The position you sleep in every night may seem like a small habit, but experts say it can influence digestion, breathing, and overall comfort. While there is no single “perfect” sleeping position for everyone, certain positions may help or worsen specific health issues.

Sleeping on your right side, for example, may trigger more problems for people who suffer from acid reflux or heartburn. Because of the way the stomach and esophagus are positioned, lying on the right side can make it easier for stomach acid to move upward, causing discomfort, especially at night. Many people with reflux symptoms find that sleeping on their left side provides better relief.

However, right-side sleeping is not always harmful. Some people with certain heart conditions may actually feel more comfortable in this position because it can reduce pressure and make breathing feel easier. Like other side-sleeping positions, it may also help keep the airways more open compared with sleeping flat on your back, which can reduce mild snoring.

Ultimately, the best sleeping position depends on your own body and health needs. If you frequently experience heartburn, breathing problems, or discomfort during sleep, changing your position may help. A small adjustment at night could make a big difference in how rested and comfortable you feel the next day.
