1. Prevents Snoring
If your spouse snores, or you’re the one aggravating your spouse with room-shaking noise all night, left-sided sleeping could make all the difference in your mutual happiness. Before you get too excited, this won’t cure all causes of snoring. But it does keep your tongue and throat in a more neutral position and leaves the airways clear.
In sleep, the mouth, throat, and tongue relax. Back sleeping is the worst for snorers, because those tissues relax backward and may partially obstruct the airway. Snoring is the vibration caused by pulling air through that crowded space.

If you’re not used to sleeping on your left side, it can take a little bit of effort to get comfortable with it. Try sleeping with a pillow between your knees or at your back to discourage rolling. Another trick, if your partner agrees, is to move to the other side of the bed. This forces your brain to decide again which position is “right” and you can more easily make a new habit of sleeping on your left side.
However you accomplish it, left-sided sleeping clearly has many benefits and may just be the key to the kind of rejuvenating sleep you’ve been missing.
