Resistance: organism makes efforts to cope with the threat, as though confrontation and trying to achieve homeostasis: 3. Exhaustion: organism fails to overcome the threat and depletes its physiological resources in the process of trying. It provides a way of thinking about the interplay of physiological and environmental factors; it posits a physiological mechanism for the stress-illness relationship: prolonged or repeated stress has been implicated in a broad array of disorders. Tend-and-befriend: animals do(cid:374)"t (cid:373)e(cid:396)el(cid:455) fight, flee, a(cid:374)d g(cid:396)o(cid:449) e(cid:454)hausted i(cid:374) (cid:396)espo(cid:374)se to st(cid:396)ess. It is more associated with more confident expectations of the ability to cope with the stressful event, more favourable emotional reactions to the event, and lower bp.
