Think about how good you feel outside when there's a cloudless blue sky. That sense of well-being can be brought indoors with PER 3TM Sky Effect light therapy.

Sky Effect capitalizes on a revolutionary scientific discovery of a third receptor in the human eye. This retinal receptor, found in 2002, is sensitive to light frequencies. It doesn't necessarily »see« color or light but it responds to different wavelengths in light, particularly to the length of blue light. What's the most significant about the way the body »reads« light with this receptor is how it can recalibrate our internal time or body clock based on the information it receives. How does it work? The receptor in the eye's retina picks up the blue light and sends signals to the hypothalamus, that area of the brain where sleep, hormonal, and emotive functions are regulated. It stimulates an area of cells that are seen at the physical locus of our body clock, or Circadian rhythm.

The newly discovered receptor: Intrinsically Photosensitive Retinal Ganglion Cells (Responsible for regulating circadian rhythms)                                              
Rods and Cones (Not responsible for regulating circadian  rhythms)              
The more in sync our body clock is with optimal natural cycles, the better it will work to stimulate our overall wellness. We'll sleep well, eat regularly, and experience emotional stability and better spirits. If our clock is out of sync, which can happen from illness, night shift work, jet lag, or winter light deprivation, we can experience disturbing symptoms such as insomnia, and other problems that can range from daytime drowsiness to even depression.
This recently discovered receptor also effects the secretion of the hormone, melatonin. Melatonin helps our bodies know when it is time to sleep and to wake. It helps us match our appetite patterns with times of day.
