Do you tend to start feeling unhappy around the same time each year? If so, you might have seasonal affective disorder (SAD), a type of depression that the American Psychiatric Association estimates affects about 5% of U.S. adults. Below, we explore what causes SAD and describe the symptoms that it often produces.
What Causes SAD?
Researchers are still working to determine exactly what causes seasonal affective disorder. However, studies suggest that SAD may be connected to circadian rhythms, melatonin levels, and serotonin levels, all of which can be affected by the changing seasons.
What Are the Symptoms of SAD?
As its name suggests, seasonal affective disorder is related to the change in seasons, beginning and ending around the same time each year. Most people with this condition tend to feel depressed in fall and winter, but some grow depressed in spring and summer. When SAD occurs, it can make someone:
- Feel agitated, anxious, guilty, hopeless, irritable, listless, sad, sluggish, tired, or worthless
- Lose interest in their favorite activities
- Find it difficult to focus
- Sleep more or less than usual
- Lose their appetite or overeat (particularly carbohydrates), leading to weight loss or gain
In some especially severe cases, individuals with SAD may experience suicidal thoughts.
