Minimum Recommended Usage
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”.
Different exposure strategies work for different people. 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, sit closer to the light or add more lighting devices to increase the intensity. If you feel a sort of edginess, as though you have drank too much coffee, then it may be time to turn the unit off.
*2,500 LUX at 6". Recommended exposure time is a function of output and distance. Individual results may vary.
