In the last twenty years, research on nature and adventure has grown significantly in different fields of expertise. Effects on health have been demonstrated through various practices centred on nature and adventure (PCNA). To define their place in the psychosocial universe, this article highlights the theoretical principles on which they are based as well as the effects that have been documented. To this end, the definition of these practices will first be exposed, followed by the different disciplinary currents from which they originate and the theories supporting them. Then, the physiological, psychological, and social benefits on health will be briefly presented followed by a spectrum integrating them on an evolving framework. Finally, the strengths, limitations and issues related to the implementation of PCNA in social work will be highlighted.
