Health tourism is a tricky one to define. It is more of an umbrella term, encompassing both wellness tourism and medical tourism. These two types of tourism may seem quite different, but they both fundamentally have health at their core. So, health tourism can be defined as follows:
Health tourism covers those types of tourism which have as a primary motivation, the contribution to physical, mental and/or spiritual health through medical and wellness-based activities which increase the capacity of individuals to satisfy their own needs and function better as individuals in their environment and society.
This definition comes from an executive summary published by the World Tourism Organization and the European Travel Commission in 2018. As you can see, the exploration of health tourism in itself is a relatively new idea. The two organisations also provided the following definitions of wellness and medical tourism respectively:
Wellness tourism is a type of tourism activity which aims to improve and balance all of the main domains of human life including physical, mental, emotional, occupational, intellectual and spiritual. The primary motivation for the wellness tourist is to engage in preventive, proactive, lifestyle enhancing activities such as fitness, healthy eating, relaxation, pampering and healing treatments.
Medical tourism is a type of tourism activity which involves the use of evidence-based medical healing resources and services (both invasive and non-invasive). This may include diagnosis, treatment, cure, prevention and rehabilitation.
