Exercise May Prevent DepressionNot Just Alleviate It
Getting a decent amount of exercise may be one way to prevent depression symptoms, according to a new study. Prior research has shown that exercise is a non-invasive way to curb depression, but fewer studies have looked at whether exercising can actually prevent the emergence of depressive symptoms. In a new study published in the journal Medicine  Science in Sports  Exercise, researchers showed that physical activity may give women an extra edge in warding off depression that can sometimes come with aging and worsening health. The researchers looked 10 years' worth of data from 2,891 women between ages 42 and 52, who filled out questionnaires about their depressive symptoms and levels of physical activity. They found that the women who were meeting public health recommendations for physical activity150 minutes a week of moderate intensity exercisereported fewer depressive symptoms. The more physical activity the women said they did, the less likely they were to have signs of depression. "Given the high prevalence of depression in the United States, particularly for women, exercise is still not considered a first-line treatment option, even though exercise can be of low cost and low risk, can be sustained indefinitely, and has additional benefits for multiple aspects of physical health and physical function," the authors write in the study. "Our findings suggest that motivating midlife women to maintain at least some level of moderate-intensity physical activity may be protective against depressive symptoms, with some activity better than inactivity."
