Difficulty in falling asleep at night due to heat in the back may be caused by liver depression and fire (liver qi does not work, resulting in fire and heat), yin deficiency and fire (deficiency of yin and essence in the body, resulting in hyperactive fire), etc. In Chinese medicine, this may be due to liver depression and fire (liver qi does not work, resulting in fire and heat). 1. Liver depression and fire: If the patient is attacked by illness or mental shock, it may also cause the liver’s excretory function to become dysfunctional, which in the long run will lead to liver depression and fire, resulting in localized burning and discomfort, such as back heat, making it difficult to fall asleep, and so on. 2. Yin deficiency and exuberant fire: patients who are older, or too much intercourse, overwork and other circumstances may also lead to excessive loss of body Yin deficiency, thus appearing at night by the heat of the symptoms difficult to sleep. It is recommended that patients should closely observe their own recovery, if the condition is malignant, should also go to the hospital in a timely manner for relevant consultation and treatment.
