In the UK, eight million people live with a cardiovascular disease, and more than half of Brits will develop a cardiovascular condition in their lifetime, according to the British Heart Foundation. Dr. Francesco Lo Monaco, a cardiologist, advises against using strong antibacterial mouthwash after 6pm because it can wipe out mouth bacteria that help produce nitric oxide, potentially raising blood pressure.
According to Daily Express - Health, Dr. Lo Monaco described how bacteria in the mouth convert compounds from food into nitric oxide, which keeps blood vessels flexible, but powerful mouthwashes can eliminate this bacteria, raising blood pressure when the body should be resting. He also advises against blue light exposure after 6pm because it can suppress melatonin, increasing oxidative stress in arteries over time.
According to Daily Express - Health, Dr. Lo Monaco described how bright blue-rich light in the evening suppresses melatonin, a protective antioxidant for blood vessels, leading to more oxidative stress over time. The other two things Dr.
Lo Monaco advises against after 6pm are not detailed in the available claims, leaving questions about the full scope of his recommendations. Specific evidence or studies supporting these claims about habits and heart health are not provided, and the impact compared to factors like diet and exercise remains unclear. Exceptions or variations based on individual health conditions are not addressed, and the time frame of 'after 6pm' may vary by time zone or lifestyle, though this is unspecified.
