Every time your breathing pauses in sleep, your oxygen dips — and your heart pays the bill.
The short version
- Breathing pauses cause oxygen dips; your body responds with stress hormones and blood-pressure spikes.
- “Hypoxic burden” measures the total low-oxygen strain your body absorbs each night — depth and duration together.
- Our reports track your hypoxic burden every night, because it’s one of the best clues to long-term heart health.
The nightly stress test you never signed up for
When oxygen falls, your body sounds an internal alarm: adrenaline surges, blood pressure spikes, your heart races. A few alarms a night is manageable. Dozens every hour, every night, for years — that’s a load your heart and blood vessels feel. Untreated sleep-disordered breathing is linked to high blood pressure, heart disease, and stroke risk.
Why we measure hypoxic burden
Older sleep measures mostly counted events per hour. Hypoxic burden goes further: it captures how deep your oxygen dips go and how long they last — the total strain, not just the count. Research increasingly ties it to cardiovascular outcomes. Every airway.dental/ report includes your oxygen picture in plain language, so you can watch it improve as treatment takes hold.
