Seasonal Affective Disorder

Seasonal Affective Disorder, or SAD, is a type of depression that happens during certain times of the year, most often in the fall and winter months. People with SAD may feel sad or hopeless, lose interest in things they used to enjoy, and feel tired or have low energy. They might have trouble sleeping, crave carbohydrates like sweets or bread, and gain weight. Some people with SAD feel irritable, have difficulty concentrating, or feel very sluggish, almost like they are moving in slow motion.

 

SAD is often linked to changes in the seasons, especially the reduced amount of sunlight in the fall and winter. Sunlight helps regulate chemicals in the brain that affect mood, like serotonin and melatonin. When there is less sunlight, serotonin levels may drop, and melatonin levels may rise, which can cause feelings of depression or disrupt sleep patterns. Some people may be more sensitive to these changes than others, making them more likely to develop SAD. Other factors, such as family history or living in areas with long winters and limited sunlight, can increase the risk.

 

Treatment for SAD often includes light therapy, where a special light box is used to mimic natural sunlight. This helps improve mood and energy levels. Cognitive Behavioral Therapy (CBT) is another effective treatment. CBT focuses on identifying and changing negative thought patterns and behaviors that might make depression worse. A therapist might work with a person to recognize thoughts like "I'll always feel this way in winter" and replace them with more helpful thoughts, like "I can take steps to feel better even in the winter."

 

CBT also includes behavioral techniques that help people feel more active and engaged. A therapist might encourage someone to plan enjoyable activities, go outside during daylight hours, or exercise regularly, which can boost mood and energy. For some people, medication like antidepressants may also be helpful, especially when symptoms are severe or other treatments aren’t enough. A combination of therapy, light exposure, and healthy lifestyle habits often works best to manage SAD. 

 

With the right support and treatment, many people with SAD can feel better and enjoy the seasons again.
