Threatened with death: scientists call unexpected danger of sleep

Грозит смертью: ученые назвали неожиданную опасность сна

Long periods of uninterrupted sleep during pregnancy can cause significant harm to the child and lead to miscarriage.

Systematic continuous dream lasting more than nine hours can lead to the loss of a child even in late pregnancy.

To such conclusion scientists from the University of Michigan. During their research, they interviewed more than 150 women who have a miscarriage at 28 weeks or later.

Also, the study involved 450 women in the last stages of pregnancy and have already given birth to healthy children.

“Pregnant women often Wake up and get up in the middle of the night. And although it bothers many, the interruption of sleep helps to keep the baby,” explained doctor of philosophy, master of science, researcher of the University of Michigan in the Department of sleep medicine, Department of neurology and the Department of obstetrics and gynecology Louise O’brien.

O’brien says that further studies need to delve deeper into what may be responsible for the relationship between maternal sleep and stillbirth. Great attention should be paid to the autonomic nervous system and the hormonal system regulates while sleeping pregnancy last time.

She noted that blood pressure reaches its lowest point during sleep, and during a revival there is a jump in the activity of the nervous system, which causes transient increase in blood pressure. It is possible that these short-term increases in blood pressure can prevent long periods of low pressure.

This is important, says O’brien, because low blood pressure was related to problems with fetal growth, premature birth and stillbirth.

Smoking, maternal age, diabetes, obesity and addiction are among the established risk factors of miscarriage. However, the practice of maternal sleep covers a relatively new field of research.

“Maternal sleep is overlooked as a potential area for research the health of the mother and newborn, although it is associated with many main established risk factors for adverse pregnancy outcomes,” says O’brien.

O’brien also warns that “pregnant women should not Wake up in the night.” Very destructive sleep also has been associated with poor pregnancy outcomes, including growth restriction and premature growth.
