Detrimental Effects of Blue Light from Electronics on Sleep

Dec. 3, 2015; 1-2:30 p.m. (ET)

Light isn’t just for vision. In addition to enabling us to see, light is the major synchronizer of our bodies’ circadian rhythms to the local time on earth. Light can also induce an acute alerting effect on people. Lighting characteristics affecting vision are different than those affecting our biological rhythms and our acute alertness. Different types and levels of light can affect a person's ability to see clearly, identify people and objects, and drive safely.

Certain types of light applied at certain times of the day can increase sleep efficiency of older adults and reduce symptoms of seasonal affective disorder, or SAD, felt by many people during winter months. If applied at the wrong time, light can lead to circadian rhythm disruption, which has been linked to increased risk for diseases and disorders. How and when lighting can be used to promote health and well-being of those suffering from circadian disorders will also be discussed.

At the conclusion of this webinar, participants will be able to:

  • Demonstrate understanding of the circadian rhythm by identifying at least three ways to measure it.
  • Identify lighting characteristics that affect shift worker’s circadian rhythm.
  • Analyze symptomology of sleep and circadian rhythm disruption in military settings.
