Temperature is one of the basic regulatory mechanisms of endotherms.

Temporarily heating the whole body or specifically targeted areas has frequently been employed as a therapeutic tool in the history of medicine and still shows considerable potential in the treatment of both chronic and malignant diseases.

It is most commonly used in combination with other therapies in order to improve treatment efficacy and response rates. In oncology, hyperthermia can act as a potent sensitizer especially for radiotherapy.

Both heckel and hydrosun are at the forefront in developing advances in technology and scientific research in this area of medicine, thus defining the use of hyperthermia for the potential benefit of patients.
