The increase in temperature of the Earth reduces the duration of pregnancy
Source:
Extreme heat can induce premature labour for up to two weeks.
Everyone knows that the normal duration of pregnancy in women is 40 weeks or 9 months. Despite the fact that the birth of a child is not always in the expected day of, in the medical practice , if he was born within 38 to 42 weeks. For the duration of pregnancy often influence a woman's age, overall health and lifestyle of the expectant mother, but now scientists have new data that suggests that the thermal effect also increases the risk of premature birth. On existing statistical data, from 1969 to 1988 in countries with a warm climate, there was a sharp increase in revenues to medical facilities for childbirth in the most hot summer days.
Why the heat provokes preterm labor?
The Marked increase in the number of births in particularly hot days, indicates that the extreme impact of the ambient temperature . According to an article published by the portal , an average of 25,000 children per year are born earlier than expected as a result of exposure to heat. Scientists say that climate change and rise in temperature in the future, women will have greater risk of preterm birth than before. Due to the fact that premature infants have not fully developed, the newborn may die as a result of cardiopulmonary insufficiency or . But, fortunately, modern medicine allows us to save a premature baby, even if he is born on the 26-week period.
26 weeks pregnant baby weight in average is about 760 grams with a growth of just 35 cm
Using data from climate models for the end of this century, researchers considered that pregnant women in the future will be prone to premature childbirth 2 times more. Thus, at the end of XXI century the number of premature births is 42 000 per year. To identify the exact reasons for such extreme impacts of climate change on the pregnant woman, scientists have yet to figure out the processes that occur in the human body in response to increasing temperatures. At this stage, scientists suggest that sudden changes in ambient temperature adversely affect the cardiovascular system, causing a disruption in its work and provoking premature birth. It is assumed that the high temperature is able to increase the level of oxytocin — a hormone that actively participates in the processes of pregnancy and nursing.
