Water has been used as a valuable therapeutic agent since time immemorial. In all major ancient civilizations, bathing was considered an important measure for the maintenance of health and prevention of disease. It was also valued for its remedial properties. The ancient Vedic literature in India contains numerous references to the efficacy of water in the treatment of disease.
In modern times, the therapeutic value of water was popularised by Vincent Priessnitz, Father Sebastian Kneipp, Louis Kuhne and other European water-cure pioneers. They raised water cure to an institutional level and employed it successfully for the treatment of almost every known disease. There are numerous spas and "Bads" in most European countries where therapeutic baths are used as a major healing agent. Water exerts beneficial effects on the human system. It equalises circulation, boosts muscular tone and aids digestion and nutrition. It also tones up the activity of perspiratory gland and in the process eliminates the damaged cells and toxic matter from the system. The common water temperature chart is : cold 100C to 180C, neutral 320C to 360C and hot 400C to 450C. Above 450C, water loses its therapeutic value and is destructive.
