The effects of exercise on mental health are finally getting some much-needed attention in the scientific community.
For a long time, a growing body of research has connected regular exercise and keeping active in general, with a host of health benefits. Among the most significant associations are reduced risk of all-cause mortality, cardiovascular disease, diabetes, stroke and cancer.
Meanwhile, the relationship between physical activity, brain health and psychological wellbeing has remained largely unexplored. That is, until recently.
A New Study
According to a new cross-sectional study, it is becoming clear there are considerable benefits to mental wellbeing. Not only that, but these benefits can be derived across a broad variety of exercise types.
Lancet Psychiatry recently took on the challenge, exploring the association between exercise and mental health burden. A large sample was used factoring in exercise type, frequency, duration, and intensity.
They found that individuals who exercised in the past month self-reported fewer days (43.2%) of poor mental health than those that did not exercise but were otherwise matched for several physical and sociodemographic variables.
Keeping Active and Activity Types
These findings suggest that regardless of the type of activity you choose, there can still be a significant shift towards improvement. What's more important than the activity type, is simply that you continue to stay active.
Activity Frequency and Duration
Looking at frequency and duration across the entire sample and still consistent across all exercise categories, frequencies of 3-5 times per week and 45 minutes in duration demonstrated the most favourable outcomes. Interestingly, individuals who exercised either less than 3 times or greater than 5 times experienced greater mental health burden.
As a function of duration, exercising less than 30 minutes each session was linked to higher mental health burden. Durations longer than 60 minutes generally fared no better than 45-minute sessions.
- All exercise types were associated with lower mental health burden.
- Among the top-performing types were aerobic or gym training, cycling, running or jogging, walking, and playing popular team sports.
- More is not necessarily better. 45-minute durations and 3-5 sessions per week were associated with mental health improvements.
