According to the Canadian Mental Health Association, about 15 per cent of Canadians experience a wave of low emotions during the upcoming cold and dark days, or as we know it, the winter blues. Some experience a condition called Seasonal Affective Disorder, known as SAD. It can actually impair daily life and lead to medical treatment. Dr. JianLi Wang, the Director of the Work and Mental Health Research Unit at the Royal's Institute of Mental Health Research in Ottawa, explains the ways we can assess ourselves, make sure we are okay and how fight back those pandemic winter blues.
