This is essentially a mineral water treatment. Hot or cold water, rich in minerals such as silica, sulphur, selenium and radium, is used. Massages through moving water also form an essential part of this therapy. Although modern technology enables one to benefit from balneotherapy in a controlled environment, it is traditionally done outdoors. Since this therapy helps in reducing swelling as well as stiffness of muscles, it is also wellsuited for arthritis patients.
