Average mid‐sleep time as a proxy for circadian phase
Using Average Mid-Sleep Time to Estimate Internal Body Clock Phase
AI simplified
Abstract
A single sleep-time assessment can represent melatonin phase by over 60%.
- Current methods for assessing circadian phase using melatonin are complex and time-consuming.
- Common sleep-time indices do not reliably reflect melatonin phase.
- The proposed single sleep-time assessment offers a simpler alternative for estimating circadian phase.
- This assessment improves the alignment of subjective sleep reports with objective melatonin phase measurements.
