A recent study by Charles E. Schmidt College of Science, Florida Atlantic University, United States A highly unknown fact was determined about one of the most commonly used objects by humans: watch.
The agency conducted an investigation to determine the contamination Material The tapes of these artifacts were made from these items and lead to surprising conclusions.

How do researchers think this study was conducted?
According to information released by the university, different tests were conducted using seat belts. Plastic, rubber, fabric, leather and metal (gold and silver) to verify whether there is a correlation between the material of the bracelet and presence of bacteria.
At this point, researchers are trying to determine the hygienic status of this bracelet and what is the best way to properly disinfect it.
Bacterial susceptibility studies attempted to verify the effectiveness of three disinfectants: Lysol disinfectant spray; 70% ethanol Percentage, often used in Hospital and alcohol wipes; There is also a more natural solution made from apple cider vinegar.
What results were collected?
The researchers concluded that plastic and rubber bracelets widely used in smart watch straps are the most polluting.
These trials showed higher bacterial counts than before metal braceletEspecially gold and silver ones, there are almost no bacteria.
The reasons have been found in the texture of the wristband material and the subject’s activity (hygiene) at the time of sampling.
The lead author of the study, Nwadiuto Esiobrevealed that “Plastic and rubber bracelets may provide a more suitable environment for bacterial growth, as porous and static surfaces tend to attract and colonize bacteria.”
What type of bacteria were found?
Scientists involved in the study discovered that both substances are present staphylococcus and Pseudomonas – 85% and 30% respectively present in the bracelet – and gut microbial genus Escherichiaspecifically E. coli (present in 60% of bracelets).
Type 1 bacteria cause a variety of clinical illnesses and are commonly found in the armpits, nose, and groin.
In the case of Pseudomonas bacteria that are commonly found in the environment, they can cause a variety of infections in the blood, lungs (pneumonia), and/or various parts of the body after surgery.
Regarding disinfectant, if Lysol and 70% ethanolin eliminating 99.9 Bacteria In less than 30 seconds.
Although apple cider vinegar does not have the same potency and requires more complete exposure ( about two minutes) to reduce bacterial counts.
