Winter prep for CF: How cold weather affects CF

When colder months arrive, the shift in weather can bring additional challenges for people with cystic fibrosis (CF), as cold, dry air and seasonal illnesses can strain the lungs and complicate daily routines.

Fortunately, if you have CF, with some preparation, you can take steps to support your health and stay comfortable throughout the winter.

Why cold weather matters with CF

Breathing in cold, dry air may cause the airways to tighten and become irritated. For those living with CF, this can sometimes increase coughing or make the mucus in the lungs feel thicker. Moving quickly between heated indoor spaces and chilly outdoor air can also strain the respiratory system.

Winter is peak season for respiratory infections such as the flu and common cold. These illnesses are common causes of lung infections, which may lead to complications for people with a CF diagnosis. This is why taking extra precautions against infection becomes especially important during this time of year.

Tips to protect your lungs

Making small changes in your daily routine can help lessen the impact of winter air:

• Cover your face outdoors: A scarf or mask may warm and humidify the air before it reaches your lungs.
• Add moisture indoors: Heating systems often dry out the air. A humidifier may help make breathing more comfortable.
• Adjust activity as needed: Exercise in cold air may cause increased coughing. Consider shorter sessions or moving the activity indoors when temperatures are low.

These simple steps can make it easier to manage respiratory challenges associated with living with CF during the colder months.

Reducing risks during flu season

Because people with CF can be more vulnerable to respiratory infections, flu season requires extra attention. CF care teams often suggest an annual flu vaccination and staying current with other recommended vaccines for added protection.

Other helpful habits include washing your hands regularly, wearing a mask in crowded spaces, and limiting close contact with anyone who is sick. Keeping tissues, sanitizer, and cleaning wipes handy can make it easier to follow these practices consistently.

Keeping treatments on track

The busy holiday season and shorter daylight hours can sometimes disrupt routines. However, it is essential to continue airway clearance and your prescribed treatments during winter.

Creating a specific space at home for treatments and keeping your supplies organized can help you stay on schedule, even during travel or family gatherings.

Supporting your overall well-being

Winter can also affect energy and mood due to fewer daylight hours and more time indoors. Staying active, maintaining social connections, and supporting your body with balanced meals and enough fluids can all strengthen your physical and mental health.

Ultimately, while cold weather may create challenges for people with CF, preparation can make a difference. By protecting your lungs from dry air, lowering your exposure to seasonal viruses, and keeping treatments consistent, you can better manage the causes of winter-related flare-ups and support your health all season long.
