The episode explores meditation-related adverse effects ranging from anxiety, insomnia and dysregulation to psychosis and mania. Personal accounts from Sue and Jane illustrate how app-based breathwork and intensive retreats can lead to prolonged distress and lengthy recovery. Researchers discuss possible risk factors, including trauma, pre-existing mental health difficulties, intensive practice and certain personality patterns, while warning against simplistic generalisations. The episode also examines the large MYRIAD school trial, which found no overall mental-health or wellbeing benefits and slight worsening among some vulnerable students. Meditation may still help with conditions such as anxiety, depression and chronic pain, but its potency makes informed consent, appropriate guidance and access to support essential.
