Different exposure strategies work for different people. We all have different

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.
