Nudism, or naturism, is the practice of going nude or unclothed in social and usually mixed gender groups, specifically in cultures where this is not the norm. It sometimes occurs furtively in secluded places in countries where appearing naked in public is illegal, but enjoys widespread acceptance in other areas of the world. Those who practice nudism are called nudists or naturists. Nudism is a way of life in harmony with nature characterised by the practice of social nudity, with the intention of encouraging self-respect, respect for others and for the environment. It is also known as naturism.
