CPAP Therapy During Winter: How to Stay Comfortable in Cold and Dry Conditions

Winter can be a challenging time for CPAP users.
The cold, dry air common in Europe during the winter months can make it harder to maintain nasal comfort and consistent sleep therapy. Combined with seasonal colds and flu, CPAP users often experience dry nasal passages, congestion, and sleep disruption — but with the right setup, these issues can be prevented.

Why Winter Air Affects CPAP Therapy

One of the main functions of your nose is to warm and moisten the air you breathe.
When the air is cold, tiny blood vessels inside the nostrils dilate to warm the incoming air. This increased blood flow also causes narrowing of the airway and extra mucus production, which can lead to nasal congestion and a runny nose.

For CPAP users, this natural process can interfere with therapy by making breathing uncomfortable through the mask — especially if the air feels too cold or dry.

Simple Tips to Warm the Air You Breathe

If the air from your CPAP mask feels too cold or disrupts your sleep, try these simple remedies:

• Close the windows and heat the bedroom slightly before bedtime.
• Place the tubing under your bedclothes — your body heat will gently warm the air as it travels through.
• Use the dedicated humidifier designed for your CPAP device.
• Upgrade to a heated tube (climate line tubing) for a consistent air temperature and optimal humidity balance.

Tip: Most premium CPAP devices, such as Resmed AirSense™ 10 or 11, or Philips DreamStation 2, offer integrated humidifiers and heated tubing options. This combination helps maintain a steady climate inside your mask, regardless of room temperature.

CPAP Use During Colds and Flu

Sleeping with a cold, flu, or upper respiratory tract infection is never easy — and it’s even tougher when you use CPAP.
However, stopping your CPAP treatment during illness is not recommended, as untreated sleep apnea may worsen other symptoms like sore throat or fatigue.

If you experience ear pressure, pain, or any discomfort, contact your GP or sleep specialist before discontinuing therapy.

Remedies to Make CPAP More Comfortable When You’re Sick

• Use a saline nasal spray to moisturize and clear sinus passages.
• Consider a decongestant, but start early in the evening so it takes effect by bedtime.
• Try an over-the-counter nasal spray like Beconase (for short-term use only, up to three days).
  Always consult your pharmacist before use, especially if you’re taking other medications.
• Never add oils or decongestants (like Olbas oil) to your humidifier or filter — this can damage your CPAP device.

Use a Full Face CPAP Mask When Congested

Most CPAP users prefer nasal masks, but when congestion strikes, mouth breathing often follows.
This can cause air leaks, dry mouth, and reduced therapy effectiveness.

Switching to a Full Face CPAP Mask during illness ensures that your treatment remains effective even if you breathe through your mouth. It also prevents “mouth leak,” which can cause dryness, nasal congestion, and flu-like symptoms upon awakening.

Pro tip: Keep a full-face mask handy as a backup during the winter season or cold episodes.

The Importance of Heated Humidification

Using heated humidification is the most effective way to prevent dryness, nasal congestion, and irritation during winter CPAP therapy.

A humidifier warms and moistens the air before it reaches your airways, easing inflammation and making breathing more comfortable — especially in cold European climates.

Watch Out for “Rainout” (Condensation in the Tube)

When warm, moist air from your humidifier cools down inside the tubing, it can form water droplets or condensation — known as “rainout.”
This can cause gurgling noises or even water reaching your mask.

Upgrade Your Winter Setup: Humidifier + Heated Tube

If you live in a cold or dry climate, or experience discomfort from dry air, upgrading your setup can make a huge difference:

Benefits of Using a CPAP Humidifier and Heated Tube:

• Prevents dry nose, mouth, and throat
• Reduces nasal congestion and sinus irritation
• Maintains consistent temperature and humidity throughout the night
• Eliminates rainout and gurgling sounds in the hose
• Enhances overall comfort and therapy compliance
