As winter gets here, it not only sets a cooler temperature but also brings in obstacles for people with Chronic Kidney Disease (CKD). Recognizing that circulation, immunity, and blood pressure are all important aspects of managing CKD, colder weather can make health issues worse, Dr. Aviral Shah, MBBS, MD Medicine, Consultant Nephrologist at NephroPlus and Sr. Nephrologist at ESI Hospital told Financial Express.com.

Understanding these dangers and taking proactive measures to preserve their health during the season are essential. A research by The National Library of Medicine, says that the low temperature exposure can induce a decrease in the body’s immune function and lead to the common cold, the infectious status of which may be related to kidney damage.

“Additionally, low temperature exposure can also induce hypovolemia, atrial dysrhythmias, and cold diuresis, which may intensify the kidney burden and cause kidney damage. Therefore, high and low temperatures may be related to CKD. Such patients are especially vulnerable to dehydration due to dietary fluid limitations or diuretic drugs. This can disrupt electrolyte balance and compromise renal filtration,” Dr. Shah said.

CKD patients are impacted by winter weather in a number of ways. Blood vessel constriction brought on by cold temperatures tends to raise blood pressure, which further jeopardizes kidney function.

“Wintertime sun exposure reduction may also result in decreased vitamin D levels, which could impair immunity, making them more vulnerable to seasonal illnesses like the flu and pneumonia, which can be particularly serious and result in chronic kidney-related problems. While poor circulation results in cold-induced pain in the extremities, cold weather can make blood vessels to contract, increasing blood pressure and further taxing the kidneys. Furthermore, calcium and phosphorus imbalances in CKD patients frequently result in bone health problems, which might be made worse by the winter’s decreased sunlight exposure,” he said.

Therefore, winter safety and health can be improved for CKD patients by taking the following precautions:

Protecting Your Body in Cold Weather

Winter’s chill requires extra vigilance for kidney patients. Your access site needs particular attention during cold weather – whether you have a fistula or catheter, keeping it warm and protected is essential.

“Dress in layers, paying special attention to your extremities. Warm socks, insulated gloves, and a cozy hat become your allies against the cold. In your home, maintain a consistent temperature between 68-72°F (20-22°C) to prevent your body from working too hard to stay warm,” he said.

Strengthening Your Defence Against Winter Illness

Winter brings an increased risk of infections, which can be particularly challenging for kidney patients. Getting your annual flu shot and staying current with other recommended vaccinations is your first line of defense. Make hand hygiene a top priority – carry hand sanitizer and wash your hands frequently with soap and water.

During the height of cold and flu season, consider wearing a mask in crowded indoor spaces and try to maintain some distance from people who are visibly ill.

Nourishing Your Body Wisely

Winter eating requires thoughtful planning when you’re managing kidney disease. Cold weather can mask thirst signals, making it easier to overconsume fluids without realizing it. Track your fluid intake even more carefully than usual. Warm, kidney-friendly foods can provide comfort while staying within your dietary guidelines. Consider low-sodium broths, warm apple cider (counted in your fluid allowance), and hot meals centered around approved proteins and vegetables. Keep portion sizes in check, even during holiday celebrations.

Staying Active Despite the Weather

Physical activity remains important during winter months, but you’ll need to adapt your routine. Indoor exercises can be both safe and effective – gentle stretching, stationary cycling, and walking in place are excellent options. Create a comfortable indoor exercise space where you can maintain your routine regardless of weather conditions. Aim for about 30 minutes of activity most days, but always respect your body’s limits and your healthcare team’s recommendations.

Caring for Your Mental Health

Winter can affect your emotional well-being, especially when managing a chronic condition. The shorter days and longer nights might impact your mood, making it crucial to maintain social connections and engage in activities you enjoy. Consider using a light therapy lamp to combat winter blues, and practice stress-reduction techniques like deep breathing or gentle yoga. Joining support groups for kidney patients can provide both emotional support and practical tips for winter
management.

Managing Medical Care Through Winter Weather

Consistency in medical care becomes more challenging but even more critical during winter. Never skip dialysis sessions, even when weather conditions are difficult. Develop a winter weather plan that includes backup transportation options and knowledge of your clinic’s weather policies. Keep a current list of medications and maintain an adequate supply in case weather delays prevent you from reaching the pharmacy. Monitor your blood pressure regularly and keep detailed records to
share with your healthcare team.

“CKD patients can protect their health from winter-related difficulties by following these precautions. A few preventive steps can make all the difference, from controlling blood pressure and preventing dehydration to strengthening immunity through nutrition. By taking these actions, people with CKD can concentrate on remaining cozy, healthy, and resilient all winter long,” he told Financial Express.com.
