Because of our anatomical structure where the stomach rests on the left side, sleeping in this position uses gravity to keep stomach acids away from the esophagus, making it a helpful strategy for heartburn sufferers alongside avoiding late meals.
Similarly, while healthcare professionals often recommend side sleeping during later pregnancy for comfort, you don’t need to stay locked exclusively to the left all night, just as side sleeping alone won’t cure sleep apnea or dramatically alter lymphatic drainage.
Ultimately, the best sleeping position is the one that gives you uninterrupted, pain-free rest—using supportive pillows to relieve shoulder or hip pressure—proving that comfort and sleep quality always matter more than rigid health trends.
