Abstract

AbstractAssessments of circadian phase using melatonin are laborious. Sleep‐time indices allow for less laborious phase calculations, but common indices weakly represent melatonin phase. We show how a single sleep‐time assessment can represent melatonin phase by over 60%, improving the use of subjective sleep to mirror objective circadian phase.
