Stress

What is Stress ?
Technically, stress involves an individual's physical and emotional reaction to pressure from his environment or from within himself. A job promotion is stressful because, although generally positive, it may make one feel that harder work is expected. Thus while stress is often thought to be negative, it may actually help in achieving goals as well as avoiding unpleasant situations. Stress is an avoidable part of life and causes one to be constantly agitated. When this happens, it is possible to become overloaded and suffer physically or emotionally or both.
Some of the stress-related illnesses include:

peptic ulcers
migraine headaches,
depression
ulcerative colitis
high blood pressure
stroke and heart attacks

This doesn’t mean that stress is the direct or principal cause of these illnesses; rather, researchers believe that some people may inherit a biological predisposition to developing a particular disease And on-going stress in such a person’s life may increase the chances that that illness will develop. Illness itself is a source of stress. In addition, continuous stress can weaken the body’s immune system, and as a result the system may become less effective in battling infections. And some authorities suggest that chronic and excessive stress may contribute to the development and progression of cancer.
