Mindfulness for sleep has modest, real support, but it is not a cure for insomnia. In trials, mindfulness programmes improved self-reported sleep quality more than attention-matched activities did, yet they have not been shown to beat proven sleep treatments, and the effect on objectively measured sleep is weaker. For chronic insomnia, the recognised first-line treatment is cognitive behavioural therapy for insomnia (CBT-I). Mindfulness is best treated as a way of meeting a wakeful night, not a switch for sleep.

Below: the studies and what each was compared against, how mindfulness stands next to CBT-I, a few attributed practices for the day and for bedtime, what the early Buddhist texts say about sleep, and when to see a doctor. For the practice itself, start with what mindfulness is.

What the research shows, and which study is which

The older, broader review. In 2014 Goyal and colleagues pooled 47 randomized trials (3,515 participants) of meditation programmes in many adult clinical groups, counting only trials with active comparison programmes. For sleep they found “low evidence of no effect or insufficient evidence of any effect”. That is the finding our benefits of mindfulness page reports, and it stands. But sleep was mostly a side outcome there, measured in trials of other problems such as fibromyalgia or dementia caregiving.

The later, sleep-specific studies recruited people whose main problem was poor sleep, so they ask a different question. They do not overturn Goyal; they add to it.

In Black’s trial, a six-week Mindful Awareness Practices course lowered Pittsburgh Sleep Quality Index scores from 10.2 to 7.4, against 10.2 to 9.1 with sleep hygiene education. Outcomes were self-reported and measured only at the end of the course; the authors offered mindfulness as “a short-term solution” and said longer-term effects still needed research. Ong’s trial, whose lead author developed MBTI, compared the programmes with self-monitoring, so it shows they did better than watching your own sleep, not that they match treatment.

Rusch’s meta-analysis is the most useful single summary. Against attention-matched activities, mindfulness improved sleep quality (effect size 0.33 after treatment, 0.54 at follow-up). Against established sleep treatments, which the review calls evidence-based (relaxation, exercise, a sleeping drug, sleep education with exercise, and CBT-I in two of the seven trials), it made no difference, a finding graded low-strength, with results that varied widely from trial to trial. The authors call their results “preliminary”: mindfulness “may be effective in treating some aspects of sleep disturbance.” Perini’s authors likewise say MBTI’s benefit over an active programme was “limited to only a few outcomes, with insomnia severity being the most notable.”

One pattern runs through all of this: self-reported sleep improves more than measured sleep. Ong and Smith write that effects “appear to be strongest on self-report measures compared to objective measures of sleep”; Perini found no significant difference between groups on objective measures; and only two trials in Rusch’s review measured sleep objectively. Feeling you slept better is worth having, but it is not the same as sleeping longer.

Mindfulness or CBT for insomnia?

If you have chronic insomnia, the guidelines are clear. The American College of Physicians (2016) recommends that all adults “receive cognitive behavioral therapy for insomnia (CBT-I) as the initial treatment for chronic insomnia disorder” (a strong recommendation). The American Academy of Sleep Medicine (2021) also strongly recommends multicomponent CBT-I, and suggests clinicians not use sleep hygiene on its own: worth remembering when a mindfulness trial beats sleep hygiene education. The AASM’s evidence review looked at mindfulness, and its guideline made no recommendation on it either way.

Head-to-head evidence is thin. Rusch’s review lists two trials with CBT-I as the comparison. In the larger, Garland’s 2014 trial of people with cancer and insomnia, MBSR was inferior to CBT-I right after treatment and not inferior three months later. The authors concluded that CBT-I “remains the best choice for the nonpharmacologic treatment of insomnia.” Rusch’s review notes that half of that trial’s MBSR group dropped out, against 14% of the CBT-I group.

MBTI is not mindfulness alone, either. Its developers describe an eight-week programme that “uses some behavioral strategies for insomnia (stimulus control and sleep restriction) with mindfulness principles and meditations.” Those two strategies are core parts of CBT-I, so MBTI’s results cannot be credited to meditation by itself.

Ong and Smith write that mindfulness therapies “could serve as a viable alternative to CBT-I and pharmacotherapy for insomnia”. That is the view of MBTI’s developer, and the guidelines recommend CBT-I first. Perini’s team puts it more narrowly: MBTI “may be an attractive alternative for those who did not respond or do not have access to CBT-I.” The fair summary: CBT-I first. Mindfulness, including MBTI, is an option to discuss with a clinician, especially if CBT-I is unavailable or has not worked: a choice to make with a clinician, not instead of one. In the UK, the NHS says a GP may offer CBT “face-to-face with a therapist, or through an online self-help programme”, and that sleeping pills are now rarely prescribed.

How mindfulness is meant to help: not a sleep switch

The most useful idea from the clinical programmes is easy to miss. Ong and Smith write that “the practice of mindfulness meditation is not intended to promote sleep onset.” You are not meditating in order to fall asleep. In MBTI, meditation is used “to distinguish the state of sleepiness from other states”, which then guides what you do, such as “going to bed only when sleepy”. The NHS self-help list gives the same advice: “only go to bed when you’re sleepy”. Attention becomes information rather than effort.

And if you are lying awake, the American Academy of Sleep Medicine’s patient advice is plain: “If you don’t fall asleep after 20 minutes, get out of bed. Go do a quiet activity without a lot of light exposure.” The skill MBTI trains, noticing sleepiness, is what tells you when to go back.

Why might it help? Black and colleagues write that mindfulness is “believed to function on arousal”, a hypothesis, not a demonstrated mechanism. Either way, the aim when you lie awake is to notice the wakefulness and the thoughts riding on it, not to force sleep. For the 2 a.m. thought loop, see Buddhism and overthinking.

Practices to try, by day and at bedtime

None of these is a treatment. In the programmes studied, the core practice is a daily session, not a bedtime trick. Formal meditations in mindfulness-based insomnia programmes “typically last 30 to 45 minutes” and are led in class or by audio at home (Ong and Smith). Home practice in Black’s course “began with 5 minutes daily and then progressively advanced to 20 minutes daily”. Neither describes practising in bed to fall asleep. Each practice below comes from a named source; try one for a week or two, and drop it if it does not suit you.

A body scan, before bed or in it

Mindfulness-based insomnia programmes include “quiet meditations such as breathing awareness or the body scan meditation” among their formal practices. Doing a shorter scan in bed as a wind-down is an adaptation the trials did not test. The method is in our body scan guide, which also gives a short version. Drifting off partway is fine at bedtime; sleepiness during meditation practice is a different matter.

A few minutes of kindness

The six-week course in Black’s trial included “friendly or loving-kindness meditation.” In the Pali canon, AN 11.15 lists “You sleep at ease. You wake happily. You don’t have bad dreams” as the first benefits of loving-kindness (mettā), though only when it has been “cultivated, developed, and practiced, made a vehicle and a basis, kept up, consolidated, and properly implemented” (trans. Bhikkhu Sujato), not after one night. The full list of eleven benefits is in Buddha quotes on love. The method is in our guide to loving-kindness meditation.

Resting on the breath, or counting it

Breath counting has a traditional source rather than a clinical one. Buddhaghosa’s Visuddhimagga, a fifth-century Theravāda commentary, tells a seated beginner to count breaths from one up to between five and ten, and calls counting “simply a device for setting mindfulness on the in-breaths and out-breaths”. It is the first stage of a seated concentration practice (ānāpānasati), not a sleep technique, and no sleep trial we read uses it; if you try it in bed, treat it as an anchor, not a sedative. One caveat: for some people, when anxiety is sharp, attention on the breath can intensify panic; the feet, the hands or sounds work as anchors too (see Buddhism and anxiety). Paced techniques such as 4-7-8 are breath control, a different thing: see breathwork.

What about sleep apps?

One randomised trial tested a commercial app directly. Huberty and colleagues (PLOS ONE, 2021) assigned 263 adults with sleep disturbance either to the Calm app, at least 10 minutes a day for eight weeks, or to a waiting list. App users had less daytime fatigue, daytime sleepiness and pre-sleep arousal than the waiting list did. Sleep quality was measured only in the app group, so the trial cannot say whether the app improved it compared with doing nothing. The lead author declares that she serves, as a consultant, as Calm’s Director of Science, and three co-authors sit on Calm’s Scientific Advisory Board. Doing better than a waiting list is not the same as matching treatment.

What the Pali texts say about sleep

The Pali canon of the Theravāda tradition says a good deal about sleep, but none of it is an insomnia treatment, and programmes such as MBTI are secular clinical programmes, not Buddhism (see secular mindfulness). The closest text to “mindfulness for sleep” is a short discourse on falling asleep:

It is addressed to monks and nuns (“mendicants”), it assumes protective deities, and its last item belongs to monastic life. It describes the fruit of a trained mind, not a technique that guarantees sleep.

Another discourse puts good sleep in the mind, not in comfort. In AN 3.35, Hatthaka of Āḷavī finds the Buddha sitting on a thin mat of leaves by a cow-path in mid-winter and asks if he slept well. “I am one of those who sleep at ease in the world,” the Buddha replies, and then asks about a rich man in a warm, draught-free house:

The same is said of hate and delusion, and the discourse closes with a verse: “the peaceful sleep at ease, / having found peace of mind.” Dhammapada 201 says something close: “The peaceful sleep at ease, / having left victory and defeat behind” (trans. Bhikkhu Sujato; see Buddha quotes on happiness).

Sleep as a training in wakefulness

For monastics, though, sleep was something to keep short, not something to improve. In AN 3.16 a mendicant “dedicated to wakefulness” meditates walking and sitting by day and through the first watch of the night; in the middle watch they “lie down in the lion’s posture—on the right side, placing one foot on top of the other—mindful and aware, and focused on the time of getting up”; in the last watch they rise and meditate again (trans. Bhikkhu Sujato).

That is roughly a third of the night for sleep: a discipline for renunciants, the opposite of a sleep aid, and not something to copy if you have insomnia. What carries over is narrower: lying down “mindful and aware” is an old practice (see meditating lying down).

When meditation can disturb sleep

Meditation is not risk-free, and sleep is one of the things it can disturb.

• In clinical programmes, harms look uncommon but are under-measured. Rusch’s review found “no evidence of increased risk of harm” in the 10 of 18 trials that reported adverse events at all. The authors add that symptoms can worsen in the early weeks, and that a history of trauma, mental-health difficulties, addiction or major life changes may call for closer clinical support.
• Insomnia as a side effect is uncommon, but it matters. In a study of Mindfulness-Based Cognitive Therapy (MBCT) courses (96 adults with mild to severe depression), Britton and colleagues found insomnia was reported by fewer than 5% of participants, but it was among the reactions linked to lasting bad effects.
• Measured sleep can move either way. Ong and Smith review two small studies of MBCT in people with depression and insomnia. In those not taking antidepressants, the MBCT group reported better sleep, but not significantly more than a waiting-list group did, and their laboratory recordings showed more awakenings, more light sleep and less deep (slow-wave) sleep than the controls; the researchers could only speculate why. In those taking antidepressants, MBCT brought less time awake and better sleep efficiency than the control group, on the recordings and in sleep diaries.
• Intensive practice is different. In interviews with 60 Western Buddhist meditators chosen because they had had difficult experiences, sleep changes were often reported: less need for sleep, insomnia, nightmares or vivid dreams. Most of the difficult experiences in that study arose on retreat. The authors stress that their numbers do not show how common this is and do not apply to mindfulness courses.

The practical rule: keep bedtime practice short and gentle. If it reliably leaves you more wired, move it earlier, try another anchor or stop, and talk to a clinician or experienced teacher.

When to see a doctor

The NHS advises seeing a GP if changing your sleeping habits has not helped, if “you’ve had trouble sleeping for months”, or if insomnia is affecting daily life “in a way that makes it hard for you to cope.”

See a doctor, too, if your breathing stops and starts in your sleep, if you make gasping, snorting or choking noises, or if you always feel very tired in the day. These are signs of sleep apnoea, which the NHS warns “can be serious if it’s not diagnosed and treated.” Mindfulness does not treat it.

Sleep and mood are tangled together: the NHS names stress, anxiety and depression among the most common causes of insomnia. If worry or low mood keeps you awake, it deserves care in its own right: see mindfulness for anxiety and mindfulness for stress, and Buddhism and depression. If you are in crisis, please contact a doctor or emergency service now.
