A cooling pranayama that draws breath across a curled tongue like a straw, said to cool the body and calm irritability.
In warm weather, after heating exercise, or any time you feel overheated, flushed, or irritable and want to cool both body and temper.
Drawing a slow breath across a wet, curled tongue cools and humidifies the incoming air by evaporation (the same reason a breeze feels cool on damp skin) which is the physical basis for the refreshing 'cooling' sensation the practice is named for. Layered on top is a long, slow exhale through the nose, which nudges the nervous system toward its calmer, parasympathetic side, so the effect is both a cooler mouth and throat and a steadier mind.
Any measured, whole-body cooling from Sitali is modest and mostly subjective; a few small studies suggest short-term drops in blood pressure, but the evidence base is thin. In yoga it is classically prescribed for excess 'heat' (irritability, hot flushes, warm weather) a traditional indication rather than a clinical one. Treat it as a safe, pleasant way to feel cooler and calmer in the moment, and mind the note below about cold, dry air.
Sitali (also spelled Shitali) means 'cooling' or 'soothing' in Sanskrit. It is one of the classical cooling pranayamas described in hatha-yoga texts such as the Hatha Yoga Pradipika, where it is recommended to reduce excess internal heat and pacify the fiery pitta quality of the Ayurvedic scheme. The curled-tongue technique it depends on relies on a bit of anatomy not everyone shares (the ability to roll the tongue into a tube) which is exactly why its sibling practice, Sitkari, exists.
Begin with six rounds of a slow cooling inhale and a relaxed nasal exhale. As it becomes familiar, gradually lengthen and smooth both phases; on hot days or after intense exertion you can extend to several minutes, stopping if the cool, dry air starts to feel harsh in the throat.
I can't curl my tongue, can I still do this?
Yes. Use Sitkari instead, drawing the breath over your teeth. The ability to roll the tongue into a tube is partly genetic, and Sitkari gives the same cooling effect.
When is the best time to practice?
In warm weather, after heating exercise, or any time you feel overheated or irritable, the practice is traditionally used to cool both body and temper.
Does it actually lower my temperature?
It cools the mouth and throat noticeably and can feel refreshing all over, but any whole-body cooling is small. Think of it as a soothing, cooling sensation rather than a way to break a fever.

Breathwork is a complement to (not a replacement for) professional medical care. If you have a heart, respiratory, or blood-pressure condition, are pregnant, or feel unwell, check with a clinician before practising breath-hold techniques.
