Breathe in for 4, hold for 7, breathe out for 8. The orb breathes, you follow. Free, no sign-up, no cookies.
Ready?
Breathe all the way out first
in 4 · hold 7 · out 8
If anything feels uncomfortable, just stop and breathe normally.
How it works
- Sit comfortably or lie down. If you want to close your eyes, turn on the sound.
- Breathe all the way out through your mouth once.
- Breathe in quietly through your nose while the orb grows: 4 seconds.
- Hold your breath gently while the orb stays big: 7 seconds.
- Breathe out through your mouth with a whoosh while the orb shrinks: 8 seconds.
That’s one round, and it takes 19 seconds. One minute is plenty to start. Then just breathe normally.
Only hold your breath as long as it feels easy, never until you’re gasping for air. Never practice breath holds in or near water (including the bathtub), while driving, or anywhere a brief blackout could be dangerous. If you feel dizzy or notice tingling in your hands or lips, stop and breathe normally. If you’re pregnant or have a heart or circulation condition, high blood pressure, epilepsy, glaucoma, or panic disorder, skip longer breath holds or check with your doctor first.
If the hold feels too long
Seven seconds of holding feels long to many people at first. That’s what Find your breathing pace is for: you tap four times as you breathe in. The orb starts at your own pace and then slows down until you reach six breaths a minute. The shape stays the same: a short inhale, a longer hold, the longest exhale. All three phases get shorter in the same proportion. Never hold until you gasp for air.
What studies show
So far, studies have mostly measured what happens in the body right after the exercise. In 43 healthy young adults, heart rate was lower after three sets of six rounds.1 In a comparison with 84 college students, six breaths a minute raised heart rate variability more than 4-7-8 did; none of the exercises had a meaningful effect on blood pressure or mood in the lab.2 Both studies tested the technique, not the nowa app.
I haven’t found a study that measures whether 4-7-8 helps you fall asleep faster. It’s a pleasant structure for your evening, not a proven sleep hack. More on this, including where the method comes from: 4-7-8 breathing: how to do it, and what it actually does.
