Why Kidney Stones Risk Rises in Winter
During the colder months, many people unintentionally reduce their water intake because they don’t feel thirsty which can concentrate urine, increasing the chances of kidney stone formation. Studies even show a seasonal spike in kidney stone cases during winter.
Six Doctor-Recommended Tips to Prevent Kidney Stones in the Cold
Here are the six simple, effective ways doctors suggest protecting your kidneys during winter:
- Stay Hydrated, Even if You Don’t Feel Thirsty
- Make a conscious effort to drink enough water daily reduced thirst in winter puts people at risk of dehydration.
- If plain water feels boring, consider warm herbal teas or clear soups to boost fluid intake.
- Cut Back on Sodium and Animal Protein
- A diet high in salt increases calcium in urine, which elevates kidney stone risk.
- Limit excessive consumption of meat and replace it with more plant-based proteins.
- Watch Oxalate-Rich Foods
- Some foods like spinach, nuts, and chocolate are high in oxalates, which can combine with calcium to form stones.
- Moderation is key you don’t need to cut them out completely, but balance them with calcium-rich foods.
- Add Citrate-Rich Foods to Your Diet
- Citrus fruits such as lemons and oranges are great because citrate helps prevent the formation of calcium stones.
- Stay Physically Active
- Regular activity even walking or light exercise boosts kidney function and helps flush out minerals.
- Try to get at least 30 minutes of movement daily, even indoors if it’s too cold.
- Get Checked If You’ve Had Stones Before
- For people with a history of kidney stones, regular test-ups can help catch early signs and prevent recurrence.
- Monitor your urine and follow up with your nephrologist to tailor a prevention plan.
What Doctors Are Saying (Expert Insight)
Dr. Uday Dipakrao Gajare, a consultant nephrologist, notes that reduced hydration in winter directly raises the risk of stone formation due to more concentrated urine. He stresses drinking at least 2–2.5 litres of water daily even when you’re not feeling thirsty.
