You don't always need to wash your hands in warm water, but it can be a good idea. I have two sons; a three year old and a four year old. The only time my wife and I have them use warm water is when we are sitting down to eat. Otherwise, cold pretty much does the trick. We usually go into the bathroom and turn the hot water on. While the water is warming up we will call the boys in, they stand and wait while mommy or daddy gets the water ready by turning the hot down and cold up to get a warm mix. We also try to mix the water at a fairly low water pressure, so as not to splash and create a mini water park. Generally for adults when preparing food, the warmest you can stand it is recommended. That's not to say ';as hot as possible';; you don't want to hurt yourself. For little ones, though I think it's best to go longer on the soap and not hurt them at all. Children are much more sensitive in their little nerve-endings, so what's warm to you may be unbearable to them. Twenty seconds of rubbing with soap will kill the vast majority of germs. And that's the one I emphasize with my boys.Do you need hot water for hand washing? If you do have hot water, what are the temperature specifications?
