Too much mouthwash may affect heart health. The daily mail of England reported on January 26 that a new study by Queen Mary College, University of London, found that frequent use of mouthwash can bring disastrous health consequences, increasing the risk of heart disease and stroke.
In the new study, Dr. amrita aruwalia and colleagues asked 19 healthy subjects to use corsodyl, a mouthwash, twice a day. The results showed that the blood pressure of the subjects significantly increased by 2 ~ 3.5 mm Hg a few hours after gargling. Chlorhexidine contains 0.2% of the fungicide chlorhexidine. The content of this substance in other antiseptic mouthwash is also basically the same. Chlorhexidine can also kill some “beneficial bacteria”, which can produce a small amount of nitrite, which plays an important role in blood vessel expansion. A small amount of nitrite can protect the heart and have a positive impact on human health. Commonly used sterilized mouthwash can reduce the nitrite level in the mouth by 90% and the nitrite level in the blood by 25%.
Dr. aruwalia analyzed and pointed out that although mouthwash has a small impact on blood pressure, it will have an important impact on the death rate and disability rate of heart disease and stroke. Independent studies show that if blood pressure rises by two points, the risk of death from heart disease will increase by 7%, and the risk of death from stroke will increase by 10%.
