4-7-8 Breath

In for four. Hold for seven. Out for eight.

The long hold and even longer exhale ask a lot of the system: in a good way. Most people are asleep before they get far.

When your mind won't stop and you're trying to fall asleep.

0 = infinite

In other words

A heavier hand on the same brake: hold long enough to feel the pressure build, then let it go all at once.

Benefits

  • Helps you fall asleep
  • Strongly activates the parasympathetic system
  • Quiets a busy mind

When to be careful

  • Avoid if you have uncontrolled high blood pressure, glaucoma, or a history of fainting. The extended hold raises that risk more than shorter-hold techniques.
  • Check with your doctor first if you're pregnant or have a heart or lung condition.
  • Practise sitting or lying down, never while driving.

The science

The long hold raises CO2 slightly, and the extended exhale that follows triggers a deep vagal response. Practised nightly, it conditions the body to relax quickly.

Origin

Developed by Harvard-trained physician Dr Andrew Weil, adapted from pranayama. He designed it as a 'natural tranquilliser for the nervous system', meant to be practised twice a day.

How to

  1. Rest the tongue against the ridge behind the upper front teeth, and keep it there throughout.
  2. Exhale fully through the mouth around the tongue, with a soft 'whoosh'.
  3. Close the mouth and inhale quietly through the nose for four.
  4. Hold for seven. Exhale through the mouth for eight, with the whoosh. That's one cycle.

Common mistakes

  • Rushing the exhale. The count of eight is the whole engine of the technique.
  • Skipping the tongue position, which helps shape a slow, audible exhale.

Dosage

Four cycles, twice a day for the first month, building up to eight cycles per session after that.

How it compares

Box Breathing

Box uses equal holds for focus; 4-7-8 weights the exhale so heavily it pushes you towards sleep rather than sharpness.

Calming Breath

Same family, exhale-led. Calming Breath is the everyday version; 4-7-8 is the pre-sleep heavyweight, with a long hold added in between.

Physiological Sigh

Both are deep calmers. 4-7-8 is a ritual for bed; the Sigh is a single tool you can use mid-meeting.
