Ever wondered why it is that when you lean in for a kiss, you're meant to close your eyes? Or why it's considered such bad form to sneakily open your eyes mid-makeout?
You see, psychologists Polly Dalton and Sandra Murphy published a study in the Journal of Experimental Psychology: Human Perception and Performance. Through that study, they discovered that it's really, really hard for our brain to focus on our other senses if we've got any visual stimuli to distract us. As a result, we need to close our eyes when we kiss so that we can actually enjoy how it feels physically.
Dalton and Murphy discovered this by getting together some participants and asking them to do different letter-searching tasks. While they did this, a small vibration was applied to the participants' hands.
The researchers found that when the participants were doing trickier letter-searching tasks, they didn't feel the vibrations as strongly—because their eyes were busier and their brains were focused on that.
So when we kiss, it's the same deal. It just won't feel as good with your eyes roaming about and getting distracted from the other sensations at hand.
Plus, staring at the other person's closed eyes throughout is bloody creepy. Don't do that.
