That doesn't mean everyone needs to sleep on the left. But if you regularly wake up with heartburn, your sleeping position may be something to discuss with your healthcare provider.
2. Your right side may feel better for some people
Although the left side is often discussed in relation to reflux, that doesn't mean right-side sleeping is unhealthy.
Some people simply find the right side more comfortable, and for many healthy adults, comfort and sleep quality are important considerations.
If sleeping on your right side helps you stay asleep without discomfort, there may be no reason to force yourself into another position.
3. Side sleeping can help some people who snore
Your sleeping position can influence your airway.
For some people, sleeping on the back allows the tongue and other tissues to move backward and narrow the airway, potentially making snoring worse.
Sleeping on your side may help keep the airway more open and can reduce snoring for some people.
