Chronic stress can have a serious impact on our physical as well as psychological health due to sustained high levels of the chemicals released in the ‘fight or flight’ response.
In abused children has been noticed a dysregulation of the "Hypothalamic - Pituitary - Adrenal" axis and particularly anomalous levels of Cortisol (Hart, et al., 1995).
Cicchetti and Rogosch hypothesize that the reduced activity of the HPA axis may have an adaptive role cause it protects against the consequences of a chronic hypercortisolism (Cicchetti, et al., 2010).
They also suggest this alteration to have effects on social skills?
Are there any research about it?
