Negative feedback

Negative feedback is a process in systems where a change triggers a response that counteracts that change, helping to maintain stability. For example, in the human body, when blood sugar levels rise after eating, the pancreas releases insulin to lower it back to a normal level. This balancing act is crucial in many areas, including biology, engineering, and climate control, where a system seeks equilibrium by reducing any deviation from a set point or desired state. In essence, negative feedback works to keep things steady and functioning smoothly.
