National Nude Day is observed on July 14, 2022. It’s time to get naked, America: National Nude Day is a chance to keep cool on hot summer days. Nudity or nakedness is the state of wearing no clothing. The wearing of clothing is exclusively a human characteristic. The amount of clothing worn depends on functional considerations and social considerations.
A society's attitude to public nudity varies depending on the culture, time, location and context of an activity. There are many exceptions and particular circumstances in which nudity is tolerated, accepted or even encouraged in public spaces. Such examples would include a nude beach, within some intentional communities (such as naturist resorts or clubs) and at special events.
While some European countries such as Germany are rather tolerant about public nudity, in many countries public nudity may meet social disapproval or even constitute a misdemeanor of indecent exposure. In many countries public nudity is forbidden outright on the basis that nudity is inherently sexual. Many states of the United States fine offenders on that basis.
In many contexts, public nudity has been more accepted, especially at designated areas such as nude beaches and, even in the United States, e.g. during World Naked Bike Ride events or Bay to Breakers. In some states, such as Oregon, public nudity is legal and protected as free speech, as long as there is not the "intent to arouse". (With material from: Wikipedia)
