The latest research on treating mental health problems with
exercise
There is growing scientific interest in using exercise to
support our mental health – and two major research papers published in British
Journal of Sports Medicine and The BMJ have provided some of the most
comprehensive evidence yet. Both studies examine how exercise impacts
depression and anxiety, bringing together evidence from hundreds of previous
studies to answer a critical question: How effective is exercise for mental
health?
Here’s what we found.
The big picture: exercise works
The first review was an “umbrella review”, meaning it
analysed results from multiple previous studies. It included data from more
than 79,000 people. The conclusion: exercise consistently reduces symptoms of
depression and anxiety.
For depression in particular, the effects were moderate,
meaning they are large enough to be clinically meaningful, enough that doctors
should be prescribing exercise for the treatment of depression. Anxiety
symptoms also improved, with small-to-moderate effects across a wide range of
populations. Interestingly, the mental health improvements were seen across all
age groups, from younger adults to women in the postnatal period.
Importantly, benefits were higher in:
- People with diagnosed mental
health conditions (for example depression) - Individuals with chronic illness
- Postnatal women
This makes the findings relevant and achievable for a wide
range of people, not just elite athletes or fitness enthusiasts.
What type of exercise helps most?
The second paper took a closer look at which specific
exercise types and doses might be most effective for treating clinical
depression. It pooled evidence from over 200 randomized controlled trials
involving more than 14,000 participants. Three approaches stood out:
- Walking or jogging
- Strength training
- Yoga
Each significantly reduced depressive symptoms, with some
forms performing comparably to traditional treatments like psychotherapy or
medication.
One interesting insight is that intensity matters.
Higher-intensity exercise tended to produce larger improvements in mood. That
does not mean everyone needs to train like an athlete, but it suggests that
gently pushing beyond your comfort zone may bring added benefit.
At the same time, even lower-intensity formats, especially
for anxiety, still showed positive effects. So the message is not no pain, no
gain, it is any movement is likely to help.
Supervision and support make a difference
Another key finding: exercise programmes delivered in group
settings or with supervision often produced stronger results. This may reflect
accountability, structure, social connection – or all three.
That is encouraging news for community classes, walking
groups and supervised gym sessions. Mental health benefits do not just come
from the movement itself, they may also come from shared experience.
Why this matters
These reviews reinforce something powerful: exercise is not
just lifestyle advice, it now forms evidence-based treatment for mental health
problems.
For clinicians, it strengthens the case for prescribing
physical activity alongside conventional therapies. For individuals, it offers
an accessible, low-cost strategy with wide-ranging physical and psychological
benefits. Of course, exercise is not a replacement for all treatment, and
professional care is important.
