Cooling Poverty Affects 2 Billion as Heat Risks Swell

• More than 2 billion people worldwide face "cooling poverty," lacking safe or affordable means to protect themselves against life-threatening heat.
• Cooling poverty is a multidimensional issue involving inadequate housing, poor healthcare, and lack of information, rather than just a absence of air conditioning.
• South Asia and Sub-Saharan Africa are the most affected regions, with millions suffering from a lethal combination of geographic vulnerability and systemic economic inequality.

Scope of the Crisis

• A study in Nature Sustainability analyzed over 1 million households across 28 countries:
  • 1.2 billion people live in moderate cooling poverty.
  • 550 million face severe cooling deprivation.
  • 600 million experience high, multi-dimensional deprivation.
• Approximately 2.2 billion people suffer from cooling poverty specifically related to educational and labor standards.

Risk Factors

• Housing: Low-quality materials like tin or asbestos roofs can make indoor temperatures up to 5 degrees Celsius hotter than outdoors.
• Infrastructure: Lack of reliable electricity, safe water, and sanitation limits hydration and cooling capabilities.
• Vulnerability: Outdoor workers, women, children, the elderly, and minorities are disproportionately affected due to lack of adaptive resources and limited healthcare access.
• Geography: South Asia faces extreme heat-humidity combinations that impede natural body cooling (sweating), while Sub-Saharan nations like Ethiopia, the DRC, Rwanda, and Malawi lack basic protective infrastructure.

Proposed Interventions

• Cooling experts emphasize that distributing air conditioners is unsustainable due to energy demands and fragile grids.
• Strategic policy recommendations:
  • Urban planning: Increasing green and blue spaces (trees, parks, water bodies).
  • Retrofitting: Using solar-reflective white paint on roofs and affordable insulation like straw or clay.
  • Labor protection: Mandating rest breaks for outdoor workers and providing financial compensation during extreme heat.
  • Governance: Implementing heat-health action plans and climate-sensitive building codes.
• Experts caution that there are inherent limits to human adaptation to extreme heat, necessitating broader climate action.
