What is Shitali Cooling Breath?
Shitali (also transliterated as Sitali) is a pranayama technique in which the practitioner inhales through either a rolled tongue or pursed lips, drawing air across the moistened surface to create an evaporative cooling effect. The cooled air is then retained briefly before being exhaled through the nose. The practice is distinguished by its physiological effect—practitioners typically report a tangible cooling sensation in the mouth, throat, and eventually throughout the body. Shitali is classified among the eight classical pranayamas and is specifically prescribed in yogic texts for reducing excess heat (pitta in Ayurvedic terms), calming anger or agitation, and preparing the body for meditation.
Origins & Lineage
Shitali appears in the Hatha Yoga Pradipika (circa 15th century CE), one of the foundational texts of hatha yoga composed by Swami Swatmarama. In Chapter 2, verses 54-56, the text describes the technique: drawing in air through the tongue, holding the breath, and then exhaling through the nostrils. The practice is presented alongside other pranayamas including bhastrika, ujjayi, and bhramari, positioning it within a systematic approach to breath control designed to purify the nadis (energetic channels) and prepare the practitioner for deeper meditative states.
The Gheranda Samhita (late 17th century), another core hatha yoga text, also describes Shitali, noting its capacity to satisfy hunger and thirst—a claim likely rooted in the practice’s effect on the autonomic nervous system and its ability to shift the body into a parasympathetic state. While these texts provide the earliest written documentation, oral transmission within yogic lineages likely predates the manuscripts by centuries. The technique has been preserved and taught within multiple yoga traditions, including Iyengar, Sivananda, and Kundalini yoga schools.
How It’s Practiced
The classical method involves sitting in a comfortable, upright position—typically sukhasana (easy pose) or padmasana (lotus pose)—with the spine erect and shoulders relaxed. The practitioner extends the tongue slightly beyond the lips and curls the lateral edges upward to form a tube or straw-like channel. Not all individuals possess the genetic ability to roll their tongue in this manner; estimates suggest 65-80% of people can perform the roll, with significant variation across populations.
For those unable to roll the tongue, an alternative method involves slightly parting the teeth and pursing the lips, inhaling through the small opening. This variation, while technically distinct from the classical Sitkari pranayama (which involves inhaling through clenched teeth), produces a similar cooling effect and is often taught as an accessible modification.
Once the tongue or lips are positioned, the practitioner inhales slowly and steadily through the opening, consciously noting the cooling sensation. The inhalation is typically deep but not forced. After a comfortable inhalation, the tongue is drawn back into the mouth, the lips close, and the breath is held briefly (kumbhaka) for 2-5 seconds. The exhalation follows slowly through both nostrils. A typical session involves 5-20 rounds, though advanced practitioners may extend the practice.
Shitali Cooling Breath Today
Shitali has gained recognition beyond traditional yoga studios as interest in breathwork and nervous system regulation has expanded. It appears in contemporary yoga teacher training curricula, mindfulness-based stress reduction (MBSR) protocols adapted for heat management, and online platforms offering guided pranayama sequences. Teachers often prescribe Shitali for students dealing with hot flashes, summer heat, or conditions associated with excess “heat” in both literal and metaphorical senses—inflammation, anger, or hyperarousal states.
The practice is featured in retreats focused on Ayurvedic principles, where it’s paired with cooling foods and lifestyle recommendations for balancing pitta dosha. Kundalini yoga classes, following the teachings systematized by Yogi Bhajan, frequently incorporate Shitali as part of kriyas (exercise sets) designed to cool the body after vigorous movement or breath of fire sequences. The technique has also been examined in preliminary scientific research investigating its effects on blood pressure, heart rate variability, and subjective measures of thermal comfort.
Common Misconceptions
Shitali does not lower core body temperature to a degree that would be measurable with standard thermometry in most individuals; the “cooling” is primarily a localized sensory experience and an autonomic shift rather than a significant thermogenic change. While traditional texts claim the practice can eliminate hunger and thirst, these statements reflect pre-modern understandings of physiology and should not be interpreted as substitutes for nutrition or hydration.
The practice is sometimes conflated with Sitkari, a related but distinct technique that involves inhaling through clenched teeth rather than a rolled tongue. While both produce cooling effects, the mechanisms and sensations differ. Additionally, Shitali is not appropriate for individuals with asthma, chronic bronchitis, or excessive mucus production, as the cooling effect may exacerbate these conditions. It is also contraindicated in very cold environments or for individuals with excess kapha (cold, heavy qualities in Ayurvedic assessment).
How to Begin
For those new to Shitali, begin with 5-8 rounds in a seated position during a cool or temperate part of the day. Pay attention to the sensation of temperature change during inhalation and notice any shifts in mental state or overall comfort. The Light on Pranayama by B.K.S. Iyengar provides detailed instructions and contraindications. The Bihar School of Yoga’s Asana Pranayama Mudra Bandha offers a systematic approach to integrating Shitali within a broader pranayama practice.
For direct instruction, seek teachers trained in traditional hatha yoga lineages—Iyengar, Sivananda, or Satyananda traditions typically include thorough pranayama training. Many studios offer pranayama-specific workshops or courses separate from asana classes, providing a more focused environment for learning breath techniques. Online platforms such as Yoga International and Glo feature instructional videos from experienced teachers. When beginning, practice on an empty stomach and avoid forcing the breath; the cooling effect should feel pleasant, not uncomfortable or straining.
