About this practice
Day 4 introduces Sheetkari — the second classical cooling pranayama described in the Hatha Yoga Pradipika as a companion to Sheetali. Where Sheetali uses the tongue, Sheetkari uses the teeth. The two practices produce nearly identical cooling effects but feel quite different to perform; learning both gives the Pitta practitioner options across seasons and contexts.
The Hatha Yoga Pradipika groups Sheetali and Sheetkari together as the cooling breaths. Modern practitioners often prefer Sheetkari because it does not require tongue-curling ability (which is genetic) and because the teeth method is less awkward in public situations. The pranayama is also slightly gentler — useful when full Sheetali feels excessive.
The session opens with two rounds of Sheetali from previous days, then introduces Sheetkari. The technique is taught carefully: lips slightly parted, teeth lightly together, tongue tip resting behind the upper teeth, inhalation slow through the teeth producing a soft hiss. Six initial rounds at the same 6:8 ratio used for Sheetali.
The second half of the session has the practitioner alternating Sheetali and Sheetkari — three rounds each — to compare directly. Both produce cooling; one suits some days better than the other. By the end of the session, the practitioner has two reliable cooling practices in their toolkit. The closing minutes invite reflection on which technique resonates more for them today.

Practice tips
- If teeth are sensitive to cold air, exhale warmth onto the hands first, then back over the teeth before inhaling.
- Avoid Sheetkari in very cold weather; the cooling can be excessive.
- Many practitioners settle on one preferred technique after a week — both are valid; the body knows what suits.
- Sheetkari is easier to do discreetly in public — useful for daytime cooling resets.
Frequently asked questions
Which is better, Sheetali or Sheetkari?
Neither — both produce similar effects through different mechanisms. Most practitioners settle on a preference within a week. Some alternate based on the day's needs. Both are valid daily practice.
Can I skip Sheetali if I prefer Sheetkari?
Yes, once the arc is complete. Within the 21 days, practise both at least once per week to maintain fluency.
What if my teeth feel sensitive after Sheetkari?
Reduce the round count or warm the teeth with the tongue between rounds. If sensitivity persists, stick with Sheetali instead — there is no requirement to use both techniques.
