Adrenal fatigue is caused by continual over stimulation of the adrenal glands from constant stress. The adrenal glands have difficulty keeping up with the constant demands and become limited in their ability to adapt too many stressors. This manifests as a number of symptoms, one of which is exhaustion that doesn’t resolve with the typical rest and relaxation.
Typically, most people adapt well to the stresses of life. However, as we continually place increased demands on ourselves, our adrenal glands are constantly stimulated to produce stress hormones as our bodies’ way of coping. As the stressors continue and less time is allowed for sleep and rest, ‘adrenal fatigue’ is often the result.
