Although judicious exposure to sunlight - when available - can act like light therapy, this method would not be practical for most people with contemporary lifestyles and careers. The key is to reset the internal biological clock, which begins to run late as the sunrise gets later and later in the fall and winter.
Therefore researchers use light boxes to simulate the effects of daylight. By sitting in front of a light box for about 20-30 minutes, the brain is tricked into thinking you are in the brighter part of the day. Optimum light therapy usually works best the first thing in the morning, shortly after awakening.
The Day-Light was designed to include features which provide optimal light therapy treatment and for the user:
Height Adjustable Legs - The height adjustable legs allow the light to be positioned at the appropriate height and angle for the user. This is the optimal light positioning as recommended by light therapy experts.
Glare-Free - The white diffusing lens eliminates glare and evenly distributes the light. Three 36-watt light tubes emit a warm light and minimize potentially harmful blue rays.
UV Filtered & Safe - Hi-impact polycarbonate lens filters 99.3% of harmful UV rays.
Flicker-Free - Manufactured with high efficiency, electronic ballasts, the Day-Light eliminates the annoying flicker experienced with ordinary fluorescent fixtures.
Two Light Settings - The three-light setting provides 10,000 lux at 12". The two-light setting option is convenient for ambient lighting.
Built-in Stand - There is a built-in stand located in the back of the unit which can be pulled out to set the Day-Light up for the ambient lighting option.
Built-in Handle - There is a built-in handle located in the back of the unit for easy transport.
