Dr Manal Mohammed, Lecturer in Microbiology, was interviewed by the Mail Online about how sharing personal items can lead to unforeseen unhygienic consequences.
Research has shown that the sharing of personal items can facilitate the spread of bacteria, viruses and fungi.
Dr Mohammed gave a couple of examples of the most contaminated personal items which should not be shared, including earphones, towels, lipsticks, toothpaste, razors and even food.
Dr Mohammed added: “Before sharing food, ask yourself: ‘Would I share this person’s saliva? ’ When we eat, droplets of our saliva transfer to the food, as well as our cutlery. It’ll also be on our hands, which we will then use to touch surfaces.”
