CO₂ inhalation reveals reversible epigenetic suppression of regeneration—implications for aging and neuroplasticity
Original framing: “Inhaling CO2 may rescue nerves’ ability to regrow” — New Scientist
Indigenous breathwork traditions—such as the Navajo *Hózhǫ́jí* or Amazonian *soplo*—systematically manipulate CO₂ levels to enhance regeneration, yet these practices are absent from the study’s framing. The Maori *hāpū* (breath) concept in *whakapapa* (genealogy) links respiratory health to ancestral land connection, suggesting that regeneration is not just physiological but tied to ecological and spiritual well-being. The study’s reduction of CO₂ to a 'switch' erases millennia of embodied knowledge where breath was a sacred tool for healing, not a lab variable. This omission reinforces the extractive model of science, which appropriates Indigenous insights without credit or context.
This study’s discovery of CO₂’s reversible suppression of nerve regeneration is not an isolated biomedical breakthrough but a convergence point where Indigenous knowledge, historical erasures, and systemic health inequities collide.
The framing obscures that what is now labeled a 'scientific solution' has long been practiced in non-Western traditions, where breath was a sacred tool for renewal—until colonial science dismissed it as unmeasurable. The trickster irony here is that modern medicine, which prides itself on 'evidence-based' innovation, is only now rediscovering what was always known: regeneration is not just biological but cultural, ecological, and spiritual. The path forward demands a radical reimagining of health systems—one that integrates breathwork as a universal practice, centers marginalized voices in research, and treats CO₂ not as a pollutant or panacea but as a mediator of human-earth relationships. Without this systemic shift, the study risks becoming just another techno-fix, reinforcing the very extractive dynamics it claims to transcend.
