Wash your hands properly after hand to prevent the spread of germs

It is often through the wash to inhibit the spread of germs, but many people tend to overlook the hands after washing and drying of steps so that the effects of SOAP.

United Kingdom of a new study shows, allowing the hand to dry out the correct way to prevent hands residues bacteria propagate to elsewhere.

United Kingdom Bradford University and other institutions of researchers in the new issue of the journal of applied microbiology, reported that on hand-washing is effectively remove bacteria, but also not all bacteria, if you subsequently do not seek to correct dry hands, the residue of bacteria can easily in moist environments continue to spread, so let the hand dry is also a very important step.

Due to keep hand hygiene's main purpose is to prevent the spread of bacteria from the hands to the holding of food and other items, the researchers designed a test to assess the hands dry out a variety of methods on the spread of germs.

The first call for volunteers touch raw meat with bacteria, then wash and take different ways to dry hands, in the process of every stage his hand in the dish on the press, then to detect how many bacteria can leave.

Results show that when using paper towels, cell phone with a variety of "dry" method, use paper towels to clean hands are the most effective, so let the hands become dry, through contact to the dish on bacteria declined the most.

The "stem cell" effect depends on how to use some of the "stem cell" warm air hand drying, rubbed his hands frequently asked to accelerate the evaporation of water, there are machines with high-speed water jet will blow dry.

The researchers found, and rubbed his hands in the process of washing hands is better than bacteria, in the drying process if the hand rubbed his hands, then the original hidden deep in the skin is not out of the surface with the hand of bacteria, so hand contact dish after drying, it will leave more bacteria.

But if you hand in the "stem cell" stationary, then hand after drying in the culture dish of bacteria and tissue difference is not too much.
