Is it better to wash your hands with hot water, warm water or cold water?  According to a report, water temperature really doesn't matter!  Researchers at Rutgers University found that cool water is just as effective at removing bacteria in handwashing as hot water. The study tested the effectiveness of bacteria removal on participant’s hands and three different water temperatures, 60 degrees, 79 degrees and 100 degrees, using different volumes of soap over a six month period. What they found is the temperature and amount of soap had little difference of riding your hands of germs.  One thing that seemed to defiantly work well is to wash your hands for at least 10 seconds.
