Scientists from Queensland University of Technology (QUT) for the first time in the world conducted a study that found a link between increased air temperature and the rate of stillbirths, as well as premature birth.
Professor Adrian Barnett of the QUT Institute for Health and Biomedical Innovation (IHBI) conducted a study that analyzed the causes of preterm delivery in Brisbane for a four-year period from 2005.
Barnett said that during this period, a total of 101,870 births were recorded, of which 653 (0.6%) were stillbirths.
"We found that an increase in air temperature increases the risk of the birth of a dead fetus, especially in the early stages of pregnancy until 28 weeks," he said.
Analyzing the data, the researchers found that at a temperature of 15 ° C, there were 353 stillbirths per 100,000 pregnancies, compared to 610 stillbirths per 100,000 pregnancies at 23 ° C.
A rise in temperature also shortens the length of the gestation period, which leads to an increase in the birth of premature infants who often have serious long-term health problems such as cerebral palsy, visual impairment and hearing.
During the study, scientists recorded weekly temperature, humidity and air pollution levels and their effect on pregnancy.
The results showed that the lowest risks of stillbirth and premature birth were in the coolest weeks, and the highest - in hot weeks. Such results scientists connect with the fact that in hot periods to maintain comfort women often use air conditioners.
Professor Barnett said that this study is very important for public health in connection with global warming.
"Pregnant women must protect themselves from overheating in order to reduce the likelihood of premature birth or stillbirth," he said.
It is known that women during pregnancy should avoid taking hot baths and whirlpools, as this can lead to the termination of pregnancy due to dehydration caused by fever and sweating.
