Every year, the third Monday in January is known as Blue Monday — supposedly the “most depressing day of the year,” and for 2026, that falls on Monday, January 19.

The idea traces back to a 2005 marketing campaign by a UK travel company that tried to pinpoint a day when weather conditions, debt levels, time since Christmas and New Year’s resolutions, low motivation and other factors combine to make people feel particularly down. The formula behind it is widely criticised and not scientifically validated, so Blue Monday as the single saddest day of the year isn’t backed by research. But feeling the darkness this time of year most definitely is.

In Canada, the impact of cold, dark days, post-holiday bills and the winter blues are very real phenomena for many people. In fact, seasonal affective disorder (SAD), a periodic form of depression that is believed to be related to the lack of sunlight, affects thousands of Canadians each year. Roughly 15% of the population report experiencing at least some symptoms consistent with seasonal affective disorder during winter — such as low energy, mood changes and increased sleep — and about 2 to 3% experience more serious forms of SAD (1).

While a single Monday in January cannot be labeled as the saddest day of the year with any empirical evidence, winter’s combination of reduced daylight, longer nights and extra financial pressures can create a perfect storm of emotional and financial stress.

Why winter hits some of us harder

Long northern winters can shift your body clock and mood. SAD is a recognized pattern of depression that starts in late fall and lasts until spring. It’s linked to a decrease in sunlight that can affect the brain’s serotonin levels, which play a role in regulating mood.

The so-called winter blues are a milder but widespread reaction to shorter days and harsher weather. Experts say this can feel like persistent low energy, lack of motivation and a slump in mood — the kinds of feelings people associate with mid-January’s Blue Monday.

If you’re also feeling the pinch of heightened holiday spending, rising costs of living and lingering debt, those emotional dips can feel deeper. Financial stress doesn’t just strain budgets, it has a measurable impact on health and wellbeing.

Money worries are hitting Canadians hard

The latest Financial Stress Index from FP Canada and Leger showed 42% of Canadians say money is their top source of stress, more than health, relationships or work (2).

Nearly half of Canadians say they’ve lost sleep because of financial worries according to the Government of Canada's financial wellness survey (3). In fact, financial stress doubles the likelihood of reporting poor health and quadruples the risk of sleep problems, headaches and other physical issues.

Those aren’t just abstract stats — they describe the everyday reality for many Canadians juggling bills, groceries, rent or mortgage payments while also trying to save for the future.

When money stress meets winter blues

Put together, seasonal mood challenges and financial stress can compound. Feeling worn down by winter weather makes it harder to take proactive steps on your finances, while money worries can feed anxiety and low mood. It’s the combination that can make a day like Blue Monday resonate even if it’s not scientifically the “bluest.”

What you can do to protect your wellbeing

Here are practical, evidence-based steps you can take this winter to boost both your mental health and your financial well-being.

Check in with yourself and others

First, normalize how you’re feeling. Many people experience a low mood during the winter and money worries. If your mood worsens or you feel overwhelmed, reach out to a health professional or a trusted friend. You’re not alone.

Boost daylight exposure

Even on grey days, daylight helps regulate mood. Try to get outside during daylight hours, sit near windows when you can, or rearrange your space so more light reaches where you spend most of your time.

If getting natural sunlight is a challenge, consider purchasing a light therapy lamp. Research shows that bright light therapy using a specially designed light box that mimics natural daylight can help ease depressive symptoms during the winter. It works by influencing brain chemicals linked to mood and circadian rhythm, and many people with seasonal affective disorder notice improvement after regular morning use (4).

Studies have found that light therapy is a recommended first‑line treatment for SAD and can significantly reduce symptom severity compared with dim light (5).

Keep moving

Physical activity releases endorphins that can improve mood and energy. Aim for 20 to 30 minutes of movement a day, even if it’s a walk.

Build small financial habits

Financial stress can feel overwhelming, but small consistent steps can build confidence and control:

  • Create a simple budget and track where your money goes each month
  • Set up automatic savings, even small amounts, to build an emergency fund
  • Prioritize paying down high-interest debt where possible
  • If you feel stuck, consider working with a financial planner. Research finds Canadians with professional guidance feel more hopeful about their finances over time.

Reach out for support

If feelings of sadness or depression last more than a couple of weeks or interfere significantly with daily life, it’s important to seek support from a healthcare provider.

Remember this winter will pass

Blue Monday serves as a reminder that the third week in January can be tough, but it doesn’t define your year. With intentional steps and support, you can ease both the financial stress and the winter blues — and build resilience to enjoy brighter days ahead.
