Experts advise that pregnant women should spend as much time possible sleeping on the left side as it helps in taking the pressure off their backs and also increases the blood flow to the uterus and the foetus. It also relieves the pressure on the spine and chances are you’ll feel more comfortable and sleep better. Moreover, it also helps in the smooth flow of nutrients to the placenta to keep the baby healthy. Bend your knees slightly and keep a pillow between your legs to be at ease while sleeping on the side.
