Also called:Night sweatsSleep sweatingNocturnal sweating

From the TCM perspective: TCM 'dao han' / 'qin han'; located in heart and kidney, involving liver and spleen.

Overview

Night sweats are sweating during sleep that stops on waking, named like a thief coming at night. In TCM the common patterns are yin deficiency with effulgent fire and insufficient heart blood; damp-heat and dual qi-yin deficiency also occur. In chronic illness deficiency causes sweating, and sweating further consumes yin.
