When body temperature rises, a center in the brain initiates physiological changes to decrease the body temperature. this is an example of negative feedback.
Further explanation
A normal human's body temperature is 37°C. A center in the brain initiates physiological change to help maintain our body temperature is called hypothalamus. The main job of the hypothalamus is to maintain homeostasis and to control certain hormones.
When we are exercising, the hypothalamus senses that you are too hot, then it sends signals to your sweat glands to make you sweat and cool you off. When the hypothalamus senses that you are too cold, it sends signals to your muscles that make you shiver and create warmth.
Maintenance of homeostasis usually involves negative feedback loops. Negative feedback is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus.
On the other hand, positive feedback loops are usually found in processes that need to be pushed to completion, for example in the process of childbirth. The neurons send a signal that leads to release of the hormone oxytocin from the pituitary gland. The positive feedback continues until the baby born.
