Whole-Body Hyperthermia (WBH) in Psychiatry

Abstract

AbstractNew effective therapies for managing and treating psychiatric disorders such as major depression are urgently needed. Mood-enhancing effects have repeatedly been observed after whole-body hyperthermia (WBH) treatment in other medical disciplines, and there is promising evidence that WBH may be used in psychiatry for patients suffering from depressive disorders. Most importantly, a recent study demonstrated a significant, rapid, and partially lasting reduction of depressive symptoms in patients with major depressive disorder following a single session of water-filtered infrared-A induced whole-body hyperthermia (wIRA-WBH). Underlying mechanisms of actions may include immune modulation and serotonergic neurotransmission via warm-sensitive afferent thermosensory pathways to the midbrain.Current studies are focused on verifying these earlier findings and clarifying the mechanisms involved. Herein, we report on the establishment of WBH methodology in the psychiatry setting and provide our opinions on necessary future research.
