Its well known that laughter has the power to heal. Researchers are finally conducting studies to scientifically prove this point-- which is right in line with recent evidence that a positive outlook can save your life. It is a certain lightness of heart that keeps it healthy. In a recent study at the University of Maryland, blood flow was monitored in 20 healthy young adults while watching both tragic and comedic film clips. The subjects were asked to abstain from any blood flow altering activities such as drinking alcohol, exercising or ingesting herbs or vitamins 24 hours before the study. Viewing comedic material boosted blood flow in 19 of the subjects, akin to undertaking heart treatment drugs or aerobic exercise, revealed researchers. During a viewing of dramatic war scenes, 14 of the subjects experienced a decline in blood flow, comparable to experiencing stressful, emotionally taxing memories.
