What is seasonal affective disorder?

Seasonal affective disorder, more commonly known as seasonal depression, is a type of depression that effects people only during certain seasons — typically fall and winter.

The shorter days and lack of sunlight during winter months can trigger a chemical change in the brain leading to symptoms of depression.

The most common symptom of SAD include: increased sleep, anxiety, daytime drowsiness, fatigue, trouble thinking clearly or concentrating, feelings of hopelessness, social withdrawal and increased appetite.

How to combat winter exhaustion

At times, winter exhaustion can feel crippling, but there are ways to combat it.

• Practice light therapy. Sitting in front of a therapy light for just 30 minutes a day can help diminish winter depressive symptoms.
• Go outside. Spending time outdoors during the winter, even in short doses, can help keep your circadian rhythm is check, improve your mood and help you get a daily dose of vitamin D.
• Take vitamin D supplements or eat foods that are rich with vitamin D, such as egg yolks and salmon.
• Talk with a therapist. If your symptoms feel out of your control, consider speaking with a professional who can provide you with personalized guidance.
