๐ก CAUTION/NUANCE: Your sleep apnoea might be worse than your test showed.
Here's why: if you were tested on a weeknight, the test may have missed the peak.
Recent research dubbed it "social apnoea"
- OSA severity jumps 18% higher on Saturdays compared to Wednesdays.
- Weekend sleep-ins, alcohol, late meals, and irregular schedules all worsen breathing events during sleep.
- Weekend AHI (apnoea severity) runs 6% higher than weekdays
- Sleeping longer AND later on weekends? 55% higher OSA likelihood
- High night-to-night variability links to 34% increased cardiovascular risk
The problem? Most diagnostic tests capture just one night, often midweek. If your test showed "mild" OSA but you're still exhausted, this could be why.
The Bottom Line:
If you're testing for OSA, at least one night should include weekend data, paired with a sleep diary tracking your habits.
Are you using CPAP during the week but skipping weekends? That's exactly when you may need it most.
