Why Do We Kiss? The Hidden Meanings of a Smooch
Kissing is a universal expression of love💓, affection, and desire that is present in almost every culture on the planet. It can be used to say hello and goodbye, express deep emotions, or simply enjoy being close to someone.
Scientists have been studying the origins and science behind kissing for decades, and their findings are fascinating. One theory suggests that kissing evolved from the practice of "kiss-feeding," where mothers would feed their young mouth-to-mouth, much like birds feeding worms to their chicks. This may have led to the association between pressing lips and love. Since the way to most people’s hearts is through their stomachs 😁.
Interestingly, kissing is not unique to humans. The bonobo ape, our close genetic cousin, also kisses as a form of social behaviour and comfort. This suggests that kissing may be ingrained deep in our DNA, as it is a behaviour shared by our evolutionary ancestors.
But what exactly happens in our bodies when we kiss?🤔 Kissing💏 stimulates the release of neurotransmitters and hormones like oxytocin, dopamine, and serotonin, which are also involved in our relationships. Oxytocin, for example, is known to promote feelings of closeness, intimacy, and security. It also burns calories, so the more passionate the kiss, the greater the metabolic boost!
fever, and tooth decay. This means that it can be a small but significant health risk. Despite this, approximately 90% of cultures kiss, suggesting it is a basic human instinct.
In conclusion, kissing is a complex and fascinating behaviour that is deeply ingrained in our biology and culture. It can bring us closer to our loved ones, boost our metabolism, and even strengthen our immune system. So the next time you kiss someone, remember there's much more going on than just pressing your lips together!
