To stop sleeping on your stomach, consider its consequences: snoring (due to throat irritation and swelling from acid reflux), difficulty breathing (from nasal congestion or allergies), sleep apnea (where breathing repeatedly stops and starts), and sleep disturbances (for both the snorer and bed partner). These issues can lead to daytime fatigue, irritability, and sleep inertia (grogginess upon waking). By changing your sleep position, you can alleviate these problems and improve your overall sleep quality.
