The main objective of this theorization is to reflect on human care, starting from the identification of the paradigmatic crisis and the changes required to move from a biomedical model to a transforming model based on human care science. The meth-odology was a theoretical study of reflection based on the theory of human care and the cosmocene ecological theory. The main results show that the ontological under-standing models expand the vision of human health care to a vision that involves an understanding of the care of the environment, they are an important contribution to the field of human and health sciences that can serve to guide new ways of being and acting. It is concluded that it is in the concept of unitary ontological literacy where nurses have skills that imply awareness, reflexive and intentional ways of being that lead to the healing and fulfillment of patients, family members, col-leagues, and the environment. In the health area, understanding the need for a change towards care philosophies allows us to move towards health-generating paradigms.
