Guided 4-7-8 breathing
4-7-8 Breathing Timer
4-7-8 breathing pairs a short inhale with a long hold and an even longer exhale. Press start and follow the circle. The numbers describe a ratio, so if the standard pace feels like too much, the quicker pace keeps the same shape in half the time.
Ready when you are
One breath takes 19 seconds. If any part feels like a strain, choose a shorter pace or stop. A comfortable breath matters more than the count.

The short answer
4-7-8 breathing is a slow breathing pattern: breathe in through your nose for 4 counts, hold for 7, then breathe out through your mouth for 8. It was popularized by physician Andrew Weil, who adapted it from yogic breathing. A few small studies suggest it can lower heart rate and short-term anxiety, but it has less research behind it than box breathing or slow paced breathing, and claims that it puts you to sleep in a minute are not supported by published trials.
How to do 4-7-8 breathing
- Sit with your back supported. If it feels comfortable, rest the tip of your tongue on the ridge just behind your upper front teeth.
- Breathe out fully through your mouth.
- Close your mouth and breathe in quietly through your nose for a count of four.
- Hold your breath for a count of seven.
- Breathe out through your mouth for a count of eight, slowly and steadily.
- That is one breath. Start with four breaths, and slow down, speed up the count or stop if you feel light-headed.
Where does 4-7-8 breathing come from?
The technique was popularized by Andrew Weil, an integrative medicine physician who adapted it from pranayama, the breathing practices of yoga. His instructions emphasize the 4:7:8 ratio rather than exact seconds, and suggest doing no more than four breaths at a time for the first month before building up to eight.
What does the research say about 4-7-8 breathing?
Direct evidence is limited and comes from small studies. In a 2022 study of 43 healthy young adults, three short sets of 4-7-8 breathing were followed by lower heart rate and systolic blood pressure, and heart rate variability shifted in a favourable direction in participants who were not sleep-deprived. The study did not measure anxiety and did not compare 4-7-8 breathing with another technique.
A 2023 randomized trial of 90 patients recovering from bariatric surgery found lower anxiety scores in the 4-7-8 group than in a deep-breathing group or a routine-care group.
Those results are encouraging but narrow. There are few trials in everyday anxiety, and no good evidence that 4-7-8 works better than other slow breathing patterns. Popular claims that it helps you fall asleep in 60 seconds are not backed by published trials.
Why you can change the pace
At the standard pace, each breath takes 19 seconds and includes a seven-second hold. That is a lot to ask when you are already anxious. The quicker setting keeps the same 4:7:8 shape at half the speed, so a full breath takes under ten seconds.
If the hold still feels uncomfortable, try a pattern without holds, such as coherent breathing or the physiological sigh.
Using 4-7-8 breathing at night
Many people use 4-7-8 breathing as part of a bedtime wind-down. Slowing your breathing can help the body feel calmer, which some people find makes it easier to settle, but it is best treated as a gentle routine rather than a sleep treatment.
If racing thoughts are what keep you awake, our guide to overthinking at night covers other practical ways to step out of the loop.
When 4-7-8 breathing may suit you
- You like a slow pattern with a long exhale.
- You want a short, structured way to wind down.
- A longer breath hold feels comfortable for you.
- You prefer counting a few breaths over watching a clock.
Breathe comfortably
- A slow breath is not the same as a big breath. If you feel light-headed, tingly or short of breath, take smaller breaths, choose a shorter pace or stop.
- Do not practise breath-hold patterns while driving, swimming or anywhere you need to stay fully alert.
- If you have a heart or lung condition, are pregnant or have been told to avoid holding your breath, check with a healthcare professional first and favour patterns without holds.
- If focusing on your breath makes anxiety stronger, try an outward-focused grounding exercise instead. Breathing is one option, not a requirement.
When your body has settled, what about the thought?
In the Reframer app for iPhone and Apple Watch, breathing is one step in a gentle routine. A quick check-in suggests whether to breathe first or try 60-second haptic tapping, haptics keep time on your wrist so you can close your eyes, and when you feel steadier you can work through the anxious thought itself.
Try a different breathing exercise
Box Breathing
In 4 · Hold 4 · Out 4 · Pause 4
Four equal phases for people who like a clear, predictable count.
Physiological Sigh
In · A little more in · Long breath out
A double inhale and a long, slow exhale, with no breath holds.
Coherent Breathing
In 5 · Out 5
About six slow breaths a minute with no holds — the simplest steady rhythm.

Frequently asked questions
Is 4-7-8 breathing counted in seconds?
Not necessarily. Andrew Weil's instructions say the ratio matters more than the exact time spent in each phase. Count at whatever speed lets you finish the exhale comfortably. The quicker setting on this page halves the standard timing.
How many rounds of 4-7-8 breathing should I do?
Weil suggests no more than four breaths at a time for the first month, then up to eight if you wish. This timer offers four or eight breaths.
Does 4-7-8 breathing help you fall asleep?
Some people find it a calming part of a bedtime routine, but it has not been shown in rigorous trials to make people fall asleep faster. Think of it as a way to slow down, not a guaranteed sleep aid.
Why do I feel light-headed during 4-7-8 breathing?
Taking very big breaths or blowing out hard can leave some people light-headed. Breathe in gently rather than deeply, choose the quicker pace or do fewer breaths, and stop if you feel dizzy.
Is 4-7-8 breathing better than box breathing?
There is no good evidence that it is. Box breathing and slow paced breathing currently have more research behind them. The most useful pattern is the one you can do comfortably.
