Why do people like being naked?
The reason I think people feel better when naked is because naked is the state that we are created in. God created Adam and Eve naked without shame (Genesis 2:25). And, as babies, we come into the world naked.
We don’t live in the Garden of Eden anymore, and we’re not babies anymore. But I think people see being naked as a reminder of those simpler times. That would explain why people feel a sense of peace while naked, or feel sad about having to put on clothes again. Because, while naked, a person feels more like their, for lack of a better term, “true self,” and clothes hide that “true self.” Clothes implicitly say “Who you naturally are must be hidden.” And so people feel a sense of relief and freedom when they don’t have to hide anymore. People can take off their clothes and say, with certainty, “This is me.”
The reason we wear clothes is so that people won’t be as tempted to see each other as objects for their enjoyment, not as human beings.
…they realized they were naked; so they sewed fig leaves together and made coverings for themselves. (Genesis 3:7)
But: Despite the imperfect world we live in, the naked human body is still inherently “very good.” (Genesis 1:31)
