Light and health

The human body uses light cues, such as those provided by the sun, to time certain functions. Light exposure can boost mood and energy. Light has direct alerting and energizing effects and can improve our performance. Bright light therapy is also successfully used for mood relief, especially for seasonal mood swings.

In countries with long winters, many people experience loss of energy and low spirits due to lack of light.These symptoms are referred to as the winter blues.They typically start in the fall and may last for several weeks. Exposure to bright light sources can help alleviate these symptoms and restore the summer mood and summer energy level.

The blue light of the summer sky is well known. We do not get as much of this light in the fall and winter, and indoor light does not emit enough of this essential color. The goLITE BLU energy light helps to deliver the  wavelength, color and intensity of light that we see in summer.
