Description: CAR is a transient, immediate rise in cortisol upon awakening and is distinct from the diurnal rhythm. CAR reflects a person's ability to cope with anticipated challenges and their perception of control around chronic stress, providing insight into HPA axis resiliency.

The isolated evening cortisol has distinct clinical implications. Elevated evening cortisol is linked to insomnia and associated with various diseases such as diabetes, cardiovascular disease, hormonally driven cancers, and osteoporosis.
