We all have a favorite sleep position, but have you ever considered that it might be affecting more than just your comfort? While any sleep you can get is good sleep, research suggests that sleeping on your left side might offer unique benefits for your brain, digestion, and overall wellness.
Let’s explore the science and practical tips to optimize how you sleep.
🩺 The Science-Backed Benefits of Left-Side Sleeping
1. Enhances Brain « Cleaning »
Your brain has a waste-clearance system called the glymphatic system. Emerging research, primarily in animals, suggests that side sleeping may be the most efficient position for this process, potentially helping to clear out metabolic waste products linked to neurodegenerative diseases like Alzheimer’s.
2. Optimizes Digestion
Your stomach is naturally positioned on the left side of your body. Sleeping on your left side:
-
Allows gravity to assist in moving food waste from the small intestine to the large intestine.
-
Can help reduce symptoms of acid reflux (GERD) and heartburn by keeping the stomach below the esophagus.
3. Boosts Circulation & Is Ideal for Pregnancy
-
This position takes pressure off the inferior vena cava (a major vein that returns blood to the heart), improving circulation throughout the body.
-
For pregnant women, left-side sleeping is highly recommended as it maximizes blood flow to the placenta, fetus, and kidneys.
4. Can Reduce Snoring
Sleeping on your back can cause the tongue and soft palate to collapse backward, obstructing the airway. Side sleeping helps keep the airways open, which can significantly reduce snoring and mild sleep apnea.
