Here are a few of the medical benefits of smooching, according to a list published by the Huffington Post:
-Kissing stimulates saliva production, which washes harmful bacteria off the teeth.
-It's not exactly a workout, but locking lips burns a few calories, about two to six per minute.
-Kissing boosts immunity by exposing you to others' germs -- as long as they aren't the wrong kind of germs.
-One study found smooching eases stress by releasing cortisol in the body, which is a sign of relaxation.
Finally, kissing might ease sniffling and sneezing. A Japanese study showed people who kissed for 30 minutes lowered proteins that trigger allergy symptoms.
