Seasonal affective disorder, or SAD, is a psychological condition provoked by a seasonal change that results in depression. While people can experience SAD at any time of year, the majority of cases occur in the winter when daylight is scarce. An accepted theory behind the cause of SAD is that decreased sunlight exposure directly affects a person’s biological clock and disrupts their regulation of hormones, neurochemicals, sleep, and overall mood.
Symptoms of SAD are akin to those of major depression:
- Difficulty concentrating
- Loss of interest in activities once previously enjoyed
- Changes in sleep patterns
- Reduced sex drive
- Changes in appetite and weight gain
