Think about how good you feel outside under a cloudless blue sky. Bring that sense of well-being indoors with NatureBright's Sky Effect light therapyLight therapy or phototherapy consists of exposure to daylight or to specific wavelengths of light using lasers, light-emitting diodes, fluorescent lamps, dichroic lamps or very bright, full-spectrum light -- by a so-called light box. Light therapy which strikes the retina of the eyes is used to treat circadian rhythm disorders such as delayed sleep phase syndrome and can also be used to treat seasonal affective disorder, with some support for its use also with non-seasonal psychiatric disorders. .
Sky Effect technology capitalizes on a revolutionary scientific discovery. It stimulates a special receptor in the human eye. This retinal receptor, found in 2002, is sensitive to light frequenciesElectromagnetic radiation is classified according to the frequency (or wavelength) of the light wave. This includes (in order of increasing frequency): natural electromagnetic waves, radio waves, microwaves, terahertz radiation, infrared (IR) radiation, visible light, ultraviolet (UV) radiation, X-rays and gamma rays.. It responds to different light wavelengthsElectromagnetic radiation is classified according to the frequency (or wavelength) of the light wave. This includes (in order of increasing frequency): natural electromagnetic waves, radio waves, microwaves, terahertz radiation, infrared (IR) radiation, visible light, ultraviolet (UV) radiation, X-rays and gamma rays. Of these, natural electromagnetic waves have the longest wavelengths and gamma rays have the shortest., particularly to blue light. Why is this key? It recalibrates (or sets) our internal body clockA circadian rhythm is a roughly 24-hour cycle in the biochemical, physiological or behavioral processes of living entities, including plants, animals, fungi and cyanobacteria (see bacterial circadian rhythms). based on the information it receives. When our body clock is set correctly, we sleep peacefully, regulate our appetite, and feel happy.
How does this work? The receptor senses blue light and sends signals to the hypothalamus, that area of the brain where sleep, hormonal, and emotive functions are regulated. Extra blue light signals can help us get back on track if we're restless, nervous, or have just travelled across time zones.

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 affects the secretion of the hormone, melatonin. Melatonin helps our bodies know when it is time to sleep and to wake.
New Frontiers in Health
NatureBright collaborated in a study at Duke University to measure how light therapy could alleviate symptoms of chronic fatigue.
