Change your sleeping position, sleeping on sides may help rather than lying on back.
Avoid alcohol, alcohol and sedatives reduce the resting tone of the muscles in the back of your throat, making it more likely to you to snore.
Practice good hygiene in sleep.
Open nasal passages, if snoring starts in your nose, keeping nasal passages open may help. It allows air to move through slower.
Change your pillows often. Allergens in your bedrooms and in your pillows may contribute to snoring.
Stay well hydrated, drink plenty of fluids which help to reduce snoring.
