Bioresonance is most simply explained by using an example from nature. Surely, the oldest kind of biological resonance is our sunlight. If the sunlight touches our skin, it turns brown. This is, however, not caused by the skin warming up; otherwise we would also gain a bronzed skin tone by simply visiting the sauna. The reason for the tanning effect lies in the ultraviolet rays, which are part of the sunlight Ultraviolet light with a wave length of 10-400 nm, is able to stimulate pigmentation of the skin, a regulation system integrated in our skin, which starts pigmentation when exposed exactly to this frequency of sunlight, causing it to appear tanned. Pigmentation of the skin is only one of the regulations prompted by the sunlight, another one is the stimulation of vitamin D production.
It is not hard to understand, that there are other frequencies beside this narrow frequency band of the sunlight, which also trigger off their own regulations. Way back in the year of 1976, it was Paul Schmidt, who realized the connection between the application of a frequency and its regulation properties towards the organisms of humans, animals and plants. With this, he founded the exogenous (affecting from the outside) bioresonance. In these correlations, let me also mention the endogenous Bioresonance, which works with the body's own oscillation patterns. Today, the Bioresonance according to Paul Schmidt works exogenously as well as endogenously, the exogenous Bioresonance, however, still plays the overriding part.
