Climate change poses a direct threat to human health, and mounting evidence indicates that pregnant women are especially at risk of hotter than normal temperatures during the summer. A new analysis of 70 studies from around the world found that higher temperatures during pregnancy are associated with a slight increase in premature labor and fetal death, particularly in low- and middle-income countries.
Because the risk appears relatively small, scientists are concerned that it may have a significant impact on public health in the future, especially as global warming is causing temperature waves to rise more sharply and more frequently.
Elderly people, people with sicknesses and young children should be warned of the dangers of high temperatures, in addition to providing advice that aims to warn pregnant women of this phenomenon.
Pregnancy requires confronting a lot of what affects the human body, which pushes the heart to work harder, increases internal temperatures, and leaves the body exposed to the risk of heat exhaustion, exhaustion, and dehydration.
The international team concluded that "pregnant women should be placed alongside groups usually considered to be at high risk due to heat-related conditions."
This area of research is still relatively recent, but based on our knowledge so far, there is reason to be concerned about the mother and her unborn child.
None of the studies included are currently perfect or able to provide a clear cause or effect.
The research came from 24 countries, mostly in North America, the European Union, Australia and New Zealand, and of which seven were low or middle income countries.
The researchers found that: "With each temperature increase by one degree Celsius, the risk of premature labor and fetal death increases by about 5% on average, and in the event of a prolonged increase in temperature, the risk of premature labor increases by 16%."
With this in mind, the global average for preterm labor is around 10%, so the effect of intense heat - if any - is relatively small compared to all other factors that may affect the outcome of pregnancy.
The analysis showed low birth weight, for example: only 3% of births who were born during a heat wave decreased weight, and this percentage is usually much lower.
While only 18 out of 28 studies found a link between birth weight and heat exposure, 40 out of 47 studies found an association between the risk of preterm labor and exposure to heat.
It does not seem that the occupation of global warming poses a threat to the environment and to human life only, but rather affects the rate of reproduction, perhaps a few centuries after the extinction of the human race.
I got my information through the book "Man and Global Warming", which is an Arabic book ..
Do you think that global warming has other long-term damages?
Do you find global warming a serious problem now?
Do you think it is too late to treat global warming?
