Quizplus · Accepted Answer

Light therapy is often used to treat seasonal affective disorder (SAD) by resetting circadian rhythms. Exposure to bright light helps to suppress the release of melatonin, which helps to regulate sleep, and stimulates the release of serotonin, which improves mood. However, it does not increase melatonin levels. Light therapy is generally considered a safe and effective treatment, although there may be some side effects, such as headaches or eyestrain. It does not lead to abnormal production of hormones and neurotransmitters.
