First what is stress?
Physiological or biological stress is our bodies response to a stressor such as an environmental condition.
An event that triggers the stress response may include:
- environmental stressors (hypo or hyper-thermic temperatures, elevated sound levels, over-illumination, overcrowding)
- daily stress events (e.g., traffic, lost keys, quality and quantity of physical activity)
- life changes (e.g., divorce, bereavement)
- workplace stressors (e.g., high job demand vs. low job control, repeated or sustained exertions, forceful exertions, extreme postures)
- chemical stressors (e.g., tobacco, alcohol, drugs )
- social stressor (e.g., societal and family demands)
Stress means different things to different people. What causes stress in one person may be of little concern to another.
What can stress do to our body?
There is a connection between stress and illness.
Theories of the stress–illness link suggest that both acute and chronic stress can cause illness, and several studies have suggested such a link.
According to these studies, both acute and chronic stress can lead to changes in behavior and in physiology. Behavioral changes can include smoking, changes in eating habits and physical activity. Physiological changes can include changes in sympathetic activation or HPA activity, and immunological function.
The HPA axis regulates many bodily functions, both behavioral and physiological, through the release of glucocorticoid hormones. And glucocorticoids (GCs) are a class of corticosteroids.
Corticosteroids are a class of steroid hormones that are produced in the adrenal cortex of vertebrates.
Both glucocorticoids and corticosteroids (along with other hormones) are involved in a wide range of physiologic processes, including stress response, immune response, and regulation of inflammation, carbohydrate metabolism, protein catabolism, blood electrolyte levels, and behavior.
Stress can make the individual more susceptible to physical illnesses like the common cold.[4, 4*] Stressful events, such as job changes, may result in insomnia, impaired sleeping, and physical and psychological health complaints.
Chronic stress and a lack of coping resources available or used by an individual can often lead to the development of psychological issues such as delusions  depression and anxiety.
Chronic stressors that may not be as intense as an acute stressor like a natural disaster or a major accident, but they persist over longer periods of time.
These types of stressors tend to have a more negative effect on health because they are sustained and thus require the body's physiological response to occur daily.
This depletes the body's energy more quickly and usually occurs over long periods of time, especially when these microstressors cannot be avoided (i.e. stress of living in a dangerous neighborhood).
