Extreme Heat Poses Hidden Dangers to Pregnant Women

Extreme heat is increasingly linked to adverse pregnancy outcomes, including low birth weight and pre-eclampsia, with significant implications for maternal and newborn health. Even in temperate climates like the UK, temperatures unaccustomed to prolonged heat can strain bodies, particularly during pregnancy. This issue is unfolding now, with 73% of surveyed healthcare professionals across several countries reporting an increase in heat-related pregnancy complications over the past five years.

Despite clear evidence, maternal and newborn care is largely overlooked in climate adaptation planning. Many heat-health strategies fail to identify pregnant women as a specific risk group. To address this, a global call to action has been launched, advocating for stronger healthcare preparedness and dedicated clinical guidelines. In the UK, specific measures are urged for heat-health planning within maternity services, while globally, the WHO is called upon to establish clinical guidelines for heat and pregnancy.

Practical solutions are achievable, including basic ward cooling and staff training, with 92% of healthcare professionals requesting dedicated resources. However, systemic integration of heat preparedness into national policy and maternity reforms is crucial. As climate change intensifies, proactive measures are vital to safeguard future generations.
