The Bathroom Habit That May Be Raising Your Blood Pressure

from The Habit Healers · host Laurie Marbas, MD, MBA

Is your mouthwash raising your blood pressure? In this episode of The Habit Healers Podcast, I’m breaking down nitric oxide, the Nobel Prize-winning molecule your body makes in real time to regulate blood pressure, blood flow, erectile function, brain health, and how your muscles handle blood sugar.Most of us have never heard of it, and yet nitric oxide is one of the single most important signaling molecules in your cardiovascular system. Research shows that daily antiseptic mouthwash use can wipe out the nitrate-reducing bacteria in your mouth that your body relies on to produce it, and short-term studies link this habit to rising blood pressure and a higher risk of prediabetes and hypertension.I’ll walk you through the two different systems your body uses to make nitric oxide, why one of them depends entirely on your oral microbiome, and the simple four-part protocol I give my patients to restore healthy nitric oxide production naturally, using food, movement, smarter oral care, and your breath.What you’ll learn in this episode:* Why nitric oxide is essential for healthy blood pressure, circulation, and endothelial function* How antiseptic mouthwash may be linked to hypertension and prediabetes* The highest-nitrate foods for lowering blood pressure naturally, including arugula, beets, and leafy greens* Why nasal breathing beats mouth breathing for cardiovascular and lung health* A simple “bee breath” practice that increases nitric oxide output from your sinuses* The role of nitric oxide in men’s health and erectile functionDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/the-bathroom-habit-that-may-be-raisingA Big Thank You To Our Sponsors:If you want the best supplement to help you on your plant-based journey, you have to try Complement: https://lovecomplement.com/?aff=62 Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe
