Thermoregulation

In the winter, people wear thicker, warmer clothing to stay warm. In the summer, people wear thinner, lighter clothing and to stay cool.

Thermoregulation is one form of homeostasis, where an organism adapts to the temperature of its surroundings. If the environment is warmer than the body temperature of the organism, the organism can transfer its heat externally to cool off through conduction, convection, radiation, or evaporation. If the environment is cooler, the organism can take in heat internally to become warmer through conduction or convection. Examples: wearing a jacket in the winter, shivering, hair lifting upright, sweating, and panting.
