Laughing makes you smart and keeps you healthy
Already in earlier studies, scientists came to the results that laughing and smiling reduces stress and reduce our sense of pain.
And it gets even better: Researchers have also found that laughter reduces the production of stress hormones and increases levels of natural killer cells (Hafen, Brent Q., et al. Mind/Body Health. p 550-560. MA: Simon & Schuster, 1996). Our immune system is thus strengthened and we are less susceptible to infections.
At the University of Maryland, it was also discovered that laughter promotes blood circulation, significantly reducing the risk of cardiovascular disease and arteriosclerosis.
All in all, enough reasons to laugh more often!
