Researchers at the National Institute of Health demonstrated that white light, in a
range of 2,500 to 10,000 LUX (a measurement of light intensity), helped to reverse the
symptoms of winter blues.
Exposure strategies affect people differently. We all have different reactions to our
environment. It is important to establish a distance and schedule that is comfortable for
you. We recommend you use the light regularly and at about the same time each day.
It is not necessary to sit in front of the lamp continuously. You can divide the time into
several mini-sessions. Continue to use the HappyLight daily to feel an improvement in
your mood and activity level.
When you are feeling sluggish and lethargic, spend more time with the light or sit closer
to it. If you feel a sort of edginess, as though you have consumed too much coffee, it
may be time to turn off the unit.
* Recommended exposure time is a function of output and distance. Individual results
may vary . Also, refer to the warnings below.
