Workouts are naturally sweaty ordeals if you’re doing them right. During your exercise routine, you’ll be sweating and touching all kinds of equipment. If you work out in a gym, all the equipment you use is being used by similarly sweaty people; even if wiped down in accordance with gym policies, workout facilities can be breeding grounds for microbial growth and the spread of potentially harmful strains of bacteria. Locker rooms provide an extension of the same problem. Fortunately, scientists and engineers are working on technologies that can serve as supplements for killing bacteria and keeping conditions less vulnerable to spreading bacteria.
