"What to do, I'm about to turn in the papers, I still have half of the questions not written..."
"Ah how this dog chased so tightly, I can't run!" How come there is no one around..."
At the first moment, you suddenly open your eyes: Ah, it was just a dream!
I believe that many people have such an experience, after waking up from a nightmare, the mood can not be calm for a long time, and even after a few days can remember the details of the dream, the stamina is not small.
So is it a "bad omen" to always have nightmares? A recent study seems to confirm this.
<h1 class = "pgc-h-arrow-right" >: Some dreams may indicate the onset of disease</h1>
Scientists have been studying the relationship between dreaming and human health, and multiple studies have shown that if the content of dreams is vivid and interesting, then the quality of sleep is better and eating habits are healthier; frequent nightmares and sleep disorders, and the risk of Parkinson's disease and related neurodegenerative diseases is higher; dreaming less at night may be a sign of sleep apnea; nightmares may be related to heart disease, which can reduce oxygen intake in the brain and disrupt sleep.
However, the use of dreams and their content as health warnings has been controversial, but many researchers have pointed out that some interesting results may suggest that premonition dreams or pre-detection of symptoms may be a warning of health problems.
Deleddley Barrett, a researcher at Harvard Medical School, former president of the International Association for the Study of Dreams, and author of The Sleep Council, gives two examples in her book:
Someone dreamed that a leopard was biting on his back, and when he woke up, he found that there was a mark on that part, so he went to see a doctor. Another patient had something on his body, but did not pay attention to it, and then had several related dreams, one of which made it clear that the patient was going to check it, so the patient went to the hospital for examination and found that it was early melanoma.
Barrett believes that when people are awake because of many things, the dream captures some subtle reactions when the body is out of condition.
<h1 class= "pgc-h-arrow-right" > Second, why do people dream? </h1>
After people fall asleep, the brain also goes to sleep, but a small part of the brain cells are still active, which is the basis of dreams.
Under normal circumstances, people's sleep is divided into non-REM sleep period and REM sleep period, alternating once for a sleep cycle, people generally have 4 to 5 sleep cycles per night, each cycle is about 90 to 110 minutes. Most dreams occur during RAPID EYE movement sleep, during which the body's activity is low, the body receives information from the brain, paralyzing the muscles, and accompanies the dream to prevent the body from moving around and being injured.
Under normal circumstances, human beings have 4 to 6 dreams a night, but many people can't remember or even think that they haven't dreamed, and some people feel that they have a night's dream.
Dreams occur during REM sleep, if we wake up during this period, we will remember the dream more clearly, if you wake up in other periods, often can not remember the dream clearly, and even think that you are not dreaming.
<h1 class= "pgc-h-arrow-right" > three, dreaming indicates that sleep quality is not good? </h1>
Dreaming is the expression of people's subconscious, but also a mechanism to protect sleep, and does not indicate that the quality of sleep is not good. Generally speaking, people will have 4 to 6 dreams a night, and what makes people sleep badly is not dreams, but physical or mental reasons, affecting their sleep quality, making people remember their dreams, and causing the feeling of frequent dreams.
For example, when the mental pressure is high, people may have some nightmares, let people wake up, and then it is difficult to fall asleep, the brain feels tired; people with neurasthenia have difficulty falling asleep, and it is easy to wake up after falling asleep, so they are listless during the day.
Scientists have done experiments to put the experimenter to sleep, and the researchers woke him up when he had a "sleep brainwave" and did not let the dream continue, and so on.
It was found that the deprivation of dreams will cause the human body to produce a series of physiological abnormalities, such as increased pulse, body temperature, blood pressure, etc., weakening of autonomic nervous system function, etc., and will also cause a series of psychological reactions, such as tension, anxiety, hallucinations, memory impairment, etc. Therefore, dreaming not only does not affect sleep, but may be beneficial to physical and mental health, dreams are a way for the human body to coordinate the balance of the mental world.
<h1 class="pgc-h-arrow-right" > four, what to do if you often have nightmares? </h1>
Psychologists say that nightmares are the release of feelings such as shyness, guilt, fear, anxiety and so on during the day, and occasional nightmares are not detrimental to human health, and can also regulate emotions. But if you often have nightmares, it will reduce the quality of sleep and reduce immunity.
The scientific community has roughly two conjectures about the causes of frequent nightmares.
First, there are some psychological and emotional problems. The most common are anxiety and depression, these emotional problems interfere with sleep, making it difficult for people to fall asleep, waking up easily, and feeling tired after waking up. Sometimes the sleep problems caused by mood swings are more hidden, some people are less likely to think about this aspect, and it is easy to fall into a vicious circle: anxiety/depression → poor sleep → poor daytime state → anxiety/depression.
Second, it may also be a signal from a certain disease. During the day, stimuli from the outside world mask disease signals, and at night, when the body receives less information, these weak signals are constantly sent into the brain, leading to frequent nightmares. Some scholars believe that frequent nightmares may be damaged blood vessels in the brain or poor blood flow, indicating the possibility of migraines and cardiovascular disease. Nightmares all night long, possibly chronic pain such as joint pain and low back pain.
So, how do you solve the nightmare?
For emotional nightmares, psychological treatment can be used first, and if necessary, drug treatment, the most commonly used first-line antidepressants are sertraline, paroxetine and so on. Short-term psychological problems can try to self-regulate, if it lasts for more than 2 weeks, it is recommended to seek medical treatment as soon as possible, the longer you carry it, the worse the situation may be.
Nightmares that are not emotionally induced can be a physical disorder and it is recommended to seek medical examination.
Everyone dreams, if it's just an occasional nightmare, it's not a big problem, it may just be that the daytime events affect the mood, or watch some bloody violence, horror and spooky movies, or it may be that the sleeping position is too poor, find out the cause, avoid the problem.
