Physical Intervention Mental Health: Exercise More Effective than Medicines
University of South Australia researchers are calling for exercise to be a mainstay approach for managing depression as a new study shows that physical activity is 1.5 times more effective than counselling or the leading medications.
A review published by scientists at the University of South Australia shows that physical activity is extremely beneficial for improving symptoms of depression, anxiety, and distress. Specifically, the review showed that exercise interventions that were twelve weeks or shorter were most effective at reducing mental health symptoms, highlighting the speed at which physical activity can make a change. The largest benefits were seen among people with depression, pregnant and postpartum women, healthy individuals, and people diagnosed with HIV or kidney disease.
According to the World Health Organization, one in every eight people worldwide (970 million people) live with a mental disorder. Poor mental health costs the world economy approximately 2.5 trillion dollars each year, a cost projected to rise to six trillion dollars by 2030.
Lead Unisa researcher, Dr Ben Singh, says physical activity must be prioritised to better manage the growing cases of mental health conditions. “Physical activity is known to help improve mental health. Yet despite the evidence, it has not been widely adopted as a first-choice treatment,” Dr Singh says. “Our review shows that physical activity interventions can significantly reduce symptoms of depression and anxiety in all clinical populations, with some groups showing even greater signs of improvement. Higher intensity exercise had greater improvements for depression and anxiety, while longer durations had smaller effects when compared to short and mid-duration bursts.” The researchers also found that all types of physical activity and exercise were beneficial, including aerobic exercise such as walking, resistance training, Pilates, and yoga. Importantly, the research shows that it doesn’t take much for exercise to make a positive change to your mental health.
Senior researcher, Unisa’s Prof Carol Maher, says the study is the first to evaluate the effects of all types of physical activity on depression, anxiety, and psychological distress in all adult populations: “Examining these studies as a whole is an effective way to for clinicians to easily understand the body of evidence that supports physical activity in managing mental health disorders. We hope this review will underscore the need for physical activity, including structured exercise interventions, as a mainstay approach for managing depression and anxiety.”
