Homeostasis maintained by negative feedback is a process in which a change in a physiological variable triggers a response that counteracts the initial change, bringing the variable back to its set point. In this example, the release of sweat by the eccrine glands cools down the body and brings the body temperature back to its set point. This is an example of negative feedback because the response (sweating) opposes the initial stimulus (increase in body temperature).
