Sitkari Pranayama: How Often and How to Practice It
A cousin of sitali, practiced through clenched teeth rather than a curled tongue, sitkari pranayama cools and calms quickly. Here is how often to practice it, and what a clinical study shows about its effects.
Sitkari pranayama is practiced by slowly inhaling through clenched teeth, tongue pressed to the palate — unlike sitali pranayama, which uses the tongue curled into a tube. Both techniques share the same cooling effect, useful for excess Pitta or in hot weather, but sitkari remains accessible to those who can't curl their tongue.
Our article on sitkari pranayama details the technique step by step; this one answers the practical question of frequency and best timing, drawing on a clinical study that tested precisely this pair of techniques.
How often to practice sitkari pranayama?
| Goal | Recommended frequency | Duration per session |
|---|---|---|
| One-off cooling (heat, anger, irritability) | As needed, no strict limit | 1 to 3 minutes, a few breath cycles |
| Regular baseline practice (chronic Pitta excess, mild tension) | Daily, ideally late morning or evening | 5 to 10 minutes |
| Supervised course (on the model of the clinical study) | 6 days out of 7, over several weeks | 15 to 20 minutes, combined with sitali |
What is the best time of day?
Sitkari, like sitali, is traditionally discouraged early in the morning in cold weather or during winter, when its cooling nature can amplify an already-present feeling of cold. It's best practiced in summer, during the hottest hours of the day, or year-round in cases of marked Pitta excess (hot flashes, irritability, a burning sensation). Practicing late morning, before a meal, or in the evening to calm mental agitation, suits most profiles.
What does research show on sitkari pranayama?
A randomized controlled trial by Shetty, Kumar Reddy, Lakshmeesha, Shetty, Selva Kumar and Bradley, published in 2017 in Integrative Medicine: A Clinician's Journal, tested precisely the sheetali and sheetkari (sitkari) pranayamas duo in hypertensive patients, at a clinical research center in India. The results show a significant drop in systolic blood pressure, respiratory rate and heart rate in the group practicing both breathing techniques, compared with the control group (see the study on Google Scholar). This is an encouraging but isolated trial, conducted in a limited sample: it in no way exempts anyone from a prescribed antihypertensive treatment or medical monitoring of blood pressure.
How to practice a simple session?
- Sit comfortably, back straight, in a stable posture (Ayurvedic meditation posture or simply seated on a chair).
- Lightly clench your teeth, part your lips slightly, tongue pressed to the roof of the mouth.
- Inhale slowly through the small opening between your teeth, feeling the coolness of the air on your tongue.
- Close your mouth, exhale slowly through the nose.
- Repeat 8 to 12 cycles for a one-off session, more for a longer baseline course.
Sitkari or sitali: which to choose?
Both techniques aim for the same cooling effect and can be used interchangeably based on personal preference: sitkari suits those who can't curl their tongue into a tube (a genetically variable trait), while sitali remains the more widely taught historical reference. The Shetty and colleagues study, in fact, tested both techniques together, without seeking to determine which was more effective.
Precautions
Sitkari pranayama is discouraged for people with asthma or bronchial sensitivity to cold, since inhaled cold air can trigger breathing discomfort in sensitive individuals, as well as for people with marked tooth sensitivity (cold air passing over the teeth can be uncomfortable) or in very cold weather. People already experiencing low blood pressure or on antihypertensive treatment should practice with caution and monitor their blood pressure, since the available study shows a measurable effect on blood pressure. This practice never replaces medical treatment for hypertension; it may accompany it, with the treating doctor's approval. General guidance is available in our safety and precautions guide.
Your questions about sitkari pranayama
How often should sitkari pranayama be practiced?
Daily for baseline use (5 to 10 minutes), or as needed on a one-off basis (heat, irritability — a few cycles suffice). A supervised course on the model of clinical studies goes up to 15-20 minutes, 6 days out of 7.
What is the difference between sitali and sitkari?
Sitali is practiced with the tongue curled into a tube, sitkari through clenched teeth with the tongue pressed to the palate. Both share a similar cooling effect; sitkari suits those who cannot curl their tongue.
Does sitkari pranayama lower blood pressure?
A 2017 clinical trial showed a significant drop in systolic blood pressure in hypertensive patients practicing sitali and sitkari together. This does not replace a prescribed medical treatment.
When should sitkari pranayama be avoided?
In cases of asthma, bronchial sensitivity to cold, marked tooth sensitivity, or very cold weather. People with low blood pressure should also practice with caution.
Can sitkari be practiced in the morning in winter?
It's not ideal: its cooling nature can amplify a feeling of cold. It works better in summer, during the hottest hours, or in cases of marked Pitta excess regardless of season.
