Can you sleep on your right side during the second trimester of pregnancy?
In general, sleeping on the right side is acceptable during the second trimester of pregnancy, but it should not be maintained for prolonged periods. The specific reasons are as follows:
As pregnancy progresses, pregnant women may find it increasingly uncomfortable to sleep, so they should choose a position that feels most comfortable. During the second trimester, the uterus gradually enlarges, which may cause discomfort such as stomach upset or indigestion. Sleeping on the right side positions the stomach relatively lower, helping to alleviate these symptoms. However, prolonged right-side sleeping may compress the aorta and iliac arteries, potentially impairing blood circulation in the uterine artery and placenta; therefore, this position should not be sustained for too long.
Pregnant women in the second trimester should prioritize comfort and safety when choosing a sleeping position and avoid maintaining the same posture for extended periods. Placing small pillows under the knees and along the back can help support the body, reduce strain on the lower spine, and promote a more comfortable sleeping posture.
