Exercise as a First-Line Approach for Depression, Anxiety, and Stress: What a Major Review Found

The relationship between physical activity and mental health has been studied for decades, but individual trials and reviews can be difficult to interpret in isolation. In 2023, researchers led by Ben Singh published an umbrella review in the British Journal of Sports Medicine that brought this evidence together, synthesising findings from a large number of systematic reviews covering randomised controlled trials in adult populations.

The results were consistent and encouraging. Physical activity interventions were associated with medium-sized reductions in symptoms of depression, anxiety, and psychological distress when compared with usual care. Importantly, these benefits were not confined to one group: improvements were seen in healthy adults, people with diagnosed mental health conditions, pregnant and postpartum women, and people living with a range of chronic diseases.

The review also offered practical insights for program design. All major types of activity, including aerobic exercise such as walking, resistance training, Pilates, and yoga, were beneficial. Programs lasting twelve weeks or less were among the most effective at reducing symptoms, which suggests that patients do not need to commit to indefinite regimens before expecting to feel a difference. Higher-intensity activity tended to be associated with greater improvement, though benefits were present across intensity levels.

As with all umbrella reviews, the findings reflect averages across many studies, and individual responses vary. Exercise is not presented as a replacement for professional mental health care where that is needed. Nonetheless, the breadth and consistency of this evidence supports structured physical activity as a core, low-risk component of care for mood and stress-related symptoms, ideally prescribed and progressed with professional guidance.

Key findings

• This overview synthesised evidence from a large body of systematic reviews of randomised controlled trials examining physical activity and mental health outcomes in adults.
• Physical activity was associated with medium-sized improvements in symptoms of depression, anxiety, and psychological distress compared with usual care.
• Benefits were observed across diverse groups, including people with diagnosed depression, pregnant and postpartum women, healthy adults, and people living with chronic conditions.
• All major modes of activity showed benefit, including aerobic exercise such as walking, resistance training, Pilates, and yoga.
• Interventions of twelve weeks or shorter were among the most effective, suggesting benefits can emerge within a realistic program timeframe.

Clinical relevance

Kinesiologists and exercise professionals in rehabilitation settings routinely see patients whose pain and recovery are intertwined with mood and stress; this review supports integrating structured, achievable exercise programming as an evidence-based contributor to mental wellbeing alongside physical recovery goals.
