Cortisol irregularity, what to do?

Slight cortisol irregularity is not considered dangerous and may be corrected with a ‘few tweaks’ to diet and exercise and/or improvements to sleep habits. It can also be a catalyst for making the changes one desires. Severe cortisol irregularity is associated with the hypothalamic-pituitary-adrenal (HPA) also referred to as the “stress axis”¹, and should be followed up with a GP.

Work related stress as a factor

Cortisol activates our metabolic break-down processes, known as the ‘metabolism’, making energy-rich compounds available to the body.

cortisol hormone structure

Research in 2018 found that people who were identified as having a high level of work-related stress had noticeably higher cortisol values at midday and in the evening. The study* compared the cortisol levels of burnout patients with those of healthy employees, and considered work related stress.

How stress leads to fatigue

Excessive demand for cortisol triggered by stress negatively impacts the hypothalamic-pituitary-adrenal (HPA), also referred to as the “stress axis”¹. Over time this will exhaust the adrenal glands and disrupt production of other hormones.
