Keep Your Nighttime Cortisol Optimal

Cortisol, a steroid hormone produced in the adrenal gland, plays a critical role in the stress response, metabolism, immune function, and maintaining daily physiological rhythms.

Normally, cortisol levels peak in the morning and decline throughout the day. However, persistently high levels can lead to health issues such as high blood pressure, muscle degradation, and micronutrient depletion, while persistently low levels can result in fatigue and hypotension.

Various health conditions and medications can impact cortisol levels. Plasma cortisol measurement is the preferred method for assessing adrenal activity, with deviations in its diurnal pattern potentially indicating adrenal dysfunction. Elevated nighttime cortisol may be associated with Cushing's or chronic stress.

Additionally, studies suggest links between cortisol levels and conditions like obesity, polycystic ovary syndrome, and subclinical hypothyroidism.
