What is Breathing Exercise 4-7-8?

The 4-7-8 Breathing Exercise guides you through a calming pattern: inhale through the nose for 4 seconds, hold the breath for 7, exhale through the mouth for 8. The technique was popularised by Dr Andrew Weil and is rooted in pranayama. Your session data stays on the device.

Tap a pattern preset (4-7-8, Box, Coherence, or Triangle) or set your own inhale, hold, and exhale seconds, choose how many cycles you want, then press start. The visual fills during inhale, stays steady through the hold, and eases back down during the exhale, and you can switch the look between a circle, rings, or a rising wave. For the classic 4-7-8 method the 1:1.75:2 ratio is what slows the heart rate, so try not to shorten the eight-second out-breath even if it feels long at first.

How to use

1. Press start to begin the guided breathing session
2. Follow the visual cues: breathe in, hold, breathe out
3. Complete a few rounds for the best results

When to use

• Lying down at night when your mind is racing and sleep is not coming.
• Five minutes before a stressful meeting, interview, or phone call.
• After a panic spike when you need to bring the heart rate back down.

Result

Practice 4 rounds of the 4-7-8 technique before bed to help you fall asleep faster.

FAQ

Why does the exhale have to be eight seconds long?

The long out-breath is what triggers the parasympathetic nervous system, which is the part that slows your heart and relaxes muscles. A short inhale and a much longer exhale shifts the balance away from fight-or-flight. Cutting the exhale short reduces the effect.

I can't hold my breath for seven seconds. What should I do?

Keep the 4:7:8 ratio but shrink everything by half: try 2 seconds in, 3.5 hold, 4 out. After a week or two your lung control improves and you can work up to the full count. The ratio matters more than the absolute seconds.

How many rounds should I do per session?

Dr Weil's original guidance is four cycles, twice a day, for the first month, then up to eight cycles per session once you are used to it. Doing more than eight in a row can make you lightheaded because of the extended holds.

Is it safe if I have asthma or a respiratory condition?

The seven-second hold can feel uncomfortable for people with asthma or COPD. Check with your doctor before adding it to a routine. A shorter hold (3 or 4 seconds) is usually fine and still gives most of the calming effect.

Should I breathe through my nose or my mouth?

Nose for the inhale, mouth for the exhale, with the tip of the tongue resting behind the upper front teeth. The pursed-lip exhale slows the airflow and is part of why the technique reduces anxiety symptoms quickly.
