if you sleep eight hours a day, one third of your life is spent in sleep. The quality of sleep is closely related to people’s mental and physical health. Sleep has four elements, which have a great impact on the quality of sleep.
sleeping utensils
whether the bed in the South or the Kang in the North should be placed or built in a north-south direction. When people sleep, their head is north and their feet are south, so that the body is not disturbed by geomagnetism. The hardness of the shop should be moderate. An excellent shop will make people have to turn over often because of its stimulation, which is difficult to sleep, and the whole body is sore after sleep; Pillow height is generally suitable for one shoulder (about 10 cm) of the sleeper. Too low is easy to cause physiological bone spur of cervical spine. In summer, pillows should be often turned and dried to prevent bacteria from entering the mouth and nose and increase lung diseases.
sleeping posture
for people with heart disease, it is best to lie on the right side to avoid increasing the incidence of heart compression; If the brain is painful due to high blood pressure, the occipital position should be properly padded; In addition to the high pillow, patients with lung system should often change their sleeping side to facilitate the excretion of phlegm and saliva. For those with fullness of stomach and hepatobiliary diseases, it is appropriate to sleep on the right side; If there is pain in the limbs, lie down to avoid pressing the pain. In short, choosing a comfortable and conducive sleeping position is conducive to a good sleep.
sleep time
sleep time should generally be maintained for 7 to 8 hours, but it is not necessarily mandatory, which should depend on individual differences. Those who fall asleep quickly and sleep deeply, generally have no or few dreams, and can completely recover their energy after sleeping for 6 hours; Those who fall asleep slowly and shallow, have many eyes, often have many dreams and nightmares, even if they sleep for 10 hours, it is still difficult to be refreshing. They should get effective sleep through various treatments, but prolonging the sleep time is harmful to their body. Because everyone has a different physiological rhythm, the arrangement of sleep in the morning and evening should vary from person to person! In fact, different physiological rhythms lead to two situations of sleep, namely & ldquo; Night owl & rdquo; And & ldquo; Lark & rdquo;. Conforming to this physiological rhythm is conducive to improving work efficiency and quality of life. On the contrary, it is harmful to health.
sleep environment
the quality of sleep is closely related to the sleep environment. Sleep can be obtained at a temperature of 15 to 24 degrees. In winter, the smoke left by smoking after closing the doors and windows, as well as the leaked incomplete burning gas, will also make people unable to sleep. Those who live near the source emitting high-frequency ionizing electromagnetic radiation and have poor sleep for a long time, rather than their own diseases, had better migrate to live far away. To sum up, if people can master the four elements of scientific sleep, they can effectively improve the quality of sleep and invest more energy in their work. Scientific sleep is a new demand for people in modern life.
