If you’re suffering through another sweltering day this July, the effects of extreme heat may seem painfully obvious. But the fallout from soaring temperatures goes far beyond sweatiness, dehydration or heat stroke. 'There are a lot of other effects that science is starting to reveal that are problematic,' said Dr. Matthew Strehlow, a Stanford professor of emergency medicine.
In California, researchers found that babies were more likely to be born before reaching full term if their mothers weathered an 'extreme heat episode' in their last week of gestation. 'Heat acts like a trigger for preterm births,' said Tarik Benmarhnia, an environmental epidemiologist at UC San Diego's Scripps Institution of Oceanography.
