What is mindfulness and does it actually work?

Answered by Dr. Nitnem Singh Sodhi · Mental Health Counsellor, Neuropsychologist & Psychotherapist · Updated 2026-06-30

Short answer

Mindfulness has strong evidence for anxiety, recurrent depression and chronic pain when practised as a structured 8-week program (MBSR/MBCT). It has weaker evidence when done as a 5-minute app habit.

Mindfulness is the practice of noticing what is happening in the present moment — thoughts, sensations, sounds — without immediately reacting to it. Stripped of the wellness marketing, it is a specific attention-training skill with a real neurological signature.

Where the evidence is strong

Mindfulness-Based Cognitive Therapy (MBCT) roughly halves the relapse rate in people with three or more previous depressive episodes — comparable to maintenance antidepressants. MBSR reduces GAD symptoms and chronic pain distress. Both are 8-week structured programs with a trained instructor.

Where it is weaker or actively unhelpful

For acute severe depression, active PTSD, or psychosis, unsupervised meditation retreats can worsen symptoms — this is well documented. For everyday use, 5 minutes on an app is fine but do not expect it to treat clinical illness. And 'mindfulness' has been diluted by hustle culture into 'mindful productivity' which is the opposite of the point.
