Stress hormones such as cortisol, GH and norepinephrine are released at periods of high stress. The hormone regulating system is known as the endocrine system. Cortisol is believed to affect the metabolic system and norepinephrine is believed to play a role in ADHD as well as depression and hypertension.
Stress hormones rise in the body during any neuroendocrine reaction such as surgery and they remain high to as long as 72 hours after which all these hormones return back to their normal level, the last being cortisol.
