● Sleep direction
"A $ one thousand party? Tao Lin raises nature and thinks that spring and summer belong to the sun, and his head should lie east; It is cloudy in autumn and winter, and the head should lie facing west, in order to conform to the principle of "nourishing yang in spring and summer and nourishing yin in autumn and winter". And put forward: to avoid lying in the north, ancient health experts are basically the same on this point. It is believed that the north belongs to the yin position of water and yin, which is mainly responsible for winter cold, and the north is afraid of lying in the yin cold, which directly hurts the human body Yuanyang and damages Shenyuan's house. Clinical investigation shows that the incidence of cerebral thrombosis in the elderly lying with head north and feet south is higher than that in other lying positions. Foreign data show that lying with the head north and feet south is easy to induce myocardial infarction.
However, some health experts argue that the head should lie in the east all the year round, not because of the changes of the four seasons. The head is the meeting of all yang, the highest place of human body, and the place where qi and blood rise, while the East Earthquake is the main spring, which can rise the qi of all things. Therefore, the head lying in the east can ensure that the head is clear and turbid, and the mind is clear.
● Sleep posture
1, ordinary people should lie on their right side. 2. Pregnant women should lie on their left side. 3. The elderly should not lie on their backs, prone or on their left side, but on their right side. For patients with heart failure and cough and asthma, it is advisable to take a semi-lateral position or a semi-sitting position, and at the same time raise the occipital back. For patients with pleural effusion caused by lung diseases, it is advisable to lie on the side to make the position of pleural effusion the lowest and not interfere with the respiratory function of healthy lungs. For patients with heart disease with blood stasis symptoms, such as cor pulmonale, it is generally not advisable to lie on your side or prone to prevent the heart from being overloaded. Sun Simiao also pointed out that "mortals should not hang their feet on high places when sleeping, but become kidney water after a long time". Sleeping head down and feet up is easy to get kidney disease.
● Sleep and bedding
1, the hardness of the bed should be moderate. A bed with moderate hardness can ensure the normal physiological curve of the spine, relax muscles and help to recover from fatigue. Too soft a bed will increase the load of ligaments and joints around the spine, make muscles passive and tense, and cause low back pain for a long time.
2. Pillows. A suitable pillow can help relax the whole body, protect the neck and brain, promote and improve sleep, and prevent and treat diseases.

● Avoid sleeping.
1, contraindications before going to bed: it is not advisable to eat enough, be hungry or drink a lot of water and strong tea, coffee and other drinks before going to bed. Lying down after a full meal, the spleen and stomach can not be transported, food stagnation in the chest and stomach, dampness into phlegm, great harm to yang. When you go to sleep hungry, you are too hungry to sleep. Drinking plenty of water before going to bed is also inappropriate, which will damage the spleen, prevent water from getting wet, increase nocturia and even hurt the kidney. It is not advisable to drink stimulating drinks before going to bed, and avoid alcohol and tobacco to avoid falling asleep. Don't be too emotional before going to bed, read and think. When you are overjoyed and furious, you are distracted. When you are extremely worried about reading, you will be restless and impetuous, which will lead to the disorder of qi activity and the yang failing to enter the yin. Don't do strenuous exercise before going to bed, so as not to affect sleep.
2, taboos in sleep: avoid sleeping with wind, for fire, for light. When sleeping, the head is facing the vents of doors and windows, which is easy to cause facial paralysis and hemiplegia. When you lie with your head facing the fire to keep warm, it is easy for the fire to attack the coke, causing dry throat, red eyes, nosebleeds and even headaches. When I was lying down, my head was facing the light and I was very sleepy. You should avoid covering your head when you sleep. The book Daolin Nourishes a Thousand Women says: "Longevity without covering your head in winter nights" means "freezing your brain", which can make your breathing smooth and your brain adequately supplied with oxygen.
3, taboo after waking up: the ancients said: "The early riser lives long", so I can't fall in love with bed after waking up. Sleeping late is not conducive to the declaration of human yang, which makes qi stagnate and easily leads to stagnation. In addition, don't get angry or angry after getting up, which is very harmful to God. It is considered that this affects the changes of qi, blood, yin and yang in one day and is extremely harmful to health.
