Talk with your doctor first

It's best to talk with your health care provider about choosing and using a light therapy box. If you're experiencing both SAD and bipolar disorder, the advisability and timing of using a light box should be carefully reviewed with your doctor. Increasing exposure too fast or using the light box for too long each time may induce manic symptoms if you have bipolar disorder.

If you have past or current eye problems such as glaucoma, cataracts or eye damage from diabetes, get advice from your eye doctor before starting light therapy.
