Things that trigger a stress response in some people may fail to do so in others. But even when a stress response occurs, the extent to which a person suffers from the stress depends on how well he or she copes with it. Stress causes health and social problems when people fail to handle it properly.
Some people are better than others at coping with their stress.
People with a basically Type A personality delberately keep themselves in a high state of stress. Instead of trying to reduce their stress level, they carry on setting themselves new targets, and giving themselves new tasks to complete.

They use a variety of physical and psychological techniques to relieve tension and calm themselves down. They are able to sleep and unwind even when their problems are mounting up.
