Due to short days and cold weather, you may experience feelings of sadness, loss of energy, and other depressive symptoms this time of year. Reactions to the winter months vary from person to person, with some getting “winter blues” and some experiencing full-on seasonal affective disorder (SAD).

What is seasonal affective disorder (SAD)?

Seasonal affective disorder (SAD) is a type of recurring major depression with a seasonal pattern. This seasonal depression occurs mostly during the beginning of the fall season into winter. SAD affects about 1% to 2% of the population in the U.S., particularly women and young adults, while a milder form of winter blues may affect as many as 10 to 20 percent of people.

What are the symptoms?

For winter-pattern SAD, specific symptoms may include:

  • Oversleeping
  • Overeating, particularly with a craving for carbohydrates
  • Weight gain
  • Tiredness or low energy
  • Social withdrawal (feeling like “hibernating”)

How to prevent SAD?

There’s no known way to prevent the development of SAD. However, you can take steps to manage it or prevent it from coming back.

  • Use your lightbox
  • Exposure to sunlight
  • Eat a well-balanced diet
  • Get regular exercise
  • Stay away from alcohol and drugs
  • Spend time with friends and family
  • Take a tropical vacation
  • Consider seeing a mental health professional

If you think you may be suffering from SAD, talk to your healthcare provider or a mental health specialist about your concerns. If you or someone you know is in immediate distress or is thinking about hurting themselves, text or call 9-8-8 to reach the National Suicide Prevention Lifeline, or visit
