What is mindfulness?
Mindfulness comes from sati, a concept in Buddhist practice. Jon Kabat-Zinn introduced it to Western medicine in 1979 when he created the eight-week Mindfulness-Based Stress Reduction (MBSR) program at the University of Massachusetts Medical School. He defined mindfulness as "paying attention in a particular way: on purpose, in the present moment, and nonjudgmentally."
Key programs
- MBSR: eight weekly 2–3 hour classes, one full-day retreat and 30–45 minutes of daily home practice (body scan, sitting meditation, yoga).
- MBCT: combines MBSR with elements of cognitive therapy and was developed to prevent depression relapse.
- Short practices: breath awareness, walking meditation and other forms you can fit into daily life.
Does mindfulness actually work?
A 2014 meta-analysis in JAMA Internal Medicine (47 trials with active controls, 3,515 participants) found mindfulness meditation produced small-to-moderate reductions in anxiety (effect size 0.38), depression (0.30) and pain (0.33), with moderate-strength evidence. But there was no evidence it beat medication, exercise or other behavioral therapies. In the 2023 TAME randomized controlled trial of 276 adults with anxiety disorders, eight weeks of MBSR was noninferior to the anti-anxiety drug escitalopram (Lexapro).
Limits and cautions
Meditation studies are hard to blind because participants know what they're doing, and program content and intensity vary from study to study. Rarely, people report worsening anxiety, panic, dissociation or traumatic memories during meditation, so anyone with severe psychiatric symptoms should practice with a professional's guidance. For how stress affects body and mind, see stress theory.

FAQ
- How long do I need to meditate to see benefits?
- Studies typically use about 8 weeks of regular practice, often 20–45 minutes a day, but even shorter daily sessions can help some people; consistency matters more than length.
