Don't use your brain too much before going to bed: If you have the habit of working and studying at night, finish the more nerve-racking things ahead of time and do some relaxing things to relax your brain before going to bed, so it's easy to fall asleep. Otherwise, the brain is in a state of excitement, and it is difficult to fall asleep even when lying in bed. It is easy to lose sleep after a long time, and the harm to the body will be greater than during the day.
Don't get angry before going to bed: only when you are in a state of "peace of mind" can you enter a deep sleep. Su Wen-On Great Pain said: "Anger leads to anger, happiness leads to anger, sadness leads to anger, fear leads to anger, and thinking leads to anger." Any emotional change will lead to qi and blood disorder, which will lead to insomnia and even disease. So don't be agitated before going to bed and prevent any emotional excitement.
It is not advisable to make sound before going to bed: Chinese medicine believes that the lungs are covered by five internal organs, which mainly make sound. When a mortal lies down, his lungs converge. Speaking at this time is easy to consume lung qi, which hurts both qi and body fluid. Just like a bell, it can't make a sound without hanging it. In addition, talking before going to bed can also make mental interest and thinking active, affect sleep and lead to insomnia. Especially after a long separation, we will talk a lot. How can I fall asleep when I am lying in bed recalling the past or telling my feelings of parting?
Don't eat before going to bed: don't be too full, too hungry or drink a lot of water and strong tea, coffee and other drinks before going to bed. "Peng Zu's Theory of Nourishing Life and Nourishing Nature" says: "If you eat enough, you will be hurt." "Bao Puzi Ji Yan" says: "It is harmful to lie down after meals." "Tao Zhenren's Health Song" says: "It is always appropriate to eat late and leave your chest and diaphragm empty." It shows that lying down after a full meal will lead to spleen and stomach failure, food accumulation in the chest cavity, dampness into disease, and great damage to yang. If you fall asleep hungry, you are hungry and it is difficult to fall asleep. Therefore, you might as well eat some food before going to bed, and then rest for a while before going to bed; If you eat in bed after lying down at night, it is even worse for your health. Of course, eating because of hunger caused by special circumstances is another matter. This should not become a habit.
Do not drink plenty of water before going to bed: drinking water will damage the spleen, keep the water wet, increase nocturia, and even damage the kidneys. It is not advisable to drink stimulating drinks before going to bed, and avoid alcohol and tobacco to avoid falling asleep.
Sleeping is not suitable for sleeping in front of a lamp: As the old saying goes, "Turn off the lights when sleeping and keep your eyes open, then God will keep his house." "Seven Signs of Yun Qi" said: "Night lights disturb people." Sleeping under the light is uncomfortable and can't sleep, even if the sleep is unstable, the shallow sleep period increases and it is easy to wake up, so be sure to turn off the lights before going to bed. Cool colors are more suitable for curtains. If the housing area is limited and there is no special bedroom, the bed should be laid in a dark corner of the room and separated from the activity area by a screen or partition.
Don't open your mouth when sleeping: Sun Simiao said "Don't open your mouth when lying in liquid" is the best way to stay active. Breathing with your mouth open has many disadvantages, which are not only unsanitary and unsightly, but also easy to make dust and cold air enter the lungs and stomach, which is extremely harmful to health. Some people not only lie with their mouths open, but also snore like thunder, which makes people around them unable to sleep, so they should practice sleeping with their mouths closed.
Don't cover your face when you sleep: some people like to sleep with their heads covered. Sleeping with your head covered will not only lead to poor breathing, but also inhale a lot of carbon dioxide exhaled by yourself, which is extremely harmful to your health. Sun Simiao of the Tang Dynasty said, "If you don't cover your head in winter, you will live a long life." As well as the ancient "three songs", there is a saying that "the preface to sleep is not covered at night", which shows that sleeping with your head covered is not good for your health.
Sleep should not be windy: after sleep, the human body's adaptability to environmental changes is reduced, and it is most vulnerable to wind and evil. "Wretched Record" said that lying down should not be the wind. "Afraid of the head wind, the back will cough when the wind blows, and the shoulder will hurt when the wind blows. Those who are good at taking pictures are not affected by the wind in midsummer. " In the hot season, if you are eager to be cool, lie in the wind, or get out of bed and get blown by the wind, resulting in abdominal pain and diarrhea, or sore joints and muscles all over your body, you should sleep in a sheltered place.
Sleeping is not suitable for the stove: when you lie down, your head is facing the stove, which is easy to be steamed by fire and anger, your head is heavy and jealous, or you are prone to colds. "Trivial Record" said: "You can't lie by the fire first, for fear of damaging your brain". Moreover, because the temperature is too high, it is easy to be pulled open after falling asleep, but it is easy to catch cold, or it is easy to catch cold when getting up at night.
