Treatment for seasonal affective disorder may include light therapy, medications and psychotherapy. If you have bipolar disorder, tell your doctor - this is critical to know when prescribing light therapy or an antidepressant. Both treatments can potentially trigger a manic episode.

Light therapy

In light therapy, also called phototherapy, you sit a few feet from a special light box so that you're exposed to bright light within the first hour of waking up each day. Light therapy mimics natural outdoor light and appears to cause a change in brain chemicals linked to mood. Light therapy is one of the first line treatments for fall-onset SAD. It generally starts working in a few days to a few weeks and causes few side effects. Research on light therapy is limited, but it appears to be effective for most people in relieving SAD symptoms. Before you purchase a light box, talk with your doctor about the best one for you, and familiarize yourself with the variety of features and options so that you buy a high-quality product that's safe and effective. Also ask your doctor about how and when to use the light box.

Medications

Some people with SAD benefit from antidepressant treatment, especially if symptoms are severe. An extended-release version of the antidepressant bupropion (Wellbutrin XL, Aplenzin) may help prevent depressive episodes in people with a history of SAD. Other antidepressants also may commonly be used to treat SAD. Your doctor may recommend starting treatment with an antidepressant before your symptoms typically begin each year. He or she may also recommend that you continue to take the antidepressant beyond the time your symptoms normally go away. Keep in mind that it may take several weeks to notice full benefits from an antidepressant. In addition, you may have to try different medications before you find one that works well for you and has the fewest side effects.

Psychotherapy

Psychotherapy, also called talk therapy, is another option to treat SAD. A type of psychotherapy known as cognitive behavioral therapy can help you :

1. Identify and change negative thoughts and behaviors that may be making you feel worse
2. Learn healthy ways to cope with SAD, especially with reducing avoidance behavior and scheduling activities
3. Learn how to manage stress

Mind-body connection

Examples of mind-body techniques that some people may choose to try to help cope with SAD include :

1. Relaxation techniques such as yoga or tai chi
2. Meditation
3. Guided imagery
4. Music or art therapy

Lifestyle and home remedies

In addition to your treatment plan for seasonal affective disorder :

1. Make your environment sunnier and brighter. Open blinds, trim tree branches that block sunlight or add skylights to your home. Sit closer to bright windows while at home or in the office.
2. Get outside. Take a long walk, eat lunch at a nearby park, or simply sit on a bench and soak up the sun. Even on cold or cloudy days, outdoor light can help — especially if you spend some time outside within two hours of getting up in the morning.
3. Exercise regularly. Exercise and other types of physical activity help relieve stress and anxiety, both of which can increase SAD symptoms. Being more fit can make you feel better about yourself, too, which can lift your mood.
