Morning Headaches with CPAP? Causes and Solutions
CPAP is supposed to make mornings better. So why do you have a headache?
Morning headaches have several possible causes. Let's figure yours out.
Possible Causes
Mask Too Tight
Signs:
- Headache focused where straps sit
- Forehead or temple pain
- Marks or indentations on face
Fix: Loosen headgear. The mask should seal gently.
Sinus Pressure
Signs:
- Pain around eyes, cheeks, forehead
- Worse when bending over
- Nasal congestion too
Fix: Address congestion (see nasal congestion article), saline rinse, consider allergy treatment
Pressure Issues
Signs:
- Waking with feeling of "head pressure"
- Headache plus other symptoms (bloating, ear popping)
Fix: Talk to provider about pressure settings
CO2 Retention (Rare)
Signs:
- Severe morning headaches
- Excessive sleepiness despite CPAP
- History of lung disease
Fix: See your doctor. May need different equipment.
Dehydration
Signs:
- Dry mouth also
- Not drinking enough water
- Headache improves with water
Fix: Drink more water throughout the day, ensure humidifier is working
Sleep Apnea Not Fully Treated
Signs:
- Still snoring
- Still tired
- Partner notices breathing issues
Fix: Review CPAP data with provider. May need pressure adjustment.
Step-by-Step Troubleshooting
- Check mask tension: Can you slip a finger under straps? If not, too tight.
- Review humidification: Dry air causes sinus headaches. Turn up humidity.
- Consider congestion: Stuffed nose? Treat it (see congestion solutions).
- Track patterns: Same every day? Only certain days? Write it down.
- Check your data: Is therapy working? High AHI despite CPAP?
When to See Your Doctor
Get medical attention if:
- Headaches are severe
- Accompanied by vision changes
- New and different from past headaches
- Not improving with adjustments
They may:
- Review your CPAP data
- Check for other conditions
- Adjust treatment
What Often Helps
Most common solutions:
- Loosening headgear
- Increasing humidity
- Treating nasal congestion
- Staying hydrated
- Ensuring CPAP is working properly
Headaches from Sleep Apnea
Remember: Untreated sleep apnea causes morning headaches too.
Before CPAP: Low oxygen, disrupted sleep = headaches
With CPAP: Usually fewer headaches
If headaches started with CPAP: Probably equipment-related (fixable!)
If headaches continue despite CPAP: Therapy may need optimization
