Nudity
The cultural division between northern and southern Europe can be traced to the sauna. Various methods of cleaning the body by wet or dry heat (causing sweating) are found worldwide. In Finland, almost everyone has access to a sauna. Sharing a sauna with others of all sexes and ages widens the definition of private nudity. Communal bathing breaks the connection between nudity and sexual activity, which is assumed by other cultures. Instead, modesty is in behavior, such as not calling attention to one's own body, and not staring at others.
