Nudity (or nakedness) is when a human is not wearing clothing.
Humans evolved to be mostly hairless. All other primates have fur. Modern humans evolved about 300,000 years ago, and continued to be naked until they made the first clothing, 100,000 years ago. Before clothing, humans decorated their bodies with jewelry, paint, tattoos, and scars. They made belts and bags to carry tools. They made masks and disguises to be less visible while hunting. When they moved out of Africa, people used the same crafts to make things to cover their bodies. They did this to both protect them from the cold and also to protect them from the dust and sun of the desert. Humans wear decorations and clothes as nonverbal communication. It shows their personality and group membership. In the modern world, there can many rules about nudity. Traditional Jewish, Christian, and Muslim people dress modestly. They are never without clothes in places where other people can see them. This may not include their spouses or family members of the same gender. Someone might be embarrassed for being seen naked.
Naturists believe being nude is good for health and well-being.[1] Nudity might be a normal part of life in places like the Netherlands, Scandinavia, Japan, and Germany. [2]
