According a new study published in The Lancet, global warming increases the risk of preterm birth.
A critical period of heat exposure
To reach this conclusion, the researchers chose for the first time to analyze the course of pregnant women living in a temperate zone in Germany. They then found that extreme heat and prolonged periods of heat exposure increased the relative risk of preterm birth among German women followed.
The researchers also identified a critical period of heat exposure ranging from the 34th week of gestation to the 37th. Another lesson of the study: pregnancies with a female fetus were more prone to premature births associated with heat stress. The study also demonstrated that heat exposure was associated with impaired vascular resistance in the uterine artery, a key factor in fetal development and growth.
Ensure active surveillance of women at risk
“Heat stress caused by high ambient temperatures increases the risk of preterm birth, even in a geographic region with a temperate climate. Antenatal care should be reviewed in all such regions to ensure active surveillance of women at risk “, conclude the researchers.
It is also essential that future mothers consider these results and be aware of their exposure to heat during pregnancy.
Global warming develops certain diseases
Global warming is the cause of the development of many diseases. Dengue fever, West Nile fever and malaria are the best known examples of diseases that will spread as a result of global warming.
Excessive heat associated with periods of heat wave is another consequence of global warming, which can cause exhaustion, dehydration and heatstroke. Finally, air pollution, which is aggravated by global warming, is the cause of many respiratory problems.
