MyBody-X angle on Cortisol Alltag

Cortisol is a key stress hormone regulating circadian rhythm, metabolism, and immunity. MyBody-X may offer blood tests for cortisol, which can indicate chronic stress or disrupted daily patterns. However, single cortisol measurements are of limited value due to high variability (peak in the morning, trough at night) and influence from sleep, diet, and psychological stress. DNA tests for genes like NR3C1 or FKBP5 provide mechanistic insights, but evidence for actionable everyday recommendations is weak. A more reliable approach involves multiple measurements (e.g., salivary cortisol day curve) combined with lifestyle optimization (sleep hygiene, stress reduction). MyBody-X can serve as a complementary tool but should not replace clinical evaluation for suspected adrenal fatigue or Cushing's syndrome.
