There are many factors that lead to poor sleep quality, in order to delve into its essence, we can look for clues from the motherland's medical classic "Yellow Emperor's Neijing". In "The Yellow Emperor's Neijing", is there an expression corresponding to sleep? In fact, in the "Yellow Emperor's Neijing", what is related to sleep or has a similar meaning is one word - "lying". The meaning of this word is different from what we are used to in our daily life. What we call "lying down" today may mean lying down or staying, but it doesn't necessarily mean falling asleep. However, if we look at the purpose of "lying down", there seems to be something similar between the ancient and modern truths: when the human body is weak or tired, people will want to lie down and rest, even if they do not fall asleep, this state is the same as the essential purpose of sleep, which is to rest and recover. Therefore, we can think that the word "lying" in the "Yellow Emperor's Neijing" not only represents sleep, but also covers the meaning of rest. This emphasis on rest underscores the importance of sleep in maintaining good health, and reminds us that even when we are not sleeping, we can have a positive impact on our physical health if we are well rested. 
As a classic work of traditional Chinese medicine theory, the Yellow Emperor's Neijing has an in-depth study of human health and diseases. Among them, sleep quality, as one of the important criteria for measuring human health, has also received extensive attention from the "Yellow Emperor's Neijing". In the Yellow Emperor's Neijing, there are many articles related to the character "lying", which reveal the factors that affect the quality of sleep, including physical condition, visceral function, and external environment. First of all, physical condition has a direct impact on sleep quality. It is mentioned in the "Yellow Emperor's Inner Canon" that when the body is overheated, it will disturb the gods and make it difficult for people to sleep. For example, when the weather is hot or when people have a fever, people often feel that their bodies are hot and unbearable, which can lead to poor sleep quality. In addition, the "Yellow Emperor's Neijing" also pointed out that when external evils invade the human body, they can also cause symptoms such as fever and shortness of breath, which will interfere with people's normal sleep. Secondly, the function of the viscera also has an important impact on the quality of sleep. "The Yellow Emperor's Neijing" believes that the five internal organs of the human body perform their own duties and coordinate with each other. When the lungs and liver are dysfunctional, the soul is restless, which can also lead to insomnia. For example, in the "Yellow Emperor's Neijing, Su Wen, and Reverse Regulation", it is mentioned that "if the stomach is not in harmony, you will be restless", which indicates that stomach discomfort will also affect the quality of sleep. At the same time, the "Yellow Emperor's Neijing, Su Wen, and Treatise on Convulsions" also pointed out: "If the syncope of Taiyin, the abdomen is full of distention, and the back is unfavorable, and if you do not want to eat, you will vomit if you eat, and you will not be allowed to lie down", which shows that the dysfunction of the spleen and stomach will also interfere with sleep. Finally, the influence of the external environment on sleep quality cannot be ignored. It is mentioned in the "Yellow Emperor's Neijing" that when the external environment changes, the human body will also react accordingly. For example, in the "Su Wen Bi Treatise": "People with liver paralysis will be frightened when they lie down at night, and drink more and urinate a lot", which shows that changes in the external environment may cause discomfort to the human body, thereby affecting the quality of sleep. At the same time, it is mentioned in the "Su Wen Contrarian Theory": "The husband is not allowed to lie down, and those who are wheezing when they lie down are also the guests of water and gas", which shows that the flooding of water and dampness will also interfere with sleep. 
In the Yellow Emperor's Neijing, the description of "not lying down" actually reveals a problem that is closely connected to the three main organs – the stomach, liver, and lungs. From the perspective of traditional Chinese medicine, when the function of these organs is disordered, it often leads to insomnia or difficulty falling asleep. Specifically, if the function of the stomach is not coordinated, it may trigger digestive discomfort, which can affect the quality of sleep; Abnormalities in the liver can lead to mood problems such as depression and anxiety, which can interfere with sleep. Lung disorders, such as fever, shortness of breath or wheezing, can also interfere with the normal sleep process. When dealing with short-term sleep problems, we should first consider adjusting these three organs. First of all, the adjustment of the spleen and stomach is the key. It is advisable to avoid excessive eating before bedtime, especially for those who have a late dinner or a late-night snack habit, as this may add to the burden on the stomach. If you really need to eat something in the evening, opting for a light meal and putting it off can be a compromise. Secondly, the adjustment of the breath should not be overlooked. Due to the "lungs are the main body of qi", it is necessary for those with weak lung function to do some pranayama exercises before going to bed. This not only soothes the discomfort in the lungs, but also helps to calm the mood. For example, meditation and pranayama, deep breathing, or yoga are all good options. These activities are not only beneficial to the lungs, but also have a conditioning effect on the liver. Because the "liver main drainage" is closely related to the rise and fall and flow of qi in the body. So, balancing the breath through pranayama is actually a way to kill two birds with one stone.
