FOX: Have you ever wondered why kissing feels so good?

Researchers from Lafayette College in Pennsylvania may have uncovered the answer. They found lip-locking actually sparks an increase of hormones in the brain.

Due to a series of complex chemical processes, those involved in kissing experience a combination of relaxation, excitement and love, according to the study.

However, men have a heightened awareness of these feelings, the study found, whereas women need a little extra ambience to reach the same state as men - like romantic music and dim lighting.

The researchers are not sure why these hormonal changes happen, but it may have to do with the swapping of pheromones in saliva.

The findings, based on an honors thesis project conducted by neuroscience graduate Carey Wilson, will be presented this week during the annual meeting of the American Association for the Advancement of Science in Chicago.

Wendy Hill, a professor of psychology at Lafayette, and neuroscience major Evan Lebovitz, who both continued research on the project, will join Wilson in presenting the project entitled, "The Science of Kissing."
