Exercise and mental health — what the evidence actually supports
A careful read of the depression and anxiety evidence base for physical activity, beyond the 'just go for a run' platitude.
Harvard T.H. Chan School of Public Health7 min read
The evidence that physical activity meaningfully reduces depression and anxiety symptoms is now robust — comparable to first-line treatments for mild-to-moderate depression in some meta-analyses. Harvard Chan's plain-language coverage of the 2023 BJSM umbrella review is a clear summary.
Honest caveats: dose matters, drop-out rates in exercise trials are high, and exercise is not a substitute for treatment in moderate-to-severe illness. It is, however, additive.
