What is sleep light therapy?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
If you have trouble sleeping, consider sleep light therapy, which is based on maintaining your body's natural circadian rhythm. Natural sunlight contains all the colors of the rainbow, including blue light, which helps us stay alert during the day. But if you're around anything that emits blue light at night, such as TVs, computers or lamps, you can be kept awake. On the other hand, orange, the only color that contains no blue light, can help stimulate the production of melatonin, the sleep hormone.

  • Turn on orange light bulbs in your bedroom 90 minutes before bed. Purchase online for $5.
  • Invest in an orange monitor cover for your computer. Available online for about $40.
  • To wake yourself up in the morning, try a blue-light emitting box. Place it near your breakfast table or at your desk for 15 minutes. Purchase online for about $50.
