Science explains why we kiss the human world

Why does the kiss feel good? Watch this video to find out why people are attracted to get up.

You kiss your romantic partner, children and even pets, but why? Educational YouTuber Joe Hanson from the It’s Okay to be Smart series explains in this video.

The kiss is intensely sensory. Human lips are made for kissing; they have more nerves than any other part of your body.

Kissing releases endorphins (natural chemicals that feel good) and internal stimulants that send extra oxygen to your brain. At the same time, kissing lowers the stress hormone cortisol.

Henson goes on to explain that 90 percent of all human cultures kiss. We have records of kisses dating back 3,500 years. So kissing is part of our human heritage. It is a complex biological act, it cements relationships and it is good for you.
