When's the last time you cleaned your smartwatch band? It's probably been a while, right? Here's why scientists want you to change that.
As smartphones became mainstream over the past decade, multiple research papers popped up, documenting how extremely filthy they can get. Fresh research from the University of Arizona said that smartphones can be 10 times dirtier than a toilet seat. Another paper published in Nature claimed that microbial infection is so bad that robust public health and biosecurity protocols are needed to minimize the risks.
As part of the test, the team painstakingly analyzed bands made out of rubber, plastic, fabrics, leather, and metal worn by people across different professions such as firefighting, desk jobs, driving, and the veterinary field. Another strain discovered during the test, s. aureus, can trigger blood clotting, infective endocarditis, and fatal organ failure. Overall, the highest concentration of Staphylococcus-class bacteria was found on plastic bands, followed by fabric, rubber, and leather bands. In general, metal bands, such as those with silver and gold components, “had little to no bacteria.”
“Metals inhibit the enzymes on the membranes of bacteria … . So most persisting bacteria will die over time,” Esiobu explains regarding the safety offered by metallic surfaces. “So most persisting bacteria will die over time. “ The bands that Samsung and Apple sell for their smartwatches are made out of leather, fluoroelastomer, stainless steel, silicone, thermoplastic, polyurethane, woven nylon, polyester yarn, and fluorocarbon rubber. Depending on the strap material, you might have to accordingly adjust the type of cleaning fluid to get the best results while also avoiding any damage.
