Does cinematic viewing evoking laughter improve endothelial function compared to mental stress?
This study investigates the comparative effects of mental stress versus laughter induced by cinematic viewing on endothelial function.
May suggest laughter modulates endothelial function differently than stress; hypothesis-generating and requires prospective validation before clinical consideration.
hronic life stressors such as depression, anxiety, hostility, and anger may contribute to increased risk of coronary heart disease, 1 in part by impairing endothelial function. 2 3 Although coronary heart disease may also be associated with attenuated positive emotions as shown by reduced situational humour, 4 little if any information is available regarding the potential impact of positive emotions on vascular reactivity. Because cinematic viewing evokes a range of negative and positive emotions, the present study was designed to compare the effect of mental stress versus laughter on endothelial function.
