Allostasis is the process of achieving stability, or homeostasis, through physiological or behavioral change. This can be carried out by means of alteration in HPA axis hormones, the autonomic nervous system, cytokines, or a number of other systems, and is generally adaptive in the short term (McEwen & Wingfield 2003).
Homeostasis is the maintenance of a constant environment in response to internal and external stimuli.The body requires the constant and healthy environment that only homeostasis can provide Without this environment the body wouldnât be able to carry out the life support process.omeostasis is the maintenance of a constant environment in response to internal and external stimuli.
