How often should you wash your towels? No, really

Do not read on if you are eating your breakfast. Especially if you are tucking into your toast in bed. Earlier this summer, an American study found that after just one week of use, your pillowcase can harbour more bacteria than the average toilet seat. Meanwhile, a survey this month suggested that a third of us wash our bathroom towels just once every three months, while nearly two million people in the UK do so only once a year.
