A new, comprehensive analysis confirms that physical activity is a highly effective treatment for depression and anxiety, offering benefits comparable to therapy or medication. The research suggests that specific types of exercise, such as group activities for depression or short-term programs for anxiety, can be tailored to maximize mental health benefits for different people. These findings were recently published in the British Journal of Sports Medicine.
Mental health disorders are a growing concern across the globe. Depression and anxiety affect a vast number of people, disrupting daily life and physical health. While antidepressants and psychotherapy are standard treatments, they are not always sufficient for every patient. Rates of these conditions continue to rise despite the availability of traditional cares.
Health experts have explored exercise as an alternative or add-on treatment for many years. However, previous attempts to summarize the evidence have faced challenges. Earlier reviews often mixed data from healthy individuals with data from patients suffering from chronic physical illnesses. This made it difficult to determine if mental improvements were due to exercise itself or simply a result of better physical health.
To address this uncertainty, a team of researchers conducted a “meta-meta-analysis,” also known as an umbrella review. This is a highly rigorous study design that sits at the top of the evidence hierarchy. Instead of running a new experiment on people, the researchers analyzed data from existing meta-analyses.
A meta-analysis pools the results of many individual scientific experiments to find a common truth. This umbrella review went a step further by pooling the results of those pools. The goal was to provide the most precise estimate possible of how exercise impacts mental health.
The research team was led by Neil Richard Munro from James Cook University in Queensland, Australia. He collaborated with colleagues from institutions in Australia and the United States. Their primary aim was to isolate the effect of exercise on mental health by excluding studies involving participants with pre-existing chronic physiological conditions.
This exclusion was a key part of their methodology. By removing data related to conditions like heart disease or cancer, the team removed potential confounding factors. They wanted to ensure that any observed benefits were due to the direct impact of exercise on the brain and psychological state.
The researchers searched five major electronic databases for relevant literature. They gathered data from studies published up to July 2025. The scope of their search was massive, covering children, adults, and older adults.
The final dataset included 63 umbrella reviews. These reviews encompassed 81 specific meta-analyses. In total, the analysis represented data from 1,079 individual studies and involved 79,551 participants.
The sheer volume of data allowed the researchers to look for subtle patterns. They examined different types of exercise, such as aerobic activities, resistance training, and mind-body practices like yoga. They also analyzed variables like intensity, duration, and whether the exercise was performed alone or in a group.
The overarching finding was clear and positive. Exercise reduced symptoms of both depression and anxiety across all population groups. The magnitude of the benefit was described as medium for depression and small-to-medium for anxiety.
For depression, the study found that all types of exercise were beneficial. However, aerobic exercise—activities that get the heart rate up, like running or cycling—showed the strongest impact. This suggests that cardiovascular engagement may trigger biological pathways that fight depressive symptoms.
The social context of the physical activity also appeared to matter greatly for depression. The data indicated that exercising in a group setting was more effective than exercising alone. Similarly, programs that were supervised by a professional yielded better results than unsupervised routines.
These findings regarding group and supervised settings point to the importance of social support. The shared experience of a class or team environment may provide a psychological sense of belonging. This social connection likely acts as an additional antidepressant mechanism alongside the physical exertion.
The study identified specific demographic groups that responded particularly well to exercise. “Emerging adults,” defined as individuals aged 18 to 30, saw the greatest benefits for depression. This is a critical age range, as it often coincides with the onset of many mental health challenges.
Another group that saw substantial benefits was women in the postnatal period. Postpartum depression is a severe and common condition. The finding that exercise is a highly effective intervention for this group offers a promising, non-pharmaceutical tool for maternal mental health.
When analyzing anxiety, the researchers found slightly different patterns. While aerobic exercise was still the most effective mode, all forms of movement helped reduce symptoms. This included resistance training and mind-body exercises like yoga or tai chi.
The optimal parameters for anxiety relief were notably different than for depression. The data suggested that shorter programs were highly effective. Interventions lasting up to eight weeks showed the strongest impact on anxiety symptoms.
Regarding intensity, the findings for anxiety were somewhat counterintuitive. Lower intensity exercise appeared to be more effective than high-intensity workouts. This could be because high-intensity exertion mimics some physical symptoms of anxiety, such as a racing heart, which might be uncomfortable for some patients.
The researchers compared the effects of exercise to traditional treatments. They found that the benefits of physical activity were comparable to those provided by psychotherapy and medications. This positions exercise not just as a lifestyle choice, but as a legitimate clinical intervention.
Despite the strength of these findings, the authors noted several caveats. The definitions of exercise intensity varied across the original studies, making it hard to set precise boundaries. What one study considers “moderate” might be “vigorous” in another.
There was also a potential sign of publication bias in the anxiety studies. This refers to the tendency for scientific journals to publish positive results more often than negative ones. However, the sheer number of studies analyzed provides a buffer against this potential distortion.
Another limitation was the overlap of participants in some of the underlying reviews. The researchers used a statistical method to check for this duplication. While some overlap existed, particularly in studies of youth and perinatal women, the overall quality of the evidence remained high.
The authors emphasized that motivation remains a hurdle. Knowing exercise helps is different from actually doing it. Future research needs to focus on how to help people with depression and anxiety stick to an exercise routine.
The study supports a shift in how mental health is treated clinically. The authors argue that health professionals should prescribe exercise with the same confidence as they prescribe pills. It is a cost-effective, accessible option with few side effects.
For public health policy, the implications are broad. The study suggests that guidelines should explicitly recommend exercise as a first-line treatment. This is especially relevant for young adults and new mothers, who showed the strongest responses.
Tailoring the prescription is key. A “one size fits all” approach does not apply to mental health. A depressed patient might benefit most from a running group, while an anxious patient might prefer a gentle, short-term yoga program.
The authors concluded that the evidence is now undeniable. Exercise is a potent medicine for the mind. The challenge now lies in integration and implementation within healthcare systems.
Mental health professionals can use these findings to offer evidence-based advice. They can move beyond vague recommendations to “be more active.” Instead, they can suggest specific formats, like group classes for depression, based on rigorous data.
Ultimately, this study serves as a comprehensive validation of movement as therapy. It strips away the noise of co-occurring physical diseases to show that exercise heals the brain. It offers a hopeful, empowering path for millions struggling with mental health issues.
