Stress produces numerous physical and mental symptoms which vary according to each individual's situational factors. These can include a decline in physical health, such as headaches, chest pain, fatigue, sleep problems, [1] and depression. The process of stress management is a key factor that can lead to a happy and successful life in modern ...
Stress management encompasses techniques intended to equip a person with effective coping mechanisms for dealing with psychological stress, with stress defined as a person's physiological response to an internal or external stimulus that triggers the fight-or-flight response. Stress management is effective when a person uses strategies to cope ...
The stress response system thus has its role as an adaptive process to restore homeostasis in the body by actively making changes. [4] [5] For instance, the body will involve in an endocrine system response in which corticosteroids are released. This process is known as allostasis, first proposed by Sterling and Eyer (1988). [6]
[107] [108] Though stress is discussed throughout history from many distinct topics and cultures, there is no universal consensus over describing stress. [109] This has led to multiple kinds of research, looking at the different aspects of psychological stress and how it changes over a lifespan.
A study about stress effects on female songbird’s response to sexual signal for mating indicated that the response to this specific signal can be impaired if the female is exposed to developmental stress. Behavioural changes as a result from developmental stress impairs neural responses to sexual signals, which reduces mating. [5]
A typical example of the stress response is a grazing zebra. If the zebra sees a lion closing in for the kill, the stress response is activated as a means to escape its predator. The escape requires intense muscular effort, supported by all of the body's systems. The sympathetic nervous system's activation provides for these needs. A similar ...
(A stressor is a chemical or biological agent, environmental condition, external stimulus or an event seen as causing stress to an organism.) Selye initially (c. 1940s) called this the "general adaptation syndrome" (at the time it was also called "Selye's syndrome"), but he later rebaptized it with the simpler term "stress response".
