Health tourism

Health tourism has always existed, but it was not until the eighteenth century that it became important. In England, it was associated with spas, places with supposedly health-giving mineral waters, treating diseases from gout to liver disorders and bronchitis. The most popular resorts were Bath, Cheltenham, Buxton, Harrogate, and Tunbridge Wells. Visits to take 'the waters' also allowed the visitors to attend balls and other entertainments. Continental Spas such as Carlsbad (Karlovy Vary) attracted many fashionable travellers by the nineteenth century.
It could be argued that Britain was the home of the seaside holiday. In travelling to the coast, the population was following in the steps of Royalty. King George III made regular visits to Weymouth when in poor health. At the time, a number of doctors argued the benefits of bathing in sea water, and sea bathing as a widespread practice was popularised by the Prince Regent (later George IV), who frequented Brighton for this purpose
