别在运动后用漱口水，会有反作用

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.

锻炼时，血管会因一氧化氮的产生而打开，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.

很长时间以来，研究人员以为这只发生在运动期间。但近些年，有证据表明甚至在锻炼之后血液循环依然很快（这意味着血压下降了），这都是因为细菌在和一种叫作硝酸盐的化合物发生相互作用。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."
