Feeling that seasonal fatigue? See how red light therapy plus vitamin D can recharge you, lift your mood, and keep you glowing through Calgary’s winter months.
As daylight shortens during Calgary’s winter – dropping to roughly eight hours around the solstice – our immune defenses and energy can waver. Shorter days, lower sun angle, and more time spent indoors limit UVB exposure, which can affect vitamin D status. In fact, low winter sun exposure is linked to higher rates of vitamin D deficiency (StatsCan). Pairing red light therapy with targeted vitamin D support can be a practical way to stay energized and resilient through the darker months.
It’s about understanding how these different tools work in your body and why using them together gives you better results than relying on any single method.

Red Light Therapy vs. Vitamin D: Key Differences for Immune Support
Red light therapy and vitamin D support your health through completely different mechanisms. Vitamin D is a hormone your body produces when UVB rays hit your skin. It regulates calcium absorption, supports bone health, and plays a direct role in immune function. But here’s the problem: UVB rays are too weak in Calgary between October and April to produce sufficient vitamin D in your skin.
Red light therapy works differently. It uses specific wavelengths of light to activate cytochrome c oxidase in your mitochondria (PMC5215870), which increases ATP production and cellular energy levels. This process doesn’t create vitamin D, but it does support cellular repair, reduce inflammation, and help your immune system function more effectively. Red light therapy commonly uses red light at 660nm for surface-level support and near-infrared light at 850nm for
You need both during Calgary’s winter. Vitamin D addresses specific deficiencies that affect bone health and immune response. Red light therapy supports the cellular processes that keep your energy high and your body resilient. They complement each other rather than compete. deeper tissues and recovery (Block Blue Light).
Why Vitamin D Levels Matter for Your Overall Health
Vitamin D deficiency affects more Canadians than you might think. Statistics Canada data shows that vitamin D concentration below 30 nmol/L among Canadians more than doubles during winter months, jumping from 6% in summer to 13% between November and March.
You might get 3-4 hours of sunlight on a winter day (when you’re not working), but the angle of the sun means those rays lack the UVB intensity needed for vitamin D production. Your body simply can’t make what it needs from October through April.
Low vitamin D levels lead to weakened immunity, persistent fatigue, muscle weakness, and mood imbalances. These symptoms mirror what many people blame on “winter blues,” but they’re often rooted in measurable deficiencies that you can address.
Staying Energized in Calgary’s Darker Months
Maintaining energy during Calgary’s winter requires a multi-pronged approach. Red light therapy sessions provide consistent cellular support, but you need to pair them with other strategies for best results.
Start with light exposure timing. Get outside during the limited daylight hours when possible, even if the sun isn’t strong enough for vitamin D production. Natural light still helps regulate your circadian rhythm and supports mood. Then supplement with red light therapy sessions in the morning or early afternoon to support energy production without disrupting sleep.
Consider vitamin D supplementation after testing your levels with a healthcare provider. Most Calgary residents need 1,000–2,000 IU vitamin D daily during winter, but your specific needs depend on your baseline levels. Some people also choose vitamin injections or IV therapy to address deficiencies or support overall wellness.
Stress management becomes critical when daylight shrinks. Red light therapy supports your body’s stress response by improving cellular resilience, but you still need to address lifestyle factors. Regular sleep schedules, moderate exercise, and social connection all support the cellular processes that red light therapy enhances.
Some people benefit from combining multiple therapies. Therapy circuits that pair red light therapy with other modalities like oxygen therapy or lymphatic drainage can compound the benefits. The key is consistency rather than intensity.
Build Your Winter Wellness Plan
Don’t settle for slogging through Calgary’s dark months and Seasonal Affective Disorder (S.A.D) – create a coordinated strategy using red light therapy and vitamin D for real results. Each supports your immune system, energy levels, and mental health through different pathways. You don’t need to choose between them. The most effective winter wellness strategy uses both in a coordinated approach.
Red light therapy provides the cellular energy boost and immune support that helps you function at your best. Vitamin D addresses the specific deficiencies that Calgary’s winter creates.
