Shrink Definition
The cortisol awakening response is a natural surge of the stress hormone cortisol in the first half hour after waking. Far from harmful, this healthy spike helps mobilize energy and prepare you for the day. Its size shifts with stress, sleep, and health, so a blunted or exaggerated response can signal strain. It's part of the body's normal daily rhythm.
Plain language
A healthy surge of cortisol right after you wake up.
