Body temperature plays a crucial role in the regulation of the immune system.

A healthy organism reacts to the threat of illness with regulated increases in temperature, progressing in acute cases to a high fever which can trigger an enhanced immune response.

Similarly, an artificially induced increase in body temperature can result in a sustained stimulation of otherwise inhibited powers of self-healing. 



An important feature of water-filtered infrared-A (wIRA) is its ability to penetrate into deeper-lying tissues while at the same time being gentle to the skin, thus allowing the application of wIRA at higher intensities resulting in increased effectiveness. The rise in the body‘s core temperature is correspondingly rapid and well-tolerated. In the leg and foot regions, further infrared emitters create a comfortable temperature in the interior of the tent so that the minimising heat loss.

The three levels of whole-body hyperthermia (WBH)

  • Subclinical, mild WBH: 37,5-38,5°C
  • Moderate WBH: 38,5-40,5°C
  • Extreme WBH: 40,5 - 42°C

Example moderate whole-body hyperthermia "short-duration": 95 min. at 39°C:


Example moderate whole-body hyperthermia "long-duration": 300 min. above 39°C:

Whole-body hyperthermia at higher temperature levels requires continuous vital functions monitoring. Body core temperature, pulse rate, ECG, oximetry, blood pressure (non-invasive measurement) and breathing rate are measured continuously and monitored with the aid of a color display and adjustable alarm limits. Vital function data readings are stored using the LAN-compatible customised hyperthermia software FebroData®, which incorporates numerous other functions supporting treatment and data evaluation:

  • The temperature course is saved and analysed (irradiation and treatment duration, gradient of the rise in temperature, integral over the designated base temperature)
  • Various temperature curves can be superimposed and compared for any given patient
  • The accompanying medication can be recalled directly from self-administered lists and marked on the time axis
  • A full-year calendar is created for each patient, allowing a rapid overview of a patient’s previous hyperthermia sessions, along with other treatments
  • Statistical functions allow a direct overview of the patient cohort treated in terms of gender, age, indications, number of treatment sessions and temperature levels
  • Up to 4 parallel treatment sessions can be monitored on a single PC screen

The whole body hyperthermia treatment consists of two phases

Irradiation phase

Heat retention phase

The patient lies recumbent with his/her head positioned either inside or outside the tent. The wIRA irradiators are arranged above the exposed upper part of the body. The patient lies on the comfortable mattress of an adjustable hospital bed. The patient lies wrapped in the walls of the tent. The temperature generally still increases by a few tenths of a degree and can be maintained at this plateau level for as long as required. The electrically adjustable treatment bed allows the patient’s position to be altered according to his/her wishes and needs – from a horizontal position with the patient lying on the back or side to an upright seated position. In this way, comfortable positioning can be ensured even during a treatment lasting several hours. Using the electrically powered heckel-Lift 3000, the irradiator can be raised high above the bed improving the patient comfort.
