[Thalassotherapy effect on cardiovascular system and cardiac rhythm variability].

A complex study of physiological parameters allowed us to analyse reactions of cardiovascular system to dipping into a hot water varying in salt concentrations. These reactions differ from those to dipping into cold water. Dipping into hot water leads to depression of the tonicity of parasympathic nervous system in such a manner that increased heart rate does not cause vascular contraction. Effects of water salt concentrations on the above parameters need further investigations.
