Hans Selye defined stress as “the nonspecific (that is, common) result of any demand upon the body, be the effect mental or somatic.” [5] This includes the medical definition of stress as a physical demand and the colloquial definition of stress as a psychological demand. A stressor is inherently neutral meaning that the same stressor can ...
Physiological stress represents a wide range of physical responses that occur as a direct effect of a stressor causing an upset in the homeostasis of the body. Upon immediate disruption of either psychological or physical equilibrium the body responds by stimulating the nervous , endocrine , and immune systems .
However, the problem arises when there is a persistent threat. First-time exposure to a stressor will trigger an acute stress response in the body; however, repeated and continuous exposure causes the stressor to become chronic. [4] McEwen and Stellar (1993) argued there is a "hidden cost of chronic stress to the body over long time periods". [8]
Rather than causing us to store anger in our back, or fear in our stomach, stress triggers a dynamic whole-body response—and it happens not just when people repress their emotions, but even if ...
The effects of stress on memory include interference with a person's capacity to encode memory and the ability to retrieve information.

In addition, consuming a fiber, protein, and antioxidant-rich diet, complete with fruits, veggies, and whole grains, can provide your body with fuel to conquer stress. 5. You're sick often.
Excessive stress and sleep deprivation can cause cardiovascular issues, such as high blood pressure and heart disease. In a study focusing on the impacts of chronic stress on the heart, it was found that during times of chronic stress, the body hyperactivates the sympathetic nervous system which leads to changes in heart rate variability. [22]
Selye argued that stress differs from other physical responses in that it is identical whether the provoking impulse is positive or negative. He called negative stress "distress" and positive stress "eustress". The system whereby the body copes with stress, the hypothalamic-pituitary-adrenal axis (HPA axis) system, was also first described by ...
