5 Health Benefits of Laughing and smiling

Researchers have discovered that blood flow is significantly affected by laughter. 20 healthy subjects were shown a stress-inducing movie, and then a funny laughter-inducing movie. The results? The stressful movie slowed blood flow by 35% and the comedy increased blood flow by almost 22%. Laughter improves the function of blood vessels and increases blood flow and lowers high blood pressure, which in turn helps protect your heart against heart attack and other heart problems.

Boosts your mood

Laughing and smiling are natural anti-depressants. They increase the level of happy, health-enhancing hormones like endorphins and neurotransmitters in your brain, and reduces the level of stress hormones like cortisol, epinephrine, adrenaline, and dopamine. Higher levels of endorphins can give you an instant mood boost making you a happy, positive person. If you want to boost your mood, studies show that the positive effects of laughing and smiling happen regardless of whether or not your smile is real.
