Extreme Heat

With rising global temperatures, extreme heat is a growing risk to maternal and newborn health. Pregnant individuals are more vulnerable to heat-related illnesses, which can lead to dehydration, preterm labor, and complications for newborns. Midwives are not only first responders in extreme heat, but they can also be system builders. Their presence in every phase of crisis preparedness and response ensures care remains woman-centred, respectful, and resilient.

Key Risks and Challenges:
  • Increased risk of dehydration and heat stress in pregnant individuals
  • Potential for preterm labor and birth complications
  • Medication and vaccine storage issues due to high temperatures
  • Limited access to cooling systems in low-resource settings
