A ten second passionate kissing makes lovers or partners share about 80 million bacterias. This report was compiled by scientists in Netherlands. The science behind this behavior reveals that along with all of those germs, we share plenty of benefits with a partner.
Our lips are the body’s most exposed parts. Unlike in other animals, human lips are uniquely everted. They are packed with sensitive nerve endings so even the slightest brush sends a cascade of information to our brains, which can feel very good. Kissing activates a very large part of the brain associated with sensory information because when you kiss you are technically at work thinking of what to do next especially men hence the magic sets off a whirlwind of neurotransmitters and hormones in our bodies that influence how we think and feel.
If there’s real “chemistry” between two people, a kiss can set the stage for a new romance. A passionate kiss puts two people in very close proximity – nose to nose. We learn about each other by engaging our sense of smell, our taste buds and sense of touch. And through that information all sorts of signals are being sent to our brain informing us about the other person. In fact, the scent of man can provide subconscious clues about his DNA to his partner.
59% of men and 66% of women say they have ended a budding relationship because a kiss didn’t go well. This was concluded by Evolutionary psychologists at the State University of New York at Albany. Research by Swiss biologist Claus Wedekind found that women are most attracted to the scents of men who carry a different genetic code for their immune system in a region of DNA known as the major histocompatibility complex or MHC.
Scientists suspect that when a couple who carry distinctly different genetics for fighting disease, their children are likely to benefit by having a strong immune system. 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.
Kissing also sets off a cascade of neural impulses that bounce between the brain and the tongue, lips, facial muscles, and skin. Billions of little nerve connections distribute information around the body, producing chemical signals that change the way we feel. A passionate kiss can spike the neurotransmitter dopamine, which is linked to feelings of craving and desire. Oxytocin, known as the “love hormone,” fosters a sense of closeness and attachment. Adrenaline boosts our heart rate and can make us start sweating as our bodies begin to anticipate what might occur later. Cortisol, known as the stress hormone, also dips to reduce uneasiness. Blood vessels dilate, breathing can deepen, cheeks flush and our pulse quickens reports IFLScience.
I thought kissing is just something we do for fun, but who knew it involves many scientific procedures that can not be understood by two simple lovers practicing the art of kissing or the science of kissing? Science has just proved that there is more to kissing than what meets the eye and lips, so next time you kiss remember to put down notes.
