Sheril Kirshenbaum, the author of The Science of Kissing, notes that the anticipation to kiss someone can fire up one’s brain reward pathways.
Studies have revealed that more of the human brain tends to fire up during kissing than sex. The lips make the nerve ending zones to become around 200 times more sensitive to the happy feeling, more than your highly sensitive fingertips. This means that kissing has the ability to ignite a large section of the brain as you pick up each sensation.Kirshenbaum further argues that the more anticipation one feels leading up to kissing, the more increased dopamine experience you will get at the end of the process. The pleasure hormone released tends to energize the human brain and makes it more sensitive.As a result, a setting to absorb sensory information is established within your brain. When you kiss, you become wrapped in each other’s scent and the whole feeling will intensify the attraction. The personal chemicals will make or break a kiss. Both men and women are deeply in love with kissing as long as it is done in the right way and place. Women feel happier being kissed in public than men, another study revealed.
