Breathing through the mouth is a sign of chronic hyperventilation.
It reduces absorption of nitric oxide (a powerful hormone that is generated in
sinuses) and concentration of carbon dioxide in airways and arterial blood
causing cell hypoxia in all vital organs.
Mouth breathing suppresses immune systems and has many other
pathological effects (for medical research quotes follow the links at the bottom
of this web page). Mouth breathing during sleep is one of the two central
factors responsible for highest mortality rates in the severely sick during
early morning hours. Is it possible to stop mouth breathing?
people with a high CP (over 40 or 60 s for the body-oxygen test - or
stress-free breath holding time test done after usual exhalation)
do not breathe through the mouth at all. If they try, their CP will be below
40 s. On the other hand, if you observe sick people,
you will notice that breathing through the mouth frequently occurs. It happens naturally at night as well when the CP is below 20 s.
With over 20 s for the current CP, a person can have nasal breathing, but
partial nose blockage is still possible. With over 30 s CP, breathing through
the nose is easy.
Buteyko Mouth Taping Technique
In the 1960s, Russian patients invented
mouth taping to ensure nasal breathing and stop mouth breathing during
the night. Mouth taping is now a part of the Buteyko breathing method. Read more about
Mouth Taping for better sleep and higher body
oxygen levels in the morning.
Nasal respiration during the day
that for maximum body-oxygen levels, we need to breathe through the nose 24/7, even
during physical exercise (see
Effects of Exercise
on the Respiratory System for more detail). Always slow
down or take 1-2 min rest if you exercise so intensively that you get a strong urge to
open your mouth.
Some older people may use mouth taping during the day, if they have memory
problems or can forget about the role of nasal breathing due to other factors.
If you have family members or friendly co-workers and you want to prevent
mouth-breathing during the day, tell them that your doctor (Dr. Artour Rakhimov)
prescribed you nasal breathing 24/7. Ask them to pay attention to the way you
breathe and remind you about your commitment to solve this problem.
Use stickers on your PC screen, doors, desks, etc. reminding you, "Breathe
only through the nose". Keep a large mirror on your working desk so that you can
see your face and the way you breathe through.
If you have children, promise them a small treat if they catch you breathing
through the mouth.
Your struggle will not be long if you increase your morning CP up to 20 s or
more. Hence, carefully study other Modules so that you can move up to the safe zone
and get busy with more advanced challenges in your life and your Buteyko
