How does the 4-7-8 breathing technique work?

You inhale through the nose for four counts, hold for seven, and exhale through the mouth for eight. The exhale is about twice as long as the inhale, and that longer out-breath is what tips the body from alert toward rest. The seven-count hold makes the ratio easy to hold on to without speeding up.

How long does it take to fall asleep with 4-7-8 breathing?

There is no reliable number, and anyone quoting one is guessing. What is fair to say is that it is a sleep-onset routine rather than a switch: most people use four rounds as a wind-down after the lights are off, and it tends to work better as a nightly habit than as a one-off rescue.

How many times a day should I do 4-7-8 breathing?

Four rounds at a time, once or twice a day, is the usual guidance while you are learning it. Because the hold and the long exhale are demanding, doing many more rounds in one sitting can leave you lightheaded rather than calmer.

Which is better, box breathing or 4-7-8?

They do different jobs. Box breathing (4-4-4-4) is even and steadying, which suits the moments before something demanding, when you want to stay sharp. 4-7-8 is weighted toward the exhale, which brings you down, so it suits sleep. You can try both on this site and see which one your body prefers.

Is 4-7-8 breathing safe?

For most healthy adults, yes, in short sessions. Stop if you feel dizzy or faint, and breathe normally for a minute. If you are pregnant, have a respiratory or heart condition, or are being treated for anxiety, ask a clinician before making it a routine. Braele is a wellness app, not a medical device.

4-7-8 breathing

4 · 7 · 8

Inhale for four, hold for seven, exhale for eight. The long exhale is what settles the body, which is why this one belongs in bed with the lights out. Start it below and breathe along.

Why the long exhale matters

The exhale is roughly twice the inhale, and that ratio is the active part of the technique. A longer out-breath than in-breath is the simplest lever you have on the body's own settling response. It is the same reason a sigh feels like relief. The hold in the middle is what makes the ratio easy to keep without rushing.

When to use it

In bed, lights out, lying on your back. It is a sleep-onset pattern rather than an all-day one: the long exhale and the seven-count hold are strong enough that people often feel a little floaty after a few rounds. It also works before something you are dreading, when the goal is to come down rather than sharpen up.

How often

Four rounds is a full dose, and Dr. Andrew Weil, who popularised the pattern, has long suggested keeping it to four rounds at a time when you are starting out. Twice a day is plenty. More rounds is not better here; the technique is meant to be short.
