Definition of Stress

In 18-19 centuries the word “stress” was used mainly in Physics to define:

  • the internal distribution of force of pressure within a body;
  • strain or deformation which has arisen in a subject under influence of such force.

In the beginning of 20th century Hans Selye, endocrinologist and biologist, has brought the word “stress” to medicine. He discovered that stress can be caused by both - positive or negative impulse and demonstrated the existence of stress diseases.

What is the definition of stress and how it affects our body?

The stress is the response of the body to perceived or actual changes. In fact, anything that causes a “good” or “bad” change in your life is the reason for stress. When you are going to buy a new car, that is stress. If you were promoted at work, that is stress. Broken hand, hay fever or traffic jam is also stress. Even thoughts about possible changes, e.g. financial worries, cause stress.Actually, stress is a vitally essential reaction of our body, as it helps to adapt to the changes of an environment. There are three basic phases of stress:

Phase 1:

Stressors elevate adrenaline and trigger the stress response in our bodies.

Phase 2:
The second phase includes the reaction and adaptation to a difficult situation. The ability of our body to cope with stress depends on interpretation of stress. If you believe that potential changes can result in threats you decrease your ability to cope with stress. Thus, it is highly important to work on your attitude and reaction to stressors, so you would be able to re-evaluate stressful situations and make them less threatening.

Phase 3:
This phase mainly deals with . When our body is under influence of stressful events it releases two hormones: noradrenalin and adrenaline. Adrenaline, which is also called “a hormone of stress”, has a very important role. When it is released in large quantities into the blood, it has numerous effects throughout the body - increase of heart rate, raise of the blood pressure and increased levels of glucose in the blood. All these changes make the body prepared for the intensive work. However, too much of stress may have negative effect on your body - it can result in diseases of nervous system. Neurosis is considered to be one of the most dangerous, as it causes a number of other serious diseases, such as hypertonic illness, an atherosclerosis, ischemic illness of heart, heart attacks, insults, stomach ulcers, etc.

Therefore, it is highly important to learn how to manage stress and solve the problem as it comes.
