4-7-8 breathing

how to do it

1. Sit or lie down comfortably. Back straight, shoulders down. Before the first cycle breathe out calmly through the mouth — empty the lungs.
2. Breathe in through the nose for a count of 4. Calm, not maximal. The belly moves forward, the shoulders stay where they are.
3. Hold for a count of 7. Mouth closed. If seven seconds is hard for now, halve all three numbers (2-3.5-4) — the proportion matters more than the absolute values.
4. Breathe out through the mouth for a count of 8. With a sound like "haaa" — or without it, if there are people around. Lips slightly pursed, the air leaving in an even stream rather than a burst.
5. Repeat 4 times. That’s one round. The author of the technique suggests two rounds a day — in the morning and before bed.

The tip of the tongue is held against the palate just behind the upper teeth — a detail from the yogic tradition the technique came from. It has little effect on the result — though it sometimes adds to the feeling of composure.

what makes it work

There’s nothing mystical here — the mechanism is entirely measurable.

The exhale slows the heart. When the exhale is twice as long as the inhale, the "slow" phase takes up more time and the average heart rate goes down. The mechanism is set out in panic attack.

Slow breathing changes the mode of the nervous system. Breathing at around six cycles a minute (and 4-7-8 gives roughly three) raises heart rate variability — a measure linked to resilience under stress. This is the most solid part of the evidence: slow breathing is well studied and it works.

The hold occupies your head. Holding a pause and keeping count is work that takes your whole attention. There are no free hands left for anxious scenarios. A side effect, but a useful one.

To be honest about the evidence: the 4-7-8 pattern itself has barely been studied in large trials of its own. What has been studied is slow breathing with an extended exhale as a class — and there the effect on pulse and on subjective anxiety has been confirmed many times. That is about the here and now, though — about the few minutes you spend breathing. What weeks of regular practice do, and what is known about blood pressure, is a separate conversation: it lives in resonance breathing, and the picture there is thinner. 4-7-8 is a convenient and memorable form of that class, no more and no less.

where the technique came from

The pattern was popularised by the American doctor Andrew Weil, a specialist in integrative medicine. He adapted it from pranayama — the breathing practices of yoga, where working with the ratio of inhale, hold and exhale has existed for several thousand years. Weil calls it "a natural tranquiliser for the nervous system" — a vivid phrase, but one to take as a metaphor rather than as a medical claim.

when 4-7-8 suits, and when something else is better

It works well:

• before sleep. The long hold and the long exhale slow everything down at once. This is the best use of the technique — if you can’t fall asleep, it’s where to start;
• with background anxiety, when thoughts go in circles but there’s no acute attack;
• in the evening after a hard day, to shed the tension that has built up.

Better to choose something else:

• in acute panic. Holding for seven seconds is hard during an attack, and failing at it feeds the anxiety. There the physiological sigh works faster and more simply;
• when you need to gather yourself rather than relax — before a talk or a difficult conversation. Box breathing fits better there: it calms without removing tone;
• while driving or walking. Any breath holding can produce mild dizziness.

what the first sessions feel like

• Dizziness the first few times is normal. It comes from the unfamiliar hold and passes within a few sessions. If the dizziness is strong, breathe normally and wait a minute.
• If four cycles feels like a lot, start with two. The hold trains quickly, and it’s easy to overdo.
• Count evenly. In your head the count quietly speeds up exactly when it should be slowing down, so an external rhythm is better: a timer or vibration.

who should check the holds with a doctor

With pregnancy, high blood pressure, epilepsy, heart or lung conditions, long breath holds are worth clearing first. Slow breathing itself is safe for almost everyone — it’s the pauses that are the question, and in 4-7-8 the pause is longer than in our other calm rhythms. If you’d rather skip holds altogether, resonance breathing 5-5 has none.
