Nearly everyone enjoys kissing, but most of us rarely stop to wonder why. The answer is deeply rooted in our biology.
- One of the first physically enjoyable sensations we experience is being nursed by our mothers; the use of our lips comes naturally to us. Nursing is very comforting for a baby. It usually takes place in a safe and calm environment, so the baby grows to associate soft press.
- Also, Do you know why we use the letter “x” to represent kissing? There’s a historical reason behind it.
Throughout history, humans have used kissing for many different purposes. In the Middle Ages, it was often used to seal a contract.
The spot on the contract that was to be kissed by the concerned parties was marked with an “x”, just like we use “x’s” for kisses in online chats today. We’ve been representing kissing in this way for hundreds of years.
- Kissing is healthy and makes you feel high. It decreases our levels of cortisol, the “stress hormone” that increases your blood pressure and weakens your immune system. Chronically high levels of cortisol are dangerous and contribute to problems like heart disease, so anything that lowers your cortisol is good for you.
It also increases the levels of serotonin, and dopamine, the euphoric hormones, and oxytocin, the “love hormone” or “bonding hormone”.
- Different rulers and governments tried to outlaw kissing for health reasons, such as during the Great Plague in London in 1665. In fact, a law in South Africa tried to ban children under 16 from kissing as recently as 2008, in a misguided attempt to curb the spread of HIV.
The Catholic Church tried to ban kissing several times for moral reasons and because it can lead people toward having s*x. None of their attempts were successful, however; kissing is a natural part of who we are.
