What Is Stress?

Researchers define stress as the psychological and physiological condition that a person experiences when a situation is perceived as threatening, harmful or demanding.
Stress is in the mind of the beholder.
While negative events can be stressful, so can positive changes. Getting married, being promoted at work, taking that trip to Europe, and moving to that great new home can all create stress.
The more effective people feel in a given situation, the better they cope. The benefit to thinking you are effective is that you’re more likely to take changes and success in stride—which reinforces your belief that you are effective.
