Extreme Heat Poses Growing Risks to Maternal and Fetal Health

• A survey of 1,000 healthcare professionals reveals a significant rise in heat-related complications for pregnant women and newborns over the last five years.
• 73% of respondents reported an increase in maternal heat-related complications, while over 75% noted increased harm to fetuses and newborns.
• Wellcome, the research foundation that commissioned the study, is urging governments to include pregnant women in national climate adaptation plans.

Reported Health Impacts

• Approximately 25% of respondents identified pregnancy complications directly linked to extreme heat that required clinical monitoring or treatment.
• Newborns are frequently suffering from low birth weight, restricted growth, dehydration, heat-related illnesses, and difficulties with feeding, breathing, and temperature regulation.
• Over 90% of healthcare professionals surveyed stated they need more resources and training to manage these heat-related risks effectively.

Localized Interventions

• The HAPI study in Zimbabwe and South Africa is evaluating low-cost, community-designed solutions to protect pregnant women.
• Key strategies being tested:
  • Smartphone-based heat alert systems relayed by community health workers.
  • Cooling kits and reflective roofing to regulate indoor temperatures.
  • Community-led efforts such as male 'heat champions' who assist with water collection and task sharing to reduce physical exertion.

Global Context and Policy Implications

• Simon Stiell, head of the UN climate change framework, labeled heat as a 'new faultline' in the climate crisis that threatens to widen existing health inequities.
• The findings highlight the urgent need for funded, targeted measures in climate policy to protect vulnerable mothers and infants from rising global temperatures.
