Why do snoring happens? How do we get rid of it?

Question

Snoring happens when you can't move air freely through your nose and throat during sleep. This makes the surrounding tissues vibrate, which produces the familiar snoring sound. People who snore often have too much throat and nasal tissue or ?floppy? tissue that is more prone to vibrate.There are so many bizarre anti-snoring devices available on the market today, with more being added all the time, that finding the right solution for your snoring can seem like a daunting task. Unfortunately, many of these devices are not backed up by research, or they work by simply keeping you awake at night. There are, however, plenty of proven techniques that can help eliminate snoring. Not every remedy is right for every person, though, so it may require some patience, some lifestyle changes, and a willingness to experiment with different solutions.

Lifestyle changes to stop snoring

Lose weight. If you?re overweight, dropping even a few pounds can reduce fatty tissue in the back of the throat and decrease or even stop snoring. 
Exercise can also help to stop snoring. As well aiding weight loss, exercising your arms, legs, and abs, for example, also leads to toning the muscles in your throat, which in turn can lead to less snoring. There are also specific exercises you can do to strengthen the muscles in your throat (see below).
Quit smoking. Quitting is easier said than done, but smoking irritates the membranes in the nose and throat which can block the airways and cause snoring. Get help with quitting here.
Avoid alcohol, sleeping pills, and sedatives because they relax the muscles in the throat and interfere with breathing. Talk to your doctor about any prescription medications you?re taking, as some encourage a deeper level of sleep which can make snoring worse.
Establish regular sleep patterns. Create a healthy bedtime ritual with your partner and stick to it. Hitting the sack in a routine way together can help you sleep better and often minimize snoring.
Bedtime remedies to help you stop snoring

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.
Change your sleeping position. Elevating your head four inches may ease breathing and encourage your tongue and jaw to move forward. There are specially 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 often resemble an athlete?s mouth guard and 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.
Throat exercises to stop snoring

Practiced daily, throat exercises can strengthen muscles in the upper respiratory tract and be an effective way to reduce or stop snoring.

Try the following exercises to stop snoring. Start slow and gradually increase the number of sets you do. In some cases, you may be able to combine the exercises with other activities, such as commuting to work, housework, walking your dog, or taking a shower.

Repeat each vowel (a-e-i-o-u) out loud for three minutes a few times a day.
Place the tip of your tongue behind your top front teeth. Slide your tongue backwards for three minutes a day.
Close your mouth and purse your lips. Hold for 30 seconds.
With mouth open, move jaw to the right and hold for 30 seconds. Repeat on left side.
With mouth open, contract the muscle at the back of your throat repeatedly for 30 seconds. Tip: Look in the mirror to see the uvula (?the hanging ball?) move up and down.
