Breathing is something we do around twenty thousand times a day, yet most of us never question whether we inhale through the nose or the mouth. Studies show that nose breathing filters, humidifies, and warms the inhaled air, while habitual mouth breathing can dry tissues and disturb sleep. Understanding nose breathing vs mouth breathing is therefore vital for energy, immunity, and even facial growth. This guide compares the two patterns, explains what causes chronic sneezing, and shares expert advice on how to avoid mouth breathing for adults and children. In addition, you will learn when to visit an ENT clinic in Dubai for help with snoring, sleep apnea, or persistent congestion.
Why nasal breathing is the nature’s design
Nasal passages are lined with tiny hairs called cilia that trap dust, pollen, and microbes before they reach the lungs. Turbinates within the nose swirl the air, allowing nitric oxide produced in the sinuses to mix in and widen blood vessels for better oxygen delivery. In contrast, air sucked directly through the mouth bypasses these safeguards, arrives cold and dry, and forces the chest to work harder. A 2024 review in the Journal of Otolaryngology found that consistent nose breathing improves heart rate variability and lowers blood pressure in as little as six weeks.
Health risks linked to mouth breathing
Short-term mouth breathing may occur during a cold, but long-term reliance changes anatomy and physiology. Dry mouth raises tooth decay by 40 percent, says the American Dental Association. Mouth breathing is linked to snoring and sleep apnea too. Because the tongue rests low in the oral cavity, children who breathe through the mouth develop narrow dental arches and the elongated facial shape known as adenoid facies. At Ascent ENT, the best ENT hospital in Dubai, our specialists identify and treat the root causes of mouth breathing with advanced diagnostics and customized care plans to restore healthy nasal function and prevent long-term complications.
Common reasons people switch to mouth breathing
Blocked nasal airflow is the main driver! Seasonal allergies, deviated septum, enlarged adenoids, chronic sinusitis, and habitual overuse of decongestant sprays can all force the body to find an easier path to breathe. Frequent upper-airway infection may also irritate the turbinates and create nonstop irritation that manifests as constant sniffing or what causes chronic sneezing in many adults. In children, thumb sucking and prolonged pacifier use keep the lips open, training muscles to rest in an unhealthy position. When these factors persist, the brain soon registers mouth inhalation as normal, even after the original obstruction clears.
Nose breathing vs mouth breathing in children
Because jaw growth plates close by age twelve, early detection matters. Research from the European Journal of Pediatrics shows that switching a child from mouth to nose breathing within two years can normalize craniofacial development. Warning signs include noisy sleep, daytime fatigue, open-lip posture, forward head tilt, and frequent ENT infections. If you notice these symptoms, schedule an evaluation with the Ascent ENT Speciality Centre to rule out enlarged adenoids, tonsillar hypertrophy, or allergic rhinitis.
Practical strategies: how to avoid mouth breathing
The good news is that most people can relearn healthy nasal breathing with a mix of habit training, environmental changes, and medical support. Try the following science-backed steps:
- Practice diaphragmatic breathing for five minutes twice daily; place one hand on the belly and feel it rise through each nose breath.
- Use saline irrigation or a prescribed steroid spray to reduce nasal swelling before bed.
- Keep humidity between forty and sixty percent to stop mucous membranes from drying.
- Tape the lips gently with medical paper tape at night, a method endorsed by sleep physicians, once an ENT has confirmed the airway is clear.
- If congestion persists longer than three months, book adenoids treatment in Dubai or evaluation for a deviated septum.
Parents wondering how to stop mouth breathing in child patients should add myofunctional tongue exercises, limit screen time that encourages slumped posture, and seek early advice on adenoid facies treatment.
