Whether you are sleeping on the left side or your back, it is crucial to keep your head elevated to promote digestion in bed. Several studies reveal that sleeping on the left side with your head elevates aids in reducing the symptoms of heartburn.
Basically, it causes the lower esophageal sphincter (LES), which is the muscle ring responsible for regulating the stomach’s consumption of food present in the oesophagus, which remains higher than the levels of gastric acid.
If acid reflux occurs, the pull of gravity will suck the acid back towards the stomach. The idea is to keep the head in a neutral position, and you will need the support and comfort of a sturdy and plump pillow.
