Sept. 12, 2014
- Being female. SAD is diagnosed more often in women than in men, but men may have more-severe symptoms.
- Age. Young people have a higher risk of winter SAD, and winter SAD is less likely to occur in older adults.
- Family history. People with SAD may be more likely to have blood relatives with SAD or another form of depression.
- Having clinical depression or bipolar disorder. Symptoms of depression may worsen seasonally if you have one of these conditions.
- Living far from the equator. SAD appears to be more common among people who live far north or south of the equator. This may be due to decreased sunlight during the winter and longer days during the summer months.
