Sweating from 3:00 am to 5:00 am is called yin deficiency night sweating in Chinese medicine (abnormal sweating after going to sleep and stopping sweating after waking up), which can be regulated by medication and acupuncture. 1. Medication: If the patient has sweating from 3:00 to 5:00 a.m., accompanied by symptoms such as “five heart-heat” (heat in the hearts of the hands and feet, and conscious of the heart and chest), “hot flashes” (a burst of heat), “bone vapor”, “soreness of the waist and knees” (a feeling of soreness and weakness of the waist and knees), “dry stools”, and “red tongue” with little moss, then Zhi Bai Di Huang Pills or Six-flavored Dihuang Pills may be taken as a treatment. 2. Acupuncture: When patients sweat from 3am to 5am, acupuncture can be used to nourish the yin fluid in the body and alleviate the symptoms of yin deficiency and night sweating by needling acupuncture points such as Taixi Point and Sanyinjiao Point. When sweating is more serious from 3:00 to 5:00 a.m., it is recommended to go to the hospital in time to be diagnosed by the doctor to give treatment, do not self-medication or acupuncture operation.
