For most beginners, 10 to 15 minutes on most days of the week is a reasonable, evidence-based place to start. In a 2019 trial, 13 minutes of guided meditation a day improved mood, attention and memory after eight weeks, though not after four[1]. Trials comparing 10 minutes with 20 or 30 found no clear advantage for the longer sittings[2][3], and in a study of 1,053 meditators, adding a day a week did more than adding about 10 minutes a sitting[4]. That same study, though, linked meaningful improvements to far more daily practice than most apps suggest.
This post covers dose: minutes per sitting, sittings per day and total practice over time. Whether you need to meditate every single day, and what to do when you miss one, is the subject of our companion piece, do you need to meditate every day?
How many minutes a day should you meditate?
Ten to fifteen minutes is the range with the most direct trial support for beginners. In the 2019 trial, adults aged 18 to 45 with no meditation experience were randomly assigned to a 13-minute guided meditation or a 13-minute podcast every day for eight weeks. Compared with the podcast group, the meditators had less negative mood, better attention, working memory and recognition memory, and lower anxiety during a laboratory stress test at eight weeks. None of those differences had appeared at four weeks[1]. The trial was small and used one guided program, so treat eight weeks as a rough guide, not a rule.
Longer sittings have not clearly beaten shorter ones in head-to-head tests. In a 2023 study of 372 adults recruited online, a single 10-minute mindfulness meditation raised state mindfulness as much as a 20-minute one, and meditation overall beat listening to a control recording. In an exploratory analysis, 20 minutes lowered anxiety more only among people who were already high in trait mindfulness[2]. Another 2023 trial assigned 161 adults to about 10 or about 30 minutes of daily sitting or movement meditation for two weeks. Well-being rose and distress fell in all four groups, with no differences by dose[3]. That trial had no inactive control group and lasted only two weeks.
Reviews of full mindfulness courses point the same way. A 2020 meta-regression of 203 randomized trials with 15,971 participants found that mindfulness-based programs beat control conditions on depression, anxiety and stress, but larger doses of contact time or practice did not predict larger improvements on most of those outcomes. Dose did predict gains in mindfulness itself[5].
Is it better to meditate longer or more often?
More often, according to the best data available, though none of it comes from a randomized trial. A 2025 study followed 1,053 meditators through nine surveys over two months, with a follow-up two to four years later. The number of days a week people practiced predicted every outcome measured, including distress and life satisfaction, while minutes per day predicted only two of them. The authors estimated that adding a day of practice a week did more than adding about 10 minutes to each sitting[4]. Participants averaged about five days a week and roughly half an hour a day. The doses were self-reported, people chose how much to practice, and the sample was mostly English-speaking and 69% female.
Splitting your daily time also seems fine. In a 2024 trial, 351 undergraduates with elevated depression or anxiety used a meditation app for two weeks, either as one 20-minute meditation a day or two 10-minute ones. Both groups improved, with no difference between them[6]. It was a first test over a short period in students, so it shows flexibility is reasonable, not that the two are equal in every case.
How much meditation does it take to make a lasting difference?
More than the short trials suggest, if the long-term studies are right. In the 2025 study above, after accounting for each person's past practice, the authors estimated that 35 to 65 minutes a day were needed for a meaningful improvement in well-being during the two months, and 50 to 80 minutes for mental health outcomes such as distress[4]. An earlier survey by the same group of 1,668 meditators found that lifetime hours of practice were linked to better well-being, with the link strongest over roughly the first 500 hours before it leveled off. The associations were modest, with correlations of 0.18 to 0.28[7].
Structured courses ask for a similar amount. A meta-analysis of home practice in MBSR and MBCT, the two best-studied mindfulness courses, found that across 43 studies with 1,427 people, participants did 64% of the practice assigned to them, about 30 minutes a day, six days a week. Across 28 of those studies, more practice was linked to better outcomes, though the link was small (r = 0.26)[8]. In all of this research, people who feel better may simply practice more, so these figures show association, not cause.
| Dose tested | Who and how long | What was found |
|---|---|---|
| 10 vs 20 minutes, once | 372 adults online, one sitting | No difference between lengths; meditation beat a control recording[2] |
| About 10 vs 30 minutes a day | 161 adults, 2 weeks | All groups improved; no difference by dose[3] |
| 13 minutes a day | Small trial of new meditators, 8 weeks | Better mood, attention and memory at 8 weeks, not at 4[1] |
| One 20 vs two 10-minute meditations a day | 351 distressed students, 2 weeks | No difference[6] |
| About 30 minutes, 6 days a week | MBSR and MBCT home practice, 43 studies | More practice, slightly better outcomes[8] |
| Self-chosen, about 5 days a week | 1,053 meditators, 2 months | Days per week mattered more than minutes[4] |
How should a beginner choose a meditation dose?
Start with a length you can repeat on most days, hold it for eight weeks, then add time only if you want more.
- Choose 10 to 15 minutes as your normal length, the range tested in the short trials. Set a timer or use a guided recording of that length.
- Get the days right before the minutes. Aim for five or more days a week before you lengthen anything.
- On busy days, split the time into two shorter meditations, or do a two-minute one rather than skipping. There is little research on doses that short, but it keeps the routine going.
- Hold the same dose for about eight weeks, the point at which the 13-minute trial first found benefits.
- If you want more, add five minutes at a time, or add a second short meditation later in the day.
- Each week, write down how many days you meditated, your usual length and one word for how you feel. After two months, compare.
Whitespace is a self-guided meditation app that speaks: you bring the intention, and it writes and voices a meditation for exactly that. Its two-minute meditations are free, which covers the short days in step 3.
Can you meditate too much?
There is no well-established upper limit, but meditation is not free of side effects, and more is not automatically safer. A 2020 systematic review of 83 studies with 6,703 participants found adverse events in 8.3% of people overall, 3.7% in experimental studies and 33.2% in observational ones. Anxiety and depression were the most common, and they sometimes appeared in people with no history of mental health problems[9]. The review did not establish whether longer or more frequent practice raises the risk. If a longer dose leaves you more unsettled, go back to the length that felt manageable, and talk to a doctor or therapist if the effects persist.
Questions people ask
Is 5 minutes of meditation a day enough?
It may help, but most trial evidence for daily practice uses 10 to 15 minutes or more. Five minutes is a sensible starting point if longer feels out of reach, and you can build from there.
Is 20 minutes of meditation better than 10?
Not clearly. A study of 372 adults found 10 and 20 minutes raised mindfulness equally in one sitting, and a two-week trial found no difference between about 10 and about 30 minutes a day.
How long does it take for meditation to work?
In one trial, 13 minutes a day produced measurable changes in mood and attention after eight weeks but not after four. Some studies find small shifts after a single sitting, but steadier change needs weeks of practice.
Can I split my meditation into two shorter ones?
Yes. In a two-week trial of 351 students, two 10-minute meditations a day worked as well as one 20-minute meditation.
How many days a week should I meditate?
Aim for most days. In a study of 1,053 meditators, days per week predicted outcomes more strongly than minutes per day. Our post on whether you need to meditate every day covers missed days in more detail.
