Meditating on your own for felt stress
Checked against 1 peer-reviewed source, most recently on 22 October 2026.
If you feel stressed most days, you do not need a course, a teacher or a subscription to try the practice the trials tested. In randomised trials, adults who practised mindfulness on their own from books, recordings or apps reported less stress than people who did not. The practice they were asked to do was usually daily and about a quarter of an hour on average. The free fix: sit and notice your breath or body every day for a month.
The one honest fix
Once a day, sit quietly for about fifteen minutes, noticing your breath or body without changing anything, and gently come back when your mind wanders. Keep going for a month.
What the evidence says
In a meta-analysis of randomised controlled trials of unguided mindfulness self-help - practising mindfulness alone with books, recordings, websites or apps, with no teacher or therapist - the trials in adults who had not been recruited for any mental or physical health problem found that people who practised reported less stress afterwards than comparison groups (Hedges' g -0.36, 95% CI -0.49 to -0.24 - a small effect; 37 trials). Most comparison groups were waiting lists or carried on as usual
g -0.36 vs control · 95% CI -0.49 to -0.24
Limitations & how to read this number
Stress was measured with questionnaires the participants filled in themselves, most often the Perceived Stress Scale, and in almost every trial the participants knew whether they had been given the mindfulness materials: only 6 of the review's 83 trials described adequate blinding of participants and staff. The people in these trials were students, employees, health workers, carers and similar groups who had not been recruited because of a health problem, so this says nothing about treating anxiety, depression or any illness. Across the review the participants were on average about three quarters women and three quarters White, with an average age of about 35. Practice was guided by recordings, websites, apps or books - some of them commercial apps - rather than done in silence with no instructions. The suggested daily practice ranged from 3 to 45 minutes, about 15 minutes on average, usually every day, for between ten days and three months. On average about a third of the people given the materials dropped out of the trial before the end. The results varied considerably from trial to trial, and the difference was smaller when the comparison group was given another activity to do instead of nothing (see below). Two of the review's three authors have received research funding from Headspace, a company that sells a mindfulness app, and the first author's PhD studentship was part-funded by it; the review states that the company had no part in the study or the paper.

How to actually do it
Pick a time you already keep every day, sit somewhere quiet, and set a timer for about fifteen minutes. Rest your attention on your breathing or on the feeling of your body, without trying to change it. When your mind wanders - it will - notice that, and come back. Do it every day for at least a month. If you want a voice to follow, any free guided body scan or breathing-awareness recording will do; in the trials, books and CDs showed a similar reduction in stress to apps and websites. The suggested daily practice in the trials ranged from 3 to 45 minutes, about 15 on average, for ten days to three months.
Supporting findings (3)
Across all 47 trials in the same meta-analysis that measured stress - including those in people recruited because of mental or physical health problems - people who practised mindfulness from self-help materials reported less stress at the end than comparison groups (Hedges' g -0.41, 95% CI -0.52 to -0.29; 47 trials)
g -0.41 vs control · 95% CI -0.52 to -0.29
This combines every trial in the review that measured stress, including ten in people recruited because of mental or physical health problems, so it is a broader group than the main result above. The trials' results varied considerably. When the trials whose results lay furthest from the average were set aside, the estimate barely changed. The same limits apply as to the main result: questionnaires filled in by participants who knew which group they were in, and many people stopping early.

In the same meta-analysis, the difference in stress was smaller in the 17 trials whose comparison group was given another activity - such as relaxing music, relaxation exercises, expressive writing or other apps - than in the 30 trials whose comparison group got nothing or carried on as usual, but it was still there (against another activity, g -0.22, 95% CI -0.38 to -0.07; against nothing, g -0.52, -0.67 to -0.36)
g -0.22 vs another activity · 95% CI -0.38 to -0.07
Most of these comparison activities were general ones meant to occupy people for a similar amount of time, not other proven ways of handling stress. In the few trials that compared mindfulness self-help with an established approach, the review found no clear difference on any mental health or wellbeing outcome. So this shows that the practice did better than simply being given something to do, not that it beats other good options.

In the 14 trials in the same meta-analysis that measured stress again between one and twelve months after the practice period ended, the difference was smaller but still present (Hedges' g -0.22, 95% CI -0.33 to -0.10; 14 trials)
g -0.22 at follow-up · 95% CI -0.33 to -0.10
Only a minority of trials checked again later, the follow-up times ranged from one month to a year, and the review could not tell whether people were still practising by then. The review did not report this follow-up result separately for adults recruited without a health problem, so it may include trials in people recruited for health problems.

What the trials tested
The review pooled 83 randomised trials of mindfulness self-help - books, CDs, websites, downloadable recordings and apps - with no teacher and no personal support from a therapist or researcher. Most of the trials were in students, employees, health workers and similar groups who had not been recruited because of a health problem. Stress was measured with questionnaires before and after, and compared with people who were put on a waiting list, carried on as usual, or were given a different activity.
How big the difference is
It is a small effect: on average, people who practised ended up reporting somewhat less stress than people who did not. The gap was smaller when the comparison group was given another activity, such as relaxing music or a writing task, instead of nothing - but it was still there. In the trials that checked again one to twelve months later, the gap had narrowed but had not gone. It is an average across groups, not a promise for any one person.
Does this lower cortisol?
This review cannot say. Every result in it comes from questionnaires about how stressed people felt; it did not pool cortisol or any other measurement taken from the body. What it shows is that people who practised said they felt less stressed - which is the part you actually notice.
How this is different from slow breathing
Slow breathing, our fix for coming down out of stress, changes your breathing on purpose, to a set slow pace. Mindfulness does not ask you to breathe any particular way: the breath is just something to rest your attention on while you practise noticing and coming back. They are different practices, tested in separate reviews.
Who paid for the research
Two of the review's three authors have received research funding from Headspace, which sells a mindfulness app, and the first author's PhD was part-funded by it. The review says the company had no part in the study or the paper. Several of the trials tested commercial apps, but the trials using books and recordings showed a similar reduction in stress - nothing on this page needs you to buy anything.
Questions people ask
Is a few minutes of meditation a day enough?
The trials do not answer that for stress. The practice they suggested was usually daily and about fifteen minutes on average, ranging from three to forty-five, and the review did not test whether longer practice lowered stress more. Fifteen minutes a day is what the trials asked people to do, on average.
Can mindfulness make me feel worse?
Paying close attention to what you feel can bring up unpleasant thoughts or feelings as well as pleasant ones, and the review's authors say it is not without risk; only a few of the trials reported checking for harms. These trials were in people not recruited for a health problem. If you are struggling with anxiety, low mood or stress that does not let up, this is not a substitute for talking to a doctor.
