"Mineral water is known for its high content of carbon dioxide that penetrates the skin during a bath and acts as a direct vasodilator in the body meaning that it dilates blood vessels and improves their elasticity. This contributes mainly to the lowering and improved stabilisation of blood pressure, and also relieves the heart muscle. Mineral water also dilates capillaries in the skin, which turns reddish in the bath, while vessels in the depths of the body also dilate reflexively, all of which improves blood flow. As peripheral resistance is thus decreased, the heart does not need to work as hard. Organs thus receive more oxygen and other required substances while the organism disposes of waste more quickly and abundantly on account of improved circulation. The functioning of organs improves while the entire body is strengthened, it regenerates faster and its immunity to diseases improves."
