If you've ever felt dragged down by the weather, or if the dark days of winter cause your usually sunny disposition to go gloomy, you may have experienced Seasonal Affective Disorder, appropriately referred to as SAD. This condition is also known as the winter blahs and The Alaska Effect, a term that relates to that northern state's long, sunless days of winter. The feelings associated with SAD are very similar to those associated with depression. Most people experience some symptoms of depression at some point in their lives, but SAD is a specific form of depression which is generally symptom free for most of the year. Many SAD patients experience extreme depression during the winter months, though some may show symptoms during the summer or other seasons.
Studies suggest that the lower amount of light in the fall and winter months is a possible causative agent of Seasonal Affective Disorder. This is probably not the only cause. The exact causes of seasonal affective disorder (SAD) are unknown. Chemical changes in the brain caused by changes in the amount of sunlight are probably involved. People who live in geographical locations that are dark or cloudy during the winter are most likely to have SAD. Also, there is a tendency for SAD to run in some families. If you think you may be experiencing some unusual sadness or a recent downturn in mood, you may be feeling the effects of SAD.
Seasonal Depression Symptoms
Seasonal affective disorder (SAD) may have some of the same symptoms as other types of depression. Most people have only some of these symptoms, not all.
Depressed mood
Loss of interest in usually enjoyable activities
Fatigue or loss of energy
Feelings of worthlessness or hopelessness
Poor concentration, indecisiveness
Recurrent thoughts of death or suicide
Fortunately, there is treatment. Simply getting outside and exposing yourself to daylight for 30-45 minutes a day may be enough. And for those of us who work long hours in offices and are unable to get outside during the daylight hours, there are a number of alternate therapies.
Bright-light therapy: This is exposure to bright artificial light, brighter than usual home or office lighting. Bright-light therapy relieves symptoms for about two thirds of people with seasonal affective disorder. Bright-light therapy products are available for sale and range in cost from $200-500. They range from 2,500-10,000 lux. Many experts recommend that 10,000 lux be used. Only devices that filter out harmful ultraviolet waves should be used. Types of devices include light panels or boxes, blankets, and visors. The bright-light source should be placed at eye level. Although staring at the light source is not recommended, the light must enter the eyes if it is to work. (Simple skin exposure does not work.)
Remember that any symptoms of sadness, irritability, or fatigue could be related to seasonal changes in available light, or they could be related to a more serious and long term mood disorder. If you are concerned about your or a friend’s condition, or if you have any questions regarding the symptoms or treatment of SAD or other mood problems, please call to set up an appointment at the Wellness Center. And remember that regular exercise, a healthy diet and routine activity in the out of doors is good policy for anyone, anytime of year.
