According to statistics, 66 percent of people close their eyes when kissing. And only 34 percent of people enjoy watching their partners react during a kiss. In order to explain the reason for this, scientists have conducted research.
As a result, it turned out that a person who covers his eyes when kissing, without realizing it, protects his body from overload. During a kiss, a huge explosion of emotions occurs in a person's brain, which, if not restrained, can result in a swoon from an overabundance of feelings. Thus, kissing with closed eyes, a person subconsciously blocks the excess intensity of passions, which protects himself from unpleasant surprises.
