The term non-pharmacological intervention (NPI) was not chosen by the scientific society NPIS but has become necessary. It has been used by scientists since 1975. Various authorities and agencies have adopted it, including the World Health Organization since 2003, the French National Authority for Health since 2011, the National Solidarity Fund for Autonomy since 2014, the Ministry of Health since 2018, the High Council for Public Health since 2019, the European Centre for Disease Prevention and Control since 2020, the General Inspectorate of Social Affairs since 2022, the Economic, Social and Environmental Council since 2023, and Health Insurance since 2024. Many national and supranational scientific societies use the term NPI in their recommendations. These health solutions are often "squeezed" between health products and public health measures, despite efforts by professionals to raise awareness and recognition of them. They represent an underestimated area of intangible services situated between goods (e.g., medications, medical devices) and general public health recommendations (e.g., dietary rules, hygiene measures, environmental actions).

They can be lost in compilations of health solutions that mix health promotion actions with targeted programs or confuse methods for identifying a health problem with methods for resolving it. The challenge is to improve the traceability of practices for continuous enhancement of their quality, safety, implementation, and training. These practices can be easily shared from one country to another. The term NPI does not imply "anti-medication" or "alternative medicine" (parallel medicine). Instead, it draws from the rigor of the globally standardized drug validation process to establish good scientific and clinical practices. Over time, we believe that the abbreviation NPI will come to be more widely recognized than its full title, similar to WHO, IBM, SEAT, and many others.

Registers of non-pharmacological practices with imprecise criteria and boundaries.
Catalogs compile various health practices among which NPI may be submerged. Some target the general population, while others are more specific. The selection criteria are heterogeneous, and objectives and practical modalities vary widely. Three examples include two from the United States (EBCCP and Mindtools) and one from France (Capitalisation Santé).

Immaterial practices of prevention and care have existed since ancient times. However, the diversification of practices, the multiplication of professions at the intersection of prevention, care, and social assistance, and the globalization of information systems have leveled these services and obscured them at a time when medicine has made significant advances in the early detection and diagnosis of health issues. The interdisciplinary and multisectoral approach of the NPIS generates a value chain, from the design of practices to their implementation, regulation, and financing.

Innovative economic model initiatives are emerging worldwide, including fee-for-service, bundled payments, social economy provisions, offers promoting sustainable development, e-health economy, human innovation bundles, and long-term economy (World Economic Forum, 2024). The NPIS Prospective Pole, led by Michel Noguès, documents these initiatives in books (Noguès, 2022; Noguès, 2024). The NPIS Forums invite all innovators to share their experiences.

Moving, eating, drinking, sleeping, talking, reading, writing, painting, listening to music, watching a movie, dancing, laughing, walking, singing, meditating, gardening, socializing, etc., are all activities of daily life. Some of these can generate joy, pleasure, personal growth, and well-being. In a democratic country, everyone is free to interpret and experience these activities in their own way. This relates to life philosophy, lifestyle, the art of living, and personal development. In other words, a daily activity is not an intervention, even if it can occasionally and randomly contribute to the health of certain individuals. Occupational activities and treatments for health problems identified by medicine are different.
