The professionals have spoken, and the research is clear, nose breathing is the correct and most optimal way to breathe.
Not only are our bodies designed for nose breathing based on the specific apparatus and the mechanisms by which we inhale and exhale through nose breathing, but there are numerous health benefits to be had from correct consistent nose breathing.
The converse is also true; because mouth breathing bypasses important stages in the breathing process, this way of breathing leads to many health problems, not the least of which may include snoring and sleep apnea.
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. It even makes some folks look dull witted or slightly unconscious! Chronic mouth breathing may cause the muscles that open the sidewalls of the nose to weaken.
Close to 80 percent of the Western population breathes incorrectly with habits such as shallow breathing, breathing through your mouth instead of your nose, using the upper chest, and having noticeable breathing during rest.
Your nose is the only organ able to properly prepare the air you breathe; mouth breathing leads to over-breathing, chronic hyperventilation, depleted carbon dioxide levels, reduced blood circulation, buildup of toxins and narrowing of the airways.
Mouth breathing and resultant over-breathing elevates your blood pressure and heart rate and worsens asthma, allergies, rhinitis, sleep apnea, and deprives your heart, brain and other organs of optimal oxygenation.
Overbreathing and hyperventilation during exercise can lead to reduced performance, and can also cause vasoconstriction, which increases your risk for arrhythmias and heart problems, even if you have none of the usual cardiac risk factors.
If you are still not convinced that nose breathing is better, here are some facts for you:
The nostrils and sinuses filter and warm the air going into the lungs. 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 (engorges) and plays a part in maintaining erection.
Each nostril is innervated by five cranial nerves from a different side of the brain. Each nostril functions independently and synergistically in filtering, warming, moisturizing, dehumidifying, and smelling the air.
Always better whenever possible; nose breathing 24 hours a day is extremely important for those who desire the longest and most healthy life.
