Burnout and the Adrenal Glands

I have talked about burnout and the myth that it is caused by “adrenal fatigue.”

I saw some research (NR620) at the 2007 Annual Meeting of the American Psychiatric Association in San Diego, California last month that further nails the idea.

The investigators were from Ege University in Izmir, Turkey, and they looked at 37 people with burnout and did a battery of psychological and endocrine investigations.

The burnout group had:

  • Higher levels of emotional exhaustion and depersonalization
  • Higher depression and anxiety scores on the Beck depression and Beck anxiety inventories
  • Higher scores on the global symptom index


The people with burnout did not have any differences in cortisol levels either at rest or after the investigators did a standard test to stimulate the adrenal glands. They reported exhaustion, but it was NOT caused by a problem with their adrenal glands.

I know that there are still plenty of people promoting the idea of adrenal fatigue, and there are many who sell their services online. The evidence that we have so far indicates that the adrenal glands of most people with burnout seem to be just fine.
