Islamabad (The COW News Digital) Regular physical activity may help reduce the impact of genetic susceptibility to depression, according to a new US study published in the journal Nature Mental Health. The research suggests that staying physically active could play an important role in managing depression-related symptoms, even among individuals with a higher genetic risk.
Researchers analysed data from 23,517 individuals, examining survey responses, electronic health records, genetic information and physical activity measurements collected through Fitbit devices. By combining these sources, the researchers investigated the relationship between genetic predisposition to depression, physical activity levels and the severity of depressive symptoms.
The findings indicated that the association between genetic risk and depression severity was relatively weaker among people who were more physically active. This suggests that regular movement and exercise may help reduce the influence of certain risk factors associated with depression.
According to the research, physical activity could offer a practical way to support mental well-being. Exercise has been associated with several benefits for brain function and emotional health, while also potentially helping the body regulate inflammation and manage the effects of stress.
The findings highlight the potential importance of lifestyle choices in mental health management. Although genetic factors can influence a person’s susceptibility to depression, researchers are exploring how everyday habits and environmental factors may affect the development and severity of symptoms.
Research author Denver Brown said understanding genetic vulnerability could help individuals make informed lifestyle changes that may support depression prevention and symptom management. The study adds to growing scientific interest in how physical activity may complement other approaches to mental health care.
However, the researchers cautioned against interpreting the findings as evidence that exercise alone can prevent or cure depression. Physical activity should instead be considered a potentially useful supportive strategy rather than a replacement for professional assessment, psychotherapy or prescribed medication when these are needed.
Depression is a complex mental health condition influenced by multiple factors, including genetics, life experiences, social circumstances and physical health. As a result, approaches to prevention and treatment may differ from one person to another.
The study also highlights the value of combining genetic information with real-world health records and activity data to better understand the relationship between lifestyle and mental health. Wearable devices such as Fitbits can provide information about movement patterns, helping researchers examine physical activity beyond self-reported exercise habits.
While further research is needed to clarify the relationship and determine which activity levels may offer the greatest benefits, the findings provide additional evidence supporting physical activity as part of a broader approach to mental well-being.
Experts generally recommend choosing activities that suit an individual’s physical condition and abilities. Walking, cycling and other forms of regular movement may help people build sustainable routines, although anyone experiencing persistent depressive symptoms should seek advice from a qualified healthcare professional.
The research offers a promising perspective on how lifestyle changes may support people with a genetic predisposition to depression, while reinforcing that mental health care should be tailored to individual needs.
