These moves from the journal Chest can help firm up your soft palate. If you do them 3 times a day, it’ll reduce snoring frequency by 36%…
The first stop-snoring move: Press as much of your tongue as possible against the roof of your mouth 20 times.
Next: Push the tip of your tongue against the roof of your mouth and slide it backwards 20 times.
Another stop-snoring exercise: Lift the back of the roof of your mouth like you’re saying “ah” for the doctor – but do it with your mouth closed, 20 times.
Then try this: When you swallow, lift your tongue to the roof of your mouth while keeping the rest of your face relaxed.
Those exercises should reduce snoring.
