“These findings highlight the potential for lighting interventions to help:

  • Enhance worker performance
  • Bolster overall safety
  • Mitigate health risks

…particularly in workplace settings with chronic dim lighting such as those found across healthcare, manufacturing, and defense industries.”

“The circadian-informed lighting interventions significantly accelerated participants’ adjustment to night work, which could have important implications for improving the health and performance of those who regularly work night shifts.”
