Stress is not just a nervous strain. Many people identify biological stress with nervous overload or strong emotional stress, and this is primarily the reaction of the body to the appearance of threatening or unpleasant factors in the life situation. Stress is not always harmful. “Any normal activity — a game of chess or a passionate explanation — can cause significant stress without causing any harm,” writes Hans Selye in his book Stress Without Distress. Distress is called harmful or unpleasant stress. Stressful activities can be enjoyable or unpleasant. Distress is always unpleasant.
