Switch to Side Sleeping — The Fastest Fix
When you sleep on your back, your tongue and soft palate collapse to the back of your throat, partially blocking the airway. This is the single most common cause of positional snoring. Sleeping on your side keeps the airway open. The tennis ball trick — sewing a tennis ball into the back of a sleep shirt — has been used for decades to prevent rolling onto your back. It sounds ridiculous. It works. A 2015 study in the Journal of Clinical Sleep Medicine found positional therapy reduced snoring frequency by up to 56% in positional snorers.
Bottom line: If you only do one thing, try side sleeping for a week. Free. Immediate. No devices required.
