Snoring affects 30 million people in the UK. The majority of people, however,  “are unaware of why they snore or what snoring could indicate about their overall health,” according to Jagdeep Bijwadia, a board-certified doctor in internal, sleep and pulmonary diseases medicine.

Snoring can be a telltale sign of an underlying sleep disorder like sleep apnea, a condition that can cause a pause in breathing while asleep. But simple, daily habits or decisions can also make you vulnerable to snoring, Bijwadia added. 

And while people may take snoring lightly, the condition can do more than just keep your bedmate up at night. Recentstudies have shown that snoring can lead to a high risk for hardening of the arteries, a leading cause of stroke, and general cardiac issues, said Steven Olmos, founder of TMJ & Sleep Therapy Centres International.

Fortunately, you can control many cases of snoring. The first step is to figure out what causes it and get the condition treated appropriately. Here are just a few unexpected things that could be behind your unwanted snoring habit.

1. You’re Enjoying An Evening Nightcap 

Having a glass of wine at the end of the day may take the edge off, but it isn’t necessarily doing your sleeping habits any favours. According to Bijwadia, alcohol relaxes your airway muscles, which can lead to excessive snoring ― even if you’re not a regular snorer.

“And the less restorative and deep sleep you get each night, the more it builds and causes you to become more disoriented and foggy throughout the day,” he said.

2. You Have A Nasal Obstruction

Having something blocking off your nasal passageway can definitely contribute to snoring. This could be due to a possible allergy or a deviated septum, according to Brian Drew, a physician at Ear Nose and Throat Specialty Care of Minnesota.

An allergist can help to treat your issues with sensitivities like dust mites or an ENT doctor can help you find an effective way to reduce snoring that occurs because of nasal obstruction.

“Nasal sprays … have been shown to increase nasal volume by 20%, which dramatically increases flow rate,” added Olmos. These products can help alleviate soft tissue swelling due to generalised inflammation and environmental sensitivities.

3. You’re A Back Sleeper

Sleeping on your back may make you much more likely to snore, saidMarcella M. Frank, a sleep medicine specialist at Deborah Heart and Lung Center in Browns Mills, New Jersey.

“When someone sleeps on the back, there is a natural tendency for the jaw and tongue to drop into the back of the throat,” Frank explained. 

According to one study,around 92% of those suffering from sleep-disorder breathing can breathe better when they’re not on their back.

“Sleeping on your side helps to reduce snoring, and for those that suffer from more serious sleep disorders like sleep apnea, it can help alleviate some of those symptoms as well. It can increase your nightly oxygen intake and protects the airway from collapsing,” Bijwadia added. 

4. It May Be Weight Related

Excess body weight can lead topoor muscle tone and an increased amount of tissue around the throat and neck. Both of these can catalyse a snoring condition.

Ensuring you’re active throughout your day will set you up for more quality sleep down the line, Bijwadia said, noting that maintaining a healthy weight may lessen your snoring.

5. Your Thyroid May Be Out Of Wack

“With an under-active thyroid, there may be changes within the upper airway that lead to difficulty breathing during sleep,” saidShoshana Ungerleider, an internist at Sutter Health in San Francisco.

Studies show that hormonal stabilisation in those with a hypothyroid condition improves snoring severity. Some other signs that your thyroid might be low functioning include fatigue, weight gain, dry skin, thinning hair and depression.

6. It Can Be Age Related 

Snoring is more common as we age “simply because of floppy tissue” in the bodies, Frank said.

Exercises like singing, believe it or not, can help with this, Olmos added. Using nasal dilators like Breathe Right strips can also help with age-related snoring.

7. Your Mouth Shape Could Be Causing The Problem

People are all built differently and some of us have amouth anatomy that can make us more prone to snoring. For example, having a lower, thicker or softer palate can narrow your airways and prompt snoring.

Drew noted that some of these structural differences that can lead to snoring can be treated. For instance, custom night guards or mouth appliances might be able to reduce the issue, he said.

8. You’re A Male

Sorry, dudes. Research suggests that physical differences between genders can contribute to snoring. For example, men have narrower air passages that could exacerbate the issue. Men statistically drink more alcohol than women, which can lead to inflammation-induced snoring.

If None Of These Is The Culprit, You May Need To Look Into Sleep Apnoea

Snoring can be a sign of obstructive sleep apnoea, which is a serious medical condition. The condition can cause you to stop breathing throughout the night when you’re asleep because the soft tissues in your throat collapse and block your airway.

“The vibrations of these soft tissues is what causes the snoring noise,” said Kimanh Nguyen, an ENT physician in Beverly Hills.

Symptoms of OSA may include loud snoring, daytime tiredness, morning headaches, restless sleep and periods where you stop breathing or wake up gasping for air. The condition, which can be treated by an ENT doctor or sleep specialist, is diagnosed by a test called a polysomnogram or a sleep study.

If left untreated, it can lead to high blood pressure and cardiac problems. So if none of the above issues seem to be the reason for your snoring, chat with a doctor ASAP.
