Overtime, science has proven that kissing is even healthier than handshakes!
According to a recent scientific report by DailyMail, kissing helps partners share millions of bacteria, shoring up their immune systems and enabling them to better fight disease, they said. As 80 million bacteria are transferred from mouth to mouth in a single ten-second kiss, some people might brand the act ‘unhygenic’ but scientifically, this is not the case. In fact, experts claim that you’re more likely to become ill after far less intimate contact, such as shaking someone’s hand.
Philematologists aren’t exactly sure what originated kissing in the first place. The most likely theory is that it stems from primate mothers passing along chewed food to their toothless babies. The lip-to-lip contact may have been passed on through evolution, not only as a necessary means of survival, but also as a general way to promote social bonding and as an expression of love.
But kissing is not all about the romance! It is believed that kissing helps transfer critical information, rather than just meat bits. The kissing we associate with romantic courtship may help us to choose a good mate, send chemical signals, and foster long-term relationships, all of which is important for successful procreation.
Kissing allows us to get close enough to a mate to assess essential characteristics about them, none of which we’re consciously processing. Part of this information exchange is most likely facilitated by Pheromones, chemical signals that are passed between animals to help send messages. Animals use pheromones to alert their peers of things like mating, food sources, and danger, and researchers hypothesize that pheromones can play a role in human behavior as well. Although the vomeronasal organs, which are responsible for pheromone detection and brain function in animals, are thought to be vestigial and inactive in humans, research indicates we do communicate with chemicals.
Our first experiences with love and security usually involve lip pressure and stimulation through behaviours that mimic kissing, like nursing or bottle feeding. These early events lay down important neural pathways in a baby’s brain that associate kissing with positive emotions that continue to be important in throughout his life.
A kiss is packed with sensitive nerve endings so even the slightest brush sends a cascade of information to our brains, which can feel very good.
Kisses work their magic by setting off a whirlwind of neurotransmitters and hormones through our bodies that influence how we think and feel.We may not exactly be thinking about parenthood when we connect with someone at the lips, but kissing provides clues to help us decide whether to take a relationship further as Sheril Krishenbaum writes in her book “The science of kissing” :
“Because a kiss brings two individuals together in an exchange of sensory information by way of taste, smell, touch, and possibly even silent chemical messengers called pheromones (odorless airborne signals), it has the potential to provide all kinds of insight into another person. So even when our conscious minds may not recognize it, the act can reveal clues about a partner’s level of commitment and possibly his or her genetic suitability for producing children”
The first study to indicate that chemical signals play a role in attraction was conducted by Claud Wedekind over a decade ago. Women sniffed the worn t-shirts of men and indicated which shirts smelled best to them. By comparing the DNA of the women and the men, researchers found that women didn’t just chose their favorite scent randomly. They preferred the scent of man whose major histocompatibility complex (MHC)—a series of genes involved in our immune system—was different from their own. Having a different MHC means less immune overlap and a better chance of healthy, robust offspring. Kissing may be a subtle way for women to assess the immune compatibility of a mate, before she invests too much time and energy in him. Perhaps a bad first kiss means more than first date jitters—it could also mean a real lack of chemistry.
Well science will go on and on but the beautiful part of kissing is–when the craving creeps in, you don’t have to worry about science. Just close your eyes, and let the romance take over!
