Is it better to breathe fast or slow and either through your mouth or nose
Nose Breathing

Breathing through the nose has many benefits. Breathing through the mouth, many negatives. There are some researchers who believe that mouth breathing and associated hyperventilation causes or exacerbates asthma, high blood pressure, heart disease, and many other medical problems.
Always better whenever possible (deviated septum and small nostrils may make it impractical but still nose breathing 24 hours a day is extremely important for those who desire the longest and most healthy life.

1. The lungs are a primary source of our energy level. They extract oxygen from the air we breathe primarily on the exhale. Because the nostrils are smaller then the mouth, air exhaled through the nose creates back pressure when one exhales. It slows the air escape so the lungs have more time to extract oxygen from them. When there is proper oxygen-carbon dioxide exchange, the blood will maintain a balanced pH. If carbon dioxide is lost too quickly, as in mouth breathing, oxygen absorption is decreased.

2. Afferent stimuli from the nerves that regulate breathing are in the nasal passages. The inhaled air passing through the nasal mucosa carries the stimuli to the reflex nerves that control breathing. Mouth breathing bypasses the nasal mucosa and makes regular breathing difficult. During sleep, it predisposes one to loud snoring and irregular breathing and can lead to a serious condition called Sleep Apnea and heart conditions.

3. Also, when mouth breathing, the brain thinks carbon dioxide is being lost too quickly and sensing this, will stimulate the goblet cells to produce mucous, slow the breathing and cause constriction of blood vessels. Breathing through the nose also limits air intake and forces one to SLOW down. Proper nose breathing reduces hypertension and stress for most people. Kind of like a speed control (governor) on a car engine.

4. The nostrils and sinuses filter and warm the air going into the lungs. The mouth breather bypasses this. The sinuses produce nitric oxide (NO) which is a pollutant but harmful to bacteria in small doses. Nitric (not nitrous) oxide is one of the very important chemical parts of sexual arousal. It vaso-dilates (engorgement) and plays a part in maintaining erection.  (+ info)

What are the causes of mouth breathing leading to extremely dry oral cavity and throat ?

---

Usual reason is blocked or chocked up nostrils but are there other causes for this condition ?
Enlarged adenoids and polyps can cause mouth breathing.  (+ info)

why do u get a sour throat after sleeping while breathing with ur mouth?

---

when i go to sleep and i breath with my mouth, how come when i wake up in the morning i have a sour throat but im not sick?
cuz ur drying out your moth and inside your neck from breathing in and out.

that happened to me last nite :P  (+ info)

Will breathing in insulation cause your mouth to become dry?

---

My son ceiling collapse in his room and insulation was everywhere. I had on open toe shoe when I enter his room to see all the damage. I had to take 3 baths and benadryl to stop from itching. The landlord say it okay to stay there but, everythime I there my mouth get really dry and need to keep clearing my thoart. What should I do?
Breathing in like in you take a breath and you take in insulation? Not a good idea. First of all it is probably dry up there. Second if you are breathing in insulation particles it is likely the lung will not rid itself of all of them and you can cause a mechanical pneumonia as the body see this glass as foreign material and chooses to encapsulate them with mucous. Also they are very sharp and literally can cause bleeding, sometimes uncontrollable, especially if you are on blood thinners. How is it you are not wearing a mask? Just saying because we have all been there. Well we just have to change this light switch in the attic and it will only take a minute I don't need a mask. You could end up in hospital. Not a pretty picture. Now if you just meant you are breathing in an area which has insulation and it is covered than I don't have enough info to make a call.  (+ info)

Breathing through my nose or through my mouth?

---

Is it ok if I sleep while breathing with my mouth open or through my nose?
Nasal breathing is the recommended way for proper respiration. Most methods of breathing exercises suggest to deep breathe thru you nose and exhale thru your mouth. This method allows for adequate carbon dioxide and oxygen exchange.and stores. Besides, the nose can warm the air. It has hairs which can filter the air for any germs or dust particles. Oral breathing can indicate Obstructive Sleep Apnea (OSA)..It can make the mouth very dry. It can cause nasal and sinus congestion.

What are the known negative effects of mouth breathing?
Oral or Mouth breathing can cause morning fatigue; sleep apnea, and snoring. Patients with asthma; patients with COPD and emphysema struggle to breathe and they mostly do oral breathing.

Advantages of nasal breathing:
1) Dead space and airway resistance are found to be significantly greater during nose than during mouth breathing. These results fit our observation that end-tidal PCO2 was significantly higher during nose than during mouth breathing. It is suggested that a loss of nasal functions, such as during nasal obstruction, may result in lowering of CO2, fostering apneic spells during sleep.
Hence, mouth breathing reduces oxygenation of the whole body. There is less oxygen consumption thru oral breathing.

Usually air will enter the respiratory system through the nostrils. The nostrils then lead to open spaces in the nose called the nasal passages. The nasal passages serve as a moistener, a filter, and to warm up the air before it reaches the lungs. The hairs existing within the nostrils prevents various foreign particles from entering.
You will obviously lose this special advantages if you breathe thru your mouth..

2) Cleaning, warming and humidification of inspired air in case of nasal breathing
Our nasal passages are created to clean, humidify and warm the incoming flow of air due to the thin layer of protective mucus. This layer of mucus can trap almost all (95-99%?) dust particles, bacteria, viruses and other airborne objects. This is what long, narrow, and intricate nasal airways are for.

Nasal breathing increases the respiratory system's ability to warm and humidify the inspired air compared to oral breathing and reduces the drying and cooling effects of the increased ventilation during exercise. The major function of the nose is to warm and humidify air before it reaches to the lungs for gas exchange.

3) Autoimmunization effect for nasal breathing

When the mouth is used for inhalation, this air route is shorter, wider and almost straight. Now the same airborne objects can easily get into the alveoli and the blood, creating stress, first of all, for the immune system (detection, marking, isolation, and deactivation of intruders) and then for organs of elimination (kidneys, liver, skin, and GI patches). Some pathogens, can even multiply in the lungs causing more severe problems.

The layer of mucus moves as a carpet from sinuses, bronchi and other surfaces towards the stomach. Hence, these trapped by the mucus objects are drained (or swallowed) into the stomach where digestive enzymes and HCl (low pH) make bacteria and viruses either dead or weak. Further along the digestive conveyor, some of these substances can penetrate into the blood due to intestinal permeability effect. But now these pathogens are either dead or weakened and would not do much harm while providing a good lesson for the immune system. This is exactly how immunization, done by medical personnel, often works with success: medical doctors inject a vaccine with either dead or weakened bacteria or virus to teach and strengthen the immune response to these pathogens. Hence, nasal breathing is a natural mechanism of autoimmunization

If you are an asthmatic and endurance athlete, you should train mostly, or better only using your nose, and for really important competitions mouth-breathing can be used, if you have no problems with your asthma. What is important for training is to have an aerobic training effect. while breathing through the nose.

Oral breathing in asthmatic people is one of the major causes of exercise -induced asthmatic attacks( EIA)

Mouth-breathing in a child can result in a slower mental and physiological development in relation to schoolmates. Mouth breathing, in general, from physiological viewpoint, is unacceptable.

What happens when we breathe through the nose? On the mucosal surface of the nose microbes and viruses die; air is cleaned, warmed to optimum temperature, humidified till the optimum level and, in this ready form, enters the bronchi

Practically, when some household members are sick with for example, flu or cold, the still healthy people can breathe either through the nose teaching his own immune system how to defeat the pathogenic bacteria or virus, or through the mouth allowing the same pathogens to access, settle and multiply in various parts of the human body causing the infection.

4) Utilization of own nitric oxide generated in nasal airways.

Normal nasal breathing helps the body to use its own nitric oxide. This substance is produced, among other places, in nasal passages. During normal breathing, we have quiet prolonged exhalations (that do not prevent accumulation of nitric oxide in some areas of nasal passages) and relatively quick inhalations (that allow inhalation of the accumulated nitric oxide). During hyperventilation exhalations are forceful and quick (as one can observe in many sick people) and inhalations are slow. This reversal of the main stages of breathing decreases the utilization of nitric oxide.

NItrous Oxide can inhibit inflammation of the blood vessels and help in the destruction of parasitic organisms, viruses, and malignant cells by inactivating their respiratory chain enzymes in mitochondria.

Learning, memory, sleeping, feeling pain, and some other processes require NO for transmission of neuronal signals. On the other hand, brain cells can probably be killed during a stroke due to excessive production of nitric oxide.

Abnormal NO production and its availability are now associated with hypertension, heart failure, stroke, obesity, diabetes (both type I and II), atherosclerosis, rheumatism, aging, and dyslipidemias (particularly hypercholesterolemia)

Heart patients, who often breathe through the mouth, may notice that their heart problems have a tendency to appear at such times (when they breathe through the mouth).

Obviously, during mouth breathing it is not possible to utilize own nitric oxide that is synthesized in the sinuses.

5) The mouth is designed by Nature for drinking, eating and speaking. At all other times it should be shut. (Teeth flossing and brushing can be other sensible exceptions.)

6) Nasal breathing provides more resistance to respiratory muscles during breathing as compared to mouth breathing (the mouth-breathing route is shorter and has a larger cross sectional area). Due to an in-built tendency to optimize physiological processes, the human organism is ready, as during nose-breathing, to breathe less and tolerate higher CO2, than to exert more demands on constantly working respiratory muscles

7) Most medical doctors do not know when and how sick people should exercise. It is known that exercise can be useful, but sick people often die or experience heart attacks, exercise-induced asthma attacks,(EIA) and other exacerbations or acute states of their diseases during or after physical exercise. However, when physical exercise is done with strictly nasal breathing (in and out), physical activity is 100% safe even for severely sick people.

8) When the mouth is open: (There is a risk of steaming, Aspiration pneumonitis and deglutition pneumonia) The breathing is given priority and the entrance of the gullet has been blocked when the mouth is opened (Hyoid: hyoid bone falls) and hence the collected saliva flows into the organ

When do babies start breathing through there mouth?

---

Does anyone have a precise answer to this question. We have an appointment this week so I will ask the Pediatrician when I go but maybe someone out there may know. I will come back and answer my own question after the appointment if I don't hear from anyone here.

Regards,
Matt

breathing through mouth or nose better for teeth?

---

i have breathed or watever through my mouth as long as i could remember. i had my tounsils taken out..i had heard that one way is better for your teeth if you have cavitys?? which one is better and how can i teach myself to breath through my nose?
Well, just sometimes cold air can be sensative on your teeth, I don't think it effects it durasticly,

but i breath through my mouth and nose, i would suggest your nose because the air gets filtered better through your nose.

And teaching yourself to breath throguh your nose... Well im positive you know how, because its natural, its just like smelling, just try and monitor your breathing so you get use to it.

Good luck  (+ info)

How can I hide my mouth breathing?

---

I can't breathe through my nose thanks to me breaking a few months back. It looks fine now but I messed something up on thing inside and now I can barely breathe. The doctors said they can fix it but I can't afford it right now.

So its really ugly having your mouth hang open like an idiot, so I was wondering if there are any good ways to hide it. Thanks

Can breathing from mouth cause miscarriage in pregnancy?

---

can enough oxygen reach the baby? I live in a cold country and sometimes my nose gets blocked, is it safe? wht r the cases in which the baby;s heartbeats can stop?
Enough oxygen gets through. Don't worry. If breathing from the mouth caused miscarriages/stillbirths I don't think they're be a population. LOL.  (+ info)

I wake up breathing heavily and sweating with the taste of blood in my mouth. Why would this be?

---

Could this be due to mental issues? I have a past of bulimia and depression.
It's sounds like you might be having nightmares and biting your tongue or the inside of your mouth in your sleep. The nightmares could be a side effect of paranoia that you are unaware of.  (+ info)
