Whole-Body Hyperthermia (WBH)
Whole-body hyperthermia elevates core body temperature to 39–42°C using infrared cabins, water blankets, or radiant heat devices — mimicking but controlling a therapeutic fever. Cancer cells are more sensitive to heat than normal cells due to their abnormal vasculature (limited heat dissipation), reduced heat shock protein production, and altered metabolism. WBH is used in European oncology clinics (especially Germany) combined with chemotherapy to increase drug penetration and enhance immune response.
Mechanism of Action
Raising core temperature to 39–42°C directly damages cancer cell DNA, denatures proteins critical to cancer cell survival, improves tumour blood flow (paradoxically — improving drug delivery), increases cancer cell membrane permeability to drugs, and activates heat shock protein-dependent immune responses. At 42°C+ (clinical hyperthermia), direct cancer cell death occurs selectively due to tumour vasculature's inability to dissipate heat.
Cancer Types Studied
Protocols & Dosing
Regional / Local Hyperthermia (Oncothermia)
Capacitive hyperthermia device targets specific tumour area to 40–44°C for 60–90 min, 2x weekly alongside radiotherapy. Well-evidenced especially for cervical, bladder, and soft-tissue tumours. Available at German/Italian clinics.
Mild Whole-Body Hyperthermia (39–40°C)
Infrared cabin or water immersion to 39–40°C core temperature for 60–120 min. Available at hyperthermia clinics. 1–2x weekly. Combines immune activation with psychological benefits.

Cautions & Contraindications
- Cardiovascular monitoring required — hyperthermia increases heart rate and blood pressure
- Contraindicated in heart disease, severe hypertension, pacemaker
- Requires experienced clinical team — hyperthermia exceeding 42°C can damage normal tissue
- Ensure adequate hydration before, during, and after
- Contraindicated in active infection or dehydration
