Cortisol Balance

Meaning

Cortisol Balance refers to the physiological state where the secretion and metabolic clearance of the glucocorticoid hormone cortisol adhere to a healthy, predictable circadian rhythm and maintain appropriate overall levels. Optimal balance is characterized by a high morning peak to initiate wakefulness and a steady, gradual decline throughout the day, reaching its nadir before sleep. Disruptions to this rhythm, often due to chronic psychological or metabolic stress, can profoundly impact sleep quality, immune function, and the regulation of other key hormones like thyroid and sex steroids. Achieving this balance is fundamental to maintaining HPA axis integrity and systemic health.
