Right now, without changing anything, notice your face. Is your jaw clenched? Are your teeth touching? Is your tongue pressed hard against the roof of your mouth? Are your eyebrows slightly furrowed? If you answered yes to any of these, you are carrying tension in your face, and you have probably been carrying it all day without knowing it.
Facial tension is the stress nobody talks about. We discuss shoulder tension, back pain, and tight hips, but the face holds an extraordinary amount of unconscious stress. Jaw clenching (bruxism) affects an estimated 10-15% of adults. Chronic forehead tension contributes to tension headaches. Throat tightness restricts the voice and contributes to a feeling of being choked or unable to speak. All of this tension is invisible to others and often invisible to the person carrying it until it causes pain.
Lion's breath (simhasana pranayama) is the antidote. It looks absolutely ridiculous, open your mouth as wide as possible, stick out your tongue, widen your eyes, and exhale forcefully with a "haaa" sound, and that is exactly why it works. It forces every muscle in your face, jaw, and throat to stretch and release simultaneously, breaking the patterns of chronic tension that accumulate throughout the day.
If you can do lion's breath without laughing, you are not doing it with enough commitment. The absurdity is part of the medicine.
How do you practice lion's breath?
You practice lion's breath by inhaling through the nose, then exhaling forcefully through a wide-open mouth with the tongue stretched out and down while the eyes open wide.
The Basic Technique
- Sit comfortably, either on your heels (kneeling) or cross-legged. You can also do this in a chair.
- Place your hands on your knees with fingers spread wide.
- Inhale deeply through your nose. As you inhale, lift your chest and lengthen your spine.
- At the top of the inhale, open your mouth as wide as possible. Stick your tongue out and down toward your chin. Open your eyes wide and look up toward the point between your eyebrows.
- Exhale forcefully through your mouth with a loud "haaa" sound from the back of your throat. The exhale should be audible and energetic.
- Feel the stretch across your entire face: jaw, cheeks, tongue, eyes, forehead.
- Close your mouth and return to normal breathing for two to three breaths.
- Repeat three to five times.
Getting the Sound Right
The exhale sound comes from the back of your throat, similar to the sound you make when fogging a mirror, but louder and more forceful. It is not a scream. It is not a whisper. It is a controlled, open-throated release that engages the muscles of the throat and larynx. Think of a lion roaring, but at indoor volume.
Why does lion's breath work?
Lion's breath works by forcing every muscle in the face, jaw, and throat to stretch and release at once, breaking the chronic tension patterns that build up during the day.
Forced Release of Held Patterns
Your face has 43 muscles, and most of them are locked in habitual tension patterns that you never consciously activate or release. Lion's breath forces an extreme stretch across all of them simultaneously. The wide-open mouth stretches the muscles that clench your jaw. The extended tongue stretches the throat and the muscles under the chin. The wide eyes counteract the chronic squinting from screen use. The overall effect is a full facial reset.
Vagus Nerve Stimulation
The forceful exhale with vocalization stimulates the vagus nerve, which runs through the throat. The open-throat position combined with the sound creates vibration that travels along the vagal pathway, promoting parasympathetic activation and a sense of calm that follows the initial energetic release. The broader breathwork literature supports this vagal effect. A 2018 systematic review in Frontiers in Human Neuroscience defined slow breathing as fewer than 10 breaths per minute and concluded it increases heart rate variability and parasympathetic activity while easing anxiety and arousal.
Emotional Release
There is a psychological component to lion's breath that is hard to quantify but easy to experience. The act of making yourself look deliberately silly, of opening your mouth wider than social norms allow, of sticking out your tongue and making noise, breaks through inhibition and self-consciousness. Many people report feeling lighter, freer, and more emotionally open after a few rounds, particularly if they tend to suppress emotions or maintain a controlled exterior. Lion's breath is built around a big, forceful exhale, and long-exhale breathing has measurable mood effects. In a 2023 study in Cell Reports Medicine, 5 minutes of daily breathwork for 1 month improved mood and lowered respiratory rate more than mindfulness meditation, with exhale-focused cyclic sighing producing the largest mood gains across the 108 enrolled adults.
When should you use lion's breath?
Use lion's breath whenever facial or jaw tension builds: after long screen sessions, before speaking or performing, during moments of stress, and before bed.
After Prolonged Screen Time
Screen use promotes jaw clenching, eyebrow furrowing, and forward head posture. Three rounds of lion's breath after every hour of screen time reverses these patterns. It takes thirty seconds and feels dramatically better than continuing to hold the tension.
Before Public Speaking or Performance
Lion's breath releases the throat tension that restricts vocal quality and volume. Singers, speakers, and actors use it as a warm-up because it opens the throat, relaxes the jaw, and energizes the face. Do three to five rounds backstage or in the bathroom before your moment arrives.
During Stress or Frustration
When you feel tension building in your face and jaw (which happens before you consciously register it as stress), lion's breath provides an immediate release valve. It is the facial equivalent of shaking out your arms after carrying heavy bags. The wider evidence for breathwork as a stress tool is encouraging. A 2023 Scientific Reports meta-analysis of 12 randomized trials with 785 adults found breathwork produced a small-to-medium reduction in self-reported stress (Hedges g = -0.35) versus control conditions.
Before Bed
If you clench your jaw during sleep (grinding teeth is common), doing five rounds of lion's breath before bed can release the tension that predisposes you to clenching. Combine with jaw massage: press your fingers into the masseter muscles (the large muscles at the angle of your jaw) and make small circles while breathing slowly through your nose.
Variations
Lion's Breath with Movement
From a kneeling position, inhale and arch your back slightly (cow position in yoga). As you exhale with lion's breath, round your back and tuck your chin before opening into the full expression. This adds a spinal release to the facial release.
Quiet Lion's Breath
If you are in a setting where the full roar is not appropriate, do a silent version. Same mouth position, same tongue extension, same wide eyes, but exhale silently. You lose the vagal stimulation from the vocalization but retain the muscular release. This version works at your desk without alarming coworkers.
Lion's Breath Sequence
Combine lion's breath with other facial releases for a complete tension protocol.
- Three rounds of lion's breath.
- Ten seconds of exaggerated chewing motion (open and close your jaw widely).
- Ten seconds of facial scrunching (squeeze your whole face tight, then release).
- Two more rounds of lion's breath.
- Thirty seconds of gentle jaw circles (open your mouth slightly and make slow circles with your lower jaw).
Common Mistakes
- Being too gentle defeats the purpose. Lion's breath is not a polite technique. Go big. Open your mouth wider than feels comfortable. Stick your tongue out farther than feels normal. Make the sound louder than feels appropriate. The exaggeration is the mechanism.
- Holding your breath before the exhale creates unnecessary tension. The transition from inhale to exhale should be smooth: inhale through the nose, open the mouth, and exhale immediately without pausing.
- Doing it in front of a mirror (for beginners) often causes self-consciousness that limits the expression. Close your eyes during the exhale if the visual of your own lion face inhibits you. Once you are comfortable with the technique, the mirror can be useful for checking your form.
- Skipping the eye component loses part of the release. The wide-open eyes counteract the chronic tension in the forehead and around the eyes. Make sure you are actively widening your eyes, not just opening your mouth.
Lion's Breath and the Five Pillars
Recovery Pillar
Facial tension contributes to headaches, jaw pain, and poor sleep (through teeth grinding). Releasing this tension through lion's breath supports recovery from both training and daily stress by removing a chronic tension pattern that drains energy and disrupts rest.
Mind Pillar
The willingness to look silly, to break social norms, to make a loud sound in a quiet room, is a form of mental practice. Lion's breath challenges inhibition and self-consciousness, two barriers that limit personal growth far beyond breathing exercises.
Movement Pillar
Jaw and facial tension restrict neck mobility and contribute to forward head posture. Releasing this tension through lion's breath improves neck range of motion and supports better posture, which in turn supports better breathing mechanics. The cycle is self-reinforcing in the best way.
At ooddle, we include lion's breath in protocols as a tension release practice because it addresses a category of stress that most wellness programs completely ignore. Your face is part of your body. It holds stress, creates pain, and affects your posture, your breathing, and your emotional expression. Lion's breath is not dignified, but it is effective. And between dignity and effectiveness, we will choose effectiveness every time.
