Cell phones are an essential part of our daily lives and are used constantly throughout the day. However, this constant use also means that they can harbor a significant amount of dirt and bacteria, making them potentially harmful to our health.
One of the main reasons why cell phones can be dirty is because we touch them with our hands, which can carry a wide range of bacteria and other microorganisms. When we touch a surface such as a doorknob, our hands can pick up germs, and if we then touch our cell phone, we transfer those germs onto its surface. In addition, our hands produce oils and sweat, which can accumulate on the surface of the phone and provide a breeding ground for bacteria.
A study published in the Journal of Applied Microbiology found that the average cell phone can have up to 25,000 germs per square inch. In comparison, a toilet seat has around 1,200 germs per square inch. The study found that the most common type of bacteria found on cell phones were Staphylococcus aureus, which is known to cause infections in humans.
Another study conducted by the University of Arizona found that cell phones can be up to 10 times dirtier than a toilet seat. The study also found that the dirtiest part of the phone was often the touch screen, as it is the part of the phone that is touched most frequently.
To reduce the amount of dirt and bacteria on your cell phone, it’s important to regularly clean it with a micro-fibre cloth and a cleaning solution. You should also avoid using your phone in places where it is likely to come into contact with germs, such as in public restrooms or on public transportation. Washing your hands regularly and avoiding touching your face can also help reduce the spread of germs.
