The benefits of kissing? For one, kissing boosts immunity.

We know kissing as a social pleasantry, a potential ending to a date and a means of connecting with our main squeeze. The collision of lips and tongues that we often take for granted has a whole lot more bubbling under the surface than meets the eye and actually does a body very, very good. Kissing has long been thought to be a way to pass along bugs and strengthen the body’s defences. 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.

Speaking of calories, here’s how many you can burn while sleeping.

Passionate kisses are good for your oral health

According to Mark Burhenne, DDS, founder of, and the author of The 8-Hour Sleep Paradox, kissing supports good oral and dental health in a few ways. One is that kissing is one of the few ways to share a good microbiota, according to Dr. Burhenne. “If your oral microbiome isn’t all that diverse or healthy, exchanging saliva with a partner who does have a healthy oral microbiome may be the trick you need to improve the health of your own,” he says.

Kissing helps you pick the best mate

Anthropologist Helen Fisher describes kissing as a “mate assessment tool.” 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. It is built to pick up the most sensitive feelings—the most intricate tastes and smells and touch and temperature. And when you’re kissing somebody, you can really hear them and see them and feel them. So kissing is not just kissing. It is a profound advertisement of who you are, what you want, and what you can give.

Other researchers note that kissing is biology’s way of determining who in nature you are most genetically compatible with. “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.

There’s nothing like a good smooch after a long, stressful day. In addition to releasing a surge of the relaxing hormone oxytocin, kissing has also been linked to a decrease in the stress hormone cortisol. It can also boost levels of serotonin, which leads to feelings of calm and contentedness.
