SAD/Winter Blues

What is Seasonal Affective Disorder (SAD)? A type of depression that occurs during specific seasons, usually fall or winter. SAD is characterized by a seasonal pattern of symptoms that can vary from mild to severe. 

Symptoms include:

• Feeling sad, anxious, or empty

• Loss of interest in activities

• Fatigue and decreased energy

• Difficulty concentrating

• Changes in sleep or appetite

• Unplanned weight changes

• Physical aches or pains

• Thoughts of death or suicide

• Social withdrawal 

 SAD is more common in people who live farther north, where there are fewer daylight hours in the winter. SAD can be caused by a number of factors, including:

• Less sunlight and shorter days

• Melatonin, a sleep-related hormone

• A chemical change in the brain

• Low vitamin D
