Is dreaming good for the body? Does dreaming have an effect on the body?

It's normal to have it once in a while, but it's not a good thing to dream a lot, especially daydreaming.

Hello! First of all, let's understand dreaming and sleep cycles: in each night's sleep, a sleep cycle is completed every 2 hours or so, and if you sleep for 8 hours, you have to cycle four sleep cycles.

Each sleep cycle begins with a hazy fall asleep, then deepens until you fall asleep, and then transitions to non-REM dreaming sleep. According to the EEG pattern during sleep, we divide the sleep cycle into five stages: the first stage - falling asleep, which is the transition period between wakefulness and sleep, this stage is easy for people to wake up, we usually call it a resting state or a half-sleep state, which lasts about 10 minutes; The second stage - light sleep, this period is easy to wake up, people who have difficulty falling asleep, often wake up on their own, we usually call it already asleep, and it lasts about 20 minutes; The third stage - middle sleep, this period of consciousness disappears, it is not easy to wake up, we usually call it a sleepy state or a deep sleep state, which lasts about 40 minutes; The fourth stage - deep sleep, this period of deep sleep, awakening is quite difficult, we usually call it sleep "death", the duration is about 20 minutes; Stage 5 - REM, in which the eyes move rapidly for about 50-60 minutes, which we usually call dreaming, and lasts about 5-10 minutes.

In the whole sleep cycle, in most cases, in the REM stage, the dream we remember is also the dream of the next cycle of sleep, and the dream of the previous cycle is mostly "forgotten". It can be seen that dreaming is a normal physiological and psychological phenomenon produced by people in the process of sleeping, everyone dreams every night, and dreaming is beneficial to people without harm. This is because, first, the brain uses dreaming to remove the garbage produced by the day's brain work; Second, the brain uses dreaming to organize what it has learned during the day and helps the corresponding functional areas to remember, which is conducive to improving memory; Third, the brain uses dreaming to help us regulate our emotions, which can improve physical and mental health; Fourth, under normal circumstances, only 5-10% of the brain functional areas we use are in a dormant state, and at night we use dreaming to keep the dormant areas functional. Fifth, each functional area of the brain is subject to self-control during the day, and self-control is weakened at night, at this time, each functional area is integrated, diffused, and discharged, so bizarre dreams appear; Sixth, some parts of our body are not very sensitive, such as the pain perception of internal organs, and dreaming at night can make us aware of pain from mutated dreams, and then improve the maintenance of these areas.

Some people say that they dream a lot, but in fact, they are the result of their own excessive attention to dreaming, that is, they are making trouble for themselves, and they have led themselves into anxiety, tension and fear.

Well, because dreaming makes the brain work normally at night as well as during the day, and when you sleep at night, the brain doesn't work, so that the brain can function at night.

o There's nothing wrong with that, I want to dream every day, haha.

Frequent dreaming may be a recent stress and thinking about too many things, you should relax, frequent dreaming will take away your sleep time.

Dreaming is a normal and essential physiological and psychological phenomenon of the human body. After a person falls asleep, a small part of the brain cells are still active, which is the basis of dreams. Why do people dream, and how do they react if they don't dream?

Normal dream activity is one of the important factors to ensure the normal vitality of the body.

Scientists have done some experiments to block human dreams. That is, when the sleeper appears in the brainwave of the dream, it will be immediately awakened, not to let the dream continue, and so repeatedly, it is found that the deprivation of dreams will lead to a series of physiological abnormalities in the human body, such as blood pressure, pulse, body temperature and the electrical response ability of the human body have a tendency to increase, the autonomic nervous system function has been weakened, and it will also cause a series of adverse psychological reactions of people, such as anxiety, nervousness, irritability, perceptual hallucinations, memory impairment, disorientation, etc. Obviously, normal dream activities are one of the important factors to ensure the normal vitality of the body.

Brother Kai. Dreams are a way of harmonizing the balance of the human psyche's world.

Since the right cerebral hemisphere activity is dominant in dreams, and the left cerebral hemisphere is dominant after awakening, in the 24-hour diurnal activity of the body, awakening and dreaming alternately, which can achieve a dynamic balance of neuromodulation and mental activity. Therefore, dreams are a way to coordinate the balance of the human psychological world, especially for people's attention, emotions and cognitive activities.

Not only is dreamless sleep not only poor, but it is also a sign of brain damage or disease.

Recent research has also confirmed the idea that dreams are the result of the brain's regulatory center balancing various functions of the body, and that dreams are necessary for the healthy development of the brain and the maintenance of normal thinking. If the regulatory center of the brain is damaged, dreams cannot be formed, or there are only some incomplete dream fragments, and if there is no dreamless sleep for a long time, it is worth people's vigilance. Of course, if you have nightmares for a long time, it is also a sign of physical weakness or certain diseases.
