A stressor is a chemical or biological agent, environmental condition, external stimulus or an event seen as causing stress to an organism. [1] Psychologically speaking, a stressor can be events or environments that individuals might consider demanding, challenging, and/or threatening individual safety.
Stressors are more likely to affect the health of an individual when they are "chronic, highly disruptive, or perceived as uncontrollable". [10] In psychology, researchers generally classify the different types of stressors into four categories: 1) crises/catastrophes, 2) major life events, 3) daily hassles/microstressors, and 4) ambient stressors.
Chronic stressors may not be as intense as acute stressors such as natural disaster or a major accident, but persist over longer periods of time and tend to have a more negative effect on health because they are sustained and thus require the body's physiological response to occur daily. [14]
With persistent exposure to toxic stressors like cigarette smoke, heavy metals, or chronic emotional strain, this waste may weaken the cells and cause proteins to misfold, which could eventually ...
“Even though exercise is healthy for us, it is a stressor to all of our systems and more intense energy-expensive exercise is a bigger stressor than lower intensity exercise,” says Rachelle ...
The system is arguably a protective defense against threats [5] and usually does not pose a health risk. [7] 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]
This is linked to the added stressors and challenges surrounding chronic illnesses, the effects of medications on mental health and chemical changes that can take place in the brain related to ...
They are maladaptive, biological and psychological responses to short- or long-term exposures to physical or emotional stressors. The National Institute of Environmental Health Sciences categorizes Obsessive-Compulsive Disorder (OCD) and Post-Traumatic Stress Disorder (PTSD) as stress-related disorders. [1]
