What extended exhale breathing is
One pattern, two parts, no holding: you breathe in for a count of four and let the air leave over a count of six. A full cycle takes ten seconds, so you end up at six breaths a minute without having to think about it.
Most of the patterns on this site ask you to hold your breath somewhere. This one does not, which makes it the plainest thing here and, for a lot of people, the easiest to keep going. There is no moment where you are counting down to being allowed to breathe again. The in-breath arrives, the out-breath arrives, and the only instruction is that the second one lasts longer than the first.
The asymmetry is the point. Your heart rate speeds up slightly while you breathe in and slows slightly while you breathe out — a normal, healthy fluctuation that most people never notice. Making the out-breath the longer half means more of every cycle is spent on the slowing side. Whether that produces the calm people describe, or whether the calm comes mostly from sitting still and counting for five minutes, is genuinely hard to separate. Both are probably doing something.
What is fair to say is that slow breathing at around six breaths a minute is one of the better-studied things you can do with your breath, and that a longer out-breath is one of the standard ways of getting there.
How to do it
1. Sit down and let your shoulders drop
Sit upright with both feet on the floor, or lie down if you would rather. Let your jaw and shoulders go loose. You do not need to sit in any particular way for this to work.
2. Breathe in through your nose for four
Take a gentle breath in through your nose while the circle grows, for a slow count of four. This is not a big breath. If your shoulders lift, you are pulling too hard. Aim for the breath to move your belly more than your chest.
3. Let the out-breath run for six
Let the air leave for a count of six while the circle shrinks. Do not push it out. Think of it as unclenching rather than blowing. If you run out of air at four, you took in more than you needed on the way up.
4. Go straight into the next breath
There is no hold in this pattern. As soon as the out-breath ends, the next in-breath begins. One full cycle takes ten seconds, which is six breaths a minute.
5. Keep going for three to five minutes
Set the timer and let it count for you. Stop earlier if you feel light-headed, and breathe normally until that passes. Light-headedness usually means you are taking in more air than you need, not less.
When people reach for it
This is the pattern to try first if holding your breath makes you uneasy. Anyone who finds a four-second hold unpleasant — and that includes a lot of people who have had panic attacks — usually gets on much better with a pattern that never stops moving.
It also travels well. Nobody can tell you are doing it. It works sitting at a desk, in a waiting room, on a bus, or lying in the dark at two in the morning, and it does not need you to close your eyes or hold a posture.
People tend to use it in three places: as a wind-down before sleep, as a reset between two things that both need attention, and as something to do with the twenty minutes before an appointment they are dreading. None of those is a treatment for anything. They are ways of spending a few minutes that are better than scrolling.
If you want something with more structure, box breathing holds the breath at both ends and gives you four equal counts to follow. If you want something slower still, heart coherence runs at five in and five out. If you want the shortest possible version, cyclic sighing takes a double in-breath and one long out-breath.
Making the pattern your own
Four and six is a starting point, not a prescription. Two things are worth adjusting.
The size of the counts. If four seconds in feels like too much air, try three in and five out. If both halves feel short, five and seven or five and eight are common. What matters is that the out-breath stays the longer half and that neither half feels like effort. Straining defeats the whole exercise.
The gap between them. Some people find that a one-second pause after the out-breath, before the next in-breath, makes the pattern feel less relentless. The timer here does not build that in, but the custom pattern builder will let you set one if you want to try it.
Whatever you settle on, keep it for a week before changing it again. Patterns feel different on day one and day five, and swapping every session tells you nothing.
Who should take it slowly
Extended exhale breathing holds nothing and hyperventilates nothing, so it is the mildest pattern on this site. It is still worth reading this before you start.
- If you have a heart or lung condition, are pregnant, or are recovering from surgery, ask the person treating you before taking up any breathing practice.
- If you have asthma or COPD, a long forced out-breath can be uncomfortable. Keep it gentle, and stop if it makes you cough or tighten.
- Light-headedness, tingling in the hands or lips, or a feeling of not getting enough air all mean stop. Breathe normally and let it settle. It is not dangerous, but there is no reason to push through it.
- Never use a breathing timer while driving, cycling, swimming, or in a bath.
- If slow breathing reliably makes your anxiety worse rather than better — which happens to some people — that is useful information, and worth mentioning to a clinician rather than working around.

Common questions
Why make the out-breath longer than the in-breath?
Heart rate rises a little on the in-breath and falls a little on the out-breath. Spending more of each cycle on the falling half is the whole idea of the pattern. It is also easier to do badly: a long out-breath is hard to rush, and rushing is what most people do when they are wound up.
Is four and six the right ratio for me?
It is a good place to start, not a rule. If four feels like too much air, try three in and five out. If six leaves you gasping at the end, shorten the out-breath rather than forcing it. The ratio matters more than the numbers: the out-breath should be the longer half and neither half should feel like work.
How is this different from box breathing or 4-7-8?
Both of those hold the breath. This one does not. That makes it the gentlest of the patterns on this site and usually the easiest one to keep going for ten minutes, and it is often a better first pattern for anyone who finds holding the breath uncomfortable.
How long should a session be?
Three to five minutes is a sensible first session, which is eighteen to thirty breaths. There is nothing wrong with one minute if that is what you have. Longer is not automatically better, and a short session you actually do beats a long one you keep meaning to.
Can I do this lying down, or while walking?
Lying down is fine and is how many people use it at night. Walking is fine too, though the count is harder to keep. Do not use a breathing timer while driving, cycling, swimming or in a bath.
Do I need to breathe out through my mouth?
Either is fine. Through the nose is quieter and slower by default. Through pursed lips gives you more control over the length if six seconds feels hard to stretch to. Pick whichever lets you keep the out-breath long without straining.

That review looked at slow breathing under ten breaths a minute in healthy people, and reported that such techniques “seem to promote a predominance of the parasympathetic autonomic system with respect to the sympathetic one, mediated by the vagal activity”, alongside increases in heart rate variability. Its authors are careful about how far that goes: they describe the evidence linking those physiological changes to how people actually feel as “interesting albeit limited”, and attribute the shortage to how differently the studies were run. Read the claims on this page in that light.
