The Mayo Clinic defines light therapy as "a way to treat seasonal affective disorder, depression and certain other conditions by exposure to bright artificial light. During light therapy, you sit or work near a device called a light therapy box or lamp. The light therapy device gives off bright light that mimics natural outdoor light.
Exposure to bright light from a light therapy box or lamp is thought to alter your circadian rhythms and suppress your body's natural release of melatonin. Together, these cause biochemical changes in your brain that help reduce or control symptoms of seasonal affective disorder and other conditions. Light therapy is also known as bright light therapy or phototherapy."
Light therapy is most effective when used for approximately 30 minutes a day, preferably in the morning.
