生活小常識：浴巾到底該多久洗一次？

I hate to break it to you, but your bath towel is dirty – really dirty.
我並不想和你講，但你的浴巾真的髒了。

The moment you use it, it becomes a breeding ground of bacteria; fungi; dead skincells; salivary, anal and urinary secretions; and many other germs lingering in your bathroom that may have hopped onto your towel – including droplets fromyour toilet.
你用毛巾的那一刻，毛巾就成了細菌的溫牀，有死皮細胞、唾液和尿液分泌物，還有其它細菌在你的衛生間揮之不去，或許就一躍而上到了你的毛巾上，包括你馬桶上的點點滴滴亦如此。

While most of these microbes aren't likely to harm you, given that most of them probably came from your own body, they're there, and they're multiplying quickly.
儘管多數微生物並不會危害你，因爲多數來自你的身體。微生物就在那兒，飛速成倍增長。

When you wick moisture from your body, the microbes and other secretions such as cellular debris that live on the surface of your body get deposited onto your towel.
身體水分蒸發時，身體表面的細胞碎屑和空氣裏的沉澱物等微生物和其它分泌物會沉積到毛巾上。

It's hard to say whether the microbes growing on your towel are harmful, since most germs in our households aren't dangerous.
很難說生長在你毛巾上的微生物是否有害，畢竟家裏多數細菌並不危險。
美國環境健康教授olds說：“浴巾用完，每次都晾曬的話，可以重複使用3次。”

勤快清洗的話，一條浴巾你可以用上10年！
