Left-Nostril Moon Breath
A slow, one-nostril breathing practice that quiets the body and cools an overactive mind before you try to sleep on it.
Why it works
Breathing only through the left nostril has shown up in physiology studies tied to a relative shift toward parasympathetic dominance, with modest drops in heart rate and blood pressure. The slow, low-effort nasal airflow keeps your breathing rate down and points the whole system toward a settled, cooling state built for winding down. Nasal-only breathing also forces gentle, unforced airflow, which crowds out the shallow over-breathing that pre-sleep anxiety loves to produce.
Left-nostril breathing, chandra or moon breathing in the yoga tradition it comes from, has been linked to lower heart rate and blood pressure and a shift toward parasympathetic activity compared with right-nostril or ordinary two-nostril breathing. Modest effects, consistent direction.
- Rhythm
- 4 · 6 seconds, at 6 breaths a minute
- Tone
- 174 Hz. The lowest of the solfeggio tones, kept for rest, which is lineage rather than physiology.
How to practice
- Sit or lie on your right side, which naturally opens up the left nostril.
- Use your right thumb to gently close the right nostril.
- Inhale slowly and quietly through the left nostril for a count of about 4.
- Exhale slowly through the same left nostril for a count of about 6, keeping the right nostril closed.
- Continue breathing only through the left nostril for 5 to 8 minutes.
- When you're done, drop the hand and let both nostrils breathe naturally while you drift off.
- Keep the airflow so soft it's nearly silent. If you can hear it, ease off.
- Each exhale runs a touch longer than the inhale.
- Relax the jaw, the shoulders, and the hand doing the work. It doesn't need to grip that hard.
⚠ If the left nostril is congested, save this practice for when it clears rather than forcing airflow.
