Unlike most yoga breathing techniques that inhale through the nose, Sitali and Sitkari draw air in slowly through the mouth across moist tongue surfaces (producing evaporative cooling) and exhale quietly through the nose. If you cannot roll the sides of your tongue into a tube for Sitali, Sitkari—inhaling softly across lightly parted teeth with the tongue tip behind the incisors—offers the exact same cooling effect.
The mechanism: Passing a thin stream of air over saliva on the tongue evaporates moisture, cooling the oral mucosa before you close the mouth and exhale nasally.
Sitali vs. Sitkari: Sitali uses a lengthwise curled tongue tube; Sitkari rests the tongue flat behind lightly touching teeth.
Environmental rule: Because mouth inhalation bypasses nasal filtering and warming, practice only in warm, clean, dust-free air.
When to avoid: Skip both techniques in cold winter air, high pollen/pollution, active asthma or bronchitis, or sensitive dental enamel.
Why These Two Breaths Inhale Through the Mouth and Exhale Through the Nose
In nearly every other Hatha yoga posture and pranayama practice, you inhale through the nostrils so the nasal turbinates warm, humidify, and filter incoming air. `Sitali` ("cooling") and `Sitkari` ("sipping/hissing") deliberately reverse the entry path for short sessions during warm weather or after heated physical exertion.
When you draw a slow, narrow stream of air across the wet surface of the tongue, phase-change evaporation cools the moisture film on the tongue and palate, creating an immediate sensory impression of coolness. At the top of the inhalation, you draw the tongue back inside, close the lips, pause briefly to let the air warm in the upper airway, and exhale slowly through both nostrils. In traditional Ayurvedic and Hatha frameworks (`Hatha Yoga Pradipika` Chapter 2), both breaths are classified as Pitta-pacifying (`doshaPitta < 0`) and suited to midday or summer (`grishma`/`sharad`) practice.
- Step 1 (Inhale — 4 seconds): Draw air smoothly across the moist tongue surface without straining the neck or facial muscles.
- Step 2 (Close & transition — 1 second): Retract the tongue, close the lips, and swallow if your mouth feels dry.
- Step 3 (Exhale — 4 to 6 seconds): Breathe out quietly and evenly through both nostrils.
Sitali vs. Sitkari: Solving the Tongue-Rolling Constraint
About 20% to 35% of adults cannot curl the lateral edges of their tongue upward into a U-shaped tube—an anatomical variation in intrinsic lingual muscle control. Trying to force a tongue curl tenses the jaw, floor of the mouth, and hyoid muscles, defeating the purpose of a calming breath.
`Sitkari` is the classical companion technique designed for anyone who cannot (or prefers not to) curl the tongue. To practice Sitkari, bring the upper and lower teeth lightly together (or leave a 1-millimeter gap), part the lips slightly, rest the tip of the tongue gently behind the front teeth, and sip the inhale across the sides of the tongue with a soft "see" sound before closing the mouth and exhaling through the nose.
- Choose Sitali when: Curling the sides of the tongue into a tube feels effortless and your jaw stays completely relaxed.
- Choose Sitkari when: Your tongue does not curl into a tube, or protruding the tongue dries out the tip too quickly.
- Sadamta variation: If cold air across the front incisors triggers tooth sensitivity, curl the tongue tip back against the hard palate (`Kaki Mudra` / pursed-lip sip) to shield the front teeth.
Air Quality, Temperature, and Respiratory Precautions
Because inhaling through the mouth bypasses the nasal hair (`vibrissae`) and mucosal filtration system, air enters the pharynx cooler, drier, and unfiltered. In cold, dry environments or rooms with dust, smoke, fragrance, or high pollen counts, oral inhalation can irritate the throat and trigger bronchoconstriction in people with reactive airways or exercise-induced asthma.
Keep sessions brief—typically 5 to 10 rounds taking 1 to 2 minutes total—and take a sip of room-temperature water before and after if your mouth feels dry. In the `Ayurveda & Asana Yoga` app, you can filter the `Practices` library by the `Pranayama` (`Breath`) chip and check each practice's `season`, `timeOfDay`, and `contraindications` before starting.
- Warm-room rule: Practice Sitali or Sitkari only in a warm, clean indoor space or mild outdoor shade—never in cold winter wind or dusty air.
- Respiratory sensitivity: Skip oral-inhalation breaths if you have a sore throat, active cough, sinus infection, or cold-air-triggered asthma.
- Hydration check: Stop after 5 to 8 rounds if the tongue surface dries out; forcing dry air over a parched tongue irritates the oral mucosa.
Frequently Asked Questions
Does Sitali actually lower core body temperature during a fever?
Sitali cools the wet mucosa of the tongue and mouth through local evaporation and promotes calm parasympathetic pacing, but it is a comfort and relaxation practice—not a medical treatment for fever or heatstroke.
How many rounds of Sitali or Sitkari should I practice after a warm yoga session?
Five to nine slow rounds (about 60 to 90 seconds) seated comfortably after your standing postures—before lying down for Savasana—is plenty to cool the mouth and slow your breathing rate.
What should I do if Sitkari makes my front teeth feel sensitive?
Instead of drawing air between the teeth, purse your lips into a small "O" as if sipping through a narrow straw while keeping the tongue flat inside the mouth, then exhale through the nose.
