/0 Comments/in /by

What is Seasonal Affective Disorder (SAD)?

SAD is a form of depression typically associated with the winter months. Winter Pattern SAD begins in the fall, extending through the spring. It more often affects women and those who are younger, in life’s middle years. SAD is more common in far northern and southern latitudes, being further from the equator. Thus SAD is a relevant mental health topic for Canadians.

Science continues to study SAD’s causes. A family history of depression is a related factor. Other suspected causes are lowered vitamin D production, altered regulation of serotonin, and overproduction of melatonin, increasing sleepiness. It is unclear if shortened days are a cause although it is suggested, including by those with SAD. There is a less frequent Summer Pattern of SAD with some symptoms that vary from the winter condition.
