洗手真的有用吗?

康妮·奥巴赫把这个交给了阿登布鲁克医院的谢丽尔·特伦德尔

谢丽尔:说到洗手，重要的是要知道什么时候洗手，用什么样的肥皂或洗手剂，以及怎么洗手。在这三者中，最重要的是好的技术，也就是你怎么做。任何肥皂都是足够的，任何肥皂都有效，但重要的是你要覆盖你的手的所有表面并且你要在规定的时间内这样做，你需要在接触病人之前和之后这样做。康妮:需要多长时间?我一直认为这取决于我有多匆忙。谢丽尔:一般来说是10到30秒。大概是你慢慢唱生日快乐歌的时间。康妮:到目前为止，戴尔，似乎你的清洁女工一直在撒谎。。那那个手势呢?谢丽尔:这样他们就不会碰任何东西了。 So they just hold them where they can see them so they're not touching anything dirty to contaminate them again. Then the water can wash down to the elbow so that the fingertips, which are the important bits, remain clean. It also lets the hands drain a bit so it doesn't take quite so long to dry them. Connie - Well, there you go Dale. There's some method to the madness but don't ditch the soap just yet.Next week we'll be defying time with Troy's question... Troy - If you were to live on Jupiter for fifty years and then return to Earth, what would the time difference be back on Earth due to Jupiter's increased gravity? Thank you.
