December 2025

December is Seasonal Affective Disorder Month –a time to raise awareness about SAD, understanding the signs and symptoms, and to encourage folks to seek help. Seasonal affective disorder is a type of depression that is linked to seasonal changes, especially during the fall and winter months when there are shorter days and less sunlight. SAD is often thought of as the “winter blues” but it is more than that. The “winter blues” is a feeling of sadness during the winter months because of the shortening of days. SAD is a type of depression that follows a seasonal pattern, most commonly during the winter months, but can be experienced during the spring and summer. 

Some Symptoms of the “Winter Blues” include:

  • Low energy
  • General sadness 
  • Increased desire to sleep
  • Reduced motivation

These symptoms are usually mild and temporary and typically resolve on their own.

Some Symptoms of SAD include:

  • Persistent sadness
  • Anxiety
  • Low energy and oversleeping 
  • Insomnia 
  • Poor appetite and weight gain
  • Social withdrawal and loss of interest in activities
  • Violent or aggressive behavior 

These symptoms are more recurring and serious, can be debilitating, and may require treatment.

Some ways to treat SAD include:

  • Light therapy - Treatment where an individual is exposed to a bright light every day for 30-45 minutes to make up for the lack of natural sunlight during the darker months 
  • Psychotherapy - Therapy or counseling that can help individuals with SAD by teaching them new ways of thinking, behaving, and changing habits that contribute to depression
  • Antidepressants - Medications, when prescribed appropriately, can help with symptoms 

Engaging in outdoor activities, exercising, and eating a healthy diet can also help with SAD.
