Humans get angry for all kinds of reasons and we also kiss for many other reasons, for love, luckily, to say hello and goodbye, simply because we feel like it …
And when you stop and really think about the act of kissing, it’s kind of funny, right? Press your lips against another person and, in some cases, exchange saliva? It may seem like strange – albeit nice – behavior, but it also has a lot of science behind it.
There are many theories about how the kiss originated and why we kiss. Some scientists believe that kissing is a learned behavior, as approximately 10% of humans do not kiss and fewer still kiss with romantic or sexual intent. Others believe that kissing is instinctive and rooted in biology.
Kissing triggers a chemical reaction in the brain, including an explosion of the hormone oxytocin, which we know as the “love hormone,” as it awakens feelings of affection and attachment.
According to a 2013 study,oxytocin is particularly important in helping men bond with a partner.Women, curiously, experience a ‘flood’ of oxytocin during labor and breastfeeding, strengthening the mother-child bond.
Speaking of food,many believe that kissing comes from the practice of kiss feeding.Like the birds that feed their chicks, mothers used to feed their children chewed food, and some still do.
Some kisses are rooted in romantic love.
With the arrival of a new love appears the effect ofdopaminein the reward pathway of your brain. This hormone is released when you do something that makes you feel good, such as kissing and spending time with someone you are attracted to.
As for more intimate and pleasant kisses, those that are given with the mouth open and with the tongue are especially effective in increasing the level of sexual arousal, since they increase the amount of saliva produced and exchanged. The more saliva exchanged, the more excited we will feel. Yes indeed,Let’s not forget to practice good oral hygiene for a fresh, kiss-worthy mouth.
