Watching comedy shows can improve cardiovascular risk factors, researchers have reported in the journal Psychosomatic Medicine.
The study of 18 healthy people found that arterial stiffness and central hemodynamics improved after watching a 30-minute section from the movie Naked Gun. Cortisol and von Willebrand factor levels also decreased with laughter, reported the team from Athens Medical School, Greece.
Watching stressful scenes, however, had the opposite effect: carotid-femoral pulse wave velocity increased after watching a 30-minute clip from Saving Private Ryan. Stressful viewing also lowered interleukin-6 levels, but did not affect fibrinogen or soluble CD40 ligand levels. [Psychosom Med 2009 Feb 27]
