Seasonal Affective Disorder (SAD), also known as winter depression, is a form of depression which comes and goes with a particular season, most often winter. SAD is classified under the DSM as a mood disorder. One if its main causes is seasonal variation in natural light which upsets the body’s circadian rhythm.


Some of the symptoms of SAD include:
  1. Persistent feelings of sadness or hopelessness
  2. Anxiety
  3. Moodiness or irritability
  4. Weight gain
  5. Headaches
  6. Sexual problems
  7. Social anxiety
  8. Over-sleeping
  9. Fatigue
  10. A craving for heavy carbohydrates such as pastas.

The Stats

  1. Nearly 500 000 Americans suffer from SAD.
  2. More women suffer from it than men
  3. People between the ages of 15 and 55 are most likely to be affected
  4. People who may have a genetic predisposition for depression are more at risk
  5. Most SAD sufferers live far away from the equator, where the days shorten during winter months and exposure to sunlight is reduced.

Light Therapy

The most common form of therapy for SAD sufferers is light therapy. This includes specialized lightboxes that contain different wavelengths of light rays to simulate sunlight. Another common type of light therapy is a dawn simulator, a special light programmed to gradually increase in intensity during morning hours, simulating the sun setting. Artificial light therapy is good when natural light is unavailable, but according to one particular study, even the winter sun is more powerful. The study found that during the winter months, walking outside for an hour during daylight is equivalent to two and a half hours under bright artificial lights.
