How to use the breathing exercise
- Sit or lie comfortably. Feet on the floor, shoulders down. Once you have the rhythm you can close your eyes.
- Pick a pattern. Box breathing for focus, 4-7-8 to wind down, resonance breathing as a daily practice, the physiological sigh for quick relief.
- Choose a length and press Start. Three minutes is plenty to notice a difference. The timer finishes the round you are in before it stops.
- Follow the circle. Breathe in as it grows, hold while it waits, breathe out as it shrinks. The words and seconds keep the count, so you do not have to.
- Breathe low. Let your belly and lower ribs move rather than your shoulders, and breathe in through the nose.
Which breathing pattern should you choose?
| Pattern | Rhythm | Best for | Try |
|---|---|---|---|
| Box breathing | 4 in · 4 hold · 4 out · 4 hold | Calm focus under pressure | 2–5 min |
| 4-7-8 breathing | 4 in · 7 hold · 8 out | Winding down, falling asleep | 4 rounds |
| Resonance breathing | 5.5 in · 5.5 out | A daily practice for steady calm | 5–10 min |
| Physiological sigh | 2 in · 1 more in · 6 out | Fast relief from acute stress | 1–5 min |
Box breathing (4-4-4-4)
Four equal phases of four seconds: in, hold, out, hold. It is the most widely taught breathing technique and the easiest to remember, which is why it works in a meeting room or just before a difficult conversation. The full guide covers how to do box breathing and the three mistakes people make.
4-7-8 breathing
In for four, hold for seven, out for eight. The long exhale is what slows you down, which makes 4-7-8 the pattern for the end of the day. Start with four rounds and build up from there. More in 4-7-8 breathing: the one for winding down.
Resonance breathing
Five and a half seconds in, five and a half out, no holds — about five and a half breaths a minute. At this pace the natural rise and fall of your heart rate with each breath becomes larger and more regular, which is why resonance breathing is the pattern most often used for a daily practice. Ten minutes makes a good session.
The physiological sigh
A full breath in through the nose, a short extra sip on top, then a long, slow breath out through the mouth. Your body already does a version of this on its own every few minutes. On purpose, one to three rounds is the quickest way to take the edge off acute stress, and in a 2023 Stanford study five minutes a day of this “cyclic sighing” lifted mood more than the same time spent on mindfulness meditation.
What slow breathing does
Slow breathing with a long exhale activates the parasympathetic nervous system — the “rest and digest” branch — largely via the vagus nerve. Heart rate and blood pressure come down, and with regular practice stress, anxiety and sleep tend to improve. The full explanation, including what happens to oxygen, carbon dioxide and cortisol, is in breathwork: what it is, what it does, and how to start.
Safety
Slow breathing is safe for almost everyone. If you feel dizzy or uncomfortable, stop and breathe normally — it is not an endurance test. Breathing exercises are a tool for the moment, not a treatment: if anxiety, panic or sleepless nights have become the rule rather than the exception, talk to a doctor.
Frequently asked questions
How long should a breathing exercise take?
Two to five minutes is enough to feel a difference. For a daily practice, five to ten minutes of resonance breathing is a good target. Consistency matters more than length.
Is box breathing good for anxiety?
It can help calm the body in a stressful moment: the slow, even rhythm and the counting give your attention something steady to hold on to. It is not a treatment for an anxiety disorder, but many people use it alongside one.
Which breathing exercise helps you fall asleep?
Patterns with an exhale that is longer than the inhale, such as 4-7-8. Do four rounds in bed with the lights off, then let your breathing return to normal.
How often should I do breathing exercises?
Once a day as a habit, plus whenever you need it. Attaching it to something you already do — the first coffee, switching off the light — is what makes it stick.
Should I breathe through my nose or my mouth?
Breathe in through the nose. Breathe out through the nose for box and resonance breathing if that is comfortable, and through the mouth for 4-7-8 and the physiological sigh.
