Low-intensity exercise can reduce depression, suggests new study

PTC News Desk: A recent study found a significant connection between reduced depression risks and low-to-moderate-intensity exercise. An extensive review of studies conducted globally by researchers at Anglia Ruskin University (ARU) examined the potential of physical activity as a mental health intervention.

Physical activity lowers risk of depression by 23%

The study, published in the journal Neuroscience and Biobehavioural Reviews, discovered that physical activity decreased the risk of depression by 23% and anxiety by 26%. A particularly strong link was discovered between low and moderate physical activity, which included activities like gardening, golf, and walking, and a lower risk of depression. However, this was not as noticeable for high-intensity exercise.

Physical activity was also found to be significantly associated with a lower risk of severe mental health conditions, including a 27% reduction in psychosis/schizophrenia.

The findings were consistent in men and women, across age groups, and around the world.

According to lead author Lee Smith, Professor of Public Health at Anglia Ruskin University (ARU), "Preventing mental health complications effectively has emerged as a major challenge and an area of paramount importance in the realm of public health. These conditions can be complex and necessitate a multi-pronged approach to treatment, which may encompass pharmacological interventions, psychotherapy, and lifestyle changes."

"These effects of physical activity intensity on depression highlight the need for precise exercise guidelines. Moderate exercise can improve mental health through biochemical reactions, whereas high-intensity exercise may worsen stress-related responses in some individuals."

"Acknowledging differences in people's response to exercise is vital for effective mental health strategies, suggesting any activity recommendations should be tailored for the individual."

"The fact that even low to moderate levels of physical activity can be beneficial for mental health is particularly important, given that these levels of activity may be more achievable for people who can make smaller lifestyle changes without feeling they need to commit to a high-intensity exercise programme."
