Does the water temperature matter when it comes to washing our hands?
Nope! In fact, a lot of us associate hot water with making things sterile, but a new study says it’s no more effective at killing germs on our hands than cool water. In fact, as long as we’re combining water with soap, researchers say cool water may be better for most people. That’s because the contaminants in home water pipes, that can cause skin irritations, dissolve more easily in hot water. So, go ahead and wash your hands in cool water. It’ll work just as well.
