4-7-8 breathing: slow down in 19 seconds a round, with a free timer

How to do 4-7-8 breathing

1. Sit upright with your back supported, or lie down. Many versions put the tip of the tongue against the ridge just behind the upper front teeth and keep it there.
2. Breathe out completely through your mouth with a soft whooshing sound.
3. Close your mouth and breathe in quietly through your nose for a count of 4.
4. Hold your breath for a count of 7.
5. Breathe out slowly through your mouth for a count of 8.
6. That is one round. Repeat for about four rounds, then breathe normally.

Ready when you are

Start

Sit or lie down. If you feel dizzy, lightheaded or uncomfortable, stop and breathe normally. Not suitable as a substitute for medical advice. Nothing you do here is recorded or sent anywhere.

What to change if it feels hard

The sources agree on one practical point: the ratio matters more than the length of each count. If seven counts of holding feels strained, speed the counting up so every phase gets shorter, and keep the 4:7:8 proportions. The "Pace" setting in the timer does this for you. Work up to the standard pace over several days if you like, or stay at a shorter pace if it suits you.

Lightheadedness is common at first. That is why guides suggest sitting or lying down. Stop and breathe normally at the first sign of dizziness, tingling or breathlessness.

What the evidence says

One review notes plenty of anecdotal reports that slow, rhythmic breathing feels relaxing, and limited scientific research on the 4-7-8 pattern itself. The best randomized evidence in this area is for other practices, such as cyclic sighing, where an exhale-focused practice improved mood in a 2023 trial. That does not make 4-7-8 ineffective for you, but it does mean claims of falling asleep within a minute go further than the evidence.

Which pattern should I pick?

If you want	Try
A slow wind-down at night	4-7-8, sitting up or lying down
An even, steady rhythm	Box breathing (4-4-4-4)
Something quick with no counting	The physiological sigh
A gentle start	Longer exhale (in 4, out 6), no holds

Common mistakes

• Starting with too many rounds. Four is plenty at first.
• Breathing too deeply or fast. Keep it quiet and soft.
• Straining on the hold. Shorten the counts instead.
• Doing it standing. Sit or lie down, in case you feel lightheaded.

Who should check first

Breath-holding is the part to be careful with. Run it past a doctor first if you are pregnant, faint easily, or live with heart or lung disease. For a broader look at popular claims, read vagus nerve exercises: what the evidence supports.
