今天是全球洗手日（Global Handwashing Day），全球洗手日是促进用肥皂洗手公私伙伴组织（PPPHW）发起的，号召全世界各国从2008年起，每年10月15日开展用肥皂洗手活动。此前一份调查显示，仅7%城市居民保持良好洗手习惯。实际生活中，有很多接触细菌情境我们不知：每次进餐、如厕、接触钱币等情境下都要洗手；洗手时要使用流动水；洗手时要使用肥皂、香皂或洗手液等清洁用品；洗手时长不少于20秒等。

全球洗手日，你会不会正确洗手？正确洗手的7个步骤教你全面清洁手部远离细菌：

1. Get your hands wet.
把手弄湿
Turn the tap on and evenly rinse your hands in warm water. Contrary to popular belief, hot water does not remove bacteria more effectively than warm water, and may even increase the "irritant capacity" of some soaps.
打开水龙头，用温水均匀的冲洗手部，人们普遍认为热水比温水除菌的效果更好，但事实并非如此。而且热水还可能会增加某些肥皂的刺激性能力。
2. Use soap.
使用肥皂
Any type of soap will work, but if it helps you wash your hands more consistently to have soap that is a fun shape or color, or a pleasant fragrance, go for it.
什么肥皂都管用。但如果你对某种可爱造型、颜色或是芳香的肥皂有特殊情结，它会让你的洗手工作更能坚持下去，那就果断用起来吧。
3. Work up a lather.
打肥皂泡
Scrub on both sides of your hands, in between your fingers, and your wrists. Remember to wash around and under your fingernails.
擦洗手部两侧，手指之间和手腕都记得擦洗干净。记得全面清洗，指甲下面也别放过。
4. Wash your hands for about 15-20 seconds.
洗15-20秒
Be sure and rub your hands vigorously, and don't rinse off the soap right away. Give it time to do its job and give yourself time to get soap everywhere it should be.
一定要用力的摩擦双手，不要立即就把肥皂泡沫洗掉，你要花时间把肥皂泡沫均匀地擦满整个手部，这样才会发生作用。
5. Rinse your hands thoroughly.
彻底清洗手部
Place them under running water with your hands pointed downward but not touching the sink. This removes both the soap and the bacteria that was on your hands.
用流动的自来水冲洗手部，把手直接伸到水龙头下面，但注意不要碰到水槽。这样清洗才能去除掉手上的肥皂和细菌。

6. Use a towel to turn off the faucet, particularly in a public bathroom.
使用毛巾关掉水龙头，特别是在公用卫生间
If the faucet turns itself off on a spring or a photocell, let it. If not, use a paper towel, your elbow, or your forearm.
如果水龙头是通过弹簧或是光电管自行控制，那就不用管了。如果不是，请使用纸巾、肘部或是前臂来关掉水龙头。
7. Dry your hands with a clean towel.
使用干净的毛巾擦干手
Although they are not as good for the environment, paper towels are more sanitary for drying your hands than cloth towels. If you use cloth towels at home, launder them regularly. If you are in a public restroom, you can also use the hot air dryers if they are available.
虽然可能使用纸巾不环保，但是在擦干手的时候使用纸巾要比毛巾卫生得多。如果你在家的时候使用毛巾，请记得定期洗涤。如果是在公共卫生间，要是有热风烘干机的话你也可以使用。
