The strength of the local mountain springs lies in its molecular structure, which literally makes it "living water". In general, water molecules group together into so-called clusters, and these clusters give it, to put it simply, a kind of "memory" ability. Favorable influences of the surroundings bring water to life (its molecules form more complex clusters) while unfavorable ones "kill" it (the clusters fall apart). According to research by the Liechtenstein laboratory Hado Life Europe, springs around the spa show a high level of "liveliness". The "liveliest" is the relatively little known and remote Finnish spring. On the contrary, Priessnitz, Bezruč, Večerní and Jitřní Springs are characterized by their weak, health-beneficial radioactivity.
