The Exhaustion Stage is when, eventually the physiological systems in the previous(prenominal) stages become ineffective and the initial ANS symptoms of stimulation reappear. In extreme cases, attempts to return to a normal soil fail, and the nett stage occurs. The positive evaluation of Selyes exertion is that the work started the endure a line of understanding stress.
