The Positive Side of Stress

As many people have noted, the stress response can be enormously helpful. Surging adrenaline enables people to perform Herculean feats. Fight-or-flight responses are appropriate and essential in such overwhelming situations. When appropriately invoked, the stress response helps us rise to many challenges. These challenges may be external forces, such as a fire or an earthquake, or internal threats, such as your circulatory system teetering on the brink of a deadly collapse. The fight-or-flight response can prove beneficial under far less dangerous circumstances, too.

Physiologist Hans Selye, whose work helped shape modern stress theory, advanced the idea that physical and psychosocial stressors trigger the same physiological response. Selye explored the line between short-term stress that stimulates people to summon the resources to hurdle obstacles (so-called "good" stress) and chronic or overabundant stress, which wears down the ability to adapt and cope ("bad" stress or distress).

Two Harvard researchers, Robert M. Yerkes and John D. Dodson, likewise demonstrated that a jolt of stress isn't necessarily bad. They noted that as stress or anxiety levels rose, so did performance and efficiency — up to a point. At this turning point, further stress and anxiety led to significant decreases in performance and ability.

Where that line is drawn or where that turning point falls seems to differ from person to person. For while the stress response is hard-wired into humans and other animals, the events and perceptions that set it off vary widely. What you perceive as a threatening situation, your neighbor may easily brush aside or even relish.

Who knew stress could be a good thing!?
