Human Variation and Race
Human Variation and Race Cold is an environmental stress that negatively impacts humans homeostasis. Our bodies react negatively to a change of temperature that's very different from our bodies. Specifically in cold, there is a constant threat of hypothermia. This results in humans having to adapt against the cold, or the end result could be death. Short term: One adaptation is to start shivering. This automatically warms up the body to keep the blood circulation within all parts of the body. Facultative: People living in colder climates will often eat fattier, high dense foods, resulting in a faster metabolism. Developmental: Over the course of several generations, it's seen that many people who live in cold climates have more blood in their bodies than those who have lived in the heat. They also develop body changes, including often becoming more compact, with shorter limbs and often being shorter and stouter than those in a warm climate. Cultural: One of the cultur
