                                                                Secret History Behind The Science Of Stress
In our daily lives, we often encounter phenomena known as general name is Stress. We do not think that all stress is bad, but pathological stress can not do without harm to psychological, physiological and behavioral activities, even in relation to the psychological and physical condition of the child. people. 

History of Stress

Mechanism of disease and clinical manifestations of stress disorder are diverse and complex. The basic issues of stress such as: adaptive response and pathological response of the body to stress factors; Factors supporting stress; Nervous response – body fluids with stress; Clinical manifestations of stress etc. Is being fully researched.
Stress is not only the object of medical research, but also the subject of many other disciplines such as psychology and sociology. Here we approach the problem of stress from the perspective of medical psychology. .
History of Stress Research
The initial term for stress is used in physics, to refer to the compression that a material has to endure. Walter Canon then used this term in physiology to refer to emotional stress. In 1935 he went into deep research on endothelial balance in mammals when they were in a difficult situation, especially when the temperature changed. He also describes the emotional factors involved in the development of certain diseases and defines the role of the body’s nervous system in responding to emergencies.
In medicine, attention is paid to the question of why patients with different diseases have similar symptoms. Many authors have described the symptoms.

Stress research 

Gastric and intestinal ulcers in patients with burns (eg Svon 1823, Kerling 1842); Or in patients after a major infection (eg Brillrot, Germany), the Pasteur Institute and the Yersen Institute described the adrenal glands of the guinea pigs growing and bleeding when infected with diphtheria.
In life, the concept of stress is used to refer to the phenomenon of physical exhaustion or exhaustion after a period of hard labor; After a period of cold or heatstroke, hot drunk, heavy blood loss, severe infection, frightened, straight-faced, anxious or exhilarating pleasure.
Obviously the cause of the phenomena is different, but the body’s response to them is the same. All this reaction takes place in three stages:
– At first, orange people are difficult
– Stage two, people adapt to difficulties
– The third stage, the last stage, human beings can not stand anymore.
The three stages of this reaction are like a general rule of conditioning the behavior of
Every creature under special stress conditions, like an adaptive response
Non-specificity of the body for the different, heavy, sudden effects of the lips
Hormone and give it to mice. After a time injection, the mouse has the following manifestations:
– The adrenal cortex grows sharply and contains large amounts of secreted lipids
– Thymus, lymph nodes and lymphoid structures are shrinking
– Stomach, duodenal ulcer, ulcer and bleeding.
Other experiments have shown that extracts from the adrenal glands, pancreas and some other substances also cause similar variations.
At the beginning, these changes are called “symptoms caused by the effects
Different personality. “Later, they were changed to” general adaptive symptoms, “also known as” biological stress symptoms “. And the three transformations have become the three important indicators of stress and are the basis for discovering a full concept of stress.
The Conclude
In reality, stress is a term that sometimes refers to a cause, a stressor (such as city noise, heat, illness, job displacement, or occupation), or When it comes to the effects of strong stimuli (such as panic during heavy calamities, stress when facing difficulties in work …). Thus, stress indicates both the attacker and the reaction of the body to the agent. Or, like Hans Selye, is the correlation between stimuli and body responses.
– Stress as a response of the subject to a need or a correspondence between the relationship between people and the surrounding environment.
– Stress is a psychological, biological and behavioral adaptation. Stress places the subject in the process of adaptation to the surrounding environment, giving the body a new balance after being exposed to the environment. In other words, normal stress responses contribute to the body’s adaptation.
– If the individual’s response to stress factors is not adequate and inappropriate and the body does not create a new balance, then the body’s functions are more or less disordered, signs of pathological body , Psychology, behavior will appear and will create acute or prolonged pathological conditions.
