Is snoring dangerous?
1. What is snoring and why do we snore?
Snoring occurs when airflow through the pharynx (the area at the back of the throat) is obstructed. This obstruction causes the soft tissues in the airway to vibrate, producing the characteristic sound known as snoring during sleep.
2. Is snoring dangerous?
Whether snoring is harmless or potentially dangerous depends on its characteristics and any accompanying symptoms.
Primary snoring (simple snoring): If you snore occasionally, such as when you are extremely tired or have nasal congestion, and the snoring is regular and not accompanied by symptoms such as waking up during the night, gasping for air, or daytime sleepiness, it is generally considered benign. This type of snoring primarily affects the sleep quality of those around you.
Snoring as a warning sign of an underlying condition (a sign of sleep apnea): Pay attention if your snoring or that of a family member has any of the following characteristics:
- Very loud snoring
- Sudden pauses in breathing lasting 10 seconds or longer, followed by gasping or snorting as the person attempts to resume breathing
- Waking up suddenly with a choking sensation or shortness of breath
These signs may indicate obstructive sleep apnea (OSA), a serious condition in which the airway partially or completely collapses during sleep, temporarily reducing oxygen supply to the brain and body.
Over time, OSA can increase the risk of cardiovascular disease, high blood pressure, and stroke. It can also cause fatigue and excessive daytime sleepiness.
3. Causes and risk factors for snoring
Several factors can make the airway more likely to narrow during sleep, including:
- Weight gain
- Enlarged tonsils or adenoids
- Endocrine disorders
- Genetic syndromes
- Use of sedatives or alcohol
- Nasal congestion
- A small jaw
- Pregnancy
- Postmenopausal status
Another common cause of snoring is sleeping on your back, which can affect breathing by narrowing the upper airway. People who snore are often encouraged to sleep on their sides.
4. When should you see a doctor about snoring?
You or a family member should consult a respiratory medicine, sleep medicine, or ear, nose, and throat (ENT) specialist if snoring is accompanied by any of the following signs:
- Very loud snoring that can be heard from another room
- Pauses in breathing during sleep, as described by a bed partner who notices a period of silence followed by gasping or snorting
- Waking up suddenly with a choking sensation or shortness of breath
- Excessive daytime sleepiness, including falling asleep easily while driving, attending meetings, or working
- Morning headaches, difficulty concentrating, or increased irritability
- High blood pressure
The doctor will examine your upper airway and may recommend polysomnography (PSG), a sleep study that records various aspects of your sleep, to establish an accurate diagnosis.
Do not dismiss your snoring. Pay attention to your body and the observations of your family members. Good sleep is the foundation of good health and a better quality of life.
