Yahoo: Kisses unleash chemicals that ease stress levels
In an experiment, Hill explained, pairs of heterosexual college students who kissed for 15 minutes while listening to music experienced significant changes in their levels of the chemicals oxytocin, which affects pair bonding, and cortisol, which is associated with stress. Their blood and saliva levels of the chemicals were compared before and after the kiss.
Both men and women had a decline in cortisol after smooching, an indication their stress levels declined.
