INTRODUCTION:
The planetary metacrisis – characterised by breached planetary boundaries, cascading ecosystems collapse, mass extinction, intensifying climatic catastrophe and surging population health burdens [1-7] – presents the defining public health challenge of our era. Yet orthodox public health frameworks have proven profoundly inadequate to contend with the scale, causation and urgency of these interconnected challenges. Disciplinary siloing, individualised and single-issue interventions together with dehistoricised and depoliticised theories of change obscure the systemic drivers of planetary-scale illbeing [8-12]. Decolonial analysis traces the origins of the metacrisis not in abstract universal 'human activity' but in Racial Capitalism – a >500-year world system structured on the fiction of separate human races to legitimise colossal and systematic extractive violence wrought upon lands, peoples and other beings [13-17].

METHODS:
This research develops a conceptual framework for rematerialising public health's role in addressing the metacrisis – drawing on decolonial political economy [18,19], critical systems theory [20-22] and insurgent praxes which recognise the inseparability of collective healing and socio-ecological justice – generating a pluriversal (respecting diverse knowledge systems rather than imposing a universal colonial blueprint) framework for planetary health.

RESULTS:
Critical Embodiment emerges as a people's framework operationalising healing justice through three dimensions: embodiment – centring lived experience and somatic knowing; relationality – emphasising interdependence, reciprocity and responsibility across human and non-human worlds; and critical consciousness – denaturalising and rehistoricising the systems of power which sustain extractive violences. The framework reorients public health towards a Planetary Systems analysis grounded in decoloniality and Indigenous and Global Majority knowledge systems [23,24].

CONCLUSIONS:
Public health must transform into Planetary Health [25-28]. Critical Embodiment demonstrates how integrating decolonial political economy, systems analysis and healing justice creates a generative framework for collective action to address the metacrisis – repositioning public health as an instrument for planetary healing justice and regenerative futures.
