Tribal women from the Amazon River Basin in South America often bath and swim in order to cool off from the extreme heat of the tropical rainforest.  In addition, the meticulous personal hygiene of tribal women and girls helps them maintain their health in a harsh environment.  Note the use of gourds as water containers indicating that these indigenous women are still living traditionally and not contaminated by the influence of western goods and culture.  Tribal women are not modest or ashamed of their bodies as are many westerners.  At one time, virtually all the tribal women of the entire Amazon River Basin wore no clothes.
