A comfort zone is a psychological state in which things feel familiar to a person and they are at ease and in control of their environment, experiencing low levels of anxiety and stress. In this zone, a steady level of performance is possible.
Bardwick defines the term as "a behavioral state where a person operates in an anxiety-neutral position."Brown describes it as "Where our uncertainty, scarcity and vulnerability are minimized — where we believe we’ll have access to enough love, food, talent, time, admiration. Where we feel we have some control."
Stepping out of a comfort zone raises anxiety and generates a stress response. This results in an enhanced level of concentration and focus.
White (2009) refers to the "optimal performance zone", in which performance can be enhanced by some amount of stress.Yerkes (1907) who reported, "Anxiety improves performance until a certain optimum level of arousal has been reached. Beyond that point, performance deteriorates as higher levels of anxiety are attained." Beyond the optimum performance zone, lies the "danger zone" in which performance declines rapidly under the influence of greater anxiety.
Optimal performance management requires maximizing time in the optimum performance zone.
