Previous studies on hyperthermia-based protocols for detoxification have been methodologically challenged and are not readily reproducible. Furthermore, there are no studies in the literature that identify how long of a protocol is tolerated, is feasible in the general population, or how long is needed to observe PCB (or other pollutant reduction). Therefore, we will employ a "high-dose" protocol and a "low-dose" protocol, based on ranges reported in the literature, in order to evaluate dose-finding outcomes to hyperthermia, including tolerability, retention, and participant-reported outcomes.
