DO YOU HAVE SEASONAL AFFECTIVE DISORDER (SAD)?
What is Seasonal Affective Disorder (SAD)?
Seasonal Affective Disorder is a form of depression that follows a seasonal pattern. Most often, symptoms begin in late fall or early winter and start to lift in spring when daylight increases. Clinically, it’s considered a type of major depression or bipolar disorder with a “seasonal pattern,” rather than a separate illness.
What causes SAD?
SAD is strongly linked to reduced exposure to natural sunlight during shorter fall and winter days. Less light can disrupt the body’s internal clock (circadian rhythm), lower serotonin, and alter melatonin levels. People with a personal or family history of depression or bipolar disorder appear to be at higher risk.
What are the symptoms of SAD?
SAD includes persistent sadness, low mood, loss of interest in activities, tiredness, oversleeping, increased appetite, carbohydrate cravings, weight gain, and difficulty concentrating. Severe cases may involve feelings of worthlessness or thoughts of death or suicide.
What are the most effective treatments? Bright-light therapy is one of the most effective treatments. Counseling, especially cognitive behavioral therapy, can be helpful. Medication may be prescribed in some cases. Healthy routines—daylight exposure, physical activity, regular sleep, and social connection—also monitoring and support for negative moods
