“You're not losing your spark. You're running on less light.”
It's 4:52 on a Tuesday and it's already dark outside your window. You've been meaning to answer a text since lunch. The dinner plans you were excited about in September now feel like something to get through. You'd quite like to be in bed by eight, and you're not totally sure why.
If the last few weeks have felt heavier than they should, you're not imagining it. And on Sunday, November 1, the clocks go back and the sun starts setting before 5pm. For a lot of people in Toronto, that's the week something quietly shifts.
So let's talk about it. What seasonal depression actually is, how to tell it apart from the ordinary winter blues, and what genuinely helps, including the part nobody mentions: how hard we tend to be on ourselves for slowing down.
You're in very good company
The first thing to know is how common this is. According to Dr. Robert Levitan, a depression researcher at CAMH, somewhere between a third and half of Canadians notice they have less energy and a lower mood as the days get darker, and around five per cent experience it as real depression (CBC News).
That's not a character flaw. It's biology. Your body uses light, especially morning light, to set its internal clock. When there's less of it, the systems that govern sleep, energy and mood can drift out of sync. You feel it as heaviness, fog, or a strange urge to hibernate.
In other words, some of what you're feeling isn't in your head at all. It's in your body, responding exactly the way a body does when the light changes.
Winter blues or seasonal depression?
Most of us get some version of the winter blues. You're a bit slower, you want more sleep and more soup, and you'd rather stay in. But you still enjoy the things you love once you're there, and life mostly keeps working.
Seasonal depression, known clinically as seasonal affective disorder (SAD), goes further. It's depression that follows a seasonal pattern: it tends to arrive in the fall or early winter, lift in the spring, and come back around the same time the following year. Signs to look out for:
Sleeping more than usual and still waking up exhausted
Craving carbs and sugar in a way that feels different from normal
Cancelling plans and pulling away from people you actually like
Things you usually enjoy feeling like effort, or feeling like nothing
A low, flat or teary mood most days, sometimes with irritability you can't explain
Struggling to concentrate or get started on anything
Realizing this happened last winter too, and maybe the one before
If several of these sound familiar and they've been there most days for a couple of weeks, it's worth talking to your doctor or a therapist. You don't need to wait until it's unbearable. And if you ever have thoughts of not wanting to be here, please reach out right away by calling or texting 9-8-8.
Why winter can hit harder than you expect
Here's the part I notice most in my work. The low mood itself is hard enough. What makes it heavier is the story we tell ourselves about it.
Why can't I just get it together? Everyone else seems fine. I'm being lazy.
If you're someone who holds yourself to a high standard, or who's used to being the reliable one for everybody else, slowing down can feel like failing. So you push. You keep the same pace you had in July, on a fraction of the light, and then criticize yourself for being tired.
The timing doesn't help either. Just as your energy dips, the holiday season arrives with more invitations, more expectations and more pressure to be cheerful about all of it. If saying no already feels hard, December can feel relentless. (If that's you, this post on people-pleasing might be worth a read before the invitations start.)
It helps to remember that almost nothing in nature runs at full speed all year. Trees aren't failing in winter. They're conserving. You're allowed to work with the season instead of against it.
What actually helps with seasonal depression
None of these are a cure-all, and the right mix is different for everyone. But they're the things that tend to make a real difference.
Get daylight into your eyes early. Morning light is the strongest signal your internal clock gets. Even on a grey Toronto morning, it's far brighter outside than under your kitchen lights. A 15-minute walk before 10am, without sunglasses, is one of the simplest things you can do.
Ask about a light therapy lamp. Bright-light therapy, usually with a 10,000 lux lamp used in the morning, is one of the best-supported treatments for seasonal depression. An ordinary lamp won't do the same job. Check with your doctor before starting, especially if you have bipolar disorder, an eye condition, or take medication that makes you sensitive to light.
Keep your sleep steady. It's tempting to sleep in on weekends to catch up, but a consistent wake-up time does more for your mood than a long lie-in. Your body likes predictability, especially when the light is unpredictable.
Move, gently, and outside if you can. You don't need a new fitness plan. A walk around the block, a stretch by a window, a few minutes of fresh air at lunch. Movement and daylight together work better than either alone.
Plan connection before you need it. When your mood dips, reaching out gets harder, so set it up now. A standing Sunday walk with a friend. A weekly phone call. Something on the calendar that doesn't depend on you feeling up to it in the moment.
Make a winter version of your routine. Lower the bar on purpose. Fewer evening plans, earlier nights, simpler dinners. It isn't giving up. It's planning for the season you're actually in.
Catch the inner critic. When you notice yourself thinking I'm so lazy, try swapping in something truer: I'm tired, and it's dark at 5pm. It sounds small. Over a whole winter, it adds up.
How therapy can help in the darker months
Talk therapy is one of the most effective supports for seasonal depression, and a form of CBT adapted specifically for winter depression has good research behind it. In sessions, we can build a realistic plan for the season, notice the thought patterns that pull your mood down further, and untangle the self-criticism that so often rides along.
For some people, winter also brings up other things: grief that gets louder around the holidays, loneliness, or strain in a relationship when you're both cooped up indoors. Those deserve attention too.
If getting outside is part of what you need, Walk & Talk therapy might be a good fit. We meet in High Park or along the waterfront, so you get daylight, movement and therapy in the same hour. I also see clients for individual therapy in person in Toronto and virtually, and you're welcome to book a consultation to see whether working together feels right.
The darkest day of the year is December 21. After that, the light starts coming back, a minute or two at a time. You don't have to feel like yourself again before then. You don't have to feel like yourself again all winter.
You just have to be a little kinder to the version of you who's getting through it. Nothing living stays the same shape all year. Neither do you.
