If you’ve ever stared out the window at 4:30 p.m. (when it’s already pitch black) wrapped in three blankets, wondering if you should move to Costa Rica immediately… you’re not alone. What you might be feeling isn’t just the winter blahs – it could be Seasonal Affective Disorder (SAD). And yes, SAD is a very appropriate acronym, because it can make everything feel heavier than that oversized parka you’re wearing.

Recognizing Symptoms of SAD

SAD symptoms can look like:

  • Feeling down or hopeless for weeks at a time

  • Sleeping too much but still waking up exhausted

  • Craving carbs like your life depends on it

  • Trouble concentrating or feeling motivated
  • More irritable
  • Pulling away from people and social activities

What is SAD vs Depression?

Here’s the quick breakdown:

  • SAD is a type of depression that shows up with the seasons, usually in late fall or winter when sunlight is scarce.
  • Depression can happen any time of year and isn’t tied to the amount of daylight.

SAD tends to follow a predictable pattern – you feel better in spring and summer when the sun comes back to visit.

Think of it this way, depression is like an uninvited house guest who won’t leave, while SAD is like a moody relative who only drops by in the winter. If you notice that symptoms occur every winter and lift in the spring, it’s worth paying attention and considering meeting with a depression therapist in Toronto to discuss any questions or concerns you may have.

Causes of SAD

Research suggests that Seasonal Affective Disorder as well as Major Depressive Disorder (MDD) tends to increase with latitude and be triggered by changes in the amount of sunlight we receive (CAMH).

Changes in light may:

  • Confuse a person’s biological clock or circadian rhythm, which controls sleep-wake patterns
  • Disturb neurotransmitter functions like serotonin and dopamine.

Women are more likely than men to be diagnosed with SAD, and the disorder tends to emerge in young adulthood, although people of all ages can be affected.

Why SAD has a Particular Bite in Toronto

It is estimated that 15-20% of Canadians experience a form of SAD during the winter months. A significant cause of this is that geographically, Canada, and hence Toronto, is at a higher latitude, leading to longer and darker winters (PMC).

Here’s a snapshot of how living in Toronto can take a greater toll on one’s mental well being during these colder months:

  • Less sunlight: The sun in winter sits lower in the sky, and cloud cover is common, so the effective ‘bright sunlight’ exposure we get is substantially less. 
  • Long duration: Toronto Winters can extend for 4–5 months, meaning extended exposure to low light.
  • Shorter days: Earlier sunsets and later sunrises often means spending larger parts of the active day indoors (commuting before sunrise, heading home after sunset) which reduces natural daylight exposure. 
  • Urban winter safety: Concerns for falling due to icy roads and freezing winds can reduce physical activity and social connection.
  • Work culture: Expectations for productivity and normal work routines remain even with bad weather and darkened days. 
  • Physical environment: Grey concrete, tall buildings, and grey skies create visual monotony that can impact motivation and mood.

Self Help & Practical Tools for Seasonal Affective Disorder

You don’t have to wait for spring to feel better. Try these lifestyle adjustments this winter in Toronto:

1. Soak up as much daylight as you can:

Even a short walk during midday can help reset your body’s internal clock.

  • Schedule a 20–30 minute walk between 11 a.m. and 2 p.m. when sunlight is strongest.

  • Best Toronto spots:
    • The Toronto Music Garden or Harbourfront trail on sunny winter days

    • High Park for forest light and fresh air

    • The Don Valley Trail for peaceful nature exposure, even in colder months

    • If commuting downtown, step outside at lunch to catch daylight near Nathan Phillips Square or Queen’s Park

2. Increase light sources

Because Toronto’s winter daylight can drop below 9 hours, a light therapy lamp can help mimic the effects of natural sunlight.

  • Use a 10,000-lux lamp for 20–30 minutes each morning, ideally before 9 a.m.

  • Position it at eye level, about 16–24 inches away while you read or have coffee.

Look for models certified by Health Canada, such as Verilux or Northern Light Technologies (a Canadian brand).

3. Keep your body moving

Cold and snow can make exercise less appealing, but movement is crucial for balancing serotonin and energy levels.

  • Indoor options: Yoga or spin classes at YMCA Toronto, Sweat & Tonic, or GoodLife locations across the city. Even stretching while binge-watching Netflix at home, can help boost endorphins.

  • Outdoor options: Bundle up and get outside – ice skate at Nathan Phillips Square, walk the Beltline Trail, or hike Evergreen Brick Works trails on bright winter mornings.

4. Rework your winter environment

Make your living and work spaces brighter and cozier to lift mood:

  • Open blinds fully and sit near windows when possible.

  • Add mirrors to reflect natural light into rooms.

  • Choose warm-toned lamps and avoid sitting in dim light for long stretches.

  • Consider replacing overhead fluorescents with full-spectrum daylight bulbs.
  • Incorporate flowers or plants to add vitality indoors.

5. Routine resets and Vitamin D

  • Keep regular sleep and wake times, even if your bed is extra cozy.
  • Maintain a balanced diet by prepping for snacks and meals for the week ahead.
  • 5,000 IU of vitamin D per day can help replace your body with any deficiency in darker months (nimh)

6. Prioritize connection and joy

Isolation tends to increase during Toronto winters. Build “light moments” into your weekly rhythm:

  • Host or attend cozy gatherings – a board game night, book club, or dinner with friends.

  • Explore Toronto’s indoor attractions when it’s too cold outdoors: the AGO, ROM, or St. Lawrence Market offer bright, lively spaces.
  • Keep small rituals that anchor joy – listening to energizing music on your commute, journaling, or lighting candles in the evening.
  • Schedule contact with family and friends with walks or outings to local coffee shops.  

How Therapy Helps Manage Seasonal Shifts

Sometimes SAD needs more than light lamps and long walks. If low mood persists for more than 2 weeks, therapy and medication can help. Our Horizon Therapy counsellors provide a personalized approach  that focuses on one or more therapy modalities to help you manage SAD symptoms better during the winter months.

Medication

For some people, antidepressant medications such as selective serotonin reuptake inhibitors (SSRIs) like bupropion may be needed to help manage SAD. SSRIs help to increase serotonin levels in the brain, reducing symptoms of depression. Your physician may suggest beginning medication before the winter, especially if you have a history of recurring SAD episodes.

Cognitive Behavioural Therapy (CBT) 

Talking it through with a therapist helps you recognize any thought patterns that pull you down and keep you stuck, create realistic coping strategies for low-energy days, explore deeper feelings that surface during quieter, darker moments, and remind you that what you’re experiencing isn’t laziness – it’s biology. CBT Toronto therapists also uses behavioural activation techniques and teaches coping strategies for managing seasonal stressors and reducing social withdrawal during the winter months. Therapy is a space to be understood, supported, and gently nudged back toward the light, even when the outside world feels dim.

Mindfulness Therapy

Mindfulness and mind body therapies can support you with SAD by helping you stay present and compassionate with yourself. Mindfulness reduces rumination and self-criticism – two patterns that often worsen low mood. Through gentle practices like breath awareness, noticing sensations, or mindful walking, you can reconnect with your body, calm the stress response, and build emotional resilience. Instead of fighting the season, mindfulness encourages acceptance and self-care, helping you respond to shifts in mood with understanding rather than frustration. Over time, this awareness helps to strengthen balance, lightness, and stability. 

Studies suggest that when combined with other treatments such as light therapy and medication, talk therapy can provide long-term relief from SAD symptoms.
