The number of sick days taken by office workers could be reduced if companies implemented a better cleaning routine and staff improved their personal hygiene, finds a new academic study. The workplace is ranked as one of the unhealthiest places you’re likely to inhabit on a daily basis, says Dr Lisa Ackerley, hygiene expert and visiting professor at the University of Salford, whose study revealed that the main cause of germs at the desk and keyboard is poor personal hygiene, with nearly 50 percent of office workers responding to her survey admitting they do not wash their hands after going to the toilet. Your hands and the surfaces you touch, including your office chair are germ motorways, she warns. Crumbs and spills encourage the growth of bacteria that can lead to stomach bugs, coughs, flu and even food poisoning. Bacteria and viruses that people bring back from the toilet multiply on the hard work surfaces of the desk and chair and remain infectious for 24 hours.
