Science showsplastic materials can release VOCs, microplastics, and phthalates, especially when exposed to heat. Exercise equipment used in heated environments (saunas, hot yoga studios) may increase this chemical exposure.
Laurel recommends exercise equipment that is relatively plastic-free, especially for anything used in a sauna or heated environment.
Laurel avoids exercise equipment with significant plastic components that will be in prolonged contact with sweaty skin or used in heated settings.
Tip: Focus your swap efforts on items you grip or press against your skin during heated exercise -- like resistance bands and foam rollers.
