For many of us, it's the first thing we touch when we wake up and the last thing you see before you go to bed, but your cell phone is also one of the germiest surfaces you touch all day.
It used to be door handles, bathroom sinks and keyboards that we made sure to protect against during flu season, but your constant companion is also a prime carrier of bacteria.
A new study from the Wall Street Journal finds "abnormally high numbers of coliforms," a bacteria that can mean fecal contamination, could be all over your phone, making it in some cases, as dirty as a toilet seat.
The report says of the phones they tested, about 2,700 to 4,200 units of bacteria were found on each one, comparing that to drinking water, which is supposed to have less than one unit per half cup.
Washing your hands often and cleaning your phone are a few of the ways to help keep the bacteria at bay, but you should check your phone's handbook first to see what kind of products are safe for the screen.
The Mesa County Health Department said you should avoid touching your mouth nose or eyes after touching surfaces such as cell phones, door knobs and keyboards.
According to some health experts, bacteria on your phone could cause pinkeye or diarrhea.
