Estimates vary, but many sources suggest 25% to 50% of adults are habitual mouth breathers, especially during sleep, though some surveys show higher self-identification (around 61%). While nose breathing is ideal, mouth breathing is common, particularly at night, potentially affecting sleep, dental health, and overall well-being.
If you're a mouth breather, you're not alone. While studies differ on just how many people are breathing through their mouth regularly (as opposed to their nose), in one survey, nearly 61% of people identified themselves as such. Studies estimate anywhere from 11% to 56% of children are mouth breathers.
Mouth Breathing vs Nose Breathing
Mouth breathing is a common condition that can have serious health consequences. Although mouth breathing is often considered normal, it can shorten your life by a decade or more. Mouth breathing occurs when the nose cannot adequately filter and humidify the air.
It's most often used to knock someone down a peg, but what most don't know is that anyone can be a "mouth breather" if there is an obstruction to the nasal airway. If untreated, breathing through the oral cavity can cause a myriad of other health issues so there's a reason why it has such a bad rap.
Breathing through your mouth can actually be the cause of your cold or sickness. When we breathe through our mouths, the air that we breathe tends to be dry and cold air. This air can irritate our airways, making them more susceptible to infection. This could be why you wake up with a mild sore throat in the morning.
The relationship is both direct and indirect: Direct Effects: Poor sleep quality from mouth breathing leads to symptoms that mirror ADHD, including inattention, hyperactivity, and impulsivity. Children who don't get quality sleep struggle with executive function—the brain's ability to plan, focus, and control behavior.
Breathing through your mouth occasionally, like when you're congested or exercising intensely, isn't necessarily harmful. However, habitual mouth breathing, especially during sleep, can lead to serious issues over time. Some of the problems linked to long-term mouth breathing include: Dry mouth and sore throat.
Moreover, mouth breathing can affect your facial structure over time, leading to what's known as 'mouth breather face', characterized by a droopy, less attractive appearance.
Highlights. Sleep hypopnea is defined as a drop of ≥30% in breathing amplitude and in oxygen saturation >3% (AASMedicine), or >4% (CMMS). This study reveals a systematic bias, with the 3% criterion consistently yielding higher apnea/hypopnea index values.
Common symptoms include:
It is concluded that the chronic mouth breathing would lead to a lowered IQ comparing with the control group. Some of the most common causes of mouth breathing due to nasal or nasopharyngeal obstruction are adenoid hypertrophy and allergic rhinitis. The treatments of both of etiologies are easily accessible.
1. VO2 Max: Your Cardiovascular Fitness Level. VO2 max measures how efficiently your body uses oxygen during exercise and is one of the strongest indicators of longevity. A higher VO2 max is associated with better heart health, improved endurance, and a lower risk of cardiovascular disease.
Thin individuals can also snore, often due to other factors such as nasal congestion, alcohol consumption, sleep position, or anatomical peculiarities like a thick or long uvula or a deviated septum. These factors can contribute to airway obstruction regardless of body weight.
Active breathing practices, such as pursed-lip breathing and yoga, can help prevent mouth breathing by strengthening the muscles around the nose. This allows the nose to stay open more easily and makes it less likely for mouth breathing to occur.
Like many sufferers, Shaq was unaware that he had sleep apnea until his partner told him about his pattern of snoring and gasping for breath. After completing a sleep study and being diagnosed with moderate sleep apnea, Shaq was fitted with a CPAP mask to get a better night's rest.
The amount of time that a sleep apnea patient stops breathing can be from 10 seconds to two minutes or more. These breathing "stoppages" can happen a few times per hour or, in more severe cases, 60-100 times per hour or to the point where someone spends more time NOT breathing than they are breathing.
Early treatments, even from the age of three, can prevent many future issues. But if you discover this later in life, you can still improve your health. Think of it like exercise: it's never too late to start moving and see positive changes. The same goes for your jaw development and breathing.
Leah Totton, cosmetic doctor and medical director at Dr. Leah Clinic. “Chronic mouth breathing can affect posture, such as a retruded chin, but you will need to seek professional treatment to resolve this. Mouth taping will not directly alter the shape of the jawline, especially with short-term use.”
A major one is lower oxygen levels. When we breathe through our noses, we trigger nitric oxygen production, which helps our lungs absorb oxygen. Mouth breathing skips this process, making it harder to get the most out of each breath, resulting in less oxygen absorbed and less energy for mental and physical tasks.
If you notice that you or your child often breathes through the mouth, it's important to address it early. A dentist or pediatric dentist can check for signs of mouth-breathing during exams, such as dry gums, crowding, or an arched palate.
It can impact energy levels and concentration and can even cause bad breath. Research shows that when we breathe through our mouths, there is an increase in oxygen in the prefrontal cortex of the brain. This part of the brain affects personality expression, decision making and social behaviour.
English lexicographer Jonathon Green notes that by 1915, the phrase "mouth-breather" had developed a pejorative connotation within English slang, defined as a "stupid person". Currently, the Macmillan Dictionary defines the term "mouth breather" as a pejorative noun that is used to mean "a stupid person".
