This bath can be given from 15 to 60 minutes at a temperature ranging from 260C to 280C. It can be given for long duration, without any ill-effects, as the water temperature is akin to the body temperature. The neutral bath diminishes the pulse rate without modifying respiration.

This treatment is the best sedative. Since the neutral bath excites activity of both the skin and the kidneys, it is recommended in cases relating to these organs. It is also beneficial for cases of organic diseases of the brain and spinal cord, including chronic inflammatory conditions such as meningitis, rheumatism and arthritis.

A neutral immersion bath taken for 30 to 60 minutes is highly beneficial in general dropsy, due to cardiac or renal diseases. It also helps those suffering from multiple neuritis, alcoholism and other narcotic habits, chronic diarrhoea, peritonitis and chronic affections of the abdomen. In such cases the bath may be given daily for 15 to 30 minutes.

This bath is also useful in the toxemic conditions caused by dyspepsia and pruritus. The neutral bath should not be prescribed in certain cases of eczema and other forms of skin diseases where water aggravates the symptoms, nor in cases of extreme cardiac weakness.
