Light Therapy Lamps

Feeling the effects of Seattle's gloomy winters? The University of Washington Health Sciences Library currently has three Lumie Vitamin L lamps, also known as happy lamps, available for in-library use. Research demonstrates that bright lamps can provide benefits to wellness by reducing stress and fatigue and improving focus, alertness, and more. Visit the HSL information desk by the upper floor entrance to check out a lamp, and find additional campus resources on the HSL Health and Wellness guide.


  • Sit with the lamp at approximately arm’s length so the light is shining towards your face.
  • You do not need to stare directly at the lamp, but the light must reach your eyes to have an effect.
  • It can be used while using a computer, reading, etc.
  • Dark glasses, tinted lenses, or closing your eyes limit the effects of the light therapy.
  • Using the lamp within three hours of bedtime may make it difficult to fall asleep.
  • Do not use the lamp if you have photosensitivity or recently had eye surgery.
