Best Sleeping Positions During First Trimester:
1. Sleeping On Side (SOS):
Lying on the side is far better than sleeping on your front or back. But the best sleeping position is on the left side. Sleeping on the right can develop pressure on the liver and your doctor will ask you to avoid that. Left would be the best position as it prevents the growing uterus from exerting pressure on the liver, allowing the fetus to get enough oxygen and nutrients via the placenta. It also improves blood circulation and reduces the energy spent in drawing the optimal blood flow for both mother and baby.
You can alternate your position to the right if you may not like sleeping on the left for a long time. You should feel free to alternate from one side to another, but make sure you do not sleep on the right for a long time.
Sleeping on one side with your knees bent is the most comfortable position.
2. Sleeping On Back:
In the initial stages of pregnancy, you can choose to sleep on the back if you are used to that position. However, as the pregnancy advances, you should avoid lying flat on your back. It is because the growing uterus exerts pressure on your back muscles, spine, major blood vessels, which therefore alter the blood flow in your body and baby.
Sleeping on the back will also give you muscle pains, swelling, and hemorrhoids. The position can cause a drop in the blood pressure levels, which may lead to dizziness. For some women, it can cause an elevation in the blood pressure and may lead to snoring and eventually sleep apnea (shallows breaths while sleeping).
Sleeping on your back, in a half-sitting position by taking the support of a few pillows is just fine and help those suffering from heartburn.
The first trimester is the right time to get yourself adjusted to sleeping on your left side, which is the ideal position.
