Stress
Stress is defined as a mental and physical condition that occurs when an adjustment or adoption must be made into the environment. Unpleasant conditions or events cause stress, as, for example, financial problems, divorce, health issues, or pressure at work. However, a certain amount of stress occurs even when the adjustment is to a condition that is perceived as desirable. Exercise, dating, moving to a new home, or taking a trip are all stressful situation. Although short- term stress is usually harmless, the consequences of long-term stress can be dangerous to health. Factors that decrease the consequences of stress are the ability to predict stressful situations and he level of control over them that can be achieved.
