A recent study highlights the potential of bright light therapy as an effective treatment for depression, particularly for individuals suffering from major depressive disorder. Russian psychologist Daria Yaushiva emphasized the significant impact that different lighting colors have on mood and mental health. According to a report from the newspaper “Izvestia,” she stated, “Yellow lighting reduces stress levels, while blue stimulates the brain.”
Yaushiva explained that lighting directly influences both physiological and psychological processes. Too bright lighting causes headaches and eye strain, which heighten anxiety and stress levels. On the other hand, too low lighting brings out lethargy and somnolence, impairs concentration, and negatively affects mood. She pointed out that warm yellow light creates a feeling of comfort and relaxation, while cool ones, like white and blue enhance concentration and alertness.
The Role of Blue Light in Depression Treatment
Blue light, in particular, has been noted to have anti-depressive properties. It is commonly used to treat seasonal affective disorder, a type of depression that occurs during those seasons of the year when daylight is at its shortest. Yaushiva, however warned that sleeping problems can be acquired from prolonged exposure to blue light. For this reason, she said, dim red-orange artificial light should be used at night to stimulate the release of melatonin, the sleep hormone.
It is equally important, according to the specialist, to adjust the light according to the season. In autumn and winter, the sun shines rather scarce, which is why one needs to work with bright white or blue light to struggle against drowsiness and to maintain a good mood. Katerina Gelfand, “Smart Home” division director at Sber, also opined that “Lighting can be adjusted in order to improve mood during these months.“.
Bright Light Therapy: A Non-Pharmacological Solution
Bright light therapy is gaining recognition as a non-pharmacological solution for treating depressive disorders. A recent study indicated that patients with non-seasonal depression who underwent bright light therapy reported a 40% remission rate. This therapy involves sitting in front of a light box emitting bright white light at 10,000 lux for at least 30 minutes daily.
Researchers found that bright light exposure can significantly influence mood regulation by affecting neurons in the retina that transmit visual information to brain areas responsible for mood regulation, such as the amygdala and suprachiasmatic nucleus. The findings suggest that bright light therapy could serve as an effective adjunctive treatment for non-seasonal depressive disorders.
How to Use Bright Light Therapy Effectively
To maximize the benefits of bright light therapy, individuals should use a properly designed light box that emits 10,000 lux. The recommended approach is to sit near the device for about 30 minutes each morning shortly after waking up. It’s essential not to look directly at the light but to keep your eyes open while engaging in other activities like reading or working.
While bright light therapy offers promising results for many people with depression, it’s crucial for individuals with bipolar disorder or severe depression to consult a mental health professional before starting treatment. In rare cases, it may trigger manic episodes or other adverse effects.
