Introduction Allostatic load refers to the cumulative effects of chronic and acute stress on the body.  It is the process and the product of ‘wear-and-tear’ on the body and brain.  This results from chronic over-activity or inactivity (called dysregulation) of physiological systems that are normally involved in adaption to environmental challenges (McEwen & Gianaros, 2010).  The frequency of exposure to these challenges is unique to each individual and individuals accumulate allostatic load at different rates over the life-course.  The outcomes of allostatic load can be physiological, psychological, and psychosocial health conditions.
