negative feedback loop
If you've been sitting in the hot Sun and start to sweat, your body responds from a negative feedback loop.
Negative feedback loop is a reaction that takes place in response to some certain stimulus and it causes an opposite output or a decrease in function. The negative feedback loop generally tends to stabilize or maintain the system and minimizes the impacts of disturbances. All negative feedback loops occur in various phases and it involves a stimulus, a sensor, a control and an effector.
