Experts recommend lying on your left side. It improves circulation, giving nutrient-packed blood an easier route from the heart to the placenta to nourish the baby. Lying on your left side also prevents expanding body weight from putting too much strain on your liver. While either side is OK, the left is better.

The best sleeping position during pregnancy is “SOS” (side sleeping) because it provides the best circulation for you and your baby. It also puts the least pressure on the veins and internal organs. Sleeping on your left side will increase the amount of blood and nutrients that reach the placenta and baby. In addition, good circulation helps reduce possible swelling, varicose veins in the legs, and hemorrhoids.

Pregnant women often feel more comfortable sleeping on their side with their knees bent, which promotes healthy circulation. Most doctors recommend sleeping on your left side specifically, as this position is thought to protect the liver and increase blood flow to the heart, fetus, uterus, and kidneys. However, the study found that there was a higher risk of stillbirth for people who slept on their backs after 28 weeks. Some experts recommend that pregnant women avoid sleeping on their backs during the second and third trimesters.

That way, if you step back, you’ll at least be tilted, which will lessen the effect of sleeping on your back. If you find that you don’t sleep and that you’re chronically tired beyond normal pregnancy fatigue, you don’t get enough sleep. The fact that you woke up in the first place is probably the way your pregnant body tells you to change your position (and maybe go to the bathroom again, another common sleep problem during pregnancy). More research is needed to determine whether or not there is an association between stillbirths and sleeping positions until 30 weeks of pregnancy.

While sleep problems can often be managed at home, sometimes a medical expert is needed to guide care or assess if there is something serious. Lack of sleep during pregnancy has been associated with longer and more painful work, higher rates of caesarean sections, and increased levels of inflammation. And sleep controls how your body reacts to insulin; not getting enough causes higher blood sugar, increasing your risk of gestational diabetes. Fluctuating hormones, changes in body systems, and stress levels fuel a series of physiological changes that can uniquely compromise sleep during pregnancy.

Their effectiveness is not reliable and there is not enough evidence to guarantee that sleeping pills do not adversely affect delivery outcomes. Pregnant women are generally advised not to take sleeping pills, although your obstetrician or midwife may recommend otherwise. Before you worry too much, understand that studies are small and that there may be other factors, such as sleep apnea, during the game.
