About Deep Breathing

This guide paces your inhale, hold, and exhale so you can follow a rhythm rather than counting. A few minutes is usually enough to notice a difference.

The mechanism is not mysterious. Slow breathing with a longer exhale than inhale stimulates the vagus nerve, which shifts the nervous system toward its rest-and-digest state and slows the heart rate.

How to use it

  1. 1Sit upright somewhere you will not be interrupted for a few minutes.
  2. 2Follow the visual guide, breathing in and out at the pace it sets.
  3. 3Breathe through your nose, into your belly rather than your chest.
  4. 4Continue for at least a few cycles; the effect builds rather than arriving immediately.

Patterns worth knowing

  • Box breathing: in for four, hold for four, out for four, hold for four. Used widely in high-pressure professions because it is easy to remember under stress.
  • The 4-7-8 pattern: in for four, hold for seven, out for eight. The long exhale makes it particularly useful for winding down before sleep.
  • Coherent breathing: around six breaths per minute, roughly five seconds in and five out, which is the rate at which heart rate variability tends to peak.
  • Extended exhale: any pattern where breathing out takes longer than breathing in. This is the active ingredient in most calming techniques.

A note on scope

These are general wellbeing exercises, not medical advice. If you have a health condition, are recovering from injury, or find that an exercise causes pain rather than mild discomfort, speak to a qualified professional rather than working through it.

Frequently asked questions

Why does slow breathing calm you down?

A slow breath with a long exhale stimulates the vagus nerve, shifting the autonomic nervous system toward its parasympathetic state. Heart rate slows and the physical signs of stress reduce measurably.

What is box breathing?

Breathing in for four counts, holding for four, out for four, and holding for four. Its symmetry makes it easy to remember under pressure, which is why it is widely taught in high-stress professions.

How long should I do a breathing exercise?

Two to five minutes is enough to notice a change. Longer sessions are fine, but consistency matters more than duration.

Should I breathe through my nose or mouth?

Through the nose where possible. Nasal breathing filters and warms the air and naturally slows the breath, which is part of the effect you are aiming for.
