Summer 2014 Dangerous for Pregnant Women

Canadian scientists warn pregnant women from staying in the southern latitudes this year. According to weather forecasts, the upcoming summer is going to be record hot, and hot weather, according to doctors, is a serious threat to the favorable course of pregnancy.

Scientists have studied three thousand births in Montreal, with the apparent risk factor of hot weather. Experts estimate that if a pregnant woman spends four to seven days at 32 degrees Celsius and higher, the probability of premature birth increases by 27%.

Giving a forecast for the coming summer, experts said that it would be particularly hot. High ambient temperature activates the contractile activity of the uterus. Furthermore, heat causes dehydration, which in its turn brings to a reduced blood flow to the fetus.

World News reports that the combination of these factors increases the production of pituitary hormones, causing premature delivery.
