How do we know about the air we breathe is clean and healthy?
To some extent, we rely on our own minds. For example, we sometimes see large particulate pollutants in the air with the naked eye when the sun shines through the windows. Polluted air often feels trapped because the nose is fantastic to register multiple contaminants at very low levels. Some of these pollutants are filtered out in the nose and upper respiratory passages, but this is far from all pollution; the rest goes into the lungs. Some particles are so small that they pass the lung tissue and are absorbed directly by the blood.
Asthma and poor air quality in homes
People with asthma can have their symptoms worsened sharply in connection with the stay in buildings with poor air quality. Many of the symptoms can be naturally also caused by other than the bad air, but studies show that symptoms occur more often in buildings with poor air quality.

Warm air is often perceived as stuffy and poor!
