For most people (except in the examples below), light therapy has no negative side effects. But it’s always best to talk with your doctor before starting a light therapy routine. If you feel like you’ve had too much caffeine or have trouble falling asleep, then you’ll want to cut back on the amount of time you use your HappyLight® and/or increase your distance from the light.
Mood Disorders - If you have a mood-related disorder, it is essential that you work with your mental health provider to decide if light therapy is the right course of action for you. Light therapy is not recommended for people with bipolar disorder unless under the strict care of a professional.
Eye Conditions - If you have a pre-existing eye condition, you should talk to your doctor before starting a light therapy routine. Some conditions, such as macular degeneration or retinitis pigmentosa may be made worse by exposure to bright light. When discussing this with your provider, make sure he or she is aware that Verilux products contain no UV light as this is a common misconception.
