Simhasana, known in English as Lion's Breath, is one of the oldest and most physically expressive yoga breathing techniques. You stick out your tongue, exhale forcefully with a sound, and look up. People feel silly the first time. They also feel calmer immediately afterward. Here is why it works and how to do it.
The Science Behind Lion's Breath
Simhasana works on three systems at once. The forceful exhale activates the parasympathetic nervous system. The wide opening of the mouth and tongue stretch the throat and face muscles, where chronic tension hides. The vibration of the sound stimulates the vagus nerve.
The combination releases held tension in the jaw, neck, and shoulders, areas that hold most of our chronic stress. People with TMJ or grinding habits often find it especially helpful.
Why the Roar Matters
The sound is not for show. The vibration travels through the throat and stimulates vagal fibers. Silent versions of the breath work less effectively. The bigger and more ridiculous the roar, the more release.
How to Do It (Step by Step)
- Sit comfortably with your spine tall, either cross-legged or in a chair.
- Place your hands on your knees with your fingers spread wide like claws.
- Inhale deeply through your nose, filling your belly first, then chest.
- Open your mouth wide, stick your tongue out and down toward your chin.
- Look upward, toward the space between your eyebrows.
- Exhale forcefully through your mouth with a long "haaa" sound, like a roar.
- Empty your lungs completely. Then close your mouth and breathe normally for 2 breaths.
- Repeat 3 to 5 times total. Stop if you feel lightheaded.
Common Mistakes
Holding back the sound. The vibration is the point, do it where you can be loud or do it in your car. Tightening the jaw, the whole face should relax into the exhale. Skipping the eye gaze, looking up adds a stretch through the front of the neck that releases more tension. Doing too many in a row, 5 is plenty.
- Be loud if you can. The vibration drives the effect. Whisper versions work less.
- Stretch the tongue fully. Down toward the chin, not just out. The face release is in the tongue extension.
- Soften the eyes. Eyes look up but stay relaxed. No squinting.
- Use it for jaw tension. If you grind or clench, this is your breath.
When to Use Lion's Breath
After a difficult conversation, to release facial tension. Before public speaking, to loosen the jaw. In the morning if you wake with a tight face from clenching. After long screen sessions, where the jaw and neck stiffen. As a reset between meetings if you have privacy.
Avoid it in public unless you are willing to look strange. The technique loses power when you mute the sound.
