Śītalī & Śītkarī: Cooling the Body, Calming the Mind

Ancient cooling techniques for pitta and a heating planet

The cooling prāṇāyāmas śītalī and śītkarī, designed to balance pitta and calm the mind, actually lower body temperature measurably. In our warming world, these ancient techniques offer wisdom that goes beyond air conditioning.

Śītalī & Śītkarī: Cooling the Body, Calming the Mind

It is May in Rajasthan. The temperature has crossed 47°C for the third consecutive day. In Jaipur, air conditioners strain against the brutal heat while power grids threaten collapse. Office workers huddle near vents, delivery workers collapse from heatstroke, and news channels warn the elderly to stay indoors.

But in a small village outside Jodhpur, an elderly woman sits in the shade of a neem tree, seemingly unbothered. Asked how she manages the heat, she demonstrates: she rolls her tongue into a tube, inhales slowly through it with a soft hissing sound, then exhales through her nose. "Śītalī," she says simply. "My grandmother taught me. The breath brings cold from inside."

She learned this technique not from a yoga studio or a wellness app, but from generations of women who survived Rajasthan's brutal summers without electricity. What she practices, and what modern yoga students often skip as "too simple", is one of the most practical prāṇāyāma techniques ever developed: a breath that literally cools the body.

The Cooling Breaths: Two Approaches, One Purpose

The Haṭha Yoga Pradīpikā describes two primary cooling techniques:

Śītalī (the cooling breath): The practitioner rolls the tongue into a tube shape and inhales through this "straw," drawing air across the moist tongue surface. The evaporative effect, the same principle that makes sweating effective, cools the incoming air before it enters the lungs. This cooled air then circulates through the body.

Śītkarī (the hissing breath): For the approximately 35% of people who genetically cannot roll their tongues, the texts provide an alternative. The teeth are lightly clenched, lips drawn back, and air is inhaled through the gaps between the teeth with a hissing "seeee" sound. The air passes over the moist surfaces of the mouth, achieving similar cooling.

Both techniques end with exhalation through the nose, and both can be practiced with or without kumbhaka (retention).
