Kissing is much more than just a demonstration of affection. A kiss is an evolutionary form of bonding. The scientific study of kissing is called Philematology. It comes from Philos in Greek which means earthly love!

Believe it or not the exchange of saliva has many health benefits.
It keeps your teeth healthy. Saliva is packed with minerals that make it a powerful antibacterial agent. Somebody probably told you to lick your wounds at one point in your life. It makes sense since saliva is a natural antiseptic.
It burns calories. The act of kissing can involve between 2 and 34 facial muscles and burns up to 26 calories per minute!
A small kiss can transfer between 10 million and 1 billion bacteria which can help fight infections. The bacteria you exchange can boost your immune system.
Your brain gets more oxygen. Since your heart pumps faster your blood vessels dilate and blood travels faster to your organs oxygenating them.
Kissing can reduce cortisol levels which is the stress hormone, therefore, making you feel more relaxed and happy.
