While I agree that most people don’t wash their hands correctly, I was recently surprised to learn that warm water doesn’t make much of a difference when it comes to killing germs.
Makes sense from the point of view of killing germs, and temperatures being tolerable for us also being tolerable for germs. My intuition is that it’s easier to get dirt (which contains germs) off hands with warmer water (similar to how it’s easier to wash dishes with warmer water).
