Smartwatch Wristbands Hidden Bacteria – Potentially Harmful
A recent study conducted by researchers from Florida Atlantic University has uncovered some concerning findings about the cleanliness of smartwatch bands. The study, which tested 20 different smartwatch wristbands, revealed that a staggering 95 percent of them were contaminated with potentially harmful bacteria. These bacteria have the potential to cause various diseases. The researchers specifically looked for bacteria species such as Staphylococcus, Enterobacteria (similar to Escherichia coli), and Pseudomonas, which are known to cause infections in certain conditions.
What’s interesting is that the type of material used for the wristbands seemed to influence the amount of bacteria present. Rubber and plastic bands exhibited the most significant bacterial presence, whereas metal bands, particularly those composed of gold and silver, displayed a notably lower level of bacterial contamination.
According to biological scientist Nwadiuto Esiobu from Florida Atlantic University, plastic and rubber smartwatch wristbands create a more conducive environment for bacterial growth due to their porous and static surfaces, which tend to attract and harbor bacteria. While previous research has suggested that wristwatches and wearables could potentially serve as sources of infection in hospital settings, this study delves into how different materials can host opportunistic microbes
in our daily lives.The bacteria examined in this research are typically encountered in both human bodies and in various environmental settings. Under specific circumstances, these bacteria can potentially give rise to health issues such as abscesses, pneumonia, and salmonella infections. It’s worth noting that there were no noteworthy disparities in bacterial contamination observed between male and female participants. However, the activities engaged in by individuals did influence the findings. Notably, wristbands worn by individuals who frequent gyms exhibited the highest levels of staphylococcal bacteria. This study highlights a common oversight in our hygiene routines: we wear these devices all day, yet we rarely think about cleaning them.
Esiobu emphasizes the need for regular sanitation of these wristband surfaces, even if the bacterial numbers are relatively low. The presence of these pathogens still poses a public health concern. Particularly, these bacteria can be harmful to individuals with compromised immune systems, making it crucial for healthcare workers and others in hospital environments to regularly clean these surfaces.
The researchers also tested various cleaning substances to determine their effectiveness. Lysol-branded disinfectant spray and a 70 percent ethanol mix, often used in hospitals, were highly effective, killing 99.9 percent of bacteria within 30 seconds on all materials. Apple cider vinegar, a more natural option, was somewhat less potent against certain types of bacteria and required a longer exposure time.
To sum it up, this study acts as a valuable reminder of the significance of maintaining regular cleaning routines for our wearable devices. It’s not limited to just smartwatch bands; we should also take into account other gadgets that regularly make contact with our skin, like earbuds and cell phones. By maintaining good hygiene practices with our tech gadgets, we can reduce the risk of potential bacterial transmission and infection.
