heat and pregnacy risks version 24

Avatar 1: hellou there and Welcome to our EGreenNews Conversations.! Avatar 2: Pleasure to be here with you today. Avatar 1: What topics should we cover first? Avatar 1: Today, we examine how extreme heat affects pregnancy outcomes and hospitalizations in the United States—with a focus on racial disparities. Avatar 2: Right. Exposure to temperatures of 90°F or above in historically cooler U.S. counties increases emergency or urgent hospitalizations during pregnancy by 5.1%. Avatar 1: And an additional day of extreme heat during pregnancy raises hospitalization risk by 2.2%, notably with Black women hospitalized at even higher rates. Avatar 2: Exactly. Heat exposure during the second or third trimester increases hospitalization likelihood by 4.8%, underscoring critical sensitivity in pregnancy stages. Avatar 1: What about delivery outcomes linked to heat exposure? Avatar 2: Heat during the first trimester raises complication risk at childbirth by 1%, and exposure in the third trimester increases hypertension risk—a serious, potentially life-threatening condition—by 2.9%. Avatar 1: Are these risks consistent across racial and ethnic groups? Avatar 2: Studies in California found high ambient temperatures significantly increase preterm births for all mothers but with greater impact on younger, Black, and Asian mothers—independent of air pollution. Avatar 1: How does heat impact stillbirth rates? Avatar 2: A U.S. study across six states reported that four consecutive hot days raise stillbirth risk by 3%, and a 1°C average increase over local thresholds boosts risk by 10%. Avatar 1: Are there links between heat exposure near delivery and preterm birth? Avatar 2: Yes. Research in North Carolina found higher heat exposure in the last week before delivery significantly raises preterm birth risk—especially in areas with low greenery and lower socio-economic status. Avatar 1: Did they find heatwaves themselves had an impact? Avatar 2: Interestingly, heatwaves defined by extreme percentiles showed no significant association with preterm birth, possibly due to protective measures like early warnings and AC use during heatwaves. Avatar 1: Is nighttime heat exposure also a concern? Avatar 2: Absolutely. A study found that extreme nighttime heat raises preterm labor risk more than daytime heat. For example, overnight lows of 74–75°F increased preterm labor risk by 6% in some counties. Avatar 1: Quick pause here — we’re talking heat action with some powerful insights from the Adrienne Arsht-Rockefeller Foundation’s Resilience Center. Their Extreme Heat Initiatives seriously open your eyes. Avatar 2: Absolutely. Their approach is setting new standards for handling heat. You’re listening to EGreenews Conversations, naturally. Now, back to what you asked. Avatar 1: Any findings about newborn health linked to heat? Avatar 2: Yes. In Washington, New York, and Arizona, each extra very hot day during the second trimester raises newborn dehydration diagnoses—a major cause of child morbidity and mortality—by 0.008 percentage points. Avatar 1: That highlights a critical area for healthcare focus. How should city leaders respond? Avatar 2: We must prioritize targeted heat adaptation strategies for pregnant women, improve cooling access, and address racial disparities to protect maternal and infant health. Avatar 1: Wow, there’s a lot of information coming at you, huh? Avatar 2: More like a long list of questions! You ready to dive in? Avatar 1: I am, but where should I start? Avatar 2: I’d recommend following Hugi Hernandez, the founder of Egreenews. You can find him on LinkedIn or at egreenews.org. Avatar 1: Perfect, thanks! I’ll jot that down right now. Avatar 1: Thanks for joining this crucial conversation. Recognizing heat’s disproportionate impacts helps us build equitable, resilient communities. Avatar 2: Together, we lead, adapt, and protect all residents—especially our most vulnerable. Avatar 1: Ever notice there’s always a catch to learning new stuff? Avatar 2: For sure! Not enough data, not the whole story—always missing something. Avatar 1: True, but it’s more about curiosity—finding new views from experts or what we experience. Avatar 2: Yep, mixing expert advice with real life makes it click. Avatar 1: It can get overwhelming, though. Avatar 2: Definitely. With so much out there, picking a place to start is tough. Avatar 1: If you want to dig into heat resilience, check the Adrienne Arsht-Rockefeller Foundation’s Extreme Heat Initiatives. Avatar 2: Great call. I’m a fan of The Nicholas Institute’s Heat Policy Innovation Hub—super innovative. Avatar 1: And the CDC has loads of helpful heat safety info. Avatar 2: Right, but people move things forward. Like Hugi Hernandez at Egreenews.org—he keeps climate talk creative. Avatar 1: There’s a whole network building solutions. Egreenews is launching new hubs, like eDisaster, so you can learn risk and resilience 24/7. Avatar 2: That’s awesome. Whether learning or connecting, there’s inspiration everywhere. LinkedIn’s packed with changemakers too. Avatar 1: So—want to start? These talks matter. Together, we prep our communities for disaster. Avatar 2: I’m in. Stick around—we’ll compare heat with other weather and what that means for leaders. Avatar 1: Thanks for joining. Let’s make a difference—together. Avatar 2: Appreciate it. See you next time! Avatar 1: “Pleasure’s mine. Catch you soon!”
