Not always easy to find sleep during pregnancy. And as the term approaches, finding the right place to sleep becomes a real headache for future mothers. Many moms opt for posture of sleeping on the back, this one should be avoided. According to a recent study published in the journal The Journal of Physiology, conducted by researchers at the University of Auckland, New Zealand, sleeping on the back in late pregnancy would increase the risk of stillbirth or fetal deaths.
Changing the fetal heart rate.
Recent studies on late stillbirth have demonstrated the importance of the sleep position in the risk of intrauterine death. This study was designed to evaluate the effects of different maternal positions on fetuses with no health problems.
To carry out their study, scientists followed 29 healthy pregnant women. All were then in their third trimester of pregnancy. They then had to lie down in different positions for periods of 30 minutes. The scientists then calculated the variability of the fetal heart rate.
All women were followed until they gave birth, and all the babies were healthy when they were born. However, the team found some information about the effects of maternal positions on fetal health. The researchers found that when mothers were lying on their backs, the position changed the heart rate and activity of the baby, resulting in reduced oxygen supply. This may increase the risk of stillbirth.
Compression of the main veins involved
We think that staying flat on the back compresses the main veins bringing blood back to the mother’s heart,” said Professor Stone, lead author of the study, at Medical News Today. From this case, the cardiac output of the future mother can drop and the placental flow is reduced. We think that many mothers and babies can cope, but others do not, he adds.
