Managing Stress

As a human being we always live with stress. Stress is not only bad things. Stress also could make us happy in a second.

Stress is a biological term which refers to the consequences of the failure of a human body to respond appropriately to emotional or physical threats to the organism, whether actual or imagined. It is "the outonomic response to environmental.

The term of "stress" itself was first used by the endocrinologist Hans Selye in the 1930s to identify physiological responses in laboratory animals. He later broadened and popularized the concept to include the perceptions and responses of humans trying to adapt to the challenges of everyday life. In Selye's terminology, "stress" refers to the reaction of the organism, and "stressor" to the perceived threat.

Stress in certain circumstances not only experienced negatively but could be experienced positively.

for example, Eustress can be an adaptive response prompting the activation of internal resources to meet challenges and achieve goals such as : meeting a challenge, coming in first or winning, getting a promotion in work, happy family and love

The term is commonly used by laypersons in a metaphorical rather than literal or biological sense, as a catch-all for any perceived difficulties in life. It also became a euphemism, a way of referring to problems and eliciting sympathy without being explicitly confessional, just "stressed out".
It covers a huge range of phenomena from mild irritation to the kind of severe problems that might result in a real breakdown of health. In popular usage almost any event or situation between these extremes could be described as stressful.

When give negative implications called Distress. It is the most commonly-referred to type of stress, whereas eustress is a positive form of stress, usually related to desirable events in person's life. Both can be equally taxing on the body, and are cumulative in nature, depending on a person's way of adapting to a change that has caused it.

Both negative and positive stressors can lead to stress. Some common categories and examples of stressors include: sensory input such as pain, bright ligght, or environmental issues such as a lack of control over environmental circumstances, such as food, housing, health, freedom, or mobility. Social issues can also cause stress, such as struggles with conspecific or difficult individuals and social defeat, or relationship conflict, deception, or break ups, and major events such as baby birth, deaths, marriage, and divorce.

Life experiences such as poverty, unemployment, depression, obsessive compulsive disorder, heavy alcoholic dringking, or insufficient sleep can also cause stress. Students and workers may face stress from exams, project deadlines, and group projects.
Adverse experiences during development (e.g. prenatal exposure to maternal stress, poor attachment histories,sexual abuse are thought to contribute to deficits in the maturity of an individual's stress response systems.

The neurochemistry of the stress response is now believed to be well understood, although much remains to be discovered about how the components of this system interact with one another, in the brain and throughout in the body. In response to a stressor, corticotropin-releasing hormone (CRH) and arginime-vasopressin (AVP) are secreted into the phypophyseal portal system and activate neurons of the paraventricular nuclei (PVN) of the hypothalamus.
The locus ceruleus and other noradrenergic cell groups of the adrnal medulla and pons, collectively known as the LC/NE system, also become active and use brain epinephrine to execute autonomic and neuroendocrine responses, serving as a global alarm system. The autonomic nervous system in the body provides the rapid response to stress commonly known as the fight - -fight response, engaging the sympathetic nervous system and withdrawing the parasympathetic nervous system, thereby enacting cardiovascular, respiratory, gastrointestinal, renal, and endocrine changes. The hypothalamic-pituitary-adrenal axis (HPA), a major part of the neuroendrocrine system involving the interactions of the hypothalamus, the pituitary gland, and the adrenal gland, is also activated by release of CRH and AVP.
This results in release of adrenocorticotropic hormone (ACTH) from the pituitary into the general bloodstream, which results in secretion of cortisol and other glucocorticoids from the adrenal cortex. These corticoids involve the whole body in the organism's response to stress and ultimately contribute to the termination of the response via inhibitory feedback.
Stress can significantly affect many of the body's immune systems, as can an individual's perceptions of, and reactions to, stress. The term psychoneuroimmunology is used to describe the interactions between the mental state, nervous and immune systems, as well as research on the interconnections of these systems.

Chronic stress has also been shown to impair developmental growth in children by lowering the pituitary gland's production of growth hormone, as in children associated with a home environment involving serious marital discord, alcoholism or child abuse.

Hope this information can change the wrong thinking of stress.
Stress itself not always negative.
Well, Manage your stress and be a winner.
