Dyson, who makes a new type of "airblade" hand dryer, funded research which showed regular hot-air hand dryers could make your hands "germier".
When volunteers kept their hands still, the dryers reduced skin bacteria numbers by around 37 per cent compared to just after washing. But the count rose by 18 per cent when volunteers rubbed their hands under one of the machines. Paper towels proved the most efficient, halving the bacterial count even though volunteers rubbed their hands. That's because the towels actually scrape off the bacteria.
