A study carried out by researchers at Florida Atlantic University reveals that watch straps, including those of smartwatches and fitness trackers, can be veritable hotbeds of bacteria, some of which can be harmful to the body. Fortunately, there are simple ways to keep them clean.
The overwhelming majority of wristbands analysed in the research (95%) were found to be contaminated, with rubber and plastic straps showing higher bacterial counts. This can be explained by the fact that porous, static surfaces tend to attract bacteria and allow them to grow. Gold and silver surfaces, on the other hand, showed little bacterial activity. There were no significant differences between watches worn by men and those worn by women.
What's most worrying is that many dangerous bacteria were found in this study, such as Staphylococci and even E. coli, which can cause serious illness in some cases. Another finding was that the highest levels of Staphylococci were found on wristbands worn while exercising, underlining the need for regular disinfection after workouts, especially when exercising indoors, in contact with other people.
As for the best way of eradicating these bacteria, the researchers recommend the use of a disinfectant spray (Lysol) or 70% ethanol, which are highly effective regardless of the wristband's material. These solutions can eliminate 99.99% of these bacteria in just 30 seconds. Alcohol wipes and apple cider vinegar are also effective, but require longer contact times for effective results.
The results of this study are published in the journal Advances in Infectious Diseases. – AFP Relaxnews
