Your Nose: The Most Underused Organ in Your BodySubmitted by barracuda_trader on Fri, 12/27/2013 - 07:36
Your mouth was designed for eating, not breathing.
Likewise, your nose and sinuses were designed to optimize breathing in ways that may surprise you.
Your upper airways are designed to “pretreat” the air you breathe as it enters your body.
When you breathe through your mouth, many of the things that are supposed to happen don’t, because the air bypasses this part of your respiratory system before it enters your lungs. When you take in air through your nose, the following beneficial processes occur:
Air is warmed and humidified before it hits your lungs.
The cilia, or tiny hairs, lining your nose trap pathogens, dust, and other foreign particles, acting as a pre-filter before the air reaches your lungs.
Nerves in your nasal passages (which connect to your hypothalamus) sense everything about your breathing and use that information to regulate it.
Nitric oxide (NO) is made by your nose and sinus mucous membranes, so when you breathe through your nose, you carry a small amount of this gas into your lungs.
NO is a potent bronchodilator and vasodilator, so it helps lower your blood pressure and significantly increases your lungs’ oxygen-absorbing capacity.
NO also kills bacteria, viruses and other germs, so nose breathing helps keeps you from getting sick.
When you breathe through your mouth, NONE of these functions can take place.
Mouth breathing is analogous to expecting your body to make use of food by bypassing your stomach – it would be missing some critical steps in the digestive process, and the end result would not be good.
