When you're grabbing lunch you might have your phone resting on the table. And when you go to the bathroom you might leave it on top of the toilet paper holder. Then, at the end of the day when you take the train or bus home, you exchange it from hand to hand as you pilot public transportation while still staying on top of all your notifications.
Let's face it: Your phone is a breeding ground for germs. And what is especially unhealthy about it is how close you put it to your face and mouth on a regular basis. Scientists at the University of Arizona found that your phone is ten times dirtier than most toilet seats. Wow, unbelievable! Another study also found that a typical high schooler's smart phone can have as many as 17, 000 bacterial gene copies on it. Think about that the next time you press your phone up against your face to make a phone call. Your phone is exposed to everything you touch. What's on your hands is on your phone. Health-care experts stress that washing your hands frequently with soap and water is the best defense against the spread of germs.
Everyone always remembers to wash their hands many a time a day, but many times ignore their phone screen. The reason why your phone holds so many germs is that it remains warm throughout the day because of how often we use it. The warm environment allows germ to grow very easily and puts you at a greater risk of getting infected.
The germs on our phones can also lead to the development of acne (粉刺) and blackheads on your face. When your phone is pressed against your face while you're on a call, the surface of our skin warms up, opening up our pore (毛孔). The germs then gets into your pores, causing skin irritation. Meanwhile, there are some other germs spreading items you're probably carrying right now.
