Seasonal Affective Disorder (SAD) accounts for an estimated 10% of all reported cases of depression. Around 2-3% of Canadians will report a serious case of SAD in their lifetime. Canadians are particularly at risk, as we have decreased sunlight during the winter months. Symptoms include irritability and sensitivity in personal relationships, as well as low energy levels and lethargy. It’s very common for people experiencing SAD to oversleep during the winter months. The most widely recommended therapy for SAD is Cognitive Behavioural Therapy (CBT), and psychologists often suggest lifestyle changes like more physical activity and spending more time outside (even when it’s really cold!)
