Physiological Stressors

Meaning

Physiological stressors are any internal or external factors that disrupt the body’s homeostatic balance, thereby triggering an adaptive response from the neuroendocrine and immune systems to restore equilibrium. These can range from acute challenges like intense exercise, injury, or infection to chronic conditions such as poor sleep, nutritional deficiencies, or persistent low-grade inflammation. The body’s capacity to appropriately respond to these stressors is a core determinant of overall health and resilience.
