Frequent use of headphones can lead to an increase in the number of bacteria in the ear canals, which can lead to a further increase in infectious diseases. In this respect reports BBC Science Focus cites research from scientists at Manipul University in India and the Naval Medical Research Institute in Bethesda, Maryland, US.
The first study found that headphones increased the population of different strains of Staphylococcus, a common skin bacteria in the ears. In the second case, scientists found that after wearing headphones for an hour, the number of bacteria on the headphones increased 11 times. The research was conducted on sterile headphones used by airlines on planes.
According to BBC Science Focus, there is no evidence that the increase in bacteria caused by wearing headphones is linked to the incidence of ear infections. However, some studies show that frequent removal of headphones can cause injuries to the ear skin. Through the resulting abrasions, bacteria can enter the body and cause infectious inflammation.
