Exercise reduces blood pressure; however, new research finds the type of mouthwash you use can negatively affect this benefit.

The Nitric Oxide Factor
The connection between oral health and overall health has received more attention recently, and now may provide a key to blood pressure health.
“Scientists already know that blood vessels open up during exercise, as the production of nitric oxide increases the diameter of the blood vessels (known as vasodilation), increasing blood flow circulation to active muscles,” said lead author Dr Raul Bescos, Lecturer in Dietetics and Physiology at the University of Plymouth. “What has remained a mystery is how blood circulation remains higher after exercise, in turn triggering a blood-pressure lowering response known as post-exercise hypotension.
“Previous research has suggested that nitric oxide was not involved in this post-exercise response — and only involved during exercise — but the new study challenges these views.
“It’s all to do with nitric oxide degrading into a compound called nitrate, which for years was thought to have no function in the body. But research over the last decade has shown that nitrate can be absorbed in the salivary glands and excreted with saliva in the mouth.”
Oral Bacteria A “Key” To Opening Blood Vessels
“These findings show that nitrite synthesis by oral bacteria is hugely important in kick-starting how our bodies react to exercise over the first period of recovery, promoting lower blood pressure and greater muscle oxygenation,” said study co-author Craig Cutler.
“In effect, it’s like oral bacteria are the ‘key’ to opening up the blood vessels. If they are removed, nitrite can’t be produced and the vessels remain in their current state.
“Existing studies show that, exercise aside, antibacterial mouthwash can actually raise blood pressure under resting conditions, so this study followed up and showed the mouthwash impact on the effects of exercise.
