To reduce colorectal cancer risk, being active in both the early morning and evening might provide greater benefits than overall activity, a new study indicates.

More is better, but adding even an hour of physical activity a week could reduce risk of developing a common heart arrythmia. And you don’t have to run marathons and climb flights of stairs to get the benefits.

Scientists found that engaging in physical activity between 2.5 and 5 hours per week - the minimum amount recommended by the American Heart Association - showed a 60% lower risk of developing atrial fibrillation.

New research indicates that 1 hour of moderate exercise per week can help prevent atrial fibrillation (AFib). While a small amount of exercise reduced AFib risk, study participants who exercised more reaped even greater benefits.
