There are plenty of claims about the “best” sleep position – for example, it’s often thought that sleeping on your left side aids digestion.
This idea comes from basic anatomy: the stomach sits to the left, and its outlet (the pylorus) tilts slightly to the right, connecting to the small intestine.
There’s some evidence that left-side sleeping may reduce acid reflux compared to the right, as it positions the stomach in a way that makes acid less likely to creep up into the oesophagus.
If you suffer from reflux or heartburn, it certainly could be worth trying.
Sleeping on your front (prone position) can help reduce snoring and sleep apnea symptoms, but it often strains your neck and spine since your head has to turn to the side for hours at a time - Photo credit: Getty
