Low cortisol levels can increase the risk of wellness issues, including fatigue, weakness, sleep regulation, and dehydration (Lieberman et al., 2005; Liu & Reddy, 2022). Low cortisol levels can sometimes lead to severe co-morbidities, such as Addison’s disease. (National Institute of Diabetes and Digestive and Kidney Diseases, 2017).
