A daily brisk walk: the strongest-evidenced thing on this list, and it's free
Evidence is good enough to be worth trying for this claim. · Multiple large RCTs or meta-analyses agree.
Thirty minutes of brisk movement most days has more evidence for mood than any supplement here, with a sleep benefit thrown in. It is the baseline every other experiment should be compared against. Test it first; test the pills after.
The world's evidence
- Effect, in daily-life terms
- Regular moderate exercise reduces depressive symptoms with an effect size comparable to first-line treatments in meta-analyses, and improves sleep quality modestly; benefits appear within weeks and hold across ages.
- Who was studied
- Umbrella review of 97 reviews (>128,000 participants) in 2023; meta-analyses of RCTs in both clinical and healthy populations.
Worth knowing
Safe for nearly everyone at brisk-walk intensity. Start below what feels easy if you have been inactive; late-evening vigorous exercise can delay sleep for some people.
