Why Do We Get Sick More in Winter—and What Can You Do About It?
What’s Really Behind the Winter Wave of Illness?
It’s not just the cold air. Research shows that viruses like influenza thrive in low-humidity environments, which are common indoors during winter. Dry air can also weaken your body’s natural defenses by reducing moisture in your nasal passages, making it easier for pathogens to enter. Combine that with less sunlight (and lower Vitamin D levels) and more time spent indoors, and you have the perfect storm for seasonal sickness.

Does Your Immune System Slow Down in Cold Weather?
Studies suggest that cooler temperatures can influence immune response. When your body is exposed to cold, blood vessels constrict to conserve heat, which may reduce the efficiency of immune cells in reaching infection sites. Add holiday stress and changes in sleep patterns, and your immune system can feel the strain.
How Can You Strengthen Your Defenses Naturally?
The good news: small, science-backed habits make a big difference.
- Stay hydrated – Dry winter air increases water loss.
- Prioritize nutrient-rich foods – Vitamins C, D, and zinc are key for immune resilience.
- Get outside when possible – Even short bursts of sunlight help maintain Vitamin D levels.
- Manage stress – Chronic stress can suppress immune function.
For those who struggle to meet nutrient needs through diet alone, a high-quality multivitamin and trace mineral support can help fill gaps.
Why Does Skin and Hair Suffer in Winter—and How to Fix It?
Indoor heating and cold outdoor air strip moisture from skin and hair, leaving them dry and brittle. Hydration—inside and out—is essential. Drinking enough water and using mineral-rich sprays like Fulvic Mineral Mist can help restore balance naturally.
