Recent research has shed light on the unsuspecting breeding grounds for harmful bacteria—Apple Watch and Fitbit wristbands. A study conducted by researchers from Florida Atlantic University (FAU) has revealed that these popular wearable devices can harbor harmful bacteria associated with ailments such as fever, diarrhea, and a weakened immune system.
Published in the science journal Advances in Infectious Diseases, the study conducted by the US-based FAU aimed to uncover the presence of harmful bacteria on various wristband materials and their potential correlation with bacterial build-up.
The study analyzed wristbands made from different materials, including plastic, rubber, cloth, leather, and metal (gold and silver). The researchers discovered that a staggering 95 percent of the wristbands tested were contaminated with potentially harmful bacteria.
The study revealed the following concerning findings:
- 85 percent of the wristbands contained Staphylococcus spp: This bacterium is known to cause staph infections.
- 60 percent of the wristbands had E. coli bacteria: Escherichia coli is associated with various gastrointestinal issues.
- 30 percent of the wristbands harbored potentially lethal Pseudomonas spp: Pseudomonas bacteria can lead to severe infections.
Notably, individuals who frequented gyms exhibited higher bacterial counts, particularly for staph infections. This highlights the importance of sanitizing wristbands after engaging in physical activity.
Interestingly, the study also found that the material texture of the wristbands played a significant role in bacterial growth. Plastic and rubber wristbands demonstrated higher bacteria counts, while metal wristbands, particularly those made of gold and silver, exhibited minimal or no bacterial presence.
The researchers attributed the heightened bacterial growth on plastic and rubber wristbands to their porous and static surfaces, which foster an ideal environment for germs to thrive.
Nwadiuto Esiobu, PhD, senior author of the study, emphasized the need for regular sanitation of these wearable surfaces. Even in small quantities, the presence of these pathogens holds public health significance.
Furthermore, the study underscores the need for increased awareness, especially among healthcare workers who frequent gyms. Proper sanitization of wearable devices is crucial to prevent potential infections and the transmission of harmful bacteria to vulnerable patients.
As the popularity of wearable devices continues to grow, individuals are advised to prioritize regular cleaning and sanitization to mitigate the risk of bacterial contamination.
