Doctors recommend sleeping on an incline, which allows gravity to keep the stomach’s contents where they belong. But sleeping on your side can also make a difference — so long as you choose the correct side. Several studies have found that sleeping on the right side aggravates heartburn; sleeping on the left tends to calm it.
The reason is not entirely clear. One hypothesis holds that right-side sleeping relaxes the lower esophageal sphincter, between the stomach and the esophagus. Another holds that left-side sleeping keeps the junction between stomach and esophagus above the level of gastric acid.
In a study in The Journal of Clinical Gastroenterology, scientists recruited a group of healthy subjects and fed them high-fat meals on different days to induce heartburn. Immediately after the meals, the subjects spent four hours lying on one side or the other as devices measured their esophageal acidity. Ultimately, the researchers found that “the total amount of reflux time was significantly greater” when the subjects lay on their right side.
In addition,” they wrote, “average overall acid clearance was significantly prolonged with right side down.” In another study, this one in The American Journal of Gastroenterology, scientists fed a group of chronic heartburn patients a high-fat dinner and a bedtime snack, then measured reflux as they slept. The right-side sleepers had greater acid levels and longer “esophageal acid clearance.” Other studies have had similar results.
THE BOTTOM LINE Lying on your right side seems to aggravate heartburn. 🌟 @CSunshare 😈 🌟 💫TUNE IN💫
