When done correctly, light therapy has been shown to relieve seasonal affective disorder (SAD). When a person with SAD is exposed to bright fluorescent light using the proper intensity, duration, and time of exposure, says the National Alliance on Mental Illness (NAMI), she will likely experience relief from winter depression. Spending more time outdoors on sunny days, when possible, can also help to alleviate SAD.

On the Other: Some Side Effects May Occur

Some side effects such as headaches, eye strain, or nauseau may occur in rare cases as a person begins light therapy, says the National Alliance on Mental Illness (NAMI). Side effects usually cease quickly, allowing the person to continue light therapy (NAMI). Some patients may need additional therapy to overcome their seasonal depression, and they should consult with a psychologist about how to address their SAD.

Bottom Line

Light therapy is one of the most natural types of therapy, and it can quickly show results for someone with SAD. Morning light exposure is particularly effective, especially when a person begins waking up earlier to reset her Circadian rhythm, says NAMI.
