Usually, dreams occur during light sleep, and nightmares are when people wake up from deep sleep. The central nervous system that controls people’s actions is still in a dormant state, while part of the central nervous system that can convey consciousness is active, leading to the situation that people are conscious but unable to move.
Gong Shouhui said that nightmare is a symptom of sleep paralysis (paralysis) in sleep Neuromedicine.
In addition to lying on your back, there are other incentives, such as sleeping with your chest facing down, or sleeping with your head covered, or having a thick quilt or hands on your chest, being too nervous during the day, and having too much dinner.
Long term high pillow will not only compress carotid sinus, but also affect smooth airway and snore, and easily lead to neck discomfort or hunchback. It will keep the head at the highest position in the human body; It will also artificially change the natural physiological curvature of the cervical spine, so that the tense tendons and skin compress the meridians of the neck. If the blood vessels of the head are in a state of insufficient blood and oxygen supply for a long time, it will make people upset and difficult to fall asleep at night. Once they fall asleep, it is easy to have nightmares.
When the head is in the condition of insufficient blood and oxygen supply for a long time, it will affect the metabolism of brain cells, lead to memory loss, and lead to brain dementia and brain atrophy in the middle-aged and old people in advance. It is easy to cause hardening of blood vessels, and physiological garbage can not be cleared in time to form thrombus, leading to cerebral infarction and cerebral hemorrhage.
From the physiological point of view, the pillow should be 8-12 cm. Try to sleep on your right side, and avoid the above incentives, so that nightmares will not occur. Don’t go to bed before you are too tired to knock. If you are very tired, you may have a nightmare after you dream.
