The invention relates to a biomedical device comprising computing means, immersion means for dipping a patient in a virtual intelligent environment, an interface for controlling the computing means, operating the immersion means and for collecting results of related medical means and different means for obtaining said results. The inventive device is characterized in that the computing means are used for controlling the immersion means in such a way that virtual three-dimensional therapeutic environments comprising a virtual person in the form of the patient, a closed three-dimensional envelop emitting at a determined light frequency which envelops the person and any scenery in which the virtual person and the closed radiating envelop thereof are located for receiving a determined psycho-neuro-immunologic response, which is positive for the organism, are formed. In particular the inventive method consists in progressively increasing the light frequency of the closed envelop and of the person receiving said radiation.
