Starting CPAP therapy is a big adjustment, and it’s extremely common to still wake up several times a night during the first few weeks — even though the machine is doing exactly what it’s supposed to do. If you’ve just started treatment and are wondering why you’re not sleeping through the night yet, you’re far from alone, and there are usually identifiable, fixable reasons behind it.
Why early CPAP use can still feel disrupted
According to the Sleep Foundation, it commonly takes several weeks of consistent use before people fully adjust to sleeping with a CPAP mask and airflow. During this adaptation period, several things can contribute to fragmented sleep:
- Mask leaks or a poor seal, which can cause pressure fluctuations that wake you without you fully realizing why.
- Aerophagia — swallowing air during the night — which the Mayo Clinic notes is a recognized side effect some people experience when starting CPAP.
- Pressure settings that haven’t been fully dialed in yet, particularly in the first few nights before a titration or auto-adjusting algorithm has enough data.
- Simple unfamiliarity with sleeping while wearing a mask and hose, which the body and mind generally need time to adapt to.
What may help
The American Academy of Sleep Medicine and most sleep specialists generally suggest a few practical steps during this adjustment window:
- Use the “ramp” feature if your machine has one, so pressure builds gradually as you fall asleep rather than starting at full pressure immediately.
- Double-check mask fit — a refit at your equipment provider is often free and can resolve leak-related awakenings.
- Try heated humidification if you’re experiencing dryness or congestion, which can itself be a source of nighttime waking.
- Give it consistent time. Research summarized by the National Heart, Lung, and Blood Institute indicates that regular, nightly use is what leads to both symptom improvement and easier long-term adaptation — inconsistent use tends to prolong the adjustment period.
When it’s worth checking in with your provider
If frequent waking continues well beyond the first few weeks, or if your machine’s data shows a persistently high AHI (apnea-hypopnea index) or high leak rate, that’s a signal worth bringing to your sleep specialist or durable medical equipment (DME) provider rather than waiting it out indefinitely. Pressure settings sometimes need adjustment, and a different mask style may be a better fit for your face shape or sleep position.
