Lion's Breath
How to Practice Lion's Breath
In short
Inhale deeply for 4 seconds, exhale forcefully with a "ha" sound for 3 seconds, rest for 2 seconds.
Step by step
- Kneel on the floor in Vajrasana (thunderbolt pose), with your hips resting on your heels and the tops of your feet flat on the ground. If kneeling is uncomfortable, sit cross-legged on a cushion or upright in a chair. Place your palms firmly on your knees with your fingers spread wide, pressing gently into the kneecaps.
- Sit tall and take a moment to center yourself. Lengthen your spine, roll your shoulders back and down, and relax your face. Let go of any tension in your jaw, forehead, and around your eyes. Take one or two natural breaths to settle in.
- Inhale deeply through your nose for four seconds. Close your mouth and draw a slow, full breath in through both nostrils. Fill your belly first, then your ribcage, then your upper chest. Feel your torso expand in all directions.
- Open your mouth wide and extend your tongue. At the peak of the inhale, open your mouth as wide as you comfortably can. Stretch your tongue out and down toward your chin — reach as far as you can without straining. Simultaneously, widen your eyes and direct your gaze upward toward the space between your eyebrows (this eye position is known as Shambhavi Mudra in yoga).
- Exhale forcefully with a "haaaa" sound for three seconds. Contract your abdominal muscles and push the breath out through your open mouth, producing a strong, audible "ha" sound from the back of your throat. The exhale should feel like a powerful, controlled roar — not a scream, but a deep, resonant release. At the same time, spread your fingers wide like the extended claws of a lion.
- Rest for two seconds. Close your mouth, relax your facial muscles, and breathe naturally through your nose. Notice the sensations in your face, jaw, throat, and chest. Feel the release of tension and the warmth in your throat.
- Repeat for five to seven rounds. Each cycle of inhale, roar, and rest takes approximately nine seconds. Five to seven rounds will complete the practice in about three minutes. After the final round, sit quietly with your eyes closed for 30 seconds, observing how your face, throat, and body feel.
Origin and History
Lion's Breath, known in Sanskrit as Simhasana (from "simha," meaning lion), is one of the oldest named asanas in the yoga tradition. The pose and its associated breathing technique are described in the Hatha Yoga Pradipika, the fifteenth-century foundational text on hatha yoga written by Yogi Swatmarama. In that text, Simhasana is listed as one of the most important asanas and is described as "the destroyer of all diseases." The full traditional form involves a specific seated posture (with one ankle crossed over the other and the perineum pressed against the heels) combined with the forceful breath and lion's expression. The Gheranda Samhita, another classical hatha yoga text from approximately the same period, also describes Simhasana and emphasizes its purifying effects on the throat and its capacity to destroy disease.
Beyond the yoga tradition, forceful expiratory techniques with vocalization appear across many cultures. In Japanese martial arts, the kiai — a short, powerful shout delivered during a strike — serves a similar physiological function: it engages the diaphragm, stabilizes the core, and produces a sudden parasympathetic rebound after the burst of sympathetic activation. The Maori haka, a ceremonial war dance of the indigenous New Zealand people, features wide eyes, extended tongue, and forceful vocalizations that closely mirror the physical components of Simhasana. In Kundalini yoga, as taught by Yogi Bhajan in the twentieth century, Lion's Breath is frequently incorporated into kriya sequences designed to release anger, clear the throat chakra (Vishuddha), and stimulate the thyroid and parathyroid glands through the extreme neck and throat extension. The technique's appearance across disparate cultures suggests that the human body has an innate mechanism for releasing tension and emotional charge through forceful vocalized exhalation — a mechanism that Simhasana formalizes into a repeatable, therapeutic practice.
Scientific Research and Benefits
While Lion's Breath has not been studied as extensively in clinical trials as some quieter breathing techniques, the physiological mechanisms underlying its benefits are well understood. The forceful exhale activates the diaphragm and abdominal muscles, producing a temporary increase in intrathoracic pressure followed by a rapid drop — a pattern that stimulates the vagus nerve and triggers a parasympathetic rebound. This is the same mechanism behind the Valsalva maneuver, which is used clinically to stimulate vagal tone. The vocalization component adds further vagal stimulation: research published in the International Journal of Yoga in 2018 demonstrated that breathing techniques involving vocalization (such as chanting or audible exhales) produce greater increases in heart rate variability compared to silent breathing at the same rate, suggesting that the vibratory stimulation of the larynx and pharynx directly activates vagal afferent fibers in the throat.
The extreme facial expression involved in Lion's Breath provides measurable benefits for the muscles of the face and jaw. The masseter, one of the strongest muscles in the body by weight, frequently holds chronic tension in people who experience stress, anxiety, or temporomandibular dysfunction. Opening the mouth wide and extending the tongue stretches the masseter, the temporalis muscles at the temples, and the medial and lateral pterygoid muscles deep in the jaw. A 2016 study in the Journal of Physical Therapy Science found that jaw-opening exercises similar to those in Simhasana reduced pain and improved range of motion in patients with temporomandibular disorders. The tongue extension simultaneously stretches the suprahyoid and infrahyoid muscles of the throat, which can become tight from prolonged sitting, forward head posture, or habitual throat tension during stress.
From a psychological perspective, Lion's Breath engages the body's natural mechanisms for emotional release. The connection between vocal expression and emotion processing is well-documented in neuroscience: the motor cortex areas controlling the face, tongue, and larynx are densely connected to limbic structures including the amygdala and insula, which process emotions. By deliberately activating these motor patterns in a safe, controlled context, practitioners may facilitate the processing and release of stored emotional tension. Music therapists and somatic psychotherapists have long used vocalization exercises that parallel Lion's Breath for clients with difficulty expressing or releasing anger, frustration, and grief. The playful, permission-giving nature of "roaring like a lion" can also reduce psychological inhibition and self-consciousness, which many practitioners report as therapeutic in itself.

Tips and Variations
- Vary the intensity. You can practice Lion's Breath at different intensities depending on your setting and needs. In a yoga class, commit to a full, powerful roar. At your desk, a strong whispered exhale with the facial expression will still release tension effectively.
- Try it in tabletop position. For a more dynamic variation, start on hands and knees (tabletop pose). On the exhale, arch your back like a cat while roaring. This adds a spinal extension component and opens the chest further.
- Direct the gaze. Traditionally, the gaze is directed upward toward the third eye point (Shambhavi Mudra). An alternative is to cross the eyes and gaze at the tip of the nose (Nasagra Drishti). Both eye positions intensify the facial muscle engagement and draw attention inward.
- Combine with other practices. Lion's Breath works well as an energizing warm-up before meditation, as a mid-practice reset during a yoga sequence, or as a standalone tension-relief exercise during a work break.
- Practice with children. Lion's Breath is one of the most engaging breathing exercises for children because it involves making silly faces and loud sounds. Use it to help children process frustration, transition between activities, or simply burn off excess energy in a structured way.
- Target jaw and throat tension specifically. If you carry tension in your jaw (from clenching or grinding) or throat (from tension when speaking), practice two to three rounds of Lion's Breath every few hours throughout the day. The accumulated effect of regular jaw and tongue stretching can significantly reduce chronic facial tension over time.
- Alternate with calming breaths. After a round of Lion's Breath, follow with a few cycles of slow, quiet breathing to balance the energizing effect. This combination of activation followed by calm creates a complete nervous system reset.
Frequently Asked Questions
Yes. While the forceful vocalized exhale is a core part of the traditional technique, you can modify it for quiet environments. Exhale through an open mouth with a strong but whispered "haaaa" sound, or simply exhale forcefully without vocalization while maintaining the wide-mouth, extended-tongue facial expression. The physical stretching of the jaw, tongue, and throat muscles still provides significant tension release even without the full roar. The vibration from vocalization does add vagal stimulation, so when you have the opportunity to practice with full sound, take advantage of it.
Lion's Breath can be very effective for relieving jaw tension and is sometimes recommended as part of a self-care protocol for temporomandibular joint (TMJ) dysfunction. The wide opening of the mouth stretches the masseter and temporalis muscles, which are the primary muscles that become chronically tight in people who clench or grind their teeth. The tongue extension stretches the floor of the mouth and the suprahyoid muscles. If you have an active TMJ flare-up or acute jaw pain, open your mouth only to a comfortable width and avoid extreme extension. For chronic tension, practicing two to three gentle rounds several times per day can gradually reduce baseline jaw tightness.
A standard practice session consists of five to seven rounds, which takes approximately three minutes. For quick tension relief during the day, even two to three rounds can provide noticeable benefit. Avoid doing more than ten to twelve rounds in a single session, as the forceful exhale can occasionally cause lightheadedness if overdone, particularly in people who are sensitive to changes in blood pressure or carbon dioxide levels. Always return to natural breathing between rounds and stop if you feel dizzy, lightheaded, or strained.
Lion's Breath is one of the most child-friendly breathing exercises available. Children are naturally drawn to the playful, expressive nature of making a lion face and roaring. Pediatric yoga instructors, child psychologists, and elementary school teachers frequently use Lion's Breath to help children release frustration, manage anger, process big emotions, and transition between activities. It can be introduced to children as young as three or four years old. For younger children, focus on the fun and imaginative aspect rather than precise technique, and keep sessions short — two to three rounds is plenty. Many children enjoy doing it in a group setting, which can reduce self-consciousness and increase engagement.
Avoid Lion's Breath if you have a recent injury to the face, jaw, neck, or throat that could be aggravated by the wide mouth opening and forceful exhalation. People with active throat infections, laryngitis, or who have recently undergone throat or dental surgery should wait until fully recovered. If you have uncontrolled high blood pressure, the forceful exhalation produces a temporary spike in intrathoracic pressure that may not be advisable — consult your doctor. Those with knee problems should choose a seated position (chair or cross-legged) rather than kneeling. As with all breathing practices, if you experience dizziness, pain, or significant discomfort, stop the practice and breathe normally.
