Operation — continued
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, sit closer
to it or increase the light intensity by switching to the high-energy lens. If you feel a sort
of edginess, as though you have consumed too much coffee, it may be time to turn off
the unit or reduce the intensity of the light.
* Recommended exposure time is a function of output and distance. Individual results
may vary. Also, refer to the warnings at the bottom of page 6 of this manual.
WARNING:
Some people may experience light sensitivity to fluorescent
lighting. Discontinue use if you experience any discomfort. Follow directions
for pretest on page 6 prior to use.
WARNING:
Certain drugs may induce light sensitivity (e.g., anti-
depressants) which may result in discomfort or a level of hyperactivity. Consult
with your health care provider before using this product.
WARNING:
If you have a pre-existing eye condition, contact your
health care provider prior to use.
