Why You Should Sleep On Your Left Side

  • Improved Digestion: Gravity assists waste movement through the colon when you sleep on your left side. This can promote smoother digestion and elimination in the morning [Healthline, Why Your Gut Wants You To Sleep On Your Left Side Every Night].
  • Reduced Heartburn: When you sleep on your left side, your stomach and esophagus positioning may help prevent stomach acid from flowing back up into your esophagus, reducing heartburn [Sleep Foundation, Side Sleeping: Which Side Is Best and How To Do It].

There’s also some theory that left-side sleeping might benefit lymphatic drainage and brain health, but more research is needed in these areas.

However, it’s important to find a comfortable position that allows you to sleep well. If you have any pre-existing health conditions, talk to your doctor about the best sleeping position for you. Here’s a quick summary:

  • Left recommended for: heartburn, digestion issues, pregnancy
  • Right might be better for: heart conditions (consult a doctor first)

Ultimately, listen to your body and choose the side that feels most comfortable and allows for restful sleep.
