Use the timer first, read this after

Press Begin. The circle grows for four seconds, holds for seven and shrinks for eight, so you follow a shape instead of counting numbers in your head. Everything below is for after your first round.

This page is the tool. If you want the background — where the pattern came from, what it asks of the body, how to build it into something regular — the full 4-7-8 guide covers that properly. Come back here when you just want to run a session without reading anything.

The default here is five minutes, which is a little under sixteen full rounds. Your first three sessions run with nothing to sign in to; after that the timer is part of one plan, three days free and then $10 a month or $100 a year. Your settings and your session history stay in your own browser rather than on a server, and once this page has loaded the timer keeps running without a connection. What the site itself collects, and when, is set out in the privacy policy.

How to do it

1. Pick your session length

Open the settings with the gear icon on the timer. Five minutes is the default and a reasonable first session. Three minutes is enough if the seven-count hold is new to you. If you are using this in bed, set ten minutes or choose Unlimited and let it run until you stop noticing it.

2. Sit or lie down where you can stay still

Feet flat on the floor, or on your back with a pillow under your knees. Let your jaw and your shoulders drop before you press Begin. Give yourself somewhere you will not need to get up from for a few minutes.

3. Empty your lungs before the first inhale

One easy breath out through the mouth, all the way, before the circle starts moving. Starting the pattern on a full chest is what makes the seven-count hold feel like a struggle, and most people who say 4-7-8 does not suit them are starting on a full chest.

4. Breathe in with the circle, not ahead of it

The circle grows for four seconds. Take the whole four, through your nose, gently. Most people fill up in two and then sit there waiting for the animation to catch up, and that waiting is what makes the pattern feel tight.

5. Keep the hold loose

Through the seven-count your throat stays open and your face stays soft. You are pausing, not bracing. If you notice yourself clamping down, that is a signal to shorten the pattern rather than push through it.

6. Spend the whole eight seconds emptying

Out through the mouth, lips slightly parted, thin and slow, until the circle is at its smallest. Thin and slow beats hard and fast. This long exhale is the part of the pattern most people came for.

7. Stop on an exhale

When the session ends, or when you press Stop, let the last breath out completely and breathe normally for a few seconds before you get up. Standing straight out of a slow-breathing session is how people end up light-headed and blame the pattern.

Getting the pacing right

One full round is nineteen seconds, which is far slower than most people breathe at rest. It is normal for the first two or three rounds to feel like a lot of air management and not much air. By the fourth or fifth round the counts usually stop feeling like an instruction and start feeling like a rhythm — that is the point where the session becomes worth doing.

The ratio matters more than the exact seconds. If the seven-count has you gasping into the exhale, the pattern is too big for you today, not permanently. Halve everything — two in, three and a half held, four out — and the shape is unchanged. Count that version on your own for a week or two, then come back to this timer.

The gear icon opens three controls: sound, vibration and session length. Sound plays a soft tone at every phase change. Vibration pulses on a phone. With both on you can close your eyes and never look at the screen, which is the whole point at bedtime. Turn sound off and leave vibration on if someone is asleep next to you.

Under the circle, the first bar tracks the session and the second tracks the phase you are in. If watching them turns you back into someone counting, look away. The audio cue is enough on its own, and the timer keeps its own count of breaths for you.

Common mistakes

  • Racing the circle. Counting faster in your head than the animation moves, then holding still until it catches up. Let the shape set the speed.
  • Taking a huge inhale. Four seconds of gentle nasal breathing, not four seconds of filling up. A big inhale makes the hold much harder and the exhale rushed.
  • Bracing through the hold. Closed throat, tight jaw, shoulders up by the ears. If that is what is happening, the hold is too long for you right now.
  • Blowing the exhale out. Eight seconds of thin, quiet air beats three seconds of force followed by five seconds of nothing.
  • Doing twenty rounds on day one. Three or four rounds is a real session. Longer is not automatically better, and long first sessions are how people end up light-headed and put the whole thing down.
  • Saving it for emergencies. A pattern you have practiced calmly is much easier to reach for when you are not calm. Run it on ordinary evenings too.
  • Standing up straight afterwards. Sit for a few normal breaths first.

Where it fits in a sleep routine

Two placements work for most people, and they are doing different jobs.

The first is a wind-down, ten to twenty minutes before you want to be asleep, sitting up, lights low, phone already on its charger. Here the pattern works as a marker: it tells the rest of your evening that the working part of the day is finished. Five minutes is plenty.

The second is in bed, on your back or your side, after you have woken at three in the morning and started thinking. Set ten minutes or Unlimited, sound off, vibration on, screen face down. The aim is not to fall asleep during the session — chasing sleep tends to keep people awake. The aim is to have something to do that is not thinking.

What this pattern will not do is override the things that actually keep people up: a late coffee, a bright screen at midnight, a bedroom that is too warm, a mind full of a real problem, or a sleep disorder. If you are regularly awake for hours, breathing is a poor substitute for saying so to a doctor. There is a fuller evening routine, with the other patterns that suit different parts of a night, on breathing exercises for sleep.

If the hold is the thing keeping you from using this at night, cyclic sighing gives you a long exhale with no hold at all and is easier to do lying down. You can try every pattern side by side on the all timers page.

When to use it, and when not to

Good moments: the half hour before bed, the gap between finishing work and eating, the ten minutes after a difficult conversation, the wait before something you are dreading. It suits any situation where you have somewhere to sit and a few uninterrupted minutes.

Poor moments: anything that needs your attention. Driving, cycling, cooking over a hot stove, being in or near water. Also mid-panic, if breath-holds are part of what panic feels like for you — a hold can read as the start of one rather than the end of it.

Before you use the seven-count hold

4-7-8 holds the breath for seven seconds every round, so this section is not boilerplate.

  • Talk to a clinician first if you are pregnant, or if you live with a cardiovascular condition, uncontrolled high blood pressure, epilepsy, a respiratory condition such as asthma or COPD, or glaucoma, or if you have had surgery recently.
  • If you live with panic attacks or panic disorder, holding the breath can feel like the beginning of one. Cyclic sighing and extended exhale give you the long out-breath without any hold.
  • Practice sitting or lying down. Never while driving, cycling, swimming or in a bath.
  • Stop if you feel dizzy, light-headed, tingly or short of breath, and breathe normally until it passes. That feeling is a reason to shorten the pattern, not to push through it.
  • This is a relaxation exercise. It is not treatment for insomnia, anxiety or anything else.

What the evidence shows

The honest version: 4-7-8 has been measured a handful of times, in small studies, and the results are modest and mostly short-term rather than dramatic.

In a 2022 study in Physiological Reports, 43 healthy adults aged 19 to 25 did three sets of six 4-7-8 cycles, with a minute of normal breathing between sets, while their heart rate and blood pressure were recorded. Everyone did the breathing; the two groups in that sentence are people who normally slept enough and people who did not. The authors report that “Both groups had significantly decreased HR and systolic BP (p < 0.05)” after the exercise (read the study on PubMed Central). Read that carefully: there was no comparison group that skipped the breathing, the readings were taken immediately after the last cycle in the same lab visit rather than weeks later, and only seven of the 43 participants were men, which the authors list as a limitation.

The closest thing to a sleep result comes from a 2026 randomized controlled trial in Brain and Behavior, in which 48 people with chronic tinnitus were split between a one-hour information session alone and the same session plus six weeks of 4-7-8 practice, four cycles each morning and evening. The authors report that “When the experimental group and the control group were compared after the intervention, a significant decrease was found in all questionnaire and VAS scores of the experimental group” (read the trial on PubMed Central), and the questionnaires included the Insomnia Severity Index. That is 23 people practicing, in one specific patient group — a reason to think the pattern is worth six weeks of your evenings, not proof that it will do anything for you.

What none of this shows is that a breathing timer treats insomnia, anxiety or any medical condition. 4-7-8 is short, free and low risk for most people, and that is the entire claim this page makes.

Common questions

How many rounds fit into a five-minute session?

One full round is nineteen seconds, so five minutes is a little under sixteen rounds and three minutes is about nine. You do not need to count them. The timer stops on its own.

What if the seven-second hold is too long?

Shorten the whole pattern rather than just the hold, so the shape stays the same: two seconds in, three and a half held, four out. Count that version on your own for a week or two, then come back to the timer when seven feels unremarkable.

Do I need the sound on for the timer to work?

No. Sound and vibration are both optional and both live behind the gear icon. With sound off and vibration on you can run a whole session with your eyes closed and the phone face down.

Should I do this in bed or before bed?

Either works, and they do different jobs. Sitting up before bed makes the pattern a wind-down cue. Lying down in bed gives you something to do other than think. Do not judge a session by whether you fell asleep during it.

Is this page the same as your 4-7-8 guide?

No. This page is the timer, with notes on pacing, common mistakes and where the pattern fits in an evening. The 4-7-8 guide is the long explainer: where the pattern comes from, what it asks of the body, and how to build a regular practice.
