Start Here the foundations
Foundational empower-first mood lever. Gordon 2018 meta (JAMA Psychiatry, PMID 29800984): resistance training meaningfully reduced depressive symptoms, roughly 1 in 4 responding, largely independent of how much strength was gained. Small-to-moderate on anxiety too. Belongs at the top with aerobic exercise.

Reducing isolation and loneliness is foundational. Holt-Lunstad 2010/2015 (PMID 20668659, 25910392): strong social ties ~50% higher survival odds; isolation/loneliness/living-alone each 26-32% higher mortality. Association, not proven cause (the isolated differ in health, income, mobility) so name the confounders. Best intervention target is loneliness-driving thoughts (~0.6 SD), not just adding contact; talking therapy g~0.43; video calls alone did little.

Mindfulness gives small-to-moderate drops in anxiety (~0.38 SD) and depression (~0.30 SD) at 8 weeks, roughly level with CBT and medication and well above a waiting list. MBCT cuts depression relapse ~31% vs usual care. Self-directed and free; app-based works for stress. Little effect on positive mood/sleep/weight.

Read Not recommended
Drug ◆ Moderate
Last-resort, clinician-administered. A single IV infusion raised remission odds ~sevenfold at 24h and rapidly cut suicidal ideation, but the effect fades within a week without maintenance.

Education-level hub. Psilocybin, MDMA-assisted therapy, ayahuasca and esketamine show real early signals for treatment-resistant depression, PTSD and end-of-life distress, but they are administered in clinical/legal trial settings with therapy, carry meaningful risk, and psilocybin did not clearly beat a standard antidepressant; microdosing matched placebo. Present as education, never as a self-directed empower-first lever. Individual medicine pages (psilocybin, mdma, ayahuasca, ibogaine) inherit this framing.
