Pregnant women should sleep on their side in their last trimester, new research suggests.
Mothers-to-be’s sleeping positions have a significant effect on baby’s heart rates, a study found.
Foetuses’ hearts become less active when their mothers lie facing upwards as opposed to on their sides, the research adds.
Previous studies suggests sleeping on your back in late pregnancy puts excessive weight on the blood vessels that supply the uterus, resulting in reduced oxygen supply to the baby.
Lead author Professor Peter Stone from the University of Auckland, said: ‘We are suggesting that there is now sufficient evidence to recommend mothers avoid sleeping on their back in late pregnancy.’
