A new analysis of dozens of clinical trials suggests a surprisingly effective – and accessible – tool in the fight against depression: exercise. Researchers found physical activity can provide relief from depressive symptoms comparable to that achieved through customary treatments like psychotherapy and antidepressant medication.The complete review, conducted by Cochrane and published this week, involved nearly 5,000 adults and reinforces growing recognition of the connection between physical and mental well-being, particularly as depression affects over 300 million people globally according to the World Health Association.
Depression affects millions worldwide, and a growing body of research suggests that physical activity can be a powerful tool in managing its symptoms. A comprehensive analysis of numerous clinical trials indicates that exercise may be as effective as traditional treatments like psychotherapy or medication in alleviating depressive symptoms.
The new analysis, conducted by Cochrane – a highly respected international organization dedicated to evaluating scientific evidence – found that exercise can be comparable to established treatments for depression, according to researchers. This finding offers a potentially accessible and safe option for individuals seeking relief from the condition.
The analysis encompassed 73 clinical trials involving nearly 5,000 adults diagnosed with depression, evaluating the strength of evidence supporting the impact of physical activity on depressive symptoms. Researchers assessed common symptoms like low energy, persistent sadness, sleep disturbances, and feelings of hopelessness.
The results revealed no significant differences between exercise and standard treatments – including psychotherapy and medication – in reducing these symptoms. This suggests that exercise can be a viable alternative or complement to conventional care.
Researchers emphasize that exercise appears to be a safe and accessible option for managing depression, highlighting the importance of identifying strategies that patients are willing and able to maintain long-term.
However, the researchers also caution that the number of high-quality clinical trials remains limited. Most of the included studies involved fewer than 100 participants, which restricts the ability to draw definitive conclusions, particularly regarding long-term effects.
This analysis comes as depression is recognized as a leading cause of illness and disability globally, affecting over 300 million people, according to the World Health Organization (WHO).
The analysis did not identify one type of exercise as definitively superior to others. Participants who engaged in light to moderate-intensity exercise reported greater benefits compared to those following more intense programs.
Improvements in depressive symptoms were associated with a total of 13 to 36 exercise sessions. Combining aerobic exercise with resistance training appeared more effective than aerobic exercise alone.
The analysis did not include activities such as yoga, qigong, or stretching exercises, with the authors noting that these should be investigated separately in future studies.
Prescribing exercise for depression is already a common practice in many healthcare systems. Several international guidelines recommend physical activity as a therapeutic option, particularly for mild to moderate depression.
The European Psychiatric Association recommends physical activity to alleviate symptoms and improve physical condition, emphasizing moderate to vigorous intensity.
In the United Kingdom, the National Institute for Health and Care Excellence (NICE) recommends group exercise programs, with at least one session per week for a minimum of 10 weeks, led by trained personnel.
The Canadian Network for Mood and Anxiety Treatments recommends exercise as a standalone treatment for mild to moderate depression and as a complementary intervention alongside therapy and medication for more severe forms.
The analysis was conducted by researchers at the University of Lancashire, with support from the National Institute for Health and Care Research (NIHR) Applied Research Collaboration North-West Coast (ARC NWC).
