When you stop nose
breathing and your mouth is open, you suffer from deficiencies in
(oxygen), CO2 (carbon dioxide), and NO (nitric oxide) in body cells due to
This leads to:
- decreased perfusion (blood supply) of all vital organs
- suppressed Bohr effect
- over-excited state of nerve cells causing increased anxiety, more problems
with sleep, etc.
- constrictions of airways, leading to dyspnea, nasal congestion, and frequent
- muscular tension
- tissue hypoxia
- generation of free radicals in body cells
- increased inflammation and heart rate
- abnormalities related to regulation of the blood pressure, blood glucose
levels, and body weight
- suppressed repair of cells, tissues and organs; and so forth.

Stop-mouth-breathing treatment works if you know the cause
Regardless of the superficial causes and triggers, there is
one cause of mouth breathing: chronic hyperventilation.
Hyperventilation leads to the primary effects outlined above. These effects produce
secondary symptoms of hyperventilation such as sinusitis, extra-mucus
production, enlarged tonsils and adenoids, deviated septum, snoring, sleep
apnea, and other pathologies that worsen nasal breathing, creating an illusion
that they cause mouth breathing. Hence, in order to stop mouth breathing, one
needs to stop his or her hyperventilation and increase body-oxygen levels.
Mouth breathing treatment options are numerous. Depending on the
current clinical picture and symptoms, the effective treatment for
mouth breathing includes immediate respiratory techniques and long-term
breathing exercises and lifestyle
changes in order to retrain the automatic breathing pattern.
Mouth-breathing treatment options
- If you suffer from occasional sinusitis (nasal congestion, blocked
nose, or stuffy nose), apply the technique How to Unblock the Nose
Breathing Exercise. It works in 1-2 minutes and this exercise can be
applied as many times as you like. (By the way, this exercise
instantly proves that heavy breathing, which is the cause of your mouth
breathing and nasal congestions since CO2 does wonders as an instant
and long-term mouth breathing
- If you suffer from mouth breathing during sleep, learn the
medical technique How to Tape the
Mouth at Night for stopping oral breathing during night sleep. Note that for
most people it is impossible to stop mouth breathing, if they sleep on
their back at night. Sleeping on your back increases chances of mouth
breathing some 5-10 times. For this reason, if you sleep on your back,
it is also important to apply the treatment
Prevent Sleeping on One's
- If you are afraid or nervous to use a tape at night, you may tape only
one half of your mouth, or you may use 2 clean cotton socks and sew them
together to make a support for your jaw. Sleeping in a sitting position is
another excellent option to feel better in the morning and have higher
morning body-oxygen test results.
- If you suffer from memory problems and your mouth opens automatically (you are a
habitual mouth breather), learn about steps related to constant reminding about
importance of nasal breathing. Use stickers on your tables and desks, PC screen,
doors, and other places on the house reminding you, "Nose breathing!" or "Close
the mouth". Keep a large mirror on your working desk in front of you so that you
can see your face and the way you breathe. If you have children, promise them a
treat if they notice you breathing through the mouth.
- If you are a chronic mouth breather (due to adenoid vegetation, nasal
polyps, deviated septum, and other causes), a simple
and effective way to acquire nasal breathing fast and all the
time is to apply Buteyko reduced breathing exercises.
However, there are better and faster options than Buteyko even people with
sleep apnea, snoring at night with mouth breathing, obesity, hypertension, asthma
and diabetes. These 2 options are provided below as your bonus content.
In general, your chance of success for this
(stop mouth breathing
treatment) program depends on your unconscious or automatic breathing
pattern in the following manner.
