Many people don’t realize their sleeping position could be harming their health. Experts warn that “the way you sleep influences your spine alignment, airway openness, digestion, and even pregnancy outcomes.”

Sleeping on your side, especially the left, is considered best. It “reduces back pain, eases snoring, improves digestion, and supports better circulation during pregnancy.” Doctors often recommend this position because it keeps the spine aligned and minimizes acid reflux.

Back sleeping also has advantages, helping “keep the spine neutral and reducing facial wrinkles.” However, it can worsen snoring or sleep apnea since “the airway may become blocked.” For pregnant women, it may reduce blood flow, making it less ideal.

The least healthy position is sleeping on your stomach, which “forces your neck into an awkward twist and flattens the natural curve of the spine.” This can cause back pain and even skin irritation from constant pressure on the face.

In summary, experts say to “prioritize side sleeping—preferably on your left—avoid lying on your stomach, and slightly elevate your head if you sleep on your back.” Simple adjustments like these can greatly improve your sleep quality and overall health.
