Diet and exercise often take centre stage when we think about heart health. But new research suggests there may be an even simpler way to protect against heart conditions that can lead to strokes – and it’s something you might already do every day.
Now, a new study has found that maintaining good oral hygiene – specifically flossing – may significantly reduce the risk of stroke.
The link between flossing and heart health
The study, presented at the American Stroke Association International Stroke Conference, examined how regular flossing (more than once a week) affects the risk of strokes caused by blood clots or linked to an irregular heartbeat, such as atrial fibrillation (AFib).
Researchers found:
- A 22% lower risk of ischemic stroke, which occurs when blood flow to the brain is blocked.
- A 44% lower risk of cardioembolic stroke, where blood clots travel from the heart to the brain.
- A 12% lower risk of atrial fibrillation, a condition that increases stroke risk.
The study surveyed 6,258 participants about their dental habits and overall health. Of those who flossed regularly, 65% had never experienced a stroke or been diagnosed with an irregular heartbeat. Lead researcher Dr Souvik Sen, from the University of South Carolina School of Medicine, explained that flossing may reduce stroke risk by lowering oral infections and inflammation linked to hardened arteries.
While the study has yet to be peer-reviewed, the findings add to growing evidence that oral health is closely connected to cardiovascular well-being. Given the high cost of dental care, Dr Souvik highlights that flossing is “affordable, accessible, and easy to adopt” as a protective habit.
More health benefits of flossing
Beyond reducing stroke risk, flossing offers several additional benefits:
- Prevents plaque buildup – Plaque can accumulate between teeth, leading to cavities and gum disease. Flossing helps remove it before it hardens into tartar.
- Reduces the risk of chronic diseases – Gum disease has been linked to diabetes, respiratory disease, and rheumatoid arthritis.
- Prevents bad breath – Food particles left between teeth can decay, creating an unpleasant odour.
- Flossing supports oral health during menopause – Hormonal changes can make gums more sensitive and prone to inflammation, but Flossing can help maintain gum health.
When should you floss?
It doesn’t matter whether you floss in the morning or evening – dentists simply recommend doing it before brushing your teeth. This allows your toothbrush to remove loosened debris for a cleaner, fresher mouth.
If you don’t like using traditional floss, you can try interdental brushes or water flossers, which are just as effective. If you’re unsure which option is best for you, your dentist can provide guidance on the right tools for your teeth.
More simple habits with surprising health benefits
If you’re looking for other easy ways to improve your health, these small daily habits could make a big difference:
- Standing up every 30 minutes – Long periods of sitting can increase the risk of heart disease and diabetes. Even short movement breaks can improve circulation and lower blood pressure.
- Drinking water before meals – Hydration boosts metabolism and can help with portion control by making you feel fuller.
- Taking deep breaths – Deep breathing reduces stress, lowers blood pressure, and improves oxygen flow to the brain.
- Laughing more – Laughter releases endorphins, reduces stress hormones, and can improve heart health.
- Sleeping in a cool room – Cooler temperatures can improve sleep quality, regulate metabolism, and reduce the risk of obesity.
Taking a few minutes daily to floss and adopt other simple habits could have long-term benefits for your overall health – and may even help prevent serious conditions like stroke.
