Summer Heat (Shu) is the only pathogenic factor in TCM that occurs exclusively in one season — summer. It is purely an external pathogen with no internal counterpart. Summer Heat is a Yang pathogen that shares Heat's tendency to flare upward and consume fluids, but it has distinct characteristics that set it apart: it always arises from exposure to extreme summer temperatures and frequently combines with Dampness, reflecting the humid conditions that often accompany hot weather.

Summer Heat symptoms include high fever, heavy sweating, intense thirst, fatigue, irritability, a red face, and a surging, rapid pulse. Because excessive sweating depletes both fluids and Qi simultaneously, Summer Heat often produces a characteristic combination of heat signs with sudden exhaustion — the TCM understanding of heat exhaustion and heatstroke. When Summer Heat combines with Dampness (Shu Shi), additional symptoms include nausea, heavy limbs, chest oppression, loose stools, and a greasy tongue coating.

Prevention and treatment follow the principle of clearing heat and generating fluids. The classic formula Qing Shu Yi Qi Tang (Clear Summer Heat and Augment the Qi Decoction) addresses the combined fluid and Qi depletion. Watermelon rind (Xi Gua Pi) is a traditional Chinese medicinal used specifically for Summer Heat. Acupuncture at points like GV-14 (Dazhui) and LI-11 (Quchi) helps clear heat, while SP-6 (Sanyinjiao) supports fluid generation.
