A Note on Pregnancy
If you’re pregnant, this message is for you: sleep on your left side.
After the first trimester, sleeping on your back can compress the vena cava, reducing blood flow to your heart and your baby. Sleeping on your right side is safer than back but still slightly compresses this vessel. Left side is optimal.
The American College of Obstetricians and Gynecologists recommends left-side sleeping for pregnant individuals. Use pillows behind your back and between your knees for comfort.
The Bigger Picture: Sleep as Health Practice
Changing your sleep position won’t cure disease or replace medical treatment. But it’s a perfect example of how small, consistent adjustments can support your body’s natural processes.
Think of it this way: you’re already spending 6-9 hours in bed tonight. Why not spend those hours in a position that helps—not hinders—your digestion, circulation, and waste removal?
It costs nothing. It requires no pills, no equipment, no special diet. Just a gentle shift in how you rest.
That’s the kind of health advice we can all use.
