CPAP mask tips for summer


As the weather gets warmer, wearing your CPAP mask can suddenly feel a lot less appealing. Some of our users have told us of discomfort when it gets hot – where your mask can cling to your face and trap the warmth. The humid air coming from the CPAP machine can intensify the sensation of heat, making for a sweaty, less enjoyable experience.

The good news is that with a few adjustments and tips, it’s possible to achieve a more restful and cool night's sleep. In this blog, we'll explore some CPAP mask tips tailored for the summer. 

1. Check your humidifier settings  

Using a lower humidifier setting during the warmer months may help prevent condensation from building up in your mask. This is commonly referred to as ‘rainout’. It happens when the heated air from your CPAP machine cools in your tubing, reaching your mask as water and making your face damp.

2. Choose the right mask

Selecting the appropriate CPAP mask is crucial for comfort, especially during the warmer months. Nasal pillows and nasal masks are generally less intrusive. Full-face masks, in comparison, may feel warmer on a hot day due to increased coverage.

3. Opt for lightweight, breathable materials

Consider using CPAP masks made from lightweight and breathable materials. ResMed masks are designed with summer comfort in mind, featuring breathable cushions and minimalistic designs to enhance airflow.

ResMed mask headgear is made of soft and durable Breathe-O-Prene™ material. Air flows through the fabric so that it ‘breathes’, drawing moisture away from the skin for your comfort. 

4. Clean your mask regularly

Summer heat can worsen problems related to mask hygiene. No one wants to wake up with a sticky mask in the morning. Keep your CPAP mask and accessories clean to prevent the build-up of sweat, oils, and bacteria that can irritate your skin. Use mild, fragrance-free soap and allow all components to air dry thoroughly.

7. Replace CPAP parts as recommended

Make sure you replace CPAP parts, such as filters, as recommended so that the air coming through your CPAP machine is fresh and clean.  

An easy way to keep on top of the replacement of your CPAP parts and accessories is to join our CPAP subscription service and you’ll no longer have to think about when you need to replace your mask, device filter and other consumables.

8. Keep extras on hand

If your CPAP mask and accessories are still drying due to the humidity in the air, it can be worth keeping a back-up on hand. Keeping your tubing dry is particularly important to help avoid rainout.

9. Stay hydrated

Hot weather can lead to dehydration, so it's essential to stay hydrated. Ensure you drink enough water throughout the day to prevent discomfort caused by a dry mouth or throat during CPAP therapy.

As temperatures get hotter over the summer period, staying comfortable and sticking with your CPAP therapy may get harder. Incorporating these tips into your routine, can help you to experience a cool and comfortable night's sleep with your CPAP therapy.
