There is more to know about hand hygiene than you would think. First, poor hand hygiene is the number one cause of the spread of infectious disease in a hospital system. When you wash your hand you should not skimp on the soap, nor the time. To prevent chapping or side effects form lots of washing you should pat your hands dry over rubbing them dry. Also after washing your hands you should turn the water off with a towel rather than touch the handle and get your hands dirty again. Rings are not recommended while working. They have sharp edges which can cause injury. Germs seem to gather under a ring. And finally those who wear a ring have a tendency to wash their hands less often.
