Why Winter Can Be Hard on Kidney Health
Cold, dry air and seasonal illnesses can create challenges for people with CKD. Winter may increase risks for:
- Dehydration
- Higher blood pressure
- Weakened immune response
- Electrolyte imbalances
- Flu, RSV, and COVID-19
- Reduced blood flow to dialysis access sites
Learning how early detection and management can help you manage chronic kidney disease all winter long.
Stay Warm Without Raising Blood Pressure
Cold temperatures cause blood vessels to constrict, which can increase blood pressure — a major concern for people with CKD or hypertension.
Tips for staying warm safely:
- Dress in warm layers instead of tight, heavy clothing
- Wear warm socks, gloves, and hats while outdoors
- Keep indoor temperatures consistent
- Avoid heating pads directly on a dialysis access site

Manage Hydration, Even If You Feel Less Thirsty
People often drink less water in winter because they feel less thirsty. However, hydration remains important for kidney function, blood pressure, and electrolyte balance.
For non-dialysis CKD patients:
- Drink small amounts of water regularly throughout the day
- Choose warm, non-caffeinated beverages
- Avoid sugary drinks and dark sodas
For dialysis patients: Follow your prescribed fluid limit exactly as instructed by your care team.
