Mouth Breathing vs Nose Breathing
There are many healthy reasons to breathe through your nose, and some serious consequences to mouth-breathing.
“Mouth-breather!” It’s a term people might use as an insult or say as a joke, but breathing through the mouth has some very real, and very serious health consequences. Here’s a partial list:
Mouth breathing can cause bad breath, because of altered bacterial population in the mouth.
Breathing by mouth results dries the tongue, teeth and gums; consequently, levels of acid in the mouth can lead to tooth decay and gum problems.
Another undesirable consequence of mouth breathing, especially when asleep, is dehydration – how often do mouth breathing sleepers awake with a dry mouth?
Sports performance can suffer from mouth breathing; when we inhale and exhale through the mouth, oxygen uptake in the lungs can go down.
Children who breathe through their mouths are at greater risk of abnormal facial structure, head posture, and impaired respiratory strength.
Not only does mouth breathing cause issues such as facial changes, dry mouth and sleep disturbances, but it can also lead to ear infections, airway infections, inflamed sinuses and snoring.
The lack of oxygen into the lungs can cause huge problems for adults, leading to high blood pressure and heart problems.
Other mouth breathing effects include headaches, poor posture (as mouth breathers tend to slump forward to open the airways), gum disease, bad breath and cold and flu like symptoms.
Here are some of the benefits of breathing properly through your nostril:
Nose breathing, especially the resistance to airflow that comes from exhaling through your nose, keeps the air in your lungs a little longer. This can increase the amount of oxygen that enters your bloodstream with each breath as much as 20 per cent.
Much more than your mouth and throat, the nasal passages are designed to warm and humidify the air you inhale. The temperature of your breath can rise more than 40°F on the way from your nose to your lungs. This is especially important in cold weather.
Breathing through the nose helps remove a significant share of germs, irritants and bacteria from each lungful of air you breathe
It's easier to breathe regularly when you inhale and exhale through your nose.
Nitric oxide (NO), which plays an important part in immune response and vasoregulation, is released in the nasal passages, following the air stream to the lungs.
Nose breathing can help fight infections.
Nasal breathing boosts blood circulation, blood oxygen and carbon dioxide levels, slows the breathing rate and improves overall lung volumes.
Nose breathing helps proper oxygen-carbon dioxide exchange during respiration, thereby helping the blood to maintain a balanced PH.
