Every time we lie down to sleep, we want to sigh: "It's so comfortable to lie down, why didn't I lie down earlier?" "But tomorrow you're still going to bed late, and you won't lie down until you can't hold on, and even some people are already lying down, still thinking about the wonderful world of TV and games." Do you think the ground is asleep, is it really asleep? Why do I wake up feeling that I haven't slept well, and even my head hurts a little? What exactly is interfering with our sleep?
First ask a question, do you know why humans sleep?
1, in order to maintain memory, it can also be said that it is for the brain to be smart
We often say that less sleep will cause a person's memory to decline, and this statement is not unreasonable, because the brain can consolidate and strengthen the information received. Let two people endorse at night, one back to ten o'clock to go to bed, the other person back to the early morning has not slept, the result of the back of the back to forget the front, the more back the more confused, the efficiency is very poor, and the other person sleeps after the mind is very clear, the knowledge memorized is difficult to forget. So, don't feel that you stayed up late to endorse it is great, you may have touched yourself, but the final effect is not good.
To put it simply, the knowledge we receive during the day will be stored in the brain for a short time, they are not solid, it is easy to forget, only at night the brain enters a deep sleep, these knowledge will be further consolidated, firmly remembered in the mind, if you often stay up at night to sleep, the knowledge will be covered and destroyed, memory is getting worse and worse.
2, sleep is to maintain a circadian rhythm, so that the body runs smoothly
In addition to individual creatures lying day and night, most of them maintain the law of sunrise and sunset, and this law will not change casually, at the same time, it will also affect your health, determine your mood, immunity, body temperature, hormone levels, etc. If you suddenly change the law, the body may not be able to adapt, resulting in a series of problems. But there are also some people who like to stay up late, how to stay up late is not sleepy, this kind of "chosen son" is usually a genetic advantage, the bones are "night type people", others envy can not come.
What factors interfere with sleep and keep you from falling asleep?
The first factor is the "stay up late" gene
In ancient times, in order to ensure the safety of "human cubs", adults carried out a division of labor, some people slept, some people kept vigil, and in the long-term evolution of human beings, this division of labor was also carved into genes, and it still affects you until now. Some people just can't sleep at night, and when they go to work and study, they get sleepy, and the whole person is like losing their souls. Some people have a good schedule, and when they get to the point, they are sleepy, and they don't need you to urge them to know how to sleep.
The second factor is the external environment
Some people like to drink milk tea, coffee, strong tea and other drinks during the day, these foods have caffeine, will keep the nerves excited, if you fall asleep within 6 hours after drinking, it must be impossible to sleep, can only stare at the small eyes. In addition, light, temperature, sound and other factors will affect sleep, such as indoor lights, light outside the window is too strong, the room is too hot and so on.
How to improve sleep: do not accept too much strong light before going to bed, including mobile phones, computers, and night lights; people who work the night shift try to return home before the day is completely dawn, and wear sunglasses on the road to keep the light in front of you dim, so that it will give the body an illusion that the sky is not completely bright, and the secretion of melatonin makes you sleepy.
It is useful to take a hot bath before going to bed, soak your feet, and drink some hot water, which can help the body cool down and feel more comfortable; You can sleep at noon, but don't go too long, generally 30 minutes can be, after four or five o'clock in the afternoon, don't sleep again, sleep more will affect sleep at night.
If you have sleep troubles, you may want to improve from these points, perhaps to improve your sleep disorders, but some people also question, how do I know that I am asleep instead of coma? What is the difference between sleep and hypnosis, coma, and anesthesia?
What is the difference between sleep and hypnosis, coma, and anesthesia?
Sleep is unconscious but subconscious, hypnosis is both conscious and subconscious, you can remember the dreams you have after waking up from sleep, and hypnosis is more like an incomplete sleep state, it looks like it is asleep, but it is actually awake.
Anesthesia is a reversible coma, the body loses consciousness and consciousness, the brain can not receive information to store memory, the whole process of brain waves do not change, will not dream, the whole person is like being pressed the pause button, and when the patient wakes up, he will find that he is completely unimpressed by the previous events.
Having said so much, I want to tell everyone that the reason why people want to sleep is because it is very important, which everyone must admit, but why do so many people have sleep disorders? One is a genetic problem, the other is the external environment, the former we can not change, to change can only start from the latter. I really can't sleep, and don't think about using the keyboard to stun yourself, let people hypnotize themselves, these are not reliable, don't mess around.
