- Taking the Heat: Potential Fetal Health Effects of Hot . . .
Although extreme heat may affect fetal growth late in pregnancy, exposure to hotter-than-usual weather early in pregnancy may affect other aspects of fetal development For instance, two recent studies have reported an association between maternal heat exposure during the first few weeks of pregnancy—when fetal heart development begins—and
- Cumulative effects of extreme ambient temperatures on . . .
As shown in Fig 1 and Table 3, the strongest heat effect was observed at 27 days of exposure at 34 °C, with an estimated percent change in PlGF of −48 27 (95% CI: 64 33, −24 98) The strongest cold effect was observed at 30 days of exposure at −4 °C, with an estimated percent change in PlGF of −44 23 (95% CI: 63 28, −15 30)
- Evaluating the Impact of Heat Stress on Placental Function: A . . .
Heat exposure was administered via a climatic chamber with a heating system that maintained the air temperature at 37 °C and the relative humidity at 60 to 70% from 08:00 to 16:00 h; after this period, the heating system was turned off and the air temperature and humidity returned gradually to the environmental conditions Placental weight
- The Impact of Extreme Heat Exposure on Pregnant People and . . .
INTRODUCTION Exposure to extreme heat is a growing global health concern By 2070, it is estimated that, without migration, one-third of Earth's population will reside in areas with annual average temperatures greater than 84 2°F (29°C), currently only experienced in less than 1% of Earth 1 Heat waves were the deadliest meteorological hazard over the past 30 years in the United States 2
- Effect of Elevated Ambient Temperature on Maternal, Foetal . . .
Nine studies employed apparent temperature (combined effect of air temperature and relative humidity) to identify the exposure effects on elevated ambient temperatures on pregnant women and neonates [11,12,32,33,34,35,36,37,38]
- Ambient temperature, heat stress and fetal growth: A review . . .
Climate change will continue to increase population exposure to elevated ambient temperatures and extreme heat events globally (IPCC, 2022) The frequency and intensity of heatwaves is increasing (Watts et al , 2018) and among the weather-related events exacerbated by climate change, heat poses one of the greatest threats for human morbidity and mortality (Kuehn and McCormick, 2017)
