Guided breathing

The techniques

Box breathing (4-4-4-4: in, hold, out, pause) is used to regain focus and calm. The 4-7-8 (in 4, hold 7, out 8) is often suggested to help with sleep. Coherent breathing (5-5) aims at about 6 breaths per minute, a naturally relaxing pace.

How to use it

Breathe through your nose, relax your shoulders, and follow the circle without forcing: if a rhythm feels uncomfortable, pick a shorter one or customize the timings. 2-5 minutes are enough.

A general wellbeing tool, not a medical treatment: for anxiety or breathing disorders, see a professional.

Why a long exhale calms you

It is not suggestion: it is the vagus nerve. When you inhale the heart speeds up slightly, when you exhale it slows down, an automatic reflex called respiratory sinus arrhythmia. Making the exhale longer than the inhale therefore tips the balance towards the parasympathetic system, the one for rest and digestion, and the body reads that as a signal that the danger has passed.

That is why 4-7-8, with an exhale twice as long as the inhale, is recommended in the evening, while box breathing, which keeps all four counts equal, is better at steadying you than at putting you to sleep.

The rhythm the body prefers

Around six breaths a minute something curious happens: the swing in heart rate driven by breathing falls into phase with the natural swing in blood pressure, and the two add up. In the heart-rate-variability literature this is called resonance, and it corresponds roughly to the 5-5 coherent breathing on this page.

The exact number is personal and depends mostly on body size: some people resonate at 5.5 breaths a minute and some at 6.5. If 5-5 feels awkward, the counts can be changed by hand: the goal is a breath that flows, not a task to complete.

How to breathe, in practice

Through the nose, which warms and humidifies the air and naturally slows the flow. With the belly, letting it rise while the shoulders stay still: if the shoulders lift you are using the upper chest, which is the breathing of anxiety, not of calm. And above all without filling up: slow breathing is also shallower than usual, because the point is not to take in more air but to take in less, more slowly.

Two to five minutes are enough to feel the effect. The holds on full or empty lungs, if they are uncomfortable, can be shortened: no benefit depends on toughing it out.

When to stop, and when this is not the right tool

A little tingling in the hands or lips means you are breathing too much, not too little: that is hyperventilation, and it passes on returning to a normal breath. If you feel dizzy, stop and wait sitting down — never standing, never driving, never in water. Breath holds in particular must never be practised in a pool or at sea.

Anyone with breathing or heart conditions, uncontrolled high blood pressure, epilepsy or a pregnancy should talk to a doctor first, and anyone with panic attacks should know that counting breaths can increase attention on breathing itself, which is sometimes exactly the problem.
