Change your sleeping position. Elevating your head four inches may ease breathing and encourage your tongue and jaw to move forward. There are specifically designed pillows available to help prevent snoring by making sure your neck muscles are not crimped.
Sleep on your side instead of your back. Try attaching a tennis ball to the back of a pajama top or T-shirt (you can sew a sock to the back of your top then put a tennis ball inside). If you roll over onto your back, the discomfort of the tennis ball will cause you to turn back onto your side. Alternatively, wedge a pillow stuffed with tennis balls behind your back. After a while, sleeping on your side will become a habit and you can dispense with the tennis balls.
Try an anti-snoring mouth appliance. These devices, which resemble an athlete’s mouth guard, help open your airway by bringing your lower jaw and/or your tongue forward during sleep. While a dentist-made appliance can be expensive, cheaper do-it-yourself kits are also available.
Clear nasal passages. If you have a stuffy nose, rinse sinuses with saline before bed. Using a Neti pot, nasal decongestant, or nasal strips can also help you breathe more easily while sleeping. If you have allergies, reduce dust mites and pet dander in your bedroom or use an allergy medication.
Keep bedroom air moist. Dry air can irritate membranes in the nose and throat, so if swollen nasal tissues are the problem, a humidifier may help.
