Your Care Instructions

Seasonal affective disorder (SAD) is a type of depression that some people get during the short days of fall and winter. You may feel unhappy and tired during fall and winter. But you feel more cheerful and have more energy in spring and summer. You may gain weight and exercise less in winter. You also may feel more grouchy during winter. You may find it hard to get along with family and co-workers.

Doctors think that having less natural light may cause SAD. Your doctor may recommend light therapy. This helps many people with SAD. With light therapy, you are near artificial bright lights for a set period of time each winter day. Most people do this in the morning. You should feel better soon after you start light therapy. You may need to keep doing it until spring. Your doctor also may prescribe antidepressant medicine and suggest exercise. Both of these can help your mood.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

  • If your doctor recommends light therapy, use it as directed. Your doctor may have you sit or lie down a certain distance from the light. Two common types of light therapy are:
    • Bright light treatment. You sit in front of a "light box" for a certain amount of time. This is most often done in the morning. Be sure to read and follow the directions.
    • Dawn simulation. This is done while you sleep. A low-intensity light turns on at a set time in the morning before you wake up. It slowly gets brighter.
  • Tell your doctor about any conditions you have and medicines you take before you start light therapy.
  • Be safe with medicines. Take your medicines exactly as prescribed. Call your doctor or nurse call line if you think you are having a problem with your medicine.
    • You may need to try several antidepressant medicines before you find the one that works best for you.
    • Don't stop taking antidepressants, even after your symptoms go away. If you continue to take them, it helps prevent depression from coming back.
    • Antidepressants may have side effects, but the side effects go away after a while. Talk to your doctor about any side effects or other concerns.
  • Get at least 2½ hours of exercise a week. Try to exercise first thing in the morning during winter. This may help improve your energy level and relieve depression. Walking is a good choice. You also may want to do other activities, such as running, swimming, cycling, or playing tennis or team sports. In bad weather, you can use an indoor treadmill or walk at a mall.
  • Eat a healthy, balanced diet to relieve some of the symptoms of SAD.
  • Try to spend time outside each day. Natural sunlight, even if hidden by clouds, is always helpful for people with SAD.
  • Ask your doctor about using complementary medicine, such as melatonin. They may help relieve symptoms of SAD. Do not take St. John's wort if you take antidepressants.
  • Do not use illegal drugs, and limit your use of alcohol.
  • Stay active. Try to do the things you usually enjoy, even if you don't feel like doing them.
  • Do not make major life decisions when you are depressed. You will make better decisions after you feel better.
  • If home treatment does not seem to work, consider counselling. A counsellor can help you understand SAD and may help you prevent symptoms.
