Contemporary health design is undergoing an overall shift from"disease"to"health,"from"patient"to"whole person,"from"diagnosis and treatment"to"whole process,"from"hospital"to"all scenarios,"and from"product"to"system."This article proposes a theoretical framework for whole-person,whole-process health design that takes human health and well-being as its core value,adopts"whole person-whole process-all scenarios"as its fundamental dimensions,integrates preventive,clinical,and rehabilitative medicine,and takes products,services,environments,and systems as objects of innovation,supported by narrative,evidence-based,co-creative,and digital-intelligent approaches.Health design,therefore,is no longer merely an adjunct to medical technology or a means of addressing medical problems;rather,it has become an important innovation mechanism that connects medicine,technology,the humanities,and society,creates healthy lifestyles,reshapes health service systems,and fosters the development of health ecosystems.
