This idea of nudism was not

This is how Heinrich Ingevitter justified the idea of nudism at the end of the 19th century in his book "Nudity".

This idea of nudism was not new, since even in Ancient Sparta, all participants in sports competitions were naked.

Philosophers who brought the scientific basis for the phenomenon of nudism argue that the naked human body becomes closer to nature and the feeling of this proximity strengthens the body and, most importantly, gives a sense of inner freedom.
