4.7. Climatic Adaptation

Humans and many other mammals have unusually efficient internal temperature regulating systems that automatically maintain stable core body temperatures in cold winters and warm summers. In addition, people have developed cultural patterns and technologies that help them adjust to extremes of temperature and humidity. Less massive individuals are more often found in warm climates near the equator, while those with greater bulk, or mass, are found further from the equator in colder regions. This is due to the fact that big animals generally have larger body masses which result in more heat being produced. People living in cold climates prefer drinking alcohol as it increases blood flow to the body extremities, thereby providing a feeling of warmth. With the help of technology, researches are able to stay throughout the year in extremely cold Antarctica and Arctic regions. People are able to live in extremely hot climate of tropical region by using air conditioners.
