Can Eating Chocolate Feel Better Than a Kiss?
The heart rates and brain activity of couples in their 20s was monitored while they first melted chocolate in their mouths, and then kissed. The "buzz" caused by chocolate was more intense, and lasted four times longer, than that caused by kissing.
Chocolate also doubled volunteers’ heart rates, from a resting rate of about 60 beats per minute to 140. Kissing did increase heart rate, but not to the same degree.
Substances in chocolate are already known to have a psychoactive effect; it contains phenylethylamine, which can raise levels of endorphins in the brain, and caffeine, which is stimulating.
Allowing the chocolate to melt on your tongue may maximize the buzz.
