thermal insulating properties of hair pigmentation
Pelt
All mammals have some hair, but cetaceans, sirenians, elephants, domestic pigs, naked mole rats, hippopotamuses, rhinoceroses, walruses, sea lions, some seals, and others lack dense, inslulating body hair. Humans' body hair is not very dense either. Thus, hair is a characteristic of mammals, but dense hair covering the entire body is not.

Characteristics such as hair color and height are called phenotypes. Phenotypes are determined by the make up of alleles in the body, known as genotypes.
Your body heat does not get transmitted away from your body as readily in a dry air environment. When water comes into contact with your skin, the thermal transfer characteristics of your body heat into the environment are greatly increased.
