A host of other inflight ailments have been linked to the conditions within the aircraft. Air pressure is not the only element of concern. Breathe deeply. If the air doesn't seem fresh, it is because it probably isn't. On a long flight one can expect to breathe in some re-circulated air. It is because of this that in the case of when an aggressive airborne disease is discovered to have been carried by a passenger, government health agencies will often become involved. Not only can the air quality of re-circulated air serve to help transmit such diseases, but the enclosed cabin can act as an incubator for disease.

The less threatening aspect of the air inside the aircraft is its lack of humidity. Literally comparable to the dryness of the air in a desert, the lack of moisture in the air can wreak its own effects. The biggest concern for the air traveler that results from a lack of humidity is trying to remain hydrated. A few of the effective ways to stay hydrated is by drinking lots of water, and by applying lots of moisturizer to the skin.

At 39,000 feet, the cabin air conditions are certainly different than the air conditions you'll normally experience on the ground. To arrive healthy at your destination it may be important to consider the air you'll be exposed to in the air.
