Increased Risk of Acid Reflux (GERD / Heartburn):

• Why: Sleeping on your right side relaxes the lower esophageal sphincter (the muscle between your stomach and esophagus). This allows stomach acid to flow more easily back into the esophagus.

• Alternative: Doctors often recommend sleeping on your left side if you suffer from acid reflux, as this position keeps the junction between the stomach and esophagus above the level of gastric acid.

Impact on Digestion:

• Why: The stomach naturally sits on the left side of the abdomen. Sleeping on the left side allows gravity to assist the movement of food through the digestive tract. Sleeping on the right side can slow down digestion or cause discomfort for people with sluggish digestion.

Cardiovascular Health and Circulation (Especially for Pregnant Women):

• Why: Sleeping on the right side can exert pressure on the inferior vena cava (the large vein that carries blood back to the heart from the lower body).

• Alternative: Pregnant women are typically advised to sleep on their left side to maximize blood flow and nutrient delivery to the fetus and placenta.

Benefits of Side Sleeping (In General):

• Spinal Alignment: Sleeping on either side helps keep the spine relatively aligned and reduces lower back pain, especially when using a pillow between the knees.

• Reduced Snoring and Sleep Apnea: Side sleeping keeps the airways open compared to sleeping flat on your back.
