Light impacts variations in mood, alertness and sleepiness, affecting performance, comfort and well-being.  Lighting is essential to support visual performance; however, exposure to natural light in particular has been shown to reduce the impact of environmental stressors and is supportive to overall well-being.


  • Being in a room with windows is best.
  • If possible, open the blinds and utilize any opportunities to incorporate natural lighting into the surrounding environment.
  • Adjust interior lighting if possible to a comfortable level of brightness.
