seasonal affective disorder
noun
Did you know?
Seasonal affective disorder hasn't been recognized as a medical condition for very long, and the term has only become part of the general English vocabulary during the past three decades or so (its earliest documented appearance in print dates from 1983). "Seasonal affective disorder" (abbreviated SAD) is also sometimes called "Winter Depression" and some researchers describe it as a "hibernation reaction" in which sensitive individuals react to the decreasing amounts of light and the colder temperatures of fall and winter.
