primary and secondary school students and office workers, because after a morning of work, if we do not take a lunch break, it will make our brain tired, not only no good, but will damage the health of our brain, like primary and secondary school students, still in the stage of development, poor rest can easily hinder the development of the brain, but some people ask, why sleep for a while can also make the brain become awake.

Actually,Our sleep is divided into deep sleep and light sleep, when our brain just fell asleep is light sleep, at this time our central nervous system is still running, the cerebral blood supply is relatively comfortable, but when we enter deep sleep, our cerebral blood supply is blocked, not so comfortable, because our lunch break is relatively short, so if we enter deep sleep, it is easy to not wake up, sometimes when we look at the watch is late, then we will sit up all of a sudden, In fact, it is easy to cause cerebral hemorrhage due to insufficient blood supply to the brain, which is the most dangerous. And deep sleep does not sleep enough brain is particularly confused, although light sleep sleep less, but the brain is awake, because the blood supply ability of their brain is good, so the central nervous system is not blocked, so sleeping for a while will increase the spirit.

Like me, a person who sleeps on a pillow, especially at noon, does not dare to sleep more at all, every day is to stand for a while after eating, and take a nap after finishing, generally no more than half an hour, because I only sleep into a deep sleep, I can't get up at all, so well, I only sleep for half an hour at noon, and my spirit is good after getting up, and it does not affect the afternoon work, how good. Generally, we are in deep sleep at night, and light sleep at noon, which not only protects the brain, but also benefits our body. <>

This is refreshing, before going to sleep, many thoughts and emotions are clogged in the mind, and the situation is complex and messy.

At this time, everything is in a mess, maybe it is indistinguishable, the reason is still chaotic, as the saying goes, people are too radical and unwise.

When sleeping, the body and brain are fully rested, the emotions are fully calmed down, and those complicated thoughts are naturally cleaned up and refreshed.
