Stress Hormones Defined
A number of different biomarkers have been used in studies of chronic stress and stress-hormone balance. To help you better understand some of the concepts and vocabulary used to explain the biochemical activities that stress sets into motion, here are brief descriptions of these biomarkers:

* Cortisol is a hormone produced by the adrenal glands. Its main “acute” functions are to increase blood-sugar levels (via insulin antagonism), reduce inflammation, and stimulate immune function. Its main “chronic” effects are to increase blood-sugar levels (via appetite stimulation), increase inflammation, and suppress immune function.

* Testosterone and DHEA (dehydroepiandrosterone) are hormones produced by the adrenal glands. They suppress inflammatory cytokines, reduce oxidative damage, and improve insulin sensitivity—but testosterone and DHEA levels are suppressed when cortisol production is elevated, so you “lose” much of their anti-inflammatory and antioxidant benefits during periods of chronic stress.

* Epinephrine, norepinephrine, and dopamine are catecholamines produced in the brain. They increase during acute stress and are involved in brain function and vigilance, but production is suppressed during chronic stress, leading to fatigue, depression, and low vigor.

* Interleukin-6 and TNF-alpha are inflammatory cytokines produced by immune system cells. They normally are produced to slow acute tissue damage, but when produced chronically, they actually lead to accelerated tissue damage.

* C-reactive protein (CRP) is a protein synthesized in the liver. It is elevated during chronic inflammation.
