Your Apple Watch or Fitbit wristband is a hotspot for harmful bacteria linked to fever, diarrhea and a weakened immune system, according to a new study.
Researchers swabbed a range of wristbands, finding they are teeming with E. coli and Staphylococcus spp, which can lead to pneumonia.
The tainted bands were made from plastic, rubber, cloth, leather and metal.
The gym-goer showed the highest counts for bacteria linked to staph infections that can cause sepsis or even death, emphasizing sanitizing wristbands after working out.
However, the team found those made of gold and silver were the most sanitary.
'The quantity and taxonomy of bacteria we found on the wristbands show that there is a need for regular sanitation of these surfaces,' said the study's senior author Nwadiuto Esiobu, a professor of biological sciences at Florida Atlantic University.
Esiobu singled out active, gym-going healthcare workers as a group that might especially wish to take heed of the study's findings in an effort to avoid infecting at-risk patients.
