At the neck level immersion, the water pressure causes significant displacement of blood from the lower limbs to the Intrathoracic circulation, triggering adaptive physiological responses due to the increase in central blood volume and consequent cardiovascular burdens. Immersion in warm water breaks the homeostasis, stimulates regulation mechanisms and responses of organs and systems beneficial to healthy and heart failure individuals. In literature there are a growing number of studies demonstrating the efficacy of exercises performed in the water.
