Whole-Body Hyperthermia (WBH): Enhancing Skin Repair, Ferritin Induction, and Preventing Surgical Site Infections

1. Molecular Mechanisms: WBH and the Induction of Ferritin for Skin Repair

Infrared Radiation (IR), a primary mode of heat delivery in *Whole-Body Hyperthermia (WBH) devices, has been shown to induce the protective protein *Ferritin* in tissue [1]. This induction has significant implications for *skin repair* and cellular protection. Ferritin acts as a potent *antioxidant*, helping cells manage oxidative stress, which is crucial during the recovery phase following tissue damage or in chronic wound environments.

Key Findings in Dermatology and Tissue Protection

• *Ferritin Induction:* Studies confirm that exposure to infrared radiation leads to the *induction of the putative protein ferritin* [1].
• *Skin Repair Implication:* Since ferritin acts as a cellular protectant, its induction suggests a mechanism by which IR-mediated WBH can *support and accelerate skin repair processes* and resilience against stress.
• *Chronic Wound Therapy:* wIR-A Hyperthermia has been explored as a novel therapy concept for *Ulcus Cruris* (venous leg ulcers) [2], indicating its beneficial effects on local microcirculation and healing in chronic, non-healing wounds.

2. WBH in Surgical Settings: Preventing Wound Infection

Using *systemic hyperthermia* (via *preoperative warming) is a critical intervention for reducing Surgical Site Infections (SSIs). A randomized controlled trial published in The Lancet demonstrated that *preoperative warming* significantly lowered the incidence of *wound infection* after clean surgery [3]. Maintaining normothermia or inducing mild hyperthermia supports immune function and improves wound perfusion, both essential factors for minimizing postoperative infection risk [4].

Evidence in Pathology and Post-Operative Care

• *Infection Rate Reduction:* The use of *preoperative warming* (a form of controlled WBH) is a proven strategy to minimize the risk of wound infection following surgery [3].
• *Systemic and Local Application:* Both local and systemic hyperthermia are beneficial in the surgical context [4]. The systemic effect of WBH optimizes the entire body’s capacity to fight infection and heal.
