Sitkari Pranayama: The Hissing Breath Through the Teeth, a Sitali Variant

Sitkari pranayama is the most accessible variant of sitali pranayama: instead of inhaling through the tongue rolled into a tube — an ability that's partly genetic and that not everyone has — you inhale here through clenched teeth, with the tongue pressed against the roof of the mouth. The resulting sound and sensation are similar: a light hiss on the inhale, a feeling of cool air in the mouth.

This variant deserves an article of its own because, in practice, it's the one most used by people discovering these techniques — most beginners can't roll their tongue right away.

Sitkari pranayama step by step: the full protocol

1. Sit comfortably, spine straight, shoulders relaxed.
2. Clench your teeth lightly, lips slightly parted, tongue pressed against the roof of the mouth or the back of the teeth.
3. Inhale slowly through the mouth, through the gap between the teeth, producing a light "sss" hiss. The cool air passes through the mouth before reaching the throat.
4. Close the mouth, let the tongue return to its natural position.
5. Exhale slowly and silently through the nose.
6. Repeat for 8 to 12 cycles in a first session.

Unlike sitali, no special ability is needed for sitkari: that's why it's often taught first, or used as a direct alternative when the tongue can't be rolled.

What research has measured on sitkari

The same study by Telles, Gandharva, Sharma, Gupta and Balkrishna, published in 2020 in Medical Science Monitor Basic Research (vol. 26, article e920107), which assessed sitali (under its other name, sheetali), also specifically measured sitkari (see the study on Google Scholar). Among the seventeen volunteers followed, oxygen consumption increased by 7.6% during sitkari practice (versus 9.0% for sheetali), and surface body temperature also rose rather than dropped. As with sitali, these results do not confirm the traditional description of a whole-body cooling effect — even though the local sensation of coolness as air passes between the teeth remains real and widely reported by practitioners.

Sitkari or sitali: which to choose?

Criterion	Sitali	Sitkari
Accessibility	Requires the ability to roll the tongue	Accessible to everyone
Sensation	Marked coolness on the tongue	Sharp hiss, diffuse coolness in the mouth
Specific precaution	Cold outdoor air	Dental sensitivity, recent dental work
Effect measured in study	+9.0% oxygen consumption	+7.6% oxygen consumption

In practice, many practitioners alternate depending on the moment's ability or the sensation they're after: sitkari, more hissing, suits a short daytime break well; sitali, gentler, blends easily into a meditation session.

When and how often to practice sitkari pranayama?

8 to 12 cycles per session, once or twice a day, in a quiet place. Sitkari works well as a few-minute break when feeling heat or tension, for example at the end of the day, more for its immediate sensation than for an overall thermal effect that research has yet to demonstrate.

Precautions: when to avoid sitkari pranayama?

• Dental sensitivity or recent dental work: this is the precaution most specific to this variant — cool air passing between the teeth can be uncomfortable, even painful, on sensitive teeth or after recent dental treatment. Space out practice in that case.
• Cold or polluted air: as with sitali, avoid practicing outdoors in very cold weather or during marked air pollution.
• Asthma or respiratory sensitivity: ask for medical advice before starting, since breathing happens directly through the mouth without nasal filtering.
• Pregnancy: the gentle version, without forcing, is generally well tolerated, but ask your midwife or doctor before starting.
• Sitkari pranayama is a wellness tool; it replaces neither medical follow-up nor an ongoing treatment. Find our full set of cross-cutting precautions in our safety guide.
