Starting CPAP therapy is supposed to be the moment sleep apnea gets easier to manage — but for a lot of people, the first few months feel like the opposite. Waking up repeatedly through the night, a sensation of not getting enough air, or simply not being able to tolerate the mask are common enough complaints that sleep medicine researchers have a name for the broader problem: CPAP non-adherence. Studies cited by the Sleep Foundation estimate that a meaningful share of new CPAP users stop using their device regularly within the first year, often because of exactly these kinds of early struggles.
Why CPAP can feel miserable at first
According to the Mayo Clinic and the American Academy of Sleep Medicine (AASM), a few issues tend to explain most of the discomfort people report:
- Mask fit and type. A mask that’s technically “sealed” can still feel wrong — too much pressure on the bridge of the nose, air leaking into the eyes, or a style (full-face vs. nasal vs. nasal pillow) that doesn’t suit how someone breathes or sleeps.
- Pressure settings. Some people feel like they’re fighting the machine to exhale, a sensation formally addressed by pressure-relief features many modern devices include.
- Aerophagia (swallowed air). Waking up feeling bloated or gassy is a well-documented side effect that’s related to pressure and can sometimes improve with positioning or setting adjustments made by a clinician.
- Humidity and dryness. A dry mouth or irritated airway can itself cause awakenings, which is why most machines include adjustable heated humidification.
- Psychological adjustment. Feeling “suffocated” by a mask is a recognized adjustment hurdle, sometimes addressed through gradual desensitization — wearing the mask for short periods while awake before sleeping in it.
It’s also worth knowing that waking up multiple times a night doesn’t automatically mean the therapy has failed. Many modern machines log data — including residual events per hour (AHI) — that a sleep clinic or durable medical equipment (DME) provider can review remotely. Bringing that data to a follow-up appointment is one of the most useful things a person can do, since it turns “this isn’t working” into a specific, fixable issue for a clinician to look at.
What tends to help, per sleep medicine guidance
Based on general guidance from the Sleep Foundation and the AASM, some commonly discussed troubleshooting steps include:
- Trying a different mask style or size — many DME suppliers allow exchanges specifically because first-mask mismatch is so common.
- Asking a sleep specialist about auto-adjusting pressure (APAP) or bilevel (BiPAP) settings if a fixed CPAP pressure feels hard to tolerate.
- Increasing humidification gradually rather than leaving it at a default setting.
- Practicing “mask desensitization” — wearing the mask while reading or watching TV before attempting to sleep in it.
- Ruling out other contributors to poor sleep, such as nasal congestion, allergies, or an anatomical issue an ENT could evaluate.
If someone has genuinely tried these adjustments with professional support and CPAP still isn’t tolerable, that’s a conversation worth having with a sleep physician about alternatives — oral appliance therapy, positional therapy, or in some cases surgical options — rather than simply going untreated, since untreated sleep apnea carries its own well-documented health risks according to the CDC.
