Kissing has long been thought to be a way to pass along bugs and strengthen the body’s defenses. In fact, a study reported in the journal Medical Hypotheses says kissing may increase a woman’s immunity from Cytomegalovirus, which can cause infant blindness and other birth defects if the mother is a carrier during pregnancy.

Depending on different reports, smooching burns anywhere from two to six calories per minute. Not quite a jog on the treadmill, but locking lips for an hour may burn off half a handful of M&Ms or half a glass of wine. Hey, it’s something.

Much of the cortex is devoted to picking up sensations from around the lips, cheeks, tongue and nose. Out of 12 cranial nerves, five of them pick up data from around the mouth. “At the moment of the kiss, there are hard-wired mechanisms that assess health, reproductive status and genetic compatibility,” says Gordon G. Gallup Jr., a professor of evolutionary psychology at the State University of New York at Albany who studies reproductive competition and the biology of interpersonal attraction. “Therefore, what happens during that first kiss can be a make-or-break proposition.” No pressure, though.

According to Dental Health Magazine, "deep kissing increases the flow of saliva, which helps to keep the mouth, teeth and gums healthy."
