Deep breathing for sleep means slow, gentle belly breathing in bed: a soft breath in through the nose, then a longer, unhurried breath out, at about five or six breaths a minute. Do it for a few minutes with the lights low, without holds or counting pressure. Follow the no-hold timer below, then put the screen away.

How to do deep breathing in bed

1. Get ready for bed first, then dim the lights. Start the timer, or read these steps once and then put your phone away.
2. Lie on your back with a pillow under your knees, or on your side if that is more comfortable.
3. Rest one hand on your belly. Breathe in gently through your nose for about 4 to 5 seconds and let your belly rise under your hand.
4. Breathe out slowly through your nose or softly parted lips for about 5 to 6 seconds. Let the belly fall without pushing air out.
5. Keep each breath small and comfortable. If you feel short of air, make the breath shorter, not bigger.
6. Continue for 5 to 10 minutes, or less if you like. Then let breathing return to its own rhythm and stay lying down.

The timer above uses an even rhythm of about 5.5 seconds in and 5.5 seconds out, with no holds. That is a little under six breaths a minute. You can follow it loosely or stop it and keep breathing at your own slow pace. On most phones, turning the brightness down helps the screen bother you less.

Make it part of a wind-down routine

Breathing tends to work best as one step in a routine you repeat, not as a test of whether you fall asleep tonight.

• Same time each night: Practice at roughly the same point in your routine, such as after brushing your teeth.
• Try it on easy nights too: A familiar exercise is easier to use on a night when your mind is racing.
• Let go of the clock: Watching the time to see whether breathing "worked" can keep you alert. Turn the clock away if you can.
• If you wake at night: A few slow breaths without the screen may help you settle. Skip the timer to avoid bright light.

If you prefer counting, 4-7-8 breathing is a popular bedtime pattern, but it includes a long breath hold that not everyone finds comfortable. The deep breathing guide explains belly breathing in more detail for daytime practice.

When to use it

Use it when you get into bed, when your body is tired but your thoughts keep going, or after waking during the night. Some people also practice for a few minutes earlier in the evening to separate the day from bedtime.

If paying attention to your breath makes you more alert or anxious, try something with an outward or wordier focus. Yoga nidra guides attention around the body, and NSDR-style rest offers short written prompts. The meditation for sleep guide compares bedtime practices, and the breathing exercises guide compares other patterns.

Who should be careful

Stop and breathe normally if you feel dizzy, lightheaded, tingly, short of breath, or more anxious. Slower is not better if it feels like a struggle. Keep breaths gentle rather than large.

If you are pregnant, or have asthma, COPD, a heart or lung condition, or a history of fainting, keep sessions short and gentle and ask a qualified clinician which breathing exercises suit you. Lying flat may be uncomfortable later in pregnancy or with some breathing conditions; lie on your side or prop yourself up instead. New or severe shortness of breath, chest pain, or breathing difficulty needs prompt medical attention.

Breathing exercises are not a treatment for sleep disorders. If you often take a long time to fall asleep, wake up and cannot get back to sleep, snore loudly, stop breathing during sleep, or feel very sleepy during the day, talk with a doctor. Cognitive behavioral therapy for insomnia (CBT-I) is the most strongly recommended treatment for chronic insomnia.

What the research says

Slow breathing before bed has been studied in a small number of trials, and the results are encouraging but limited.

• Systematic review: A 2026 review in Sleep Medicine Reviews found nine studies (457 participants) of slow breathing at 10 breaths a minute or fewer before bedtime. Self-reported sleep duration and quality improved, but sleep measured with devices or sleep studies showed inconclusive results. The authors called for more high-quality, longer studies.
• Insomnia study: A 2015 study compared 14 people with self-reported insomnia with 14 good sleepers. When the insomnia group practiced slow paced breathing for 20 minutes before sleep, they fell asleep faster and woke less in a sleep lab. The sample was very small.
• Healthy adults: A 2019 trial randomized 64 healthy young adults to 15 minutes of slow-paced breathing each evening or social media use for 30 days. The breathing group reported better sleep quality. These were not people with insomnia.

These studies used slow-breathing protocols practiced over days or weeks. They do not show that our timer, or one session, will help you fall asleep. Our research page explains how we weigh studies like these.
