In recent business activities, well-being-based management approaches have become increasingly important. Consideration of consumer well-being is one of them. In particular, social demand and interest in health are incredibly high, and the health-related services market has significantly expanded. However, since the WHO's definition of health was established, the concept of health has become multi-dimensional. There is much overlap with other concepts, such as well-being and quality of life. As a result, even for health-related services that are supposed to contribute to consumers' health, the critical term "health" is still used ambiguously by both service providers and consumers. It could increase the uncertainty of the benefits of the services and cause difficulties in the continued use of services for consumers.
