The causes of night sweats (abnormal sweating after going to sleep and stopping after waking up) in children are mostly related to a deficiency of yin with heat or the sleep environment. Night sweating is a term used in Traditional Chinese Medicine (TCM) to refer to sweating during sleep. In children, night sweating is often associated with yin deficiency in Chinese medicine. In addition, it may also be related to the sleeping environment, such as the horizontal temperature is too high, the clothing is too thick, and so on. Yin deficiency: According to TCM, patients with Yin deficiency are prone to night sweating. In addition to night sweating, patients with yin deficiency may also suffer from thirst, insomnia, dreaminess, red tongue, and fine pulse. The patient can be treated with medicines that nourish yin and reduce fire, such as Angelica Six Yellow Soup. Sleeping environment: If the child sweats more at night, it may be related to the room temperature and the clothes and blankets, so the room temperature should be adjusted appropriately and the clothes and blankets should be increased or decreased. For children with night sweats, it is recommended that they go to a regular hospital and be treated under the guidance of a professional physician.
