Sleep is one of the most mundane aspects of life that is altered during pregnancy. The question that pregnant women ask most often is surprisingly straightforward: why is it that I can’t sleep on my right side during pregnancy? Although there is no one-size-fits-all solution, the answer is based on anatomy and informed by new research that is remarkably clear and has significantly improved in tone in recent years.
The logic is simpler to understand when one is aware of the internal structure of the body. Blood is returned to the heart from the lower extremities by the inferior vena cava, a sizable vein that runs along the right side of the body. If a person lies flat on their back, or to a lesser extent on their right side, the weight of their growing uterus, particularly as it enters the third trimester, may press against this vein, potentially decreasing blood flow. The oxygen and nutrients that the baby receives through the placenta may then be impacted.
Recent data presents a more reassuring picture, despite how intimidating that may sound. The stigma associated with right-side sleeping has been considerably lessened by studies released by organizations such as The American College of Obstetricians and Gynecologists and The Lancet. The right side is not regarded as hazardous for brief periods of time, even though the left side is still ideal, particularly when supported by a well-placed pillow. The most risky sleeping position is lying flat on your back, especially after week 28 of pregnancy.
Many pregnant women have discovered incredibly efficient ways to remain on their sides during the night by using body pillows and sleep wedges. To avoid inadvertent rolling, place a pillow behind your back. One between your knees, on the other hand, provides spinal alignment and eases pressure on your hips, which may become sore as your pregnancy goes on.
Prominent mothers like Ashley Graham and Serena Williams have talked about their own sleep issues during pregnancy in interviews and social media posts. Their experiences are remarkably similar to those of millions of regular women, demonstrating that getting undisturbed sleep is still difficult even with the best medical guidance and tools. Additionally, their openness is indicative of a larger movement to demystify previously taboo maternal health issues.
In the past, pregnant women were strongly advised to sleep only on their left side, which frequently caused needless stress during an already delicate time. Despite having its roots in the desire for ideal fetal circulation, this messaging has changed over time. Nowadays, medical professionals take a more empathetic, adaptable stance, discouraging extended back sleeping and promoting side sleeping generally. The logic is very obvious: extended pressure on the aorta and IVC, which run close to the spine, can impair placental blood flow and cause symptoms like lightheadedness or even fainting.
There is no reason to be alarmed if a pregnant person wakes up on their right side or back. It’s sufficient to just change positions when you wake up. During rest, the body frequently corrects itself, especially with the correct resources. Consistent, rejuvenating sleep is more important than having ideal posture.
Pregnancy-related insomnia is a remarkably prevalent issue. In addition to sleep position, rest is frequently disrupted by other factors like heartburn, leg cramps, frequent urination, and hormone surges. Because of this, doctors now advocate a more comprehensive strategy, suggesting strategies like maintaining an active lifestyle during the day, consuming fewer fluids before bed, abstaining from caffeine after lunch, and practicing mindfulness or relaxation techniques at night.
Wellness companies have entered the market recently, providing everything from contouring maternity pillows to cooling mattresses. Not all of them have scientific support, but some are surprisingly effective and reasonably priced. It’s advisable for people considering these options to put comfort ahead of marketing hype and seek individualized advice from a healthcare professional.
Crucially, the focus on safe sleep positioning represents a larger cultural shift toward maternal empowerment and goes beyond physical health. Clinicians and advocates are changing the way people experience pregnancy by substituting positive, evidence-based advice for out-of-date cautions. The emphasis is now on informed comfort rather than instilling fear, recognizing that individual differences may exist in what works best.
Due to the isolation and increased stress that many expectant mothers experienced during the pandemic, sleep health became an even more pressing concern. Online prenatal education exploded in response. Sleep hygiene is a common topic in digital courses on labor preparation, newborn care, and maternal wellness—more proof that getting enough sleep is essential for a healthy pregnancy.
Finally, it’s okay to sleep on your right side while pregnant. The right side is still regarded as safe when used sporadically and with assistance, even though the left side might have minor advantages in circulation. The most crucial thing is to pay attention to your body and get enough good sleep. It’s perfectly acceptable if lying on your right temporarily relieves hip pressure or just makes you feel more at ease.
