Why they work: Some experts say that weaker tongue and throat muscles are more likely to go slack, causing snoring, and that a strengthening regimen can help. One exercise: A few times a day, put your tongue tip on the roof of your mouth and make a fast tsk-tsk sound, says Steven Park, M.D., the author of Sleep, Interrupted. Feeling a bit more ambitious? Take up the didgeridoo, an Australian wind instrument. Your cheeks and tongue flex when pushing air through a didgeridoo: Playing one was shown to decrease snoring in a study published in 2005 in the British Medical Journal.
Good to know: Alcohol can relax the tongue and the throat, so avoid it before bed.
