The circadian rhythm is our internal biological clock : a regulatory system that coordinates sleep, wakefulness, metabolism, body temperature, and hormone production over the course of a 24-hour period.
Cortisol and melatonin are the main hormones that mark this rhythm:
the first promotes energy and concentration during the day,
the second induces relaxation and regenerating sleep during the night hours.
By taking blood samples at 4 times a day , this test allows us to analyse the physiological trend of cortisol and melatonin, highlighting any alterations linked to chronic stress, insomnia, fatigue or metabolic difficulties.
Re-establishing a correct circadian rhythm means:
Improve sleep quality
Optimize cognitive functions
Support metabolism
Strengthen the body’s overall resilience
The test assesses your circadian rhythm by measuring cortisol and melatonin levels at four points throughout the day. It provides a map of your personal biological clock, useful for prevention, personalized anti-aging medicine, and chronic stress management.
