What would happen if you touch gym equipment and put your fingers in your mouth afterward? I usually shower or wash my hands after going to the gym. But if you touch something there and put your hand or fingers in your mouth, are the germs on the gym equipment contagious or can they make you sick?
Bacteria and viruses exist everywhere -- not just on gym equipment. We are only aware of the possibility of germs being present because people sweat during workouts. Yet, because of the moisture, more germs are able to survive for a longer period of time that on other surfaces -- hundreds of times more [Examining Gym Cleanliness]. And, yes, these germs can be contagious.
Regardless of where you are, you should always wash your hands prior to putting them in your mouth or before using them to eat food.
