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

15. Rapid Weight Gain from Reduced Mobility and Comfort Eating

The combination of reduced daylight, increased comfort eating, and skipping exercise often leads to rapid, sustained weight gain over the winter months. Excess weight, particularly central obesity, strains the cardiovascular system and is a major, progressive risk factor for the development and progression of kidney disease. You don't need a drastic diet. Focus on damage limitation: Swap refined carbs for fiber-rich legumes, walk indoors (mall or large home store) for 20 minutes, and use small plates. Preventing rapid gain is a compassionate, protective measure for your kidneys.

16. Ignoring the Risk of Cold Exposure on Dialysis Sites

For individuals undergoing dialysis, cold weather introduces a specific, serious risk: cold exposure to vascular access sites (fistulas or grafts). Extreme cold can constrict blood vessels, reducing blood flow to the access site, which increases the risk of clotting or damage. Maintaining good blood flow is crucial for the effectiveness of dialysis and the longevity of the site. Patients must ensure these areas are adequately protected from the cold using layers, sleeves, or gloves, even when indoors or traveling short distances to the clinic.
