The Taiwanese government's promotion of the hot spring industry has given the sector diverse purposes, including tourism, leisure, and recreation; medical and health care; geothermal energy production; and agricultural and fishery practices. Currently, hot springs are mostly used for commercial purposes such as tourism and leisure. Unlike past studies, which targeted a single region and adopted non-random questionnaires, this study employed random phone interviews on a national scale. Nearly 50% of the interviewees had been in a hot spring during the past year, mostly for the purposes of "tourism and leisure" and "fatigue relief." When choosing a hot spring, the factors of interest were "tidiness of the hot spring venues" and "cleanliness of the spring water." The majority of the interviewees recognized the advantages of hot springs; yet, a relatively small portion of them had knowledge of the quality control at hot springs. This study suggested that, in addition to integration of hot springs with leisure and tourism, the government should advise hot spring facilities to obtain hot spring certifications and utilize multifarious channels to advocate the hot spring management policy, including the standard for the quality of the spring water and the significance and recognition of the "Certified Hot Spring" mark, to educate the public on proper health knowledge regarding hot springs.
