Seasonal Affective Disorder
Seasonal affective disorder (SAD) is a type of depression experienced in relation to the seasons, with symptoms typically beginning in the fall and remaining the same until the onset of spring or summer. Sufferers of SAD may experience feelings of depression, fatigue, sleep disturbances, cravings for carbohydrates, difficulty concentrating and social withdrawal. Symptoms are believed to be triggered by a lack of sunlight, resulting in a disruption of the body's circadian rhythm, leading to biochemical changes in the brain. Treatments for SAD commonly include light therapy, and may also consist of medications, psychotherapy and lifestyle changes. Managing SAD is important for individuals to maintain a normal, healthy quality of life.
