Naturism is a form of collective practice of nature in a state of nudity associated to respect for the environment and other people. It developed early in Germany and in Protestant countries of northern Europe where nature has a mythic value. Nudism has become common even in public spaces such as beaches or urban parks. In Germany, naturist centres exist in all the country, though there are fewer in the East, so nude leisure may be enjoyed throughout the year. In France, they are concentrated in touristic, sunny regions. However, recent trends of naturism show a spread of the German model in Europe.
