10. Evolution of Demand for Portuguese Thermal Spas: An Exploratory Data Analysis of Administrative Data

Well-being or positive health is not a new concept; However, since the mid-twentieth century, scientific institutions have addressed the issue and its implications for medicine and public health. It can be observed that wellness and healthy living are becoming more and more important in society. Consequently, there is an increased need to look for products and services that mitigate the risk of these diseases associated with modern society. Thus, a fusion between tourism and wellness emerges, with thermal spas being an essential factor in the health and wellness promotion equation. In Portugal, thermal services are well known. However, the demand for its services is subject to difficulties well observed during the COVID-19 pandemic. Therefore, it is fundamental to characterize the Portuguese thermal market on the demand side to segment it and find the best strategy to meet the user needs. Secondly, it is relevant to understand the weight of each segment in the market. Focusing on the division between classic thermal services—considered therapeutical health services—and wellness services provided by Portuguese thermal establishments, this research aims to characterize the thermal market on the demand side. In particular, the study seeks to understand how wellness services are evolving regarding the total demand for Portuguese thermal establishments. Based on the descriptive analysis of administrative data of registers in all the Portuguese thermal establishments, it is possible to conclude that the increasing demand for thermalism products and services (both therapeutic and wellness) suffered a severe crash with the financial crisis and the Covid-19 pandemic. Age is an essential factor that distinguishes the market segment of the therapeutic thermal offer. The consumers of such a thermal component are older than the ones demanding wellness services. Finally, specific international markets (France, Spain, and the United Kingdom) become more important in the user’s segments.
