- Stressors threaten the body’s ability to maintain physiologic homeostasis. The body responds to any change in internal conditions with reflexes designed to return itself to the previous state. Homeostasis is usually accomplished by activation of a negative feedback cycle.

Oct 17, 2020 · Stress constitutes a state of threatened homeostasis triggered by intrinsic or extrinsic adverse forces (stressors) and is counteracted by an intricate repertoire of physiologic and behavioral responses aiming to maintain/reestablish the optimal body equilibrium (eustasis).

A stressful situation — whether something environmental, such as a looming work deadline, or psychological, such as persistent worry about losing a job — can trigger a cascade of stress hormones that produce well-orchestrated physiological changes. A stressful incident can make the heart pound and breathing quicken. Muscles tense and beads of sweat...
The stress response begins in the brain (see illustration). When someone confronts an oncoming car or other danger, the eyes or ears (or both) send the information to the amygdala, an area of the brain that contributes to emotional processing. The amygdala interprets the images and sounds. When it perceives danger, it instantly sends a distress sig...
Many people are unable to find a way to put the brakes on stress. Chronic low-level stress keeps the HPA axis activated, much like a motor that is idling too high for too long. After a while, this has an effect on the body that contributes to the health problems associated with chronic stress. Persistent epinephrine surges can damage blood vessels ...

May 7, 2024 · Physiological stress: Physiological stress refers to the body's response to internal or external stressors that disrupt homeostasis. Examples include illness, injury, sleep deprivation, or nutritional deficiencies, which activate physiological stress pathways and compromise health and well-being.

Jun 27, 2019 · The human stress response has evolved to maintain homeostasis under conditions of real or perceived stress. This objective is achieved through autoregulatory neural and hormonal systems...
The importance of acknowledging the protective, as well as the potentially damaging effects of the mediators of stress and adaptation, has led to the introduction of two terms: “allostasis,” meaning the process of maintaining stability (homeostasis) by active means, namely, by putting out stress hormones and other mediators; and ...
