Sarah Pressman is an Associate Professor of Psychology and Social Behavior at the University of California, Irvine. She conducted a study to determine whether or not people who smile more behaved differently.
And the results are surprising: not only do smilers have a more proactive behavior towards healthcare -they are more likely to seek preventive healthcare-, but all smilers (even fake ones!) will produce more cortisol or catecholamines, anti-stress hormones that have real benefits on the immune system function, cardiovascular system, and can increase the pain threshold.
