Summarize the evidence or lack thereof for the efficacy of physical exercise as a strategy to reduce anxiety and depression
What will be an ideal response?
It appears that there is substantial evidence for the efficacy of physical exercise as a strategy to reduce anxiety and depression, even in clinical populations, with the effect being greater for depression than anxiety. Exercise also seems to counteract insomnia and buffers the physiological effects of stress. Further, there is evidence that regular exercise boosts psychological well-being. Optimal mood-enhancing dosage levels of exercise appear to be in the range of the U. S. Department of Health and Human Services' recommendation of a minimum of 150 minutes of moderate intensity aerobic activity spread out over the week. Although there are a number of hypothetical mechanisms explaining these beneficial effects, each has only limited empirical support.
