运动后使用漱口水会弱化运动带来的好处


In ads on TV, people use mouthwash, it instantly neutralizes all the nasty bacteria hiding in their mouths, and – just like that – their dental hygiene is assured.

在电视机广告中,人们使用漱口水以后,隐藏在口腔中的有害细菌立刻就被清除了,从而令使用者的口腔卫生得到了保证。


But what's really going on when you rinse a cap-load of antibacterial chemicals around your mouth? What does that to your body, and to other kinds of microorganisms that may actually be beneficial to health?

然而,在现实中,当你用一瓶盖的抗菌化学品漱口时,究竟会发生什么呢?对你的身体有什么影响?对其他有益健康的微生物又会有什么影响呢?


As a study showed last year, the downstream effects of the simple act can be surprising, and far-reaching too, affecting much more than just your dental wellbeing.

去年一项研究表明,这个简单动作的下游效应令人意外且影响深远,影响的不仅仅是口腔健康。


In an experiment led by scientists from the UK and Spain, researchers found that using mouthwash after exercising can reduce one of the benefits of exercise: lowering blood pressure

英国和西班牙的科学家进行了一项实验,研究人员从中发现运动后使用漱口水这一行为会弱化运动带来的一项好处:降血压。


When you exercise, your blood vessels open in response to the production of nitric oxide, which increases the diameter of blood vessels. This process is called vasodilation, and it increases blood flow circulation to active muscles.

运动时,血管会因为一氧化氮的产生而张开,血管直径扩大。这一过程被称为血管舒张,能促进活跃肌肉的血液循环。


For a long time, researchers thought this only happened during exercise, but in more recent years, evidence has shown that circulation stays high (meaning blood pressure is lowered) even after exercise – thanks to how bacteria interact with a compound called nitrate, which forms when nitric oxide degrades.

很长一段时间,研究人员以为这只发生在运动期间。但近些年,有证据表明,甚至在运动之后血液循环依然保持较快的速率(这意味着血压下降了),这都归功于细菌和一种叫作硝酸盐的化合物间的相互作用。硝酸盐是在一氧化氮降解时形成的。


"Research over the last decade has shown that nitrate can be absorbed in the salivary glands and excreted with saliva in the mouth," explains physiology specialist Raul Bescos from Plymouth University.

普利茅斯大学生理学专家Raul Bescos解释说:“过去十年的一项研究表明,硝酸盐能被唾液腺吸收,并在口中随唾液分泌。


"Some species of bacteria in the mouth can use nitrate and convert into nitrite – a very important molecule that can enhance the production of nitric oxide in the body."

口腔中一些细菌可以利用硝酸盐,转换成亚硝酸盐,这种重要的微粒可以提高人体内一氧化氮的产量。


Once nitrite is produced and swallowed with saliva, it becomes absorbed into blood circulation and reduces back to nitric oxide, which keeps blood vessels wide and lowers blood pressure.

一旦产生亚硝酸盐,随唾液一同被咽下,进入血液循环中,被还原为一氧化氮,从而保持血管宽阔,降低血压。


But according to this study, it looks like this biological mechanism can be significantly interrupted if anti-bacterial mouthwash gets added into the post-exercise mix.

但这项研究指出,如果运动后喝抗菌漱口水,则会大大减弱这种生物学机制。
