What is seasonal affective disorder?

  • Seasonal affective disorder (SAD) is a kind of depression that occurs at a certain time of the year, usually in the winter.

  • Every year, as the days get shorter and the weather gets colder, it is estimated that about 2 or 3 out or every 100 people are affected by SAD. About 15 out of every 100 people have less severe symptoms of SAD called the "winter blues.

  • It is more common in women than in men and it usually begins when people are in their 20s. Older people are at lower risk. Children can also experience SAD, although it is far less common.


  • SAD may begin during the teen years or in adulthood. Like other forms of depression, it occurs more often in women than in men.

  • People who live in places with long winter nights are at greater risk for SAD. A less common form of the disorder involves depression during the summer months.
