You’ve probably heard it a million times at this point, but in case you needed another reminder: Washing your hands is one of the most effective way to kill and prevent the spread of the coronavirus. You literally just have to get soap and wash your hands under running water for at least 20 seconds (here’s a list of songs you can sing to while doing so that isn’t “Happy Birthday”) to stay clean, and avoid touching your face.
But have you ever wondered how and why this is the case? Vox produced this awesome video that explains exactly how fighting viruses with handwashing works. In a nutshell, viruses are surrounded by a coating of proteins and fat (like oil!), and soap has two-sided molecules—one is attracted to water and the other is attracted to fat. When soap interacts with water and fat, it pulls apart the fat, demolishing the virus. It is important to note however, that this won’t happen immediately—you literally need to let soap do its job for at least 20 seconds. They also explain why washing your hands with just water isn't enough. Watch this video for a better explanation:
So yes, in case you needed another reminder, please wash your hands!
