Head shrinking refers to the practice of reducing the size of a person's head, often associated with certain cultural rituals or historical practices. This process typically involves the removal of the skull and the use of various techniques to preserve the skin and facial features, resulting in a smaller, shrunken head. The most famous example of head shrinking comes from the Jivaroan tribes of the Amazon rainforest, particularly the Shuar people. They believed that shrinking the heads of enemies would capture their spirit and prevent them from seeking revenge. This practice has largely ceased, but it remains a topic of fascination in anthropology and popular culture.
