Not much harm can happen if you breathe dust. Unless you have breathing problems such as Asthma. If you have no respiratory problems, the worst that can happen from breathing dust is sneezing or minor coughing
When you breathe in through your nose, lots of tiny pieces of dust come inside along with the air. Some of the dust is stopped by the hairs in your nostrils, but much of it passes further inside. Most of the inside of your nose is lined with a special membrane that makes a sticky liquid called mucus. As the dust is pulled through your nasal passages, it gets stuck in the mucus. Normally, the mucus and dust is moved toward the back of your nose by millions of extremely tiny hairs called cilia, and you swallow it. But sometimes, too much dust gets caught in the mucus, and it irritates the lining of your nose. At that point, you feel a big tickle in your nose, and your sneeze reflex is triggered. You quickly take in a big breath, filling your lungs. Then, your chest muscles compress the air, causing it to forcefully blast out of your mouth and nose, expelling thousands of droplets of saliva and mucus, and with it, the dust that made you sneeze.
When you are in a dusty place, you do tend to cough and sneeze more often. That is because the dust particles get breathed into your nose and throat and caught in the mucus lining, on nose hairs, and cilia in your lungs. When dust is in your nose, it can irritate your nose's lining. This causes you to sneeze, in an effort to clear the dust from your nose. A cough works the same way, but it clears your throat and lungs. Special Caution: Be sure to cover your cough or sneeze with a tissue and then throw it away. Or, if no tissue is at hand, cover your nose and mouth with your arm and sleeve by turning your face into the crook of your elbow. Wash your hands afterward.
Well, there is dust everywhere, so much that people cannot even breathe, so of course it would pollute the air.
You inhale 1 pound every month about. And 14 pounds of dust every 9-12 months. Dust is made of dead skin and hair and particles.
From what I understand, coughs and sneezes aren't directly triggered by cilia. But, if they get overwhelmed, then it could lead to a sneeze or cough. An example- You're in a very dust room. Lots of dust is going into your nose. Your cilia beat a layer of mucus to the back of your nose, which takes about 15 minutes or so, to clear it out. But since there's so much dust, the cilia can't clear enough of it out to keep it from building up in your nose, and this buildup can then irritate the nerves in the lining of your nose. You then sneeze, which uses a big blast of air to expel the dust from your nose and other airways.
In high concentrations - no. In low concentrations it's pretty much like any other dust.
mucus is made by being sick. for example if u breath to much dirt and dust u sneeze and as u sneeze usually mucus comes up.(only if your sick or if getting sick) its also made of cells fiting so its dead cells and alive cells (mostly dead)
It's much better to let yourself sneeze. You sneeze because there's something inside your nose that isn't supposed to be there. When you sneeze, the air blasts out whatever was bothering your nose. Also, the pressure from holding in a sneeze could hurt your ears.
You may have allergies if you sneeze that much at once. It can depend on the situation and the triggers. Pay attention to where and when you sneeze, and you can also consult a doctor if the problem persists.
You need to wear a dust/mist respirator to prevent breathing in the dust. Powder coating powders have low or no VOCs (Volatile Organic Compounds) So it is much healthier than breathing in liquid paint fumes. If you don't breathe in the dust (use a dust mask) there are no known ill effects.
pretty much no one!
