Having good personal hygiene and eating healthily is sometimes not enough to avoid getting sick. Here are five common household items that you should be sanitizing regularly to prevent illness. A 2012 study by the University of Arizona found that a mobile phone has more germs on it than a toilet seat. Because of this, it’s important to regularly sanitize your phone to avoid spreading germs onto your hands. Just like phones, many people use keyboards on their laptops or computers every day for work or school. Keyboards can get dirty very quickly, so it’s good to give them a clean about once a week. According to Chuck Gerba, a professor of environmental microbiology, germs last longer on surfaces than most people think. It’s important to disinfect light switches and doorknobs daily, as these surfaces are touched multiple times a day. Similar to phones and keyboards, TV remotes also get used a lot and can trap dirt easily. It’s important to clean all of your remotes regularly to avoid the spread of germs
