Is hot water better than cold water for washing hands?

This popular wisdom seems to say that hot water is better...

Most of the value of hand washing is the physical rubbing and rinsing process that dislodges bacteria from the surface of the skin. A study at Rutgers University in the US found that hot water was no better than cold. In fact, uncomfortably hot water increases the bacterial load, as it destroys your skin's natural protective barrier.
