Substance Overview

Listing Status: Topic selected for evaluation

Primary Uses or Exposures

  • People who, by virtue of the nature of their work, lifestyle choices, or residence, are subjected to interruptions in the natural light-dark cycles and have the potential for circadian disruption.
  • Over 10 million adults (7% of the U.S. population) frequently work night shifts (defined as working any amount of time between 1:00 a.m. and 5:00 a.m. for 6 to 30 days over the previous 30-day period).
  • People are exposed to aberrant lighting conditions resulting from exposure to electrical light at night (LAN) from outdoor lights, indoor lights at home and at work, and using self-luminous electronic devices.
