More than the Winter Blues: Seasonal Affective Disorder

Just as it seems to do each year, fall has rushed past and winter is at our doors. For some this is an exciting time, involving holidays spent with loved ones, warm nights snuggled by the fire and cool, sunny afternoons at the beach. However, for up to eight million Americans who suffer with seasonal affective disorder, this time of year can be very difficult.

SAD is a mood disorder associated with depression and related to seasonal variations of light. Brought on by the shorter days and longer nights, symptoms disappear completely in the spring. They include:

• Sleep Problems – Desire to oversleep, disturbed sleep or difficulty staying awake
• Lethargy – A feeling of fatigue and inability to carry out normal routines
• Overeating – Craving sugary or starchy foods
• Social Problems – Irritability and desire to avoid social situations
• Anxiety – Tension and inability to tolerate stress
• Loss of Libido – Decreased interest in sex or physical contact
• Mood Changes – Extremes in mood and/or short periods of hypomania

These symptoms can significantly disrupt one’s life. Yet those who experience SAD do not have to suffer through the winter. There are many options to help them feel better.

Phototherapy, or bright light therapy, has shown to suppress the brain’s production of melatonin, a chemical linked to SAD. The device most commonly used is called a “light box.” There are also a variety of light bulbs available that offer the same benefit, though their effects are milder and not scientifically proven. Typically, people need to use bright light therapy for about 30 minutes each day throughout the fall and winter.

Increasing exposure to natural light also helps. In fact, a half-hour walk outside equates to two and a half hours of bright light therapy. Opening blinds and curtains to allow more light into your office and home is another way to increase natural light.

If light therapies do not work, people can work with their health care provider to identify other alternatives, such as antidepressant medications and therapy. However, these options can take over a month to show benefits and may come with unwanted side effects.

Regardless of which treatment a person determines to work best, relief is possible. People living with SAD do not need to remain in the dark. SAD is a real and common disorder, though it is one that can be effectively treated.
