Research details
The review included 17 randomised controlled trials with 1,641 generally healthy adults.
Participants in structured mindfulness-based programmes reported lower perceived stress than comparison groups after the intervention.
The overall difference was moderate and statistically significant, meaning it was unlikely to be due to chance alone in these studies.
The findings concern reported stress, not every physical measure of the body’s stress response.
The results apply specifically to mindfulness-based programmes and should not automatically be extended to every type of meditation.
Teaser
A review of 17 randomised trials found that adults taking part in structured mindfulness programmes reported less stress afterwards than people in comparison groups.

Effects of mindfulness-based interventions on perceived stress among non-clinical adults: a systematic review and meta-analysis
Plain Summary
A recent systematic review and meta-analysis examined whether structured mindfulness-based programmes can help generally healthy adults feel less stressed. These programmes teach meditation along with related mindfulness skills, so the findings apply specifically to this type of programme—not automatically to every form of meditation.
The researchers combined results from 17 randomised controlled trials involving 1,641 adults who were not being treated for a clinical condition. In these studies, participants were assigned either to a mindfulness-based intervention or to a comparison group. After the programme, those who took part in the mindfulness interventions reported lower levels of perceived stress than those in the comparison groups.
The difference was statistically significant. In everyday terms, this means the pattern was unlikely to be explained simply by chance within the studies. The overall size of the difference was moderate: the groups differed by about half a standard deviation, a statistical way of describing a noticeable but not enormous gap in reported stress.
Because the review brought together randomised trials, it provides stronger evidence than a study that only compares people who already choose to meditate with those who do not. Even so, the research measured perceived stress—the way people experienced and reported their stress—rather than showing that the programmes changed every aspect of the body’s stress response. The review’s authors specifically said more research is needed on physiological stress outcomes.
The findings also describe what happened after the interventions studied. They do not establish how long any reduction in perceived stress lasts, or whether the same result would occur with all meditation methods, all programme formats, or all groups of people. The review supports mindfulness-based interventions as potentially useful and scalable options for reducing perceived stress among generally healthy adults, while leaving important questions for future research.
Practical Takeaway
Taken together, this research suggests that structured mindfulness-based programmes may help generally healthy adults experience less stress. The evidence is strengthened by the use of randomised trials and by combining results from 17 studies. However, the outcome was perceived stress, based on participants’ reports, and the review did not establish effects on all physiological stress measures or how long benefits might last. The findings therefore offer encouraging, specific support for mindfulness-based programmes—not a guarantee, and not proof that every meditation approach will have the same effect.
Why this matters
The value of a research finding depends on what was studied, how the study was designed and how consistently its results have been reproduced. This section is intended to connect the findings with meditation practice without overstating what the research can prove.
