Summary: New research from Flinders University shows a significant connection between regular snoring and uncontrolled hypertension, particularly in overweight middle-aged men. The study used home-based monitoring technologies to track snoring and blood pressure in over 12,000 participants. Findings indicate that those who snore for more than 20% of the night are more likely to have uncontrolled hypertension. The study highlights the need to consider snoring in clinical care and hypertension management.
Key Takeaways:
- Regular snoring is linked to elevated blood pressure and uncontrolled hypertension, especially in overweight middle-aged men.
- Individuals who snore frequently at night have nearly double the risk of uncontrolled hypertension compared to non-snorers.
- The findings emphasize the importance of addressing snoring in the management of hypertension and other sleep-related health issues.
That loud snoring keeping you up at night could be more than a noisy annoyance—it could be an early warning sign of hypertension.
New research from Flinders University sleep experts found that people, particularly overweight middle-aged men, who regularly snore at night are more likely to have elevated blood pressure and uncontrolled hypertension.
The study, published in Nature Digital Medicine uses multiple night home-based monitoring technologies over a prolonged period to explore the association between snoring and hypertension.
Key Findings and Health Implications
“For the first time, we can objectively say that there is a significant connection between regular nighttime snoring and high blood pressure,” says lead author Bastien Lechat, PhD, from the College of Medicine and Public Health. “We found that 15% of all participants in the study, who were primarily overweight men, snore for more than 20% of the night on average and that this regular nightly snoring is associated with elevated blood pressure and uncontrolled hypertension. These results emphasize the significance of considering snoring as a factor in healthcare and treatment for sleep-related issues, especially in the context of managing hypertension.”
Study Methodology and Future Directions
Snoring is a common occurrence and is often underestimated in terms of its negative health implications. Snoring and sleep apnea often overlap indicating shared common causes.
“We observed that in those who snore regularly the risk of having uncontrolled hypertension was almost double. This risk almost doubled again in people who snored regularly and had sleep apnea versus those who did not snore regularly,” says Danny Eckert, PhD, director of sleep health at Flinders University and senior author of the paper, in a release.
Snoring alone may also serve as an early warning sign of high blood pressure, as poor sleep quality due to snoring may worsen the risk of hypertension. Hypertension can lead to serious health problems such as heart failure, stroke, heart disease, or kidney disease.
The study used sleep tracker data collected by an under-mattress sensor to detect snoring and sleep apnea, along with a US Food and Drug Administration-registered at-home blood pressure monitor in more than 12,000 participants globally over a nine-month period.
“This is the largest study to date investigating the potential relationships between snoring, sleep apnea, and hypertension using objective assessments in people’s homes, and it reveals important insights into the potential consequences of snoring on hypertension risk,” says Lechat in a release. “It also highlights the need to consider snoring as part of clinical care and management of sleep problems, particularly in the context of hypertension management. The findings of this study pave the way to further investigate whether therapeutic interventions directed toward snoring can reduce hypertension and reduce the risks associated with it.”
