Comfort and side effects

Taking Your CPAP Mask Off in Your Sleep: Why and How to Stop

Waking up with your mask off is common, especially in the first weeks. It usually points to discomfort: a mask that is too tight or leaking, dryness, or pressure that feels like too much. Fixing the comfort issue is the way to stop it.

Signs

  • Finding your mask on the pillow or floor in the morning
  • No memory of taking it off
  • Low usage hours in your app
  • Many mask on and off events

Common causes

Mask fit problems
F&P says a mask that is uncomfortably tight or so loose it leaks can make you take it off during the night.
Dryness or congestion
A dry mouth or blocked nose can wake you enough to remove the mask.
Pressure discomfort
If pressure feels too high or too low, you may pull the mask off half asleep.
Adjusting to the feel
ResMed notes it is common to remove the mask consciously or unconsciously because it still feels foreign.

Fixes to try, easiest first

  1. Put the mask back on every time you wake

    Each time you notice the mask is off, put it back on. This builds the habit and adds therapy hours. Keep the mask within reach.

  2. Refit the mask lying down

    Adjust the straps while lying in your sleep position with the air on. Not too tight, not too loose.

  3. Treat dryness and congestion

    Raise humidity, use heated tubing and saline spray if dryness or a stuffy nose is waking you.

  4. Use ramp or exhale relief

    If pressure feels intense when you wake in the night, ramp and exhale relief may make it easier to keep the mask on.

  5. Check your data

    The myAir score counts mask on and off events. ResMed notes many removals can indicate a problem with mask fit or sleep in general. Use it to see if your changes are helping.

  6. Ask about a different mask

    A different style or size may be more comfortable. Ask your equipment provider for a refitting.

  7. Talk to your doctor with your clinician

    If you keep pulling the mask off, ask your doctor to review your pressure settings and data.

When to call your doctor

Call your sleep clinician if you remove the mask most nights after the first few weeks, or if your usage hours are below 4 hours a night, which is the level Medicare and many insurers use to judge adherence.

Frequently asked questions

Why do I keep taking my CPAP mask off at night?

Usually because something is uncomfortable: fit, dryness, congestion or pressure. Fix those, and practice putting the mask back on when you wake.

Does time with the mask off count toward compliance?

No. The Sleep Foundation notes that only time with the mask on counts toward compliance.

Is it normal to take the mask off when I get up to use the bathroom?

Yes. ResMed notes everyone takes the mask off at least once. Just put it back on when you return to bed.
