Prof. Graham Pierce, Ph.D.Light box therapy is a direct response to seasonal change in mood through a resetting of the circadian clock. Specialized lamps that simulate daylight are used for this treatment. Treatment helps ease the winter-time blues by regulating biological processes that impact energy and emotional functions.
Circadian Rhythm Regulation
- Morning light exposure synchronizes your body's internal clock
- Aligns sleep-wake cycles with natural daylight patterns
- Reduces daytime fatigue and evening restlessness
Neurochemical Balance
- Suppresses excess melatonin production causing drowsiness
- Stimulates serotonin release improving mood stability
- Enhances dopamine for better focus and motivation
Using the light box properly in the morning is what makes it so effective. When you do light therapy in the morning, do it within 30 minutes of waking up. This coincides with the cortisol peak for most people. Put it at eye level, 18 inches away. For most people, 20 to 30 minutes is enough.
For many people, the treatment is effective without the need for medications. It offers an alternative, natural approach to addressing seasonal mood challenges. Many people report an increase in energy and the ability to balance their emotions. Some people find improvement in symptoms of winter depression.
A primary factor in the success of light therapy is safety; therefore, always choose devices that hold a medical-grade certification and/or safety approval. Do not stare directly into the light to protect your eyes. If you are taking photosensitizing medication or have any eye problems, consult your doctor first.
