Mud helps suffocate parasites and lice and also serves as a natural sun block to keep the hot sun off of the bodies of rhinos and pigs. It is a biothermal response to their lack of ability to dissipate heat; they immerse themselves in the mud if there is not a large round tub of cool water for them to bathe themselves in or if it is too dry for any mud to be found. Pigs do not have any sweat glands; therefore they cannot sweat. Rolling in mud cools them down.
