Information on Light Therapy for Seasonal Affective Disorder (SAD)

Seasonal Affective Disorder, (SAD) or Winter Depression, is defined as a Major Depressive Disorder with a Seasonal pattern. Almost everyone is affected to some extent by changes in the seasons. Light therapy is often recommended as a first line intervention for this condition because experience, and most clinical studies, have found that it is more effective than antidepressant medications. Light therapy, which for most people involves less than 1/2 hour of exposure to the light therapy lamp, is essentially a natural intervention. It has the same effect on a person as traveling towards the equator where the days are longer, and does not have the pharmacological side effects associated with mood influencing drugs.

SAD is a form of depression that occurs in individuals who are particularly sensitive to seasonal changes. For these people, the effect of short days in winter causes severe winter blues that interferes with their ability to function normally. Seasonal Affective Disorder is linked to the activity of the internal body clock, a neural center in the brain of all mammals that regulates seasonal changes in eating, sleeping, and social activity. In winter the body clock senses the shortening length of day and responds by causing mammals to sleep longer and eat more, in order to conserve energy and gain weight to survive harsh winter conditions. Humans often experience these changes as a reduction in energy levels and a tendency to gain weight in the winter months. More on The effect of the seasons on human physiology..

While it was originally believed that exposure to bright light is needed to influence brain physiology and reset the body clock, numerous independent studies in laboratories around the world have found that Sunnex Biotechnologies low-intensity Lo-LIGHT therapy technology influences the body clock as effectively as bright light, but in a safer and more comfortable manner.

Lo-LIGHT therapy lamps do not use high intensity light, The GreenLIGHT technology is a selected narrow spectrum of green light wavelengths to which the body clock is particularly sensitive. The hazard that exposure to blue light wavelengths from bright light and blue light therapy lamps is now becoming more widely recognized, and concerns about the contribution to age related blindnes from exposure to blue light has now been expressed by several retinal sprecialists. The combination of low intensity and the elimination of blue light makes Lo-LIGHT lamps less hazardous than normal indoor lighting, adn cabn be used without risk of eye damage even by people with pre-existing ocular damage. Lo-LIGHT therapy lamps have been used for over 15 years to safely and comfortably help customers feel happier and more energetic through the winter months.
