Over the years, you have probably been told countless reasons why you should quit smoking cigarettes, but can another reason be that smoking can cause snoring and sleep apnea? Learn facts about this potential relationship and whether it might be contributing to disrupted breathing in sleep.

The Relationship Between Smoking and Snoring

It seems logical that smoking may increase your risk of snoring. The irritating smoke from cigarettes, cigars, and pipe tobacco may cause inflammation along the tissues (or mucosa) that line the airway.

This may lead to swelling and narrowing. As the airway narrows, airflow may move more turbulently. This disruption of your upper airway, especially your nasal passage and throat, may have other consequences. It may cause increased airway congestion. The turbulent airflow may lead to vibration as air moves through, leading to the unpleasant sound of snoring.

Large research studies actually support these proposed associations. In one study of 811 adults, the risk of snoring was 2.3 times greater among current smokers. In another large study of 15,555 people, snoring occurred more commonly among current smokers (24 percent) compared to former smokers (20 percent) and never smokers (14 percent).

What Is Your Risk of Snoring and Sleep Apnea with Smoking?

The risk of snoring seems to correlate with the amount of smoking. In other words, if you smoke more heavily, the risk of snoring is likewise increased.

Someone who smokes 2 packs of cigarettes per day has a much higher risk compared to someone who smokes only a few cigarettes on the weekend. 

It is uncertain if this increased airway resistance can lead to a collapse of the airway called sleep apnea. It is likely that it would contribute, but other factors may also play a role.

Moreover, the contribution of nicotine withdrawal or nasal congestion in this phenomenon is not fully understood.

Nevertheless, if you smoke, snoring may be another reason for you to finally quit.
