Brighter Blue-Enhanced Light to Boost Alertness and Performance in Rotating Night Shift Workers

AI simplified

Abstract

A 4.5-fold increase in melanopic illuminance significantly improved alertness and performance in night shift workers.

  • Exposure to higher intensity, blue-enriched lighting led to significant improvements in subjective sleepiness and reaction times during night shifts.
  • KSS scores and mean reaction times on the Psychomotor Vigilance Task were significantly better during the lighting intervention compared to traditional lighting.
  • The number of lapses in reaction time on the PVT also decreased significantly with the blue-enriched lighting condition.
  • No significant differences in self-reported mood were observed between the two lighting conditions.
