Coping strategies such as denial are used and the fight or feather response is less effective. When the stress reduces there is a head of adjustment.

The Exhaustion Stage is when, eventually the physiological systems in the former stages become ineffective and the initial ANS symptoms of stimulation reappear. In extreme cases, attempts to return to a normal soil fail, and the lowest stage occurs. The positive evaluation of Selyes exe rtion is that the work started the determin! e of understanding stress. It has been useful in predicting physiological responses to stress. The GAS provides a very useful model of the course of visible injuries and disorder in cases where stress is prolonged. The negative evaluation of the... If you wish to micturate a full essay, order it on our website: BestEssayCheap.com
