Cold Weather Crisis: Everyday Habits That Put Unexpected Strain on Your Kidneys

11. Neglecting Annual Kidney Health Screenings—“Out of Sight, Out of Mind”

Preventive health checks often take a back seat during busy, unpredictable winters—especially if getting to the clinic feels inconvenient or risky due to weather. But the earlier you detect kidney strain, the more choices and control you have over your lifelong health journey. Many serious issues can be caught by simple tests before symptoms even begin. Consider scheduling routine kidney function screenings as part of your winter wellness plan. Telehealth appointments and drive-through labs are more available than ever, letting you get the info you need with minimal fuss. Framing screening as a gentle gift to your future self helps turn this “should do” into a habit worth celebrating.

12. Overusing High-Dose Vitamin C and Immune Boosters

It's common to load up on high-dose Vitamin C and zinc supplements to fend off colds during winter. While usually safe in moderation, excessive daily intake of Vitamin C (ascorbic acid) can metabolize into oxalate, which is normally filtered by the kidneys. In high concentrations, oxalate can contribute to the formation of kidney stones in susceptible individuals. Be mindful of the cumulative doses found across supplements, electrolyte mixes, and fizzy immune drinks. Focus instead on Vitamin C from whole food sources like citrus and bell peppers, and ensure you're drinking enough water to help flush any excess.
