Seasonal Depression: Understanding the Winter Blues and Finding Light Again

As the days grow shorter and the temperature drops, many people notice their mood sinking along with the sun. What some dismiss as “winter blues” can actually be a form of seasonal depression, a condition that affects millions each year. Understanding what it is—and learning how to cope—can make the darker months more manageable and even meaningful.

Seasonal Affective Disorder (SAD), commonly known as seasonal depression, is a type of major depressive disorder that follows a seasonal pattern—typically emerging in late fall or winter and lifting in spring or summer. The reduced exposure to natural sunlight disrupts the body’s internal clock, serotonin levels, and melatonin balance, all of which influence mood, sleep, and energy.

Symptoms of seasonal depression may include:

• Feeling listless, sad or down most of the day, nearly every day
• Losing interest in activities you once enjoyed
• Having low energy and feeling sluggish
• Having problems with sleeping too much
• Experiencing carbohydrate cravings, overeating and weight gain
• Having difficulty concentrating
• Feeling hopeless, worthless or guilty
• Having thoughts of not wanting to live

While seasonal depression is challenging, there are proven ways to reduce its impact:

1. Physical activity boosts endorphins and combats sluggishness. Indoor workouts, yoga, or winter walks can all help
2. Even brief exposure to natural light—especially in the morning—can stabilize mood and improve sleep
3. Schedule virtual or in-person meetups to stay connected and avoid isolation
4. Mental health apps like Headspace, Calm, and Moodfit provide guided meditations and mood tracking
5. Therapists can offer counselling using evidence-based modalities such as cognitive-behavioural therapy (CBT) 
6. You may choose to discuss medication with your family doctor or psychiatrist
