A bad liver may affect sleep. In Chinese medicine, bad liver includes liver yin deficiency, liver blood deficiency (liver blood insufficiency), liver depression and qi stagnation (poor qi and blood transportation in the liver, depression), and liver fire inflammation, all of which may affect sleep to varying degrees, resulting in insomnia and so on. Bad liver is mostly seen in symptoms such as dizziness, depression or irritability, etc. Specifically, there are different kinds of Yin deficiency, blood deficiency, stagnation of qi, and hyper-heat of the liver. If the liver yin deficiency deficiency, the organism is not nourished, can lead to disturbed mind and now insomnia and irritability and other symptoms. Liver depression and stagnation of qi will result in liver loss of detachment (abnormal function of liver detachment), and depression can lead to insomnia and nightmares. Liver fire, disturbing the mind, can also be seen as irritability, difficulty in sleeping, and so on. When discomfort occurs, one should consult a doctor in time and choose medication under the guidance of the physician’s diagnosis to avoid delaying the condition.
