1. Kissing increases blood flow. Believe it or not, our lips are hypersensitive — nearly 200 times more sensitive than our fingertips, according to Women's Health Magazine. When we are engaged in a hot make out session we stimulate those nerve endings, which leads to increased blood flow to certain areas that promote our sexual arousal.

2. Kissing kickstarts the adrenal glands. Your adrenal glands can actually sense the excitement within your body. They unleash a rush of adrenaline, which can lead to increased heart rate, heavy breathing, and even sweaty palms! It is even estimated that kissing can burn up to 100 calories!

3. Kissing triggers the release of chemicals in the brain. The stimulation of the nerve endings in our lips that occurs when we kiss leads to the transmissions of signals back to our brain's cortex. These signals trigger the release of neurotransmitters, which give us that warm, fuzzy feeling that we associate with falling in love. One of the neurotransmitters that is released in dopamine, which regulates our feelings of pleasure and motivation to take part in enjoyable activities (like sex). Endorphins also swamp our system, and these little buggers are known for their ability to relieve pain and activate feelings of euphoria and elation. Our pituitary gland also releases oxytocin, or the "love hormone" into our bodies as well. This hormone encourages us to bond with our partner and create an emotional attachment to them.

Kissing serves as a mood-booster. Our bodies release serotonin and phenylethylamine during that particularly heated lip locking session, which can actually spark feelings of happiness and giddiness. Chemistry aside, kissing can boost our self esteem and reduce any pent-up tension we may be carrying around.
