Winter depression, or Seasonal Affective Disorder, is a form of depression that afflicts a large part of the population during the fall and winter months when sunlight is in short supply. Tending to affect people who live in locales with long winters nights, the most explicit effect SAD has on the body is severe mental and physical fatigue.

An oppressive sluggishness and general inability to feel stimulated is a symptom that directly leads to the onset of other negative effects.
