Why Do We Kiss? The Science Of The Smooch
By Divine Caroline. Posted on .
Whether we live in a place where kissing is reserved for close acquaintances, or somewhere where a casual greeting means a one, two, or three cheeker, one thing does remain highly consistent: the side to which people turn while kissing. It’s almost always to the right. A 2003 study published in Nature found that twice as many adults turn their heads to the right rather than the left when kissing. This behavioral asymmetry is thought to stem from the same preference for head turning during the final weeks of gestation and during infancy.
One of the best things about kissing, however, is that we don’t have to think about any of this. Just close eyes, pucker up, and let nature takes its course.
