Hot weather and premature birth

Hot weather and premature birth |Discover the relationship between hot weather and premature birth. The worldwide rise in temperature is being attributed to a number of environmental problems, but one of the effects is the premature birth of pregnant women. The University of California Los Angeles UCLA research examined the birth records of more than 50 million US citizens from 1969 to 1988. Researchers discovered that when the temperature rises, the birth of babies takes place on average 6.1 days before the date of birth, while the duration can go up to 2 weeks. On a day when the temperature is higher than 32 ° C, the rate of birth increases by 5% over the other days. Researchers believe that warmer temperatures result in changes in hormones in pregnant women, which increases the chance of premature birth. He said the problem will only get worse in the near future as climate change will make hatchways more common.

Researchers are unable to say with certainty about the biological mechanisms underlying the pregnancy of hot temperatures, but they believe that heat increases the pressure on the arteries passing from the heart to the baby’s early birth happens. Another possibility is that warmer temperatures increase the amount of hormone oxytocin that plays a role in the birth of a baby. However, in areas where the weather is already hot, this effect is not seen because pregnant women are likely to become accustomed to this temperature. Researchers discovered that high temperatures between 1969 and 1989 resulted in the premature birth of 25,000 babies annually. Researchers also say that because the data they reviewed was 30 years ago, the impact of the weather may be higher than expected. According to a worldwide estimate, one in every 10 babies is premature, most of them healthy, but the risk of various complications is high and soon after birth, and development can be affected. The results of this research were published in the journal Nature Climate Change.
