7 Tips for Intermittent Catheter Users to Prevent UTIs in Winter

Cold temperatures bring challenges to catheter care, it creates conditions that can greatly increase the risk of urinary tract infections (UTIs)for people relying on intermittent catheterization. Dry air, heavier clothing, disrupted routines, and reduced fluid intake all work against good bladder health.

However, most winter-related UTI risks are preventable. With the right care strategy, you can protect your urinary health throughout the cold months. Here are 7 practical tips from Bever Medical, helping you navigate winter with comfort. 

Why Winter Increases UTI Risk for Catheter Users

A catheter-associated urinary tract infection (CAUTI) occurs when bacteria enter the urinary tract through the catheter. While intermittent catheters have a lower risk than indwelling catheters, winter conditions can raise that risk due to:

• Reduced hydration, leading to concentrated urine
• Dry, cracked skin that allows bacteria to enter
• Heavy or layered clothing that traps moisture
• Disrupted hygiene routines during travel or holidays
• Fewer or delayed catheterization sessions

Getting to know these seasonal factors is the first step toward prevention.

Tip 1: Stay Hydrated

Cold winter always keep people away from water, because cold weather suppresses thirst. However, dehydration is the main reason for users of intermittent catheters for men during the winter months.

When fluid intake is low, urine becomes concentrated and remains in the bladder longer, creating an ideal environment for bacteria. So, what to do to lower the risk? Bever Medical, as an experienced single-use catheter manufacturer, suggests:

• Aim for at least 2 liters per day, unless otherwise directed by your doctor
• Use reminders or hydration apps to stay consistent
• Choose warm options like herbal tea, warm lemon water, or low-sodium broth
• Avoid excessive caffeine and alcohol, which irritate the bladder

Pro tip: Pale yellow urine is a good sign of adequate hydration.

Tip 2: Don't Delay Catheterization Because of Heavy Clothing

Layers of thermals, trousers, and coats can make catheterization feel inconvenient—especially in public restrooms. But delaying your schedule can cause bladder over-distension, urine reflux, and infection. The practical way is:

• Stick to your catheterization schedule, no matter the season
• Choose adaptive or easy-access clothing when possible
• Plan ahead by identifying warm, accessible restrooms when traveling

Tip 3: Prioritize Hand Hygiene During Flu Season

Winter is the peak season for viruses and bacteria. High-contact surfaces increase the risk of transferring germs to your catheter during insertion. Following these tips helps prevent you from bacterial risks:

• Wash your hands with warm water and soap for at least 20 seconds.
• Dry thoroughly using a clean towel
• Apply fragrance-free moisturizer to prevent cracked skin, which can harbor bacteria

Tip 4: Use Single-Use, Sterile Catheters

With your immune system already under seasonal stress, winter is not the time to reuse catheters. Single-use catheters significantly reduce the risk of cross-contamination.

What to do:

• Use a new, sterile catheter for every insertion
• Consider switching to a closed-system catheter if available
• Dispose of used catheters properly after each use

Pro tip: Single-use systems provide an extra layer of protection during high-risk months.

Tip 5: Ensure Proper Lubrication to Prevent Micro-Trauma

Cold temperatures and indoor heating can dry out mucosal tissue and thicken lubricants. Inadequate lubrication increases friction, causing tiny urethral tears that allow bacteria to enter. You can:

• Use sufficient, high-quality catheter lubricant
• Warm lubricant packets in an inner pocket before use
• Consider hydrophilic-coated catheters for smoother insertion

Pro tip: Store lubricating gel catheters or gel packets in an inner pocket before use to bring them to body temperature.

Tip 6: Consider Tiemann Catheters if Insertion Becomes Difficult

Cold weather can cause muscles to tense, making catheter insertion harder—especially for men with enlarged prostates or urethral narrowing. In such cases, using a Tiemann catheter for men may provide a solution. Before using, please consider these conditions:

• Never force insertion
• Speak with your urologist if resistance increases
• Ask whether Tiemann-tip catheters are appropriate for your needs

Note: Please use the right catheter to reduce trauma and infection risk. 

Tip 7: Support Bladder Health from the Inside

Your bladder environment matters. Supporting it nutritionally can help reduce infection risk.

Helpful habits:

• Vitamin C or cranberry supplements (if approved by your doctor)
• Limit alcohol during holiday gatherings
• Eat hydrating foods like soups, fruits, and vegetables
