The system developed by NASAThe Verilux® TwiLight™ Blue Light Therapy System brings the same natural, drug-free therapy NASA developed to regulate sleep patterns and increase individual energy levels and productivity. The 460nm blue spectrum light signals the body to stop the production of melatonin, depending on where you are in your sleep cycle. Melatonin, a natural human hormone, synchronizes and regulates the body's circadian rhythms and can have beneficial effects for addressing certian types of insomnia. Use the Twilight for up to 30 mintues per day to help align your body's clock for more energized days and restful nights. There should be no blue light in the environment after using the TwiLight™ at night for 30 minutes, 2 hours before bedtime. That means no TV, no computer, no compact fluorescents - only yellow incandescent bulbs or candles.
- Turn on the TwiLight™ Blue Light Therapy System for 30 minutes and the blue light will help retard the production of pineal melatonin.
- For older people, this allows them to be more alert into the evening hours, and experience a more restful sleep when the body does produce melatonin later in the sleep cycle.
- Teens and young adults find themselves better able to function at school and work after they have used the TwiLight™ right after rising in the morning, as it turns off the production of melatonin.
- This is not a bedside reading lamp, rather a therapy lamp to assist your body in regulating its 24 hour sleep cycle.

The TwiLight™ can be used at the "Waking" point and the "Sleep Switch" point.

Special note: Researchers have found limited evidence that bright and blue light therapy may cause additional harm to people with pre-existing eye damage (including glaucoma and macular degeneration), and could increase the incidence of age related blindness. Medical professionals recommend people with pre-existing retinal conditions be tested prior to using any bright or blue light therapy system.
"I did not think anything could help me sleep at night. Two weeks after using it, I am now sleeping through the night and feeling more productive during the day."

My challenged son loves his Twilight lamp. He goes to bed and turns it on and normally by the time I come upstairs, he is sound asleep and I have to shut it off for him. But he swears it helps him fall asleep.

I am a first year student in Veterinary School and found myself having more and more difficulty falling asleep and staying asleep. This lack of a good night’s rest was affecting my ability to learn and to study. I understand the science behind light therapy and observed how it was used in animals to reset their circadian rhythms during seasonal breeding, so thought I would try it myself. The results were remarkable. I use the Twilight daily and now sleep well and feel rested to begin the day. I am such a believer; I purchased another Twilight for a fellow Vet student.
