Pattern
4-7-8 breathing
4-7-8 breathing: in for four, hold for seven, out for eight. The long exhale is where the calm comes from.
The pattern
4-7-8
When to use it
- Last thing at night, in bed, lights low.
- After a long flight or a hard day.
- When sleep is close but the mind will not let you in.
- One to three minutes is enough; many people do four cycles and stop.
How to do it
- 01Sit or lie down. Rest the tip of the tongue behind the upper teeth.
- 02Exhale fully through the mouth.
- 03Close your mouth and inhale through the nose for a count of four.
- 04Hold the breath for a count of seven.
- 05Exhale through the mouth for a count of eight.
- 06Repeat for four cycles to start. Build up over time.
What it does
The mechanics are simple: the exhale is twice the length of the inhale. A longer exhale shifts the balance of the autonomic nervous system toward parasympathetic activity, which slows heart rate and lowers arousal.
There is good evidence in the wider HRV literature that slow paced breathing with extended exhales improves measures of vagal tone. 4-7-8 itself has been studied in only a few small trials, mostly with self-report outcomes. The pattern is well-grounded, the strength of the specific claims is not.
It can feel intense at first. The seven-count hold is the part most people resist. If you feel light-headed, shorten the hold and build up.
