What is the Biology of Sleep?
Melatonin levels testing enables sleep medicine providers to index an individual’s circadian rhythm (biological clock) thorough sampling protocols, such as Dim Light Melatonin Onset (DLMO). Circadian Phase Assessments can be performed at-home or in-clinic to evaluate circadian rhythm alignment, phase duration, and melatonin secretion patterns (enabling the screening for hypermelatoninemia or hypomelatoninemia). Assessments also facilitate the evaluation of pharmaceutical interventions or sleep supplements in order to appropriate targeted timing of treatments or medication dosages. While many sleep disorders are not circadian in nature, routine sleep disruptions, therapeutics, and habitual behaviors can modulate the circadian rhythm over time. Screening patients early provides an opportunity to identify areas of concern that may need to be addressed while providing treatment for both circadian and non-circadian based sleep disturbances.
