If you sleep eight hours a day, you will spend one third of your life in sleep. The quality of sleep is closely related to people's psychological and physical health. Sleep has four elements, which have a great influence on sleep quality. ? Sleep equipment? Whether it is a bed in the south or a kang in the north, it should be placed or built in the north-south direction. People sleep with their heads facing north and their feet facing south, so that their bodies will not be disturbed by geomagnetism.

The hardness of the shop should be moderate, and the excellent shop will make people have to turn over from time to time because of its stimulation, and it is difficult to sleep, and the whole body aches after sleeping; Generally, the height of the pillow should be one shoulder of the sleeper (about 10 cm), too low will easily lead to physiological spur of cervical spine. Pillows should be aired frequently in summer to prevent germs from entering the mouth and nose, and lung diseases will increase. ? Sleeping posture? People with heart disease, it is best to lie on the right side, so as not to cause heart pressure and increase the incidence; If brain pain is caused by hypertension, the occipital position should be raised appropriately; In addition to raising pillows, patients with lung diseases should often change their sleeping positions to facilitate the discharge of phlegm and saliva.

Sleep time Sleep time should generally be maintained at 7 to 8 hours, but it is not necessary, depending on individual differences. Those who fall asleep quickly and deeply generally have no dreams or fewer dreams, and they can fully recover their energy after sleeping for 6 hours; People who fall asleep slowly and shallowly, have a lot of sleep eyes and often have nightmares still don't feel refreshed even after sleeping for 10 hours. They should get effective sleep through various treatments, but prolonging sleep time is harmful to their health. Because everyone's physiological rhythm is different, the arrangement of going to bed in the morning and evening also varies from person to person! In fact, different circadian rhythms cause two kinds of sleeping situations, namely "night owl" and "lark".

Conforming to this physiological rhythm is conducive to improving work efficiency and quality of life, and vice versa. ? Sleep quality is closely related to sleep environment. You can have a good sleep at the temperature of 15 to 24 degrees. In winter, the smoke left by smoking after closing doors and windows, as well as the escaping incomplete burning gas, will also make people unable to sleep peacefully. People who live near high-frequency ionizing electromagnetic radiation sources and have poor sleep for a long time rather than their own diseases, it is best to move to a distant place to live. To sum up, if people can master the four elements of scientific sleep, they can effectively improve the quality of sleep and put more energy into it.
