Snana (bath)
Snāna स्नान
Also: bath, Sarvanga-snana
Bathing as a daily ritual.
Sushruta Cikitsa 24.33: “Bathing removes somnolence, bodily heat and a sense of fatigue. It allays thirst and checks itching and perspiration, brings on a fresh relish for food, removes all bodily impurities, clears the sense-organs, gladdens the mind, purifies the blood, increases the appetising power, destroys drowsiness and sin, and increases semen. The sight of a man is invigorated by applying cold water to the head at the time of bathing, while the pouring of warm water on the head tends to injure the eye-sight.”
The critical rule: warm body, cool head
The classical Ayurvedic bath uses warm water on the body, cool water on the head. Hot water on the head:
- Damages eye-sight (Sushruta’s explicit warning)
- Aggravates Pitta of the scalp (manifests as premature greying, dandruff)
- Damages hair follicle integrity
Modern shower discipline: never let hot water spray your face or scalp. Wash hair with lukewarm (not hot) water.
