Disclaimer: Neither my comments or experience are a substitute for medical advice. However, I have worked alongside psychiatrists in Toronto-area Emergency Departments for over a decade and support many clients who struggle with Seasonal Affective Disorder.
Against the backdrop of World Mental Health Day on October 10, 2022 and the $1 trillion cost of mental illness to workplaces, seasonal depression is highly relevant topic for Canadians.
Seasonal depression, or Seasonal Affective Disorder (SAD), is a cluster of symptoms experienced typically during fall, winter, and early months of spring when there is a less daylight available. It is a condition influenced by environment and genetics that affects physical and mental state. Common psychological changes include slowed processing speed and decreased mental clarity, and physical symptoms like lethargy, overeating/craving sugar, and decreased physical stamina.
Professionals tell our team they adjust to these unwanted changes with increased caffeine intake and exercise in order to maintain functioning and productivity during this off-season.
But SAD can be improved within 2 weeks by incorporating a cost-fee treatment: sunlight.
Exposure to daylight can lift mood, it’s accessible, and achievable anytime. A SAD light or other light therapies can also be used to mimic the sun and provide a similar effect. Evidence also suggests that SAD could be prevented altogether with the proper strategies in place.
Additional considerations for readers include pediatric onset, heavy genetic loading for disease (family history), comorbidity with substance abuse and Bipolar Affective Disorders, and sleep.
Final thoughts: While the experience of SAD can be a temporary imprisonment for many high-functioning professional people given decreased productivity, quality work product, and resulting frustration that accompanies it, help is available through a family doctor, a psychiatrist, or other healthcare professional who can assist with symptom relief and practical tools to optimize daily functioning both during and after formal office hours.

In summary, clients can re-gain control over SAD by incorporating:
