The Link Between Sedentary Activities and Increased Depression Risk

Mentally-passive sedentary activities, such as watching TV, have been linked to a 43% higher risk of developing depression, while mentally-active sedentary behavior, like sitting at work, does not have the same effect, according to a study published in the Journal of Affective Disorders. The research also suggests that waist size and inflammation may partly explain the association between mentally-passive sedentary behavior and depression. The study highlights the importance of reducing mentally-passive sedentary time and increasing physical activity to improve mental health. However, self-reporting and potential changes in sedentary behavior patterns over time are limitations of the study.
