Headphones wear 1 hour bacteria to multiply 5 times

Recently, Mr. Zhao, a citizen of Nanchang, called this newspaper and said that the earphones on the Internet are hotbeds of bacteria. Once the headphones are put on, the air in the ears is difficult to circulate, and the temperature also rises. The bacteria on the surface of the earplugs will rapidly multiply, which is not conducive to the ears. health. Mr. Zhao wants to know if this rumor is true? To this end, our reporter conducted some experiments.
Most citizens never clean headphones
Before conducting the experiment, the reporter conducted a random interview with the citizens on the streets of Nanchang. Ms. Li told reporters that she likes to listen to music with headphones. The frequency of using headphones is also very high, but she has never cleaned the headphones. "Is there not a lot of bacteria?"
Mr. Zhang also said that he had never cleaned the earplugs. "The earplugs are used by themselves. It should not be too dirty, so I don't think it is necessary." However, Mr. Zhang also raised the question: "If I want to clean up, how should I? Can it be cleaned up? Is it a special disinfectant with water?"
Similar questions existed among the majority of the citizens interviewed by the reporter. Only a few citizens said that if they see something dirty on the headphones, they will wipe them with paper towels or wipes, but there is no customary cleaning.
In-ear headphones are more susceptible to bacteria than earbuds
Experimental props: three pairs of used headphones, single ear ear type is No. 1, double ear in ear type is No. 2, and binaural ear ear type is No. 3.
Experimental tools: sterile saline, sterile straws, sterile culture dishes, medical sterilization swabs, etc.
Laboratory personnel: Yingyan, Department of Clinical Control, Xihu District, Nanchang City (Note: The results of this experiment are only responsible for this experiment
In-ear headphones can enter the external auditory canal
The reporter sent Mr. Zhao's three pairs of earphones to the Clinical Control Division of the West Lake District CDC. Two pairs of earphones were used when they were used on the inner ear and did not penetrate into the external auditory canal. The other in-ear headphones could be directly inserted. The external auditory canal is in contact with the skin on the ear canal. Which kind of earphones hide more bacteria? The mouth said nothing, the experiment is evidence.
The experimenter Ying Yan first disinfected the No. 1 earphone, then smeared the earphone with a cotton swab, then put the cotton swab into the test tube, inject 10 ml of 0.9% sterile physiological saline into the test tube, and oscillate. This allows the bacteria on the cotton swab to be uniformly mixed in the physiological saline. Thereafter, the experimenter took 1 ml of the solution from the test tube, poured it onto a sterile plate, and then added the medium.
For the No. 2 and No. 3 headphones, before the experiment began, the experimenter wore the left ear of both pairs of headphones for one hour, and the right ear remained as it was. After that, the experimenter also sampled the No. 2 and No. 3 headphones. After all the three earphones were sampled, the experimenter placed the five plates into a 36 ° C incubator for bacterial culture.
Wearing 1 hour of bacterial reproduction nearly 5 times
After 48 hours of training, the reporter saw that 4 of the 5 plates had only white spots. The experimenter explained that this is the colony formed after 48 hours of cultivation, and how many white spots there are. The reporter found that the only thing that had no white spots was the sampling on the headphones after disinfection.
After that, through the calculation of the experimenter, it was found that the No. 1 earphone was aseptically dropped; the left ear of the No. 2 earphone was a sample after one hour of wearing, the colony was 120, the right ear was a non-treated earphone, and the colony was 25; and the left ear of the No. 3 earphone was also After wearing the sample for 1 hour, there were 25 colonies, and the number of untreated right ear colonies was 9. Thus, in-ear headphones are more susceptible to bacteria than earbuds. After one hour of wearing the in-ear headphones, the bacteria multiplied nearly five times before; while the earbuds were worn for an hour, the bacteria multiplied nearly three times.
The experimenter Ying Yan said that the bacteria are generally vegetatively propagated by a simple two-splitting method, and the splitting time is generally 20 to 30 minutes. Therefore, from this point of view, wearing an hour of headphones, bacteria can multiply up to five times, if it does not wash all year round, it will accelerate bacterial growth.
Headphones don’t clean up for a long time, be careful
The person in charge of the laboratory of the West Lake District CDC said that the earphones will stick to many bacteria without cleaning for a long time. Don't underestimate these bacteria. Although everyone always feels that cleaning the headphones for a long time does not affect the body, it is different from person to person. of. When the body's resistance is good, they don't make people sick. If an individual's resistance declines, they will make people sick. Therefore, for your own health, you should regularly clean and disinfect the personal items such as headphones; and your own headphones are for your own use, do not use them for others, so as to avoid generating more bacteria.
As for the cleaning method, the person in charge said that the public can use a better quality wipe to disinfect, or use a cotton swab with alcohol to wipe, according to the quality of the earphones to choose the disinfection method.
