Coping With Winter Depression & Tips for Managing Seasonal Affective Disorder

November 27, 2004 — In the fall and winter months, some people suffer from symptoms of depression that can appear gradually or that come on all at once. These symptoms often dissipate when spring arrives and stay in remission through the summer months. Symptoms of depression that come during the colder months can be associated with Seasonal Affective Disorder (SAD). This mood disorder is often attributed to the lack of light during the colder months of the year.

"SAD is a real mood disorder that requires diagnosis and may require treatment. If you regularly experience a significant, lasting, downturn of mood when the weather gets colder and daylight lessens then you should consider consulting a psychiatrist or other health professional to discuss your symptoms," says Douglas Jacobs, M.D., Executive Director of the nonprofit organization Screening for Mental Health and Associate Clinical Professor of Psychiatry at Harvard Medical School.

SAD has been linked to a biochemical imbalance in the brain brought on by the shortening of daylight hours and a lack of sunlight in winter. The most difficult months for SAD sufferers are January and February. Younger persons and women are thought to be at higher risk. There is also some evidence suggesting that the farther someone lives from the equator, the more likely they are to develop SAD. Whereas the exact number of Americans suffering from SAD is not known, it is believed that between 10 percent and 20 percent of the U.S. population may suffer from mild symptoms associated with the disorder. These symptoms can include:

Excessive sleeping, difficulty staying awake, overeating, and weight gain during the fall or winter months

	Feelings of extreme fatigue, inability to maintain regular lifestyle schedule
	Depression (feelings of sadness, loss of feelings, apathy) combined with irritability
	Lack of interest in social interactions, losing interest in activities of enjoyment
	Remission of symptoms in the spring and summer months

Those suffering from mild cases of SAD can benefit from additional exposure to the sun. This can include a long walk outside or arranging your home or office so that you are exposed to a window during the day. For many suffering from more severe cases of the condition, light therapy (phototherapy) has proven an effective treatment option. This form of therapy involves exposure to very bright light (usually from a special fluorescent lamp) for a few hours each day during the winter months. Additional relief has been found with psychotherapy sessions, and in some cases, prescription of antidepressants.

"Getting screened and evaluated is a smart, sensible way to take care of your health and ensure that you can enjoy the pleasures of the season," says Jacobs. Symptoms of SAD can be confused with other medical conditions, such as hypothyroidism or viral infections like mononucleosis, so a proper evaluation by a medical professional is crucial.
