Study: Bright Light Therapy Can Treat Non-Seasonal Depression

According to the study authors from Brazil and Argentina, major depressive disorder is a leading cause of disability worldwide. However, the response rate to initial depression treatment is less than 50 percent, highlighting the need for alternative or supplementary therapies like bright light therapy.

How Does Bright Light Therapy Improve Depression?

Analysis of clinical trial data revealed that incorporating bright light therapy alongside traditional depression treatment can enhance the response rate to treatment. Those receiving bright light therapy had a 40 percent response rate compared to 23 percent in those without the therapy. This demonstrates that bright light therapy can be a valuable addition to depression treatment and can expedite the response to treatment.

SAD lamps, also known as light boxes, emit intense light similar to natural outdoor light. This exposure can lead to chemical changes in the brain, increasing serotonin levels, improving mood, and reducing fatigue.

For optimal effectiveness, SAD lamps should be used within the first hour of waking up for about 30 minutes and positioned 16 to 24 inches from the face. It’s important to keep the eyes open without directly staring at the light. While these lamps can be purchased without a prescription, consulting with a healthcare provider before starting bright light therapy is recommended.

It’s crucial to emphasize that bright light therapy should complement other depression treatments and not replace them. Therefore, individuals should consult with their healthcare provider before making any changes to their treatment plan.
