Cortisol hits our brain when we wake, it circulates in our blood on the daily, and it comes to our aid every time we exert ourselves, like during a workout for example.
The problem lies in the chronic dysregulation of the nervous system that has come to characterize modern life for hundreds of millions of people.
When we are in a chronically sympathetic nervous system dominant state, cortisol production is ramped up to levels that are beyond our normal energy needs.
