Cortisol

Unit: μg/dL

What is Cortisol?

Morning cortisol is the stress-rhythm hormone that helps you wake up and feel alert. It naturally peaks in the morning and eases off through the day: like a built-in alarm clock. A healthy morning rhythm supports your energy, your sleep and how well you handle stress.

What moves this value?

Sleep deprivation, prolonged busyness, shift work and the exact time of measurement can influence the morning value.

Regular sleep times, daylight in the morning and genuine moments of rest support a healthy rhythm. Discuss a strongly unusual value with your doctor.

The colour zones are personal: they depend on age, sex, risk and history, and appear in the patient's own report.

Insights to discuss with the patient, not a diagnostic instrument.
