When you gotta go, you gotta go, and sometimes that means you have to use a public restroom that might be less than clean. Some people plop their behind down on the toilet seat, and others choose to hover over it– so which option protects you from germs more? Primrose Freestone is a senior lecturer in Clinical Microbiology at the University of Leicester, and says there’s really no need to squat over the bowl. First, your chance of developing an infection from your bottom sitting on a toilet seat is slim to none due to bacteria and yeast that protects your skin, and also the fact that most intestinal diseases involve hand-to-mouth transfer of bacteria. Women’s physical health therapist Brianne Grogan says squatting over the bowl may actually cause injury or increase the risk of infection as it could lead to incomplete emptying of the bladder. The experts say the key to complete protection from toilet-associated germs lies in washing your hands correctly after you go. In case you need a refresher– that means 20 to 30 seconds of washing the hands, fingers, and underneath fingernails with warm, soapy water.
