Benefits of nasal breathing and why it is important.

I found this very interesting article

In the beginning of my practice and throughout the last 3 years, I didn’t know any of these things, theory never interested me in the first place, I am more of a practical person. It is so interesting to know the facts and theory today, I can’t get enough of it.
Here is a short extract from the article :
Here are a few more of the benefits of nasal breathing:

The lungs actually extract oxygen from the air during exhalation, in addition to inhalation. Because the nostrils are smaller than the mouth, air exhaled through the nose creates a back flow of air (and oxygen) into the lungs. And because we exhale more slowly through the nose than we do though the mouth, the lungs have more time to extract oxygen from the air we’ve already taken in.
When there is proper oxygen-carbon dioxide exchange during respiration, the blood will maintain a balanced pH. If carbon dioxide is lost too quickly, as in mouth breathing, oxygen absorption is decreased, which can result in dizziness or even fainting.
Air that we inhale through the nose passes through the nasal mucosa, which stimulates the reflex nerves that control breathing. Mouth breathing bypasses the nasal mucosa and makes regular breathing difficult, which can lead to snoring, breath irregularities and sleep apnea.
Breathing through the nose forces us to slow down until proper breath is trained; therefore, proper nose breathing reduces hypertension and stress. It also helps prevent us from overexerting ourselves during a workout.
Our nostrils and sinuses filter and warm/cool air as it enters our bodies.
Our sinuses produce nitric oxide, which, when carried into the body through the breath, combats harmful bacteria and viruses in our bodies, regulates blood pressure and boosts the immune system.
Mouth breathing accelerates water loss, contributing to dehydration.
The nose houses olfactory bulbs, which are direct extensions of part of the brain called the hypothalamus. The hypothalamus is responsible for many functions in our bodies, particularly those that are automatic, such as heartbeat, blood pressure, thirst, appetite and sleep cycles. The hypothalamus is also responsible for generating chemicals that influence memory and emotion.
The increased oxygen we get through nasal breath increases energy and vitality.
