The third trimester of pregnancy is the most difficult to deal with. If you have managed to gain some respite when it comes to rest, at the end of the pregnancy, sleeping well all night will be more and more difficult.

Hormonal causes

  • Hormones are in turmoil again to prepare the body for childbirth. There is an increase in oxytocin, the hormone that acts on the uterine muscles causing the so-called contractions, but at the same time it can also cause irritability and insomnia.

Physical causes

  • The size of the baby bump in the third trimester of pregnancy is really bulky. The child is growing up and begins to occupy all the available space.
  • It may happen that the little one is agitated at night and does not make his mother rest well.
  • To all this must be added gastric reflux, which can worsen right at the end of pregnancy.

Emotional causes

  • The time of delivery is getting closer and closer and this can cause the mother to be agitated as well as nightmares. All this makes sleep discontinuous and agitated and sometimes the fear of falling asleep also coincides with the anxiety that something might happen in the night (eg the breaking of the water).
