Mummies are wrapped in bandages because bandages help prevent corrosion and protect the remains. A mummy is a kind of processed remains, usually made after death. In the process of mummification, it is necessary to take out the organs and tissues of the remains, and then dehydrate them or preserve them with salt or other substances. Bandages can help protect the remains from external damage, and also prevent the loss of salt or other substances on the remains. In addition, bandages can also play the role of beautification and decoration, making mummies more mysterious and ceremonial. In different cultures and historical periods, the colors, materials and winding methods of bandages are also different, reflecting the culture and customs at that time. Therefore, the reason why mummies are bandaged is to preserve and protect the remains, but also to beautify and decorate them.
