英媒起底 美国人多久换一次内裤 真相是(3)

纽约大学微生物和病理学教授Philip M. Tierno认为，两天不换内裤也没那么可怕。
Generally speaking, it’s not going to hurt you as much as your hygiene may hurt your reputation, Tierno told TODAY.
“一般来说，这不会对你身体有什么损害。损害更多的可能是你的名声。” Tierno说。
Everyone has naturally-occurring microorganisms in and on their bodies called a microbial flora, he said. While the fact that these microbes exist on the body may sound scary, the relationship between the host and organism is generally beneficial.
他说，每个人身上都有自然存在的微生物，称为微生物菌群。虽然身上存在微生物听起来很可怕，但它们和宿主的关系通常是有益的。
Since they are your bacteria, unless you have a break in the skin or another conduit of entry into the body they won’t do you harm, Tierno said.
“因为它们是你自身携带的细菌，除非你皮肤有伤口或者有其他进入你体内的渠道，否则它们不会对你造成伤害，”Tierno说。

Two days would probably be very little detection unless you grossly contaminate your underwear, said Tierno. If you talk about a week or two, now we’re getting into robust growth of organisms and clearly there will be odor.
“两天不换内裤很难被察觉，除非你把它弄脏了，”Tierno说。“但是如果你说一两周不换，微生物大量繁殖就一定有味道了。”
Tierno explained that as long as the person clean well after using the restroom, theres no need to fear harm from extended undergarment wear.
Tierno解释说，只要在使用洗手间后清洁干净，就不必担心换不换内裤。
