Range of Light Effects on Human Body Clocks in Light-Adapted People

Circadian Biology Weekly Brief ↗PubMed ↗

Updated

Abstract

A narrow blue circadian sensitivity curve for light-adapted humans has been identified.

  • Light exposure at night can disrupt the timing of cellular processes.
  • Circadian disruption is associated with a wide range of health disorders.
  • Previous research focused on short monochromatic light exposures in dark-adapted conditions.
  • The current review highlights evidence from experiments using spectral filtering of light sources.
  • Findings aid in developing lighting that minimizes circadian disruption during nighttime and optimizes it during daytime.
