Description

Summary

Whole-body hyperthermia (WBH) to an internal temperature of 38.5 C (101.3 F) using an infrared heating device has been associated with significant reductions in clinical depression. This prior work utilized a WBH medical device that is manufactured in Germany, is not FDA approved, and is not widely available. The goal of this initial pilot project is to ascertain whether an infrared sauna, the Curvey Sauna Dome, which is readily accessible (i.e., can be purchased by consumers in the US) can be used to conduct WBH that achieves an internal body temperature of of 101.3 F in healthy volunteers.

Prior work has demonstrated that whole body hyperthermia (WBH) to an internal temperature of 38.5 C (101.3 F) using an infrared heating device is associated with significant reductions in clinical depression. This prior work utilized a Heckel WBH device, a medical device manufactured in Germany that is not FDA-approved and that is not widely available. The goal of this pilot project is to ascertain whether the Curve Sauna Dome, an infrared sauna that is readily accessible (i.e., can be purchased by consumers in the US) can be used to conduct WBH that achieves an internal body temperature of of 38.5 C (101.3 F) in healthy volunteers.

  • Current use of hormone-based birth control, such as IUD or oral contraceptive
  • Needing to use of any medication that might impact thermoregulatory capacity within 5 days of the sauna session, including: stimulants, diuretics, barbiturates, beta-blockers, antipsychotic agents, anti-cholinergic agents or chronic use of antihistamines, aspirin (other than low-dose aspirin for prophylactic purposes), non-steroidal anti-inflammatory drugs (NSAIDs), systemic corticosteroids, cytokine antagonists
