你每天使用的漱口水可能会悄悄地使你的血压危险地升高——尤其是近一半的美国成年人已经患有高血压。

一项针对健康志愿者的突破性研究发现，仅使用含氯己定的漱口水七天，就会导致部分参与者的收缩压飙升至25毫米汞柱以上，且停用后这种影响仍持续数日。其原因是：氯己定漱口水会清除口腔中将膳食硝酸盐转化为一氧化氮（一种能够放松血管、维持健康血压的关键分子）的必需细菌。

约有 2 亿美国人经常使用漱口水，越来越多的证据表明，保护这些硝酸盐还原微生物对于支持天然一氧化氮的产生和长期心血管健康至关重要。

Your daily antiseptic mouthwash might be quietly pushing your blood pressure dangerously higher—especially when nearly half of U.S. adults already live with hypertension.

Groundbreaking research on healthy volunteers found that just seven days of chlorhexidine-based mouthwash triggered systolic surges of up to over 25 mmHg in some participants, with effects lasting days after stopping. The cause: it eliminates essential oral bacteria that convert dietary nitrates into nitric oxide—the key molecule for relaxing blood vessels and maintaining healthy blood pressure.

With around 200 million Americans using mouthwash regularly, mounting evidence shows that preserving these nitrate-reducing microbes is critical for supporting natural nitric oxide production and long-term cardiovascular health.
