Sleep is vital for childhood development, so it’s no surprise that many parents worry if they hear their child snoring.
Even though snoring is most common among older adults, it occurs in many children as well. It can have many causes, some of which cause snoring to come and go and others that are potentially long-lasting.
Snoring in children is often of little concern, especially if it only happens every once in a while. But if snoring is frequent or severe, it may signal a problem of disturbed breathing during sleep.
Knowing more about the types, causes, consequences, and treatments of snoring in children can allow parents to best look out for the health of their children and help kids get better, more restorative sleep.
Not all snoring in children is the same. The frequency, severity, and impact of snoring in children can vary significantly.
Almost anyone, adults or children, has an occasional episode of snoring. Most of the time, this snoring is minor and short-lived with no measurable effect on the person’s sleep or overall health.
When snoring becomes more frequent and interrupts sleep, it can indicate the presence of sleep-disordered breathing (SDB). Sleep-disordered breathing ranges in seriousness.
On one end is primary snoring, also known as simple snoring or habitual snoring, when a child snores more than two times per week but does not have other noticeable symptoms or associated health issues.
On the other end is obstructive sleep apnea (OSA), a condition marked by constant lapses in a child’s breath during the night. Those lapses, called apneas, occur dozens of times per night when the airway becomes blocked. OSA can cause fragmented sleep and is connected with negative impacts on physical health, mental health, learning, and behavior.
Minor, occasional snoring is believed to occur in up to 27% of children. This type of light, temporary snoring does not usually raise health concerns.
It is hard to determine exact statistics for snoring and sleep apnea. Parents may not always observe their child’s snoring or be aware of its frequency and severity. In addition, detailed testing for sleep apnea, known as polysomnography, may not be available, affordable, or practical in all cases.
Snoring happens when air cannot flow freely through the airway at the back of the throat. As a person inhales or exhales, tissue around the airway vibrates, creating an audible noise.
Multiple factors can create blockages of the airway and cause a person to snore. In children, the most common risk factors for snoring include:
Obstructive sleep apnea is another important risk factor for childhood snoring. It is typical for children with obstructive sleep apnea to snore, including with gasp-like pauses in breath. While most children with OSA snore, not all children who snore have OSA.
Infrequent snoring in children is not usually dangerous, but regular or severe snoring that is indicative of sleep-disordered breathing can have significant health consequences.
Of the greatest concern is obstructive sleep apnea. OSA causes major sleep disturbances and affects the amount of oxygen a child receives during sleep. It has been connected to impaired brain development, reduced academic performance, cardiovascular issues like high blood pressure, altered metabolism, and behavior problems.
On the whole, it is clear that OSA can seriously affect a child’s quality of life. The impacts of OSA have been studied primarily in older children, but researchers believe that they also extend to young kids, such as 2-3 year-olds.
Traditionally, primary snoring that did not rise to the level of OSA was thought of as benign, but recent research has indicated that habitual snoring also carries health risks. Issues of cognitive impairment and behavior problems have been found to occur more in children with primary snoring than in those who never or rarely snore. Regular snoring may affect the nervous system and have negative effects on cardiovascular health.
Though studies have found a link between habitual snoring and health problems, the exact explanation is unclear. It may be that sleep-disordered breathing, even when it is not OSA, can cause small disturbances that affect sleep quality. Further research is necessary to better understand the ways that primary snoring affects children of different ages.
Beyond the immediate health effects, snoring can also be disruptive to the sleep of parents or to siblings who share a room with a child who snores. If the snoring is especially loud, it may cause others to wake up, leading to more fragmented sleep for others in a child’s family.
Parents who are worried about their child’s snoring should talk with a pediatrician. Though some snoring can be normal, various signs can indicate the possibility of sleep-disordered breathing:
Other issues that arise along with snoring may raise further concern:
It is important to note that these factors can be indicators of SDB, but not all children who snore and have these issues necessarily have a more serious breathing condition.
Light, infrequent snoring usually goes away quickly on its own. Even habitual snoring can resolve on its own without treatment for many children. However, in many cases, taking steps to prevent sleep-disordered breathing is important for a child’s health.
A first step in reducing snoring in children is to bring up the issue with their doctor. Many pediatricians will proactively ask about snoring, and parents should be open about their concerns.
A doctor can look for signs of more serious sleep-disordered breathing or other factors, such as asthma or allergies, that could be contributing to snoring. They may recommend additional testing, such as with an overnight sleep study, to look for obstructive sleep apnea.
A clear diagnosis can help determine the best way to decrease snoring, and the doctor will be in the best position to discuss the benefits and downsides of different treatment options.
Surgery to remove the tonsils and adenoids, known as adenotonsillectomy, is one of the main treatments for children with sleep-disordered breathing. It is most often considered for children with severe sleep apnea, but it may be an option for some with primary snoring. By eliminating the tissue that most frequently blocks the airway, this surgery can reduce snoring and pauses in breathing at night.
A positive airway pressure (PAP) device channels pressurized air through a mask and into the mouth and airway to prevent obstruction. Most PAP devices are either continuous (CPAP) or bi-level (BiPAP) based on how they control the flow of air.
While PAP devices are common for treating OSA in adults, in children they are usually reserved for OSA that persists after surgery to remove the tonsils and adenoids.
A way of helping children sleep better is by taking steps to improve their sleep hygiene, which includes their sleep-related habits and environment. Examples of sleep hygiene improvements include setting a consistent sleep schedule, reducing light exposure and screen time before bed, and setting up their bedroom to be as quiet and comfortable as possible.
While these steps for snoring in children are more like home remedies than medical treatments, they may be beneficial. For children who snore, poor sleep hygiene may exacerbate the risk of fragmented sleep and corresponding problems related to behavior, thinking, and health.
