Lack of sleep is also thought to increase the risk of high blood pressure. It is important that pregnant women are as well rested as possible in order to help them through the ordeals of labour, childbirth and early motherhood. Labour is likely to be a draining physical experience, so to start with being well rested is important.
Not all women find sleeping difficult during the first trimester. Fatigue during the first 12 weeks of pregnancy is common. This early period of tiredness is thought to be due to the hormonal changes. Emotions tend to be running high during these early days as well, partly due to hormones and partly because it can be quite hard to process the huge news that she is going to be a parent. Nausea can also keep women from drifting off, or cause them to wake early.
During the early stages of pregnancy, it is fine to sleep on the tummy. By the time it becomes dangerous to the baby, the would-be mother will be too uncomfortable doing it. One need not worry about the sleeping position at all during the first trimester.
Some women tend to experience a spurt of energy levels during the second trimester, which can come as a relief after a very sleepy start to their pregnancy. Women tend to have fewer sleep interruptions too. Typically there is less nausea and their emotions are more under control.
Once she is in the second trimester, she should avoid sleeping on her back. If the pregnant lady is lying on her back, her uterus puts pressure on the vein that returns blood to her heart. This could cut off the blood supply to the baby and may cause dizziness and nausea. As she is near the end of the second trimester, the bump may begin to be more noticeable and she may find getting comfortable more difficult. Sleeping on the side or the left side in particular is necessary.
Most pregnant women will agree that it is during the final months of pregnancy that they face problems sleeping. It is important to find a comfortable and safe sleeping position, even if that means using cushions or pillows, or anything else that supports her comfortably. The most obvious problem is the size of the bump, which grows quickly during the last trimester.
During pregnancy, lying on the right hand side is much better than sleeping on the front or back during the later stages of pregnancy. It is still not as good as sleeping on the left. This is because; sleeping on the right hand side can put pressure on the liver so it is best to avoid this position.
Doctors recommend sleeping on the left-hand side. This position prevents the heavy uterus putting pressure on the liver and continues to allow the baby to receive the right amount of nutrients and oxygen. In fact, not only does this position not restrict blood flow, it actually improves circulation.
