Sheetkari (Hissing Breath)

Sheetkari — from the Sanskrit sheetkar (the hissing sound) — is the Hissing Breath, a cooling pranayama closely related to Sheetali. Where Sheetali draws the breath through a tube formed by the curled tongue, Sheetkari uses a different mechanism: the tongue is pressed lightly against the upper palate, the lips are open to expose the teeth, and the breath is drawn in through the spaces between the teeth, producing a characteristic hissing sound. Sheetkari is particularly important because it provides the same cooling therapeutic effect as Sheetali for the approximately 20–30% of people who are anatomically unable to curl their tongue into a tube.

How to Practise

Steps

1. Sit comfortably upright. Close the eyes.
2. Press the tip and blade of the tongue lightly against the upper palate (roof of the mouth).
3. Part the lips slightly, exposing the teeth. The tongue remains pressed against the upper palate behind the teeth.
4. Inhale slowly through the spaces between the teeth, drawing the air across the tongue. You will hear a clear hissing sound. The cool air flows over the tongue and into the throat.
5. At the end of the inhalation, close the mouth and retract the tongue. Apply Jalandhara Bandha briefly if practising with retention.
6. Exhale slowly and completely through both nostrils.
7. This is one round. Practise 10–15 rounds.

Benefits

• Cooling effect: Identical to Sheetali in its cooling properties — lowers body temperature and is indicated for fever, excess heat, and Pitta conditions.
• Soothes the nervous system: The hissing sound itself has a calming effect on the nervous system, similar to the effect of prolonged exhalation in other calming pranayamas.
• Benefits oral health: The drawing of air across the teeth and mouth surfaces increases saliva production and is considered beneficial for gums and teeth in traditional Ayurvedic texts.
• Reduces hunger and thirst: Classical texts specifically recommend Sheetkari and Sheetali for reducing the sensations of hunger and thirst — a practical benefit for practitioners undertaking fasting or retreat conditions.
• Accessible alternative: For practitioners who cannot perform Sheetali due to inability to curl the tongue, Sheetkari provides the same therapeutic benefits without the anatomical requirement.

Contraindications

• Cold climates, winter practice, and Kapha/Vata constitutions — same cautions as Sheetali.
• Asthma or sensitive airways.
• Dental sensitivity — those with sensitive teeth may find the cold air inhalation uncomfortable; reduce the number of rounds.

Common Mistakes

The most common error in Sheetkari is opening the mouth too wide and breathing through the mouth generally rather than specifically drawing air through the teeth. The teeth should be lightly touching or nearly so — the breath enters in a thin, controlled stream through small gaps rather than pouring in freely. Another mistake is tensing the jaw and facial muscles, which defeats the calming purpose of the practice. The face, jaw, and tongue should all remain relatively relaxed even while maintaining the specific tongue position.
