Change Your Sleep Position - Lying on your back makes your tongue collapse to the back of your throat. Sleep on your side to help prevent this.
Lose some weight - Gaining weight squeezes the internal diameter of the throat, making it more likely to collapse during sleep.
Avoid Alcohol - Alcohol and sedatives reduce the resting tone of the muscles in the back of your throat, making it more likely you'll snore.
Practice Good Sleep Hygiene - Working long hours without enough sleep makes you sleep hard, causing your throat muscles to become floppier, which creates snoring. Taking a hot shower, using a neti-pot or nasal strips will help with breathing.
Change Your Pillows - Allergens, dust mites, and pet dander can cause allergic reaction that can lead to snoring.
