Blue light has been found to have a positive effect on individuals suffering from depression, making it the most beneficial LED color for those affected by this condition. Studies conducted have shown the effectiveness of blue light at certain frequencies and wavelengths, even at a lower intensity than full-spectrum light.
Blue light at the wavelength of 480 nm has been found to enhance the mood and emotion of depressed individuals.
It is also suggested that blue light therapy can stabilize and regulate the body’s circadian rhythm, thereby improving overall sleep quality which is often disrupted in individuals with depression.
In addition, exposure to blue light in the morning can help to regulate and boost daytime alertness, and it can improve cognitive function, memory and reduce fatigue.
However, while blue light has shown benefits in treating depression, it is important to note that other factors such as age, gender, medication, and medical conditions can also influence reactions to light therapy. Therefore, it is important to consult with a qualified healthcare professional before starting any form of LED therapy.
