DLMO: The Gold Standard Test for Measuring Your Circadian Clock Timing
What Is the Most Accurate Way to Measure Your Individual Circadian Timing?
Dim Light Melatonin Onset (DLMO) is the gold standard test for measuring individual circadian timing, providing the most reliable indicator of when your biological clock naturally wants to initiate sleep. DLMO measures the precise time when melatonin levels begin to rise in dim light conditions (typically less than 10 lux), revealing your personal circadian phase independent of external factors like bright lights or sleep schedules. This measurement is crucial for diagnosing circadian rhythm disorders and optimizing personalized sleep timing recommendations.
