Fatigue: What Is Stress?
Homoeostasis, is a mechanism within the body that keeps physiological processes functioning optimally. Stressors, are external events which essentially alter the processes in some form. For example, the weather becomes really hot and you begin to sweat. The stressor here is the heat, the homeostatic response is the body producing sweat to act to cool the body down. The human body is an amazing thing, constantly changing and adapting to the external environment to contain and preserve its internal well-being.
