Because it really hurts...just use a trimmer
If you are talking about the structure just underneath the interior division of the nose, it's called the columella.
Boogers typically form when the lining of your nose traps dust, germs, and other particles. This process can happen relatively quickly, within minutes to hours, depending on the environment and air quality.
You should especially inhale through the nose when it is cold. Cold air damages the fragile linings of the respiratory tract. Blood vessels in the nasal cavity warm inhaled air to reduce the damage caused. If you breathe through the mouth, air is not warmed, leaving you at risk of catching chest infections such as pneumonia. If possible, breathe out through the nose as well, but it doesn't matter so much if you exhale through the mouth, because the exhaled air has already been warmed in your body.
The nose filters, warms, and moistens the air you breathe. Hairs and mucus in the nose trap particles and pathogens, while blood vessels help warm and humidify the air before it reaches the lungs.
Yes they can pull across an air gap and air is gases
The nose leads to the nasal cavity, which is a passageway for air to enter the respiratory system. Within the nasal cavity, the air is warmed, filtered, and humidified before traveling further into the lungs.
By expanding them, you create a vacuum inside them; given a portal (your mouth, nose), the vacuum will pull the ambient air in, just as a vacuum cleaner pulls things inside by creating a vacuum.
Dry air, possibly, but being physically dehydrated should not induce nose bleeds.
Why not, it can pull warm air into the room.
Fans should push air through the radiator. This is because pushing air through the radiator into the case helps to expel hot air faster and more effectively, which can improve overall cooling performance.
Within the nasal cavity are epithelial lined boney projections called conchae or turbinates. These structure heat and humidify the air that is drawn into the lungs as well as creating tubulance all of which make the air cause less damage to the respiratory tract.
During the dive your nose will want to naturally breath in, or take in water so having the nose under the mask helps that NOT to happen. Also if you take on water inside your mask and your nose is not within it will be VERY difficult for you to empty the water. To empty water from your scuba mask at depth you simply pull it out from your face and breath out through your nose and this causes the water to pour out. How would you do this if your nose is not enclosed within the mask? And also so that water doesn't go up your nose. And mouth (it doesn't taste good).
The medical term is "paranasal sinuses." These are air-filled cavities located within the bones surrounding the nasal cavity. They are important for natural drainage and humidifying the air we breathe.
Why would you want to? the only thing you should concentrate on sniffing up your nose is Fresh Air. Eat the Candy!
The fine nose hair and the mucus. The mucus moist the air and the nose hair traps the dust and cleans the air.
you don't breath in air with the help of your nose the time.
The sinuses are paired air pockets located within the bones of the face. They are: the ethmoid sinuses; located between the eyes, just behind the bridge of the nose.
