Everyone knows Canada is cold—no surprise there. But what many people might not realize is just how important the sun is, even on those bitterly cold days.
This past week, temperatures dropped to an icy -30°C, yet the sun was shining beautifully outside. The way the sunlight reflected off the snow was mesmerizing, almost magical. And, to my surprise, I felt much better on those sunny days than on previous ones, which, while not as cold, were completely overcast.
The Power of Sunlight in the Depths of Winter
The sun does so much more than just warm the air—it plays a crucial role in our well-being, especially in winter. One of its biggest contributions is helping our bodies produce vitamin D, which is essential for bone health, immune function, and even heart health. Studies show that vitamin D deficiency is linked to fatigue, mood swings, and a weakened immune system.

Without enough sunlight, many people develop Seasonal Affective Disorder (SAD), a form of depression that occurs during the darker months of the year. It’s no coincidence that I felt more energized on bright, sunny days, despite the freezing temperatures. The sun directly affects serotonin production, which helps regulate mood and combat feelings of lethargy and sadness.
The Stunning Visual Effect: A Boost for the Mind
There’s also something uniquely uplifting about the way the sunlight interacts with the snow. The crisp white landscape, bathed in golden light, creates a breathtaking scene that lifts the spirit. It’s like nature’s way of reminding us that beauty exists even in the coldest, harshest conditions.
Studies suggest that exposure to bright natural light, even in snowy conditions, can help regulate our circadian rhythm—the internal clock that controls sleep, energy levels, and mental clarity. That explains why I felt noticeably better on those bright, frigid days compared to the gray, gloomy ones.
Making the Most of the Winter Sun
Experts recommend getting as much natural sunlight as possible, even in winter. According to the Canadian Dermatology Association, around 15 to 30 minutes of sun exposure on the face and hands per day (even through cloud cover) is enough to boost vitamin D levels.
Here’s how I make sure to soak up the sun during winter:
✔️ Go for a short walk during daylight hours. Even if it’s freezing, a brisk walk in the sun can do wonders for energy levels and mood.
✔️ Sit by a window when indoors. If it’s too cold to go out, sitting near a bright window can still provide some benefits.
✔️ Use light therapy if necessary. Many Canadians use light therapy lamps to mimic natural sunlight and combat the effects of winter darkness. (Source: Mayo Clinic)
Final Thoughts
The winter sun may not bring warmth, but it brings something just as valuable—light, energy, and a boost to our well-being. Those bright, icy days remind me that even in the coldest conditions, the sun has the power to revitalize, inspire, and uplift.
So, if you’re experiencing a harsh Canadian winter, don’t underestimate the power of sunlight. Bundle up, step outside, and let that golden glow remind you that even the coldest days have their warmth.
