SAD is major depression with a seasonal pattern. This means that most feel episodes of depression during the fall or winter months.  (Scientists have seen a striking example in Scandinavia where suicide rate doubles in the winter months.)

Symptoms of SAD may include

• lack of interest in usual activities,
• loss of appetite,
• social withdrawal,
• feelings of guilt, hopelessness, or worthlessness,
• feelings of anxiety,
• poor concentration,
• difficulty falling or staying asleep.

Why does this occur?  In short, this is not fully understood.  Genetics, age and the body’s natural chemical makeup may all play a role.  Our biological clock (circadian rhythm) is disrupted with reduced levels and amounts of sunlight.  Reduced sunlight can cause a decreased level of serotonin (which is a feel-good chemical in the brain).  Melatonin may also decrease–this impacts our ability to get a restful night sleep.

When to see your doctor?  If your symptoms (as listed above) extend beyond a week or two, if you feel hopeless, think about suicide, or use drug/alcohol to help “cope.”

What are treatments?  Light therapy may help the brain chemicals be tricked into thinking it’s spring/summer.  Antidepressant medication may also help.  Counseling is a third way to help.

Don’t brush off that “winter blues” feeling.  Help is available.
