Bright light therapy and body clock control for preventing delirium in hospitalized adults

Circadian Biology Weekly Brief ↗PubMed ↗DOI ↗OA ↗

Updated Sep 29, 2026

Abstract

Bright light therapy (BLT) may influence circadian regulation and delirium incidence in hospitalized adults.

BLT is associated with potential improvements in circadian rhythms.
Delirium incidence could be reduced with the application of BLT.
The effects of BLT on hospitalized adults warrant further investigation.
