How to Wash Your Hands Properly

posted by Jason Kottke   Mar 13, 2020

Most humans have been washing their hands since childhood, but I bet very few of us have been doing it correctly. Because of the effectiveness of hand-washing with soap in preventing the spread of COVID-19, the CDC and the WHO (and health professionals everywhere) both make it their top recommendation and provide guidance on how to do it properly: CDC hand-washing instructions, WHO hand-washing instructions.

Lather your hands by rubbing them together with the soap. Be sure to lather the backs of your hands, between your fingers, and under your nails. Scrub your hands for at least 20 seconds. Need a timer? Hum the “Happy Birthday” song from beginning to end twice.

Here’s a video from the WHO on proper hand-washing technique (and a similar one from Johns Hopkins that has subtitles):

And a graphic from the WHO:

And if you’re getting sick of singing Happy Birthday while washing your hands, a site called Wash Your Lyrics can help you make a hand-washing infographic with your favorite song’s lyrics.
