In addition to impacting depressive symptoms and body temperature, The investigators have observed that WBH induces striking increases in prosocial and self-disclosing behavior in many individuals. This effect initiates in the heating phase of the treatment and culminates at maximum body temperature. Importantly, our observations thus far suggest that this prosociality only occurs when the person in the hyperthermia box is accompanied by someone he/she knows to at least some degree. For example, a recent subject was silent during his initial WBH treatment in which he was attended by one of our staff that he had never met. He elected to get a repeat WBH session. The same "attendant" was present for this second WBH session, and during this session the patient became strikingly talkative and without prompting self-disclosed a range of very intimate personal issues related to his depression, such as a previously undisclosed history of childhood sexual abuse.
