Heart health is something many of us are concerned about, especially since heart disease remains one of the leading causes of death worldwide. We’re often told to focus on diet, exercise, and stress management to protect our hearts, but what about everyday habits we overlook? According to Dr. Jeremy London, a cardiac surgeon, there’s one common item many people use daily that he “absolutely avoids”—and it might not be what you expect. Let’s uncover why this surprising item is on Dr. London’s no-go list.
Why Dr. London Says ‘No’ to Mouthwash
When you think of things that could affect heart health, mouthwash probably doesn’t come to mind. Yet, Dr. London has gone public about why he avoids this seemingly harmless product as part of his daily routine.
The Impact of Mouthwash on Good Bacteria
Dr. London emphasizes that the mouth is part of the gastrointestinal tract and contains beneficial bacteria, just like your gut. These “good” bacteria play a vital role in maintaining the overall balance in your mouth. When you use mouthwash, especially those with strong antibacterial agents, you can inadvertently kill these helpful bacteria.
- Why It Matters: Your oral microbiome (the community of bacteria in your mouth) does more than just support oral hygiene. It’s involved in critical bodily functions, including the regulation of blood pressure. Some bacteria in your mouth help produce nitric oxide, which supports the relaxation of blood vessels, thereby helping to maintain healthy blood pressure levels.
Mouthwash and Blood Pressure: The Unexpected Link
Dr. London explains that destroying healthy mouth bacteria can have a ripple effect on blood pressure. Here’s how it works:
- Chemical Reaction: The beneficial bacteria in your mouth help convert nitrates (found in foods like leafy greens) into nitric oxide. This compound helps dilate blood vessels and lower blood pressure.
- Increased Risk: By disrupting this process, frequent use of mouthwash can inadvertently contribute to higher blood pressure—a major risk factor for strokes, heart attacks, and other cardiovascular diseases.
The connection between mouth bacteria and heart health is more direct than many of us realize. In fact, a study published in Frontiers in Cellular and Infection Microbiology highlighted that mouthwash use could potentially hinder blood pressure regulation.
When to Use Mouthwash (If at All)
If you still want to use mouthwash for fresher breath, Dr. Zaeem Jafri, a dentist with Ordo, suggests being mindful of when and how you use it. According to Dr. Jafri:
- Don’t Use It After Brushing: Mouthwash, even when it contains fluoride, is less concentrated than toothpaste. Using it immediately after brushing can wash away the concentrated fluoride, reducing its protective effects on teeth.
- Use It Separately: Instead, use mouthwash at a different time of day, such as after lunch, to freshen your breath without interfering with your oral health.
- Stick to Fluoride-Containing Mouthwash: If you use mouthwash, choose one with fluoride to help prevent tooth decay.
The NHS echoes this advice, recommending that mouthwash be used at least 30 minutes before or after brushing to maximize the benefits of fluoride toothpaste.
Other Surprising Factors That Affect Heart Health
While mouthwash may not seem like a major factor in cardiovascular health, it’s a reminder that everyday habits can have unexpected consequences. Let’s look at some other common items and habits that can impact heart health.
1. Excessive Caffeine Consumption
Many people start their day with a cup of coffee (or three), but too much caffeine can be tough on the heart. High caffeine intake can increase blood pressure, cause palpitations, and contribute to anxiety—each of which can strain the cardiovascular system.
- The Heart Health Tip: Limit caffeine intake to moderate levels and avoid consuming it close to bedtime. Opt for decaf or herbal teas in the afternoon to reduce overall caffeine consumption.
2. High-Sodium Diet
Sodium is a well-known culprit when it comes to high blood pressure, which is a leading risk factor for heart disease. While many associate high sodium with salty snacks or fast food, it can also hide in everyday items like bread, canned soups, and even salad dressings.
- The Heart Health Tip: Pay attention to food labels and aim to keep sodium intake below 2,300 milligrams per day, as recommended by the American Heart Association.
3. Lack of Sleep
Sleep quality is directly linked to heart health. Inadequate sleep can contribute to increased blood pressure, weight gain, and higher stress levels—all of which can negatively affect your heart.
- The Heart Health Tip: Aim for 7-9 hours of quality sleep each night. Establishing a calming bedtime routine can improve your sleep patterns and support heart health.
4. Skipping Breakfast
Breakfast plays a crucial role in regulating metabolism and blood sugar levels. Skipping this meal can lead to overeating later in the day, contributing to weight gain and increased cardiovascular risks.
- The Heart Health Tip: Start your day with a balanced breakfast that includes protein, healthy fats, and whole grains to stabilize blood sugar and support overall wellness.
The Right Way to Prioritize Oral and Heart Health
While Dr. London warns against frequent use of mouthwash, maintaining good oral hygiene is still vital for overall health. Oral bacteria can enter the bloodstream, leading to inflammation and potentially increasing the risk of heart disease.
Better Oral Hygiene Practices
- Brush Twice Daily: Use fluoride toothpaste to brush your teeth twice a day for at least two minutes each time.
- Floss Regularly: Flossing helps remove plaque and food particles that can lead to gum disease, a risk factor for heart disease.
- Regular Dental Checkups: Visit your dentist every six months for cleanings and checkups to catch potential issues early.
By adopting these habits, you can protect your oral health without over-relying on mouthwash.
Conclusion: The Small Changes That Make a Big Difference
Dr. London’s advice about mouthwash may come as a surprise, but it underscores the importance of understanding how daily habits affect heart health. While maintaining good oral hygiene is essential, it’s equally important to be aware of the impact that products like mouthwash can have on your cardiovascular system. By being mindful of when and how you use mouthwash, and making small adjustments in other daily habits, you can improve both your oral health and your heart health. Sometimes, the path to better wellness begins with unexpected changes in our routines.
