Quick Way To Ease Heartburn

The Claim: Lying down on your left side eases heartburn.

The facts: For people with chronic heartburn, restful sleep is no easy feat. Fall asleep in the wrong position and acid slips into the oesophagus, a recipe for agita and insomnia.

Doctors recommend sleeping on an incline to allow gravity to keep the stomach’s contents where they belong.

However, 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, while sleeping on the left tends to calm it.

The reason is not entirely clear. One hypothesis holds that right-side sleeping relaxes the lower oesophageal sphincter, which lies between the stomach and the oesophagus.

Another holds that left-side sleeping keeps the junction between the stomach and the oesophagus above the level of gastric acid.

In a study in The Journal Of Clinical Gastroenterology, scientists recruited a group of health 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 oesophageal acidity.

Ultimately, the researchers found that “the total amount of reflux time was significantly greater” when the subjects lay o their right side.

In addition, the average overall acid clearance was significantly prolonged with the right side down.

In another study, this one in The American Journal Of Gastroenterology, scientist 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 “oesophageal acid clearance”.

Other studies have had similar results.

The bottom line: Lying on your right side seems to aggravate heartburn.
