Seasonal Affective Disorder
Seasonal affective disorder (SAD)
is a type of depression that happens during a change of seasons. SAD usually happens during autumn and winter months when there is less sunlight because the days are shorter. This is called winter-onset depression. Symptoms usually go away in late spring or early summer. Episodes of SAD may be mild or severe.
Call 911 if:
- You have thoughts of harming or killing yourself.
Contact your healthcare provider if:
- You have new or worsening symptoms, even after treatment.
- You have questions or concerns about your condition or care.
Other signs or symptoms you may have with SAD:
- A change in appetite, or a craving for carbohydrates
- Weight gain or loss without trying
- Less energy than usual, or oversleeping often
- Trouble concentrating or sleeping
- Feeling anxious, irritable, or hopeless
- Headaches or other pain
- Loss of interest in activities you usually enjoy, or not wanting to spend time with others
Your healthcare provider may recommend a combination of the following:
- Antidepressants may be given to help improve your mood.
- Therapy is used to help you talk about any negative feelings or depression you are feeling. You may also be able to learn how to prevent or manage SAD by talking about what worked in past years.
- Light therapy may include sitting in front of a light box or wearing a light visor for a certain amount of time each day. A light timer in your bedroom can turn lights up slowly. This may help you wake up more naturally than when you use an alarm clock. Do not use a tanning bed instead of a light box or visor. Tanning beds can cause serious skin damage.
Prevent or manage SAD:
- Exercise as directed. Exercise can help improve depression and make you feel less anxious.
- Eat a variety of healthy foods. Healthy foods include fruits, vegetables, lean meats, fish, whole-grain foods, and low-fat dairy products. Limit sugar and foods that contain simple carbohydrates, such as cookies and cake.
- Create a sleep routine. Go to bed at the same time each night, and get up at the same time each day.
- Increase your exposure to light. Turn on lamps in your home. Go outside several times during the day. Even on cloudy days, you will be in helpful sunlight. If possible, visit areas that get more light than where you live.
- Manage stress. Stress can increase depression and make it harder to sleep.
- Do not drink alcohol or use illegal drugs. Alcohol and drugs can make depression worse. Ask your healthcare provider for more information if you need help quitting.
