Many people experience a type of depression known as seasonal affective disorder (SAD). SAD is more common in fall and winter, when there is less natural sunlight. The exact cause of SAD is unknown, but it is thought to be related to a disruption of the body’s natural sleep cycle. Symptoms of SAD include fatigue, trouble sleeping, and changes in appetite. SAD can be treated with light therapy, medication, and psychotherapy.
