TCM for Heat Stroke and Summer Heat Exhaustion
Learn how TCM prevents and treats heat-related illness 鈥?from mild heat exhaustion to serious heat stroke. Includes cooling herbs, emergency acupressure, and the essential summer formula Huo Xiang Zheng Qi San.
A Personal NoteI grew up thinking heat exhaustion only happened to people exercising in direct sun. After learning about TCM's concept of summer heat (鏆? shu) as a specific external pathogen, I realized it affects everyone 鈥?even people in air-conditioned offices 鈥?by gradually depleting qi and fluids. The Chinese understanding of summer heat as a clinical entity with stages 鈥?from mild fluid depletion to full collapse 鈥?is more refined than anything I encountered in Western medicine.
Summer Heat as a Pathogen
Summer heat (鏆戦偑) is unique among the six external pathogens:
- It rises, expands, and moves upward
- It consumes fluids and damages qi
- It often combines with dampness (鏆戞箍) in humid weather
| Stage | TCM Term | Western Equivalent |
|---|---|---|
| Mild fluid depletion | 伤暑 | Mild heat exhaustion |
| Qi and yin damage | 暑热 | Moderate heat exhaustion |
| Collapse of qi | 中暑 | Heat stroke 鈥?EMERGENCY |
