C
Your ears are already dark, wet and full of oils and dead skin—a delicious meal for many bacteria (细菌). It seems that wearing headphones could only make that environment more inviting to these bacteria.
Actually, a 2008 study at Manipal University in India found that frequent (频繁的) use of headphones did increase the population of bacteria in the ear—mostly the staphylococcus, a common skin bacterium. And in 1992, a study at the Navy Medical Research Institute in Bethesda, Maryland in the US, found that the kind of over-the-ear headphones used by airlines had 11 times more bacteria after having been worn for just one hour.
As unpleasant as this sounds, there is no need to worry about it. The headphones in the second study were clean before use, so began with a very low bacterial population and that increase resulted in a fairly low number in absolute terms.
Also, this increase was not fast enough to increase the reproduction of bacteria. The study’s authors said that most of the bacteria must already have been present in the deeper skins. The dark warm conditions while wearing headphones just encouraged some of them to come out and play. Furthermore, there are no signs that these bacteria can cause any harm. A 2002 study of call centre workers in Malaysia found no connections between headphone use and the illness in the ear.
The bacteria that increase in your ear while you listen to music are the ones that live there normally, and your ear is able to deal with them. However, several studies have suggested that repeatedly putting on and taking off headphones may increase the risk of skin abrasions (擦伤) that allow harmful bacteria to get in and cause illnesses.
