Homeostasis is fundamentally maintained through the mechanism of negative feedback, which acts to stabilize physiological systems by countering perturbations as described in [1], [2], and [3]. This relationship is further supported by the cybernetic model of homeostasis, which relies on negative feedback loops to return variables to a setpoint [4], [5], and [6].

claimMedical education often characterizes homeostasis using a cybernetic model based on negative feedback involving a setpoint, which is considered a standard for physiological education.
perspectiveThe authors argue that the notion of homeostasis has been hindered by a narrowed account based on the cybernetic model of negative feedback to a setpoint, which equates health with balance and healing with returning to a normal state.
quoteModell et al. (2015, p. 261) define homeostasis as a system that operates in a way that causes any change to the regulated variable, a disturbance, to be countered by a change in the effector output to restore the regulated variable toward its set point value. Systems that behave in this way are said to be negative feedback systems.
claimThe cybernetic model of homeostasis, which relies on negative feedback to a setpoint, associates health with balance or stability and defines healing as returning to an initial or normal state after a perturbation.

claimHomeostasis is the result of complex interaction and competition between multiple negative and positive feedback systems and provides the basis for physiological regulation.
referenceThe article 'Homeostasis: The Underappreciated and Far Too Often Ignored Central Organizing Principle of Physiology' identifies physiology, homeostasis, internal milieu, Claude Bernard, Walter Cannon, control theory, feedback regulation (negative and positive), and cybernetics as key concepts.
7.8 Homeostasis and Feedback - Human Biology humanbiology.pressbooks.tru.ca 2 facts
claimHomeostasis maintenance involves feedback, defined as data that feeds back to control a response, which can be either negative or positive. While negative feedback is used by all feedback mechanisms that maintain homeostasis, biological examples of positive feedback are much less common.

Homeostasis vs. Allostasis: Why Your Body Needs More Than Stability trueself.health 1 fact
procedureThe homeostasis mechanism for regulating body temperature involves a negative feedback loop where sensors detect deviations from the 37°C (98.6°F) setpoint, the brain receives the signal, and the body executes corrective actions—such as shivering and constricting blood vessels when cold, or sweating and dilating blood vessels when hot—until the temperature returns to the setpoint.
Homeostasis or Allostasis? - Beauty, Neuroscience & Architecture neuro-architectology.com 1 fact
claimHomeostasis functions through negative feedback, a reactive strategy where the perturbation of a regulated variable away from its optimal value is detected, eliciting corrective responses to return the variable to pre-perturbation levels.

claimNegative feedback is a biological control mechanism where a system's output acts to reduce or dampen the processes that lead to that output, allowing the system to self-stabilize and maintain homeostasis.
