2. Improved Digestion
It used to be considered bad to eat food before bed, because digestion theoretically slows to a near halt during that time. Now we know that this isn’t true. Digestion continues on, and not only that, your body needs a certain amount of fuel to drive the vital processes that occur during sleep (not to mention keep your heart beating and your lungs breathing).
Sleeping on the left can aid digestion because it allows food to easily move via gravity into your large intestine and then the lower colon. Our stomachs are positioned on the left as well, so sleeping that way means this heavy organ won’t lie on top of the pancreas, potentially limiting its release of pancreatic enzymes important to digestion. Left sided sleeping may therefore help your body prepare for a bowel movement first thing in the morning which, let’s face it, is a great way to start the day.
