Meta-analyses of randomised trials find moderate effects of exercise on depressive symptoms in mild to moderate depression, with walking, running, strength training and yoga all showing benefit. The mechanism is not settled; sleep, daylight, routine, social contact and brain chemistry all contribute.

What the evidence supports

Consistency over intensity: most trials used two to four sessions a week.
The best exercise is the one you will keep doing.
Group or outdoor activity adds social contact and daylight.
Exercise supports treatment; for moderate or severe depression it is not a replacement for assessment.

Low motivation is a symptom, not a character flaw. A ten-minute walk is a legitimate first step, and professional support can run alongside it.

If you or someone else cannot stay safe, call 999. Samaritans: 116 123, free, 24 hours.
