Using Wearable Devices to Track Sleep and Body Clocks in Intensive Care Nurses: A Review

Circadian Biology Weekly Brief ↗PubMed ↗DOI ↗

Updated Sep 5, 2026

Abstract

Wearables may enhance the assessment of sleep and circadian rhythms in critical illness.

Sleep and circadian disruption frequently occur in critically ill patients.
Current bedside assessment methods for sleep and circadian rhythms are challenging.
Wearable devices offer the potential for continuous observation over 24 hours.
The performance of wearables in measuring sleep and circadian rhythms in critical illness needs further evaluation.
