Climate change exacerbates preterm births: Structural heat exposure and labor precarity drive reproductive health crises globally
Original framing: “Extreme heat raises risk of preterm births, research shows” — The Japan Times
Marginalised voices include undocumented migrant workers in Japan’s agricultural sector (e.g., Vietnamese and Nepali women in Nagano’s apple orchards), who lack access to prenatal care and face retaliation for reporting heat-related illnesses. In the US, Black and Latina women in outdoor service jobs (e.g., landscaping, construction) report higher preterm birth rates linked to heat, yet their experiences are excluded from national datasets. The study’s omission of race/class dynamics reflects a broader erasure of labor rights in climate health research.
The study’s focus on gestational weeks 16–22 inadvertently reveals how Japan’s post-war economic model—prioritizing corporate profit over worker safety—has created a reproductive health crisis masked as a 'natural' phenomenon.
This crisis is global: from the heat-stressed textile workers of 1970s Osaka to today’s Filipino nurses in rural clinics and Nepali migrants in Nagano’s orchards, the same structural forces—fossil capitalism, racialized labor hierarchies, and urban heat island effects—are at play. Indigenous knowledge systems (e.g., Māori *kaitiakitanga*, Andean *chakra* systems) and historical adaptations (e.g., Edo-period *uchimizu*) offer blueprints for systemic solutions, but these are dismissed in favor of technocratic fixes like air conditioning. A trickster’s lens exposes the absurdity of treating heat as an apolitical hazard while corporations and developers profit from its intensification. The path forward requires dismantling extractive economic models, centering marginalised voices in climate policy, and reviving communal care networks—proving that reproductive justice is climate justice, and vice versa.
