5. Reduces Pressure on the Spine and Back

Benefits include:

Potential benefits:
- Reduced snoring
- Improved airflow
- Lower risk of airway collapse
7. Especially Beneficial During Pregnancy
Left-side sleeping is frequently recommended during pregnancy, particularly in the later stages.
Benefits include:
- Improved blood flow to the placenta
- Reduced pressure on the liver
- Better oxygen and nutrient delivery to the baby
