Seasonal Affective Disorder
Medically reviewed by Drugs.com. Last updated on Mar 5, 2023.
Seasonal affective disorder (SAD) is a type of depression that happens during a change of seasons. SAD usually happens during autumn and winter months when there is less sunlight because the days are shorter. This is called winter-onset depression. Symptoms usually go away in late spring or early summer. Episodes of SAD may be mild or severe.
