Snoring and High Blood Pressure: What the Studies Show

Research has linked snoring with high blood pressure, including in women. The relationship deserves attention, but a study showing an association does not establish that stopping snoring will lower blood pressure. This article explains a historical Nurses’ Health Study analysis and a more recent investigation.

The 1999 study in women

Hu and colleagues examined snoring and hypertension in a large cohort of US nurses. In their prospective analysis, the adjusted relative risk of developing hypertension was 1.29 for occasional snorers and 1.55 for regular snorers compared with non-snorers. The respective 95% confidence intervals were 1.22–1.37 and 1.42–1.70.

The association remained after accounting for several measured factors, including age and body size. This makes the finding relevant, but statistical adjustment is not proof that snoring alone caused the difference.

What does newer research add?

A 2024 study in npj Digital Medicine used repeated objective snoring measurements and daytime blood-pressure readings in a consumer sample. More snoring was associated with uncontrolled hypertension, including after accounting for estimated sleep-apnea severity. It supports further investigation of snoring as a health marker, rather than dismissing it as merely noise.

Important limits

• Association is not a treatment result. Neither finding demonstrates that an anti-snoring product lowers blood pressure.
• Study populations differ. Results from nurses or people using consumer monitoring devices may not apply identically to everyone.
• Measurements matter. Self-reported snoring, device estimates and a clinical sleep assessment are different sources of information.
• Risk is individual. A relative risk of 1.55 is not a 55% probability of developing hypertension.

What to discuss with your healthcare professional

If you have persistent snoring, mention it during a blood-pressure review, especially if you also have breathing pauses, gasping or daytime sleepiness. Ask whether sleep-apnea assessment is appropriate. Continue your prescribed blood-pressure and sleep-apnea treatment unless your clinician advises a change.

For the related cardiovascular question, see our separate explanation of snoring and cardiovascular disease in women. That study examined heart disease and stroke, rather than the onset of hypertension.

What can be claimed about Asonor?

These studies did not evaluate Asonor. They must not be used as evidence that it treats hypertension or prevents cardiovascular disease. A reduction in snoring is not a substitute for blood-pressure measurements or clinical assessment.
