How Does Cold Affect Kidney Function?

As the cold weather settles in, it brings with it a host of concerns, particularly for those living with chronic kidney disease (CKD). At Shifa Nephrology Associates LLC, located in the heart of Chicago’s vibrant West Town, we understand the unique challenges posed by winter months and their impact on kidney health.

Our holistic approach to kidney care, led by the compassionate and knowledgeable Dr. Farheen M. Shah-Khan, aims to provide patients with the best possible support during these cold months.

The Effects of Cold Weather on Kidney Function

The Journal of Occupational Health, Volume 66, Issue 1, January-December 2024, reported that individuals with CKD are more affected by exposure to extreme temperatures, including low temperatures, which can delay the normal hemodynamic response, affect the cardiovascular system, and lead to renal hypoperfusion.

For individuals with healthy kidneys, exposure to cold may lead the body to constrict blood vessels to conserve heat. This vasoconstriction can reduce blood flow to the kidneys, if prolonged, potentially impairing their function. For patients with CKD, whose kidney function is already compromised, this can be particularly problematic. The kidneys play a crucial role in regulating blood pressure, filtering blood and maintaining fluid balance. Thus, any decrease in blood flow can exacerbate existing issues.

Moreover, cold temperatures can lead to dehydration, often overlooked in winter. People tend to drink less water during colder months, which can lead to lower fluid intake. Dehydration can strain the kidneys further, potentially leading to acute kidney injury, especially for those already living with CKD.

Winter can also be a time of increased respiratory illnesses, like colds and flu, which may require medication that could be nephrotoxic—harmful to the kidneys. Therefore, managing exposure to infections and medications carefully is vital for those with CKD during the winter.

Holistic Kidney Care at Shifa Nephrology Associates

At Shifa Nephrology Associates, we emphasize the significance of holistic kidney care. Our expert team is committed to addressing not only our patients’ medical needs but also their overall well-being. Under the guidance of Dr. Farheen M. Shah-Khan, we focus on personalized care that incorporates dietary advice, management strategies, and preventive measures that account for the impacts of cold weather.

Some of our approaches include:

• Nutrition Guidance: We provide tailored dietary plans that help maintain kidney health, especially in winter. For example, ensuring adequate fluid intake, even in cold weather, is crucial. We can help our patients identify healthy sources of hydration and monitor phosphorus and potassium intake.
• Blood Pressure Management: Because blood pressure can fluctuate in colder temperatures, we educate our patients on the importance of regularly monitoring their blood pressure, especially if they are on diuretics or other CKD medications.
• Medication Review: We encourage regular consultations to review any medications patients may be taking, especially those that could negatively affect kidney health during the winter months.
• Supportive Care: Our team is always here to offer compassionate support and answer questions, ensuring patients feel comfortable seeking help during the colder months.
• Personalized Advice: Every individual is unique. Our goal is to provide advice tailored specifically to each patient’s needs, helping them stay healthy and safe through winter.
