Don’t let snoring ruin your good night’s sleep. Learn what causes snoring and how you can cure it.
What causes snoring?
Just about everyone snores occasionally, and it’s usually not something to worry about. 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. The position of your tongue can also get in the way of smooth breathing.

If you regularly snore at night it can disrupt the quality of your sleep—leading to daytime fatigue, irritability, and increased health problems. And if your snoring keeps your partner awake, it can create major relationship problems too. Thankfully, sleeping in separate bedrooms isn’t the only remedy for snoring. There are many effective solutions that can help both you and your partner sleep better at night and overcome the relationship problems caused when one person snores.

Since people snore for different reasons, it’s important to understand the causes behind your snoring. Once you understand why you snore, you can find the right solutions to a quieter, deeper sleep—for both you and your partner.

Common causes of snoring
Age. As you reach middle age and beyond, your throat becomes narrower, and the muscle tone in your throat decreases. While you can’t do anything about growing older, lifestyle changes, new bedtime routines, and throat exercises can all help to prevent snoring.

Being overweight or out of shape. Fatty tissue and poor muscle tone contribute to snoring. Even if you’re not overweight in general, carrying excess weight just around your neck or throat can cause snoring. Exercising and losing weight can sometimes be all it takes to end your snoring.

The way you’re built. Men have narrower air passages than women and are more likely to snore. A narrow throat, a cleft palate, enlarged adenoids, and other physical attributes that contribute to snoring are often hereditary. Again, while you have no control over your build or gender, you can control your snoring with the right lifestyle changes, bedtime routines, and throat exercises.

Nasal and sinus problems. Blocked airways or a stuffy nose make inhalation difficult and create a vacuum in the throat, leading to snoring.

Smoking, and medications. Alcohol intake, smoking, and certain medications, such as tranquilizers like lorazepam (Ativan) and diazepam (Valium), can increase muscle relaxation leading to more snoring.

Sleep posture. Sleeping flat on your back causes the flesh of your throat to relax and block the airway. Changing your sleep position can help.

Ruling out more serious causes
Snoring could indicate sleep apnea, a serious sleep disorder where your breathing is briefly interrupted many times each night. Normal snoring doesn’t interfere with the quality of your sleep as much as sleep apnea, so if you’re suffering from extreme fatigue and sleepiness during the day, it could be an indication of sleep apnea or another sleep-related breathing problem. Call your doctor if you or your sleep partner have noticed any of the following red flags:

You snore loudly and heavily and are tired during the day.
You stop breathing, gasp, or choke during sleep.
You fall asleep at inappropriate times, such as during a conversation or a meal.
Linking the cause of your snoring to the cure
Monitoring your snoring for patterns can often help you pinpoint the reasons why you snore, what makes it worse, and how to go about stopping it. To identify important patterns, it helps to keep a sleep diary. If you have a sleep partner, they can help you fill it in. If you sleep alone, set up a camera to record yourself at night.
