Not drying your hands thoroughly after washing them could increase the spread of bacteria and rubbing your hands whilst using a conventional electric hand dryer could be a contributing factor, new research has found.
The English study involved 14 volunteers and looked at 4 different methods of hand drying including paper towels, traditional hand dryers which rely on evaporation and a new model of hand dryer which strips water off the hands using air jets.
It found rubbing your hands together while using traditional hand dryers could counteract the reduction in bacteria following washing.
