Most pranayama is subtle — the effects arrive quietly, if at all. Sitali (also spelled sheetali, from the Sanskrit sheetal, "cooling") is the exception. You curl your tongue into a straw, sip air through it, and the air arrives in your mouth measurably cooler than it left the room. It is the closest thing yoga has to a party trick, except the party is your own overheated nervous system in August.
The Hatha Yoga Pradipika lists it among the eight classic breath practices, praised for cooling the body and settling heat-driven agitation. Modern physiologists would describe the mechanism more drily — evaporative cooling across a wet tongue, plus the usual settling effect of a long, slow exhale. Both descriptions are true. Here is the practice, including what to do if your tongue refuses to roll.
How to do it
Basic sitali — the tongue straw
How: Sit upright and comfortable. Extend the tongue slightly out of the mouth and curl the sides up and in, forming a tube. Inhale slowly through the tube, as if sipping air through a straw — you will feel the coolness land on the tongue and the roof of the mouth. At the top of the breath, draw the tongue in, close the mouth, and exhale slowly through the nose. That is one round. Start with five; build toward ten.
Why: Air passing over the wet surface of the curled tongue cools by evaporation — the same reason a dog pants. The nasal exhale keeps the practice slow and controlled, and the deliberate oddness of the whole thing holds the attention better than an invisible breath ever could.
Can't roll your tongue? — sheetkari, the hissing version
How: Tongue-rolling is genetic — roughly a third of people cannot do it, and no amount of practice changes that. The classical alternative is sheetkari: teeth gently together, lips slightly parted, tongue flat behind the teeth. Inhale through the teeth with a soft hissing sound — sssss — then close the mouth and exhale through the nose exactly as before.
Why: The hiss pulls air across the wet surfaces of the teeth and gums, producing nearly the same cooling effect through a different door. The full technique is on our sheetkari page. Nobody has ever been able to tell which version a calm person used.
The settled variation — count it
How: Once the mechanics are easy, add a simple ratio: inhale through the tongue tube for a count of four, exhale through the nose for a count of six or eight. The longer exhale is where the settling lives. Keep the shoulders down and the sip unhurried — no slurping for effect.
Why: Cooling is half the practice; the other half is the extended exhale, which is the reliable lever for shifting the nervous system toward rest. Sitali gives you both in one move.
When to actually use it
- Hot days and hot rooms. This is its home turf. Five rounds before practice on a summer afternoon, or after coming in from the heat, takes the edge off in a way that feels disproportionate to the effort. Our cooling breaths overview places it alongside its cousins.
- Hot emotions. The tradition prescribes sitali for anger, and the logic is not mystical: you cannot sip air slowly through a rolled tongue while yelling. The practice imposes a pause, and the pause imposes perspective. It is a circuit breaker you carry in your mouth.
- After heating practices. If you have been doing vigorous sun salutations or a heating pranayama like bhastrika, a few rounds of sitali are the classical counterweight — the breath equivalent of the cooldown lap.
- Before sleep in summer. Overheated and irritable is a poor entry into sleep. Five rounds, seated on the bed, then lie down. See also the broader summer practice guide for adjusting the rest of your routine to the season.
What it will not do
Honesty section, as always: sitali lowers how hot you feel and settles agitation. It does not meaningfully lower core body temperature, and it is not a treatment for heat exhaustion — actual overheating is a medical situation requiring water, shade, and sometimes a doctor, not a breathing technique. The classical texts also claim it cures hunger and thirst; the modern reader can file that under "tradition being enthusiastic." You will still want lunch.
Similarly, if you live somewhere cold and it is January, this is not your practice — the tradition is explicit that cooling breaths suit hot weather and hot constitutions, and common sense agrees. Bookmark it for the heat.
Roll the tongue or hiss through the teeth — either way, you are carrying a small, portable shade tree. Five slow sips of cooled air, five long nasal exhales, and the summer afternoon loses its grip. The bee gets all the fame, but in August, the straw wins.
