Homeostasis Example: Body Temperature Regulation in Humans

One example of homeostasis in biology is the regulation of body temperature in humans. The human body maintains a relatively constant internal temperature of around 98.6°F (37°C) despite external temperature fluctuations. When the body gets too hot, such as during exercise or exposure to high temperatures, the body activates mechanisms to cool down. These mechanisms include sweating and the dilation of blood vessels near the skin's surface to release heat. Conversely, when the body gets too cold, such as in cold weather conditions, the body activates mechanisms to warm up. These mechanisms include shivering, which generates heat, and the constriction of blood vessels near the skin's surface to conserve heat. Overall, the body's ability to regulate its temperature within a narrow range is an example of homeostasis.
