Close the window when sleeping, and don't turn on the fan and air conditioner. Many people will get sick. Because the blood circulation is slow and the body temperature drops during sleep, the body will form a positive layer on the body surface. This positive layer makes people call it "ghosts don't invade." What do you mean? People with full yang don't have nightmares. It is this Yang who has the upper hand. Turning on the air conditioner is different from turning on the fan. Open the window, and the wind will get into the ribs. If you turn on the air conditioner, there will be wind, and the wind will get into the ribs. When I get up in the morning, my body turns yellow, my face turns yellow, the tendons at the back of my neck become stiff and my joints ache. Some people even start to have a fever. This is why the cold attacks the bones and muscles. This is also a gas injury. The best effect is not to open windows, air conditioners, fans and doors at night. If it's hot, opening the door and closing the window will be less effective, but he won't be tired and stiff when he gets up the next morning.
Warm limbs when sleeping, because limbs are the foundation of yang, which is known to all. If the limbs are not warm, it must be kidney yang deficiency. Before going to bed, cover your hands and feet, your navel and the life gate behind you.
Sleep must get up early, even in winter, don't get up before 6 o'clock, and get up before 5 o'clock in spring, summer and autumn as far as possible, because getting up in Yin Shi (3 o'clock to 5 o'clock) with developed lung meridians can stretch the lung qi, so as to adapt to the relaxation of Yang Qi, complete metabolism, eliminate turbid qi and make the lung qi unobstructed. This will help nourish the lungs, conform to the natural trend of the sun, and improve the Yang Qi of human beings and make people a day in Yang Qi.
From 5: 00 am to 7: 00 am, it is the peak period of the large intestine meridian, and the human body needs to expel the polluted gas of metabolism. At this time, if you don't get up, the large intestine can't exercise fully, and you can't complete the function of removing turbidity well, so that turbidity stays and forms toxins, which are harmful to human blood and viscera. From 7: 00 to 9: 00 in the morning, the stomach meridian is the most prosperous, and from 9: 00 to1point, people's digestion, absorption and transport are the best. If you don't get up at this time, gastric acid will seriously corrode the gastric mucosa, and people will not get nutrition at the best time to absorb nutrition. After a long time, they will suffer from spleen and stomach diseases, leading to malnutrition and gas collapse. So don't lie in bed, it will cause dizziness.
