Kissing decreases cortisol and increases oxytocin

February 8th, 2009 at 7:07 pm (Science Factini, love, molecules)

Today’s factini isn’t so surprising. Kissing makes us feel less stress (lower cortisol) and more bonded (higher oxytocin), reports psychologist Wendy Hill of Lafayette College. What is interesting: while kissing causes a cortisol decrease in both men and women, oxytocin is increased more in men than in women. The researchers assume that this has to do with environment. Women need a certain atmosphere.

The hormonal changes due to kissing may have to do with pheromones exchanged in saliva, but -for maximum efficacy - I wouldn’t recommend thinking about this during the act.

The Telegraph article states:

In 2007 British scientists measured the brain and heart activity sparked by passionate kissing, but found it was less intense that the stimulation produced by eating chocolate.

Uh-huh! That’s why this Dopamine Day, I have a date with some fine chocolate. I can’t wait to touch my lips to that sweet catch!
