Scientists told why pregnant women in the late periods can not sleep for long
Researchers from the University of Michigan were able to justify danger of long sleep for pregnant women in late. They found that continuous sleep for more than 9 hours can harm the mother and fetus, and also increases the likelihood of complications during childbirth.
Participated in the experiment were 153 women who had premature birth at 28 weeks and a little later, as well as 480 women in the final weeks of pregnancy.
Scientists have suggested that the traditional for many expectant mothers in the late term insomnia - a kind of protective mechanism - if the expectant mother wakes up several times during the night, it means that for some reason it is necessary.
Experiments have shown that waking up in the middle of the night is important for raising the level of blood pressure, because in deep sleep the pressure decreases. Thus, each awakening of a pregnant woman is an episode of the activation of her autonomic nervous system. But too frequent awakenings are bad too.
Too deep uninterrupted sleep, as well as too restless sleep, equally increase the likelihood of premature labor, prolonged labor, intrauterine hypoxia.
Therefore large-scale fighting with insomnia in the third trimester of pregnancyaccording to researchers, it makes no sense. If a woman wakes up 2-3 times a night, this is a normal defensive reaction that does not need treatment.
