Seasonal affective disorder (SAD) is a form of depression that follows a seasonal pattern, typically worsening during fall and winter months when daylight hours decrease. While SAD is more commonly associated with northern climates, Miami and South Florida residents can also experience seasonal mood changes — sometimes in a reverse pattern with symptoms worsening during the intense heat and isolation of summer months.
SAD shares core symptoms with major depressive disorder: persistent low mood, loss of interest in activities, fatigue, difficulty concentrating, feelings of hopelessness, and changes in sleep and appetite. Winter-pattern SAD often involves oversleeping, carbohydrate cravings, and weight gain. Summer-pattern SAD may present with insomnia, decreased appetite, weight loss, anxiety, and agitation.
Treatment for SAD may include light therapy (for winter-pattern SAD), medication such as SSRIs or bupropion, psychotherapy (particularly CBT adapted for SAD), vitamin D supplementation, and lifestyle adjustments including regular exercise and structured social engagement. Your psychiatrist can help determine the right combination based on your specific pattern and severity.
If you notice your mood consistently dipping during certain seasons, a psychiatric evaluation can determine if SAD is the cause and create a proactive treatment plan. Learn when to see a psychiatrist.
