During this time of year, some experience Seasonal Affective Disorder (SAD). Sean Miller is the Executive Director of the Canadian Mental Health Association for the Central Region and explains SAD can occur for many reasons. He notes, there are physical, social, psychological, and environmental factors that can cause SAD to occur. He stresses, SAD or seasonal depression is not like a regular low many do experience, but is a persistent and consistent low felt for more than two weeks. Miller believes that during the holidays SAD is much more apparent as it is contrasted with the joy of the holiday season. Miller describes some signs that you or someone you may know may be experiencing SAD: loss of interest, a decrease in energy, feelings of guilt or worthlessness, suicidal thoughts, change in eating habits. He stresses if these symptoms are experienced, reach out for help through your doctor, a trained professional, or self-help groups. In addition to reaching out for professional help, Miller suggests doing some physical activity, eating foods which are proven to boost your mood, and staying away from alcohol as it's a depressant.
