A recent study presented at the 56th annual meeting of the American College of Sports Medicine (ACSM) suggests that the mood enhancing effects of exercise can last longer than an hour, as previously thought. Compared with a control group that did not exercise, the survey group of healthy men and women who exercised reported enhanced moods up to 12 hours post-exercise. volunteers performed exercise at 60% of aerobic capacity, which indicates that moderate-intensity exercise is enough to boost mood. Because these effects appear to fade after 12 hours, the researchers are recommending daily exercise. Current ACSM guidelines recommend at least 150 minutes of moderate-intensity exercise each week, which can be achieved in 30 minute segments five days a week.

Lithium is a naturally occurring element that can be found in tap water and is often used to treat mood disorders, such as bipolar disorder and acute mania. So should lithium be added to our drinking water? Not quite yet. There are no large-scale studies to demonstrate feasibility or safety in using lithium to this extent. However, the idea is one which will garner considerable debate. Like many medications it is yet unknown how lithium works in in the brain to treat mood disorders.
