A new study suggests that exercise boosts the mood for longer than originally thought. It appears that moderate intensity aerobic exercise improves mood immediately after and those improvements can last up to 12 hours discovered by researchers at the University of Vermont, Burlington. The mood of the exercisers was better than that of the sedentary group immediately after the workout and for up to 12 hours later. Results show that even moderate aerobic exercise has the potential to mitigate the daily stress that results in an altered mood. This study shows that exercise is a good way to cope with stress of life that does not cost a lot. Experts believe that exercise’s mood-boosting effects are partly due to a rise in levels of mood-enhancing neurotransmitters, such as endorphins, in the brain. The American College of Sports Medicine guidelines support the 2008 Physical Activity Guidelines for Americans, which recommend that adults get at least 150 minutes of moderate-intensity physical activity each week. That can be done in five days a week in 30-minute sessions, experts suggest.
