Calm Breathing 4-6: 6 Breaths Per Minute Timer

What is 4-6 breathing?

Calm breathing 4-6 means breathing in for 4 seconds and out for 6, with no holds. That works out to six breaths per minute, the pace often called resonance or coherent breathing. Slow breathing near this rate tends to increase heart rate variability, and the longer exhale helps many people feel settled within a minute or two.

Each breath takes ten seconds, so you get exactly six in a minute. There are no holds to manage, which makes it the gentlest pattern on this site and the easiest to keep going for several minutes. It is the default Calm pattern in DeRot for exactly that reason: it works for almost anyone, almost anywhere.

The exhale is a little longer than the inhale. That small tilt toward breathing out is what turns ordinary slow breathing into something that feels like a long, quiet sigh.

How to do it, step by step

Get comfortable. Sit or lie down. Unclench your jaw and let your hands rest.
Breathe in for 4. Breathe in softly through your nose as the circle grows. Let your belly rise rather than your shoulders.
Breathe out for 6. Breathe out slowly through your nose or gently pursed lips as the circle shrinks. Do not push the air out, just let it go.
Keep it smooth. Move straight from the out breath to the next in breath without pausing. Aim for an easy, quiet rhythm.
Continue for a few minutes. Two to five minutes is a good session. When you finish, notice your shoulders and your breathing before you get up.

Breaths should feel easy and a little smaller than you might expect. If you notice yourself gulping air, make each breath lighter.

When to use it

Any time you feel wound up: after a stressful email, a heated thread, or a long scroll.
As a daily practice: a few minutes each morning or evening.
When holds feel uncomfortable: if box breathing or 4-7-8 leaves you short of breath, this pattern has none.
Out and about: it is quiet and subtle enough to do on a bus or in a waiting room.

What the research says

The interest in six breaths a minute comes largely from research on heart rate variability (HRV) biofeedback. Your heart rate naturally rises a little as you breathe in and falls as you breathe out. Researchers Paul Lehrer and Richard Gevirtz describe how, when people breathe at about 0.1 Hz, which is six breaths a minute, these swings become as large as they get. They call this the resonance frequency and note that it varies from person to person, averaging around 5.5 breaths a minute in later work. The leading explanation involves the baroreflex, the system that steadies your blood pressure (Lehrer and Gevirtz, 2014).

A 2018 systematic review of slow breathing in healthy adults found that breathing under 10 breaths a minute was linked with higher HRV and with people feeling more relaxed, comfortable and alert, and less anxious, while cautioning that the number of good quality studies is still small (Zaccaro et al., 2018). A separate review in Breathe walks through how slow breathing affects the heart, lungs and autonomic nervous system, and concludes that it is promising but needs more research (Russo et al., 2017).

You do not need a heart rate monitor to benefit. Six breaths a minute is a sensible, widely used starting point, and it is what this timer gives you.

Who should go gently

This is one of the gentlest breathing patterns there is, with no breath holds. Still, if you feel lightheaded, tingly or uncomfortable, your breaths are probably too big: make them smaller, or stop and breathe normally.

If you are pregnant, have a heart or lung condition, or have a history of panic attacks, keep it easy and stop if anything feels off. This is a general wellbeing tool, not medical advice or treatment. If you have a health condition or concerns, check with your doctor before starting a new breathing practice.

Frequently asked questions

What is resonance breathing?

Resonance breathing means breathing at the slow pace, usually around six breaths a minute, where the natural rise and fall of your heart rate with each breath is at its largest. It is also called coherent breathing or resonance frequency breathing.

Is six breaths a minute right for everyone?

It is a good starting point, but each person's exact resonance rate differs a little, typically somewhere around five to seven breaths a minute. If 4-6 feels rushed or slow, the custom timer lets you adjust it.

Why is the exhale longer than the inhale?

Your heart rate naturally slows slightly as you breathe out, and many people find a longer exhale feels more settling. A 4 second inhale with a 6 second exhale keeps that tilt while staying at six breaths a minute.

Is 4-6 breathing the same as 5-5 breathing?

Both are six breaths a minute. 5-5 uses equal halves, while 4-6 gives the exhale a little more time. Both are commonly called coherent breathing. Pick whichever feels easier.

How long should I practice?

Start with two to five minutes. Many people like a few minutes once or twice a day. A single minute is still worthwhile, and it is what DeRot uses for a quick reset.

Want this to show up mid-scroll?

DeRot pauses your scroll and walks you through a breath like this one. Sixty seconds later your shoulders have dropped, your head feels clearer, and you carry on, calmer. No willpower needed, just a breather.
