The Science Behind Why We Close Our Eyes When We Kiss

Closing our eyes when we kiss is all in the brain, and has nothing to do with love, lust or passion.

In a research published in the Journal of Experimental Psychology: Human Perception and Performance, psychologists found out that people close their eyes when they kiss because the brain cannot handle the high and sometimes complex visual demand and tactile sensation of the activity effectively.

The more visual data the brain has to process, the lesser is the awareness to stimuli.

The importance of this study is more significant when one thinks about the
tactile warning systems in cars, stairs, curb ramps, and pavers that are meant to notify a person if they are about to collide with something.

If people are bombarded with complex or too much visual information like when looking at the road when driving, they may be less perceptive of these warnings.
