Is your air making you sick

The term air conditioning refers to the cooling and dehumidification of indoor air for thermal comfort in buildings and motor vehicles. We usually call them A/C or aircon that keep us comfortable in our indoor environments. Aside from added comfort, air conditioners may cause several health hazards. In fact, the problems associated with air conditioners arise out of overuse.

Air conditioning exaggerates the effects of arthritis and neuritis. It also causes problem for those with sinus trouble, causing their heads to become blocked. In addition to these obvious reactions to an air conditioned environment there are many far more delicate reactions that can adversely affect a person's health.

Studies between those who have worked for prolonged periods in air conditioned offices and those who work outdoors have shown that the people exposed to air conditioning are more prone to colds, flu and other minor ailments. It has also been seen that the body undergoes a certain amount of stress when it is forced to go from a very hot environment into an air conditioned one; eventually this can cause problems.

It is also clear that those who spend too much time in an air conditioned situation are not able to readily cope with hot temperatures. Indeed many people have been made unwell by extreme variances between outside and inside temperatures.

Air conditioners in cars also have some problems. According to a researcher (American Automobile Safety Organisation), extended exposure to car air conditioner may cause drowsiness and not being able to concentrate on driving.

Micro-organisms have been found within the units that may cause breathing problems. Researchers at Louisiana State Medical Center identified eight different types of mold living inside of 22 of 25 cars tested.

Air conditioning units can also circulate air-borne diseases, such as Legionairre's Disease. Without proper filtration or maintenance a typical system will simply recirculate pollutants.

However, spending just a few hours a day in an air-conditioned room is not harmful for one's health. But, if air conditioners are not well maintained, they can cause some very serious problems. A dirty air filter can harbor pollen, fungi and bacteria and allow millions of microorganisms into the room, possibly triggering an asthma attack, irritation of the eyes, nose, and throat — even flu like illness.Some simple maintenance steps will help alleviate these problems. It is better to vacuum the air filter every two to four weeks and then wash it in soapy water. Be sure to let the filter dry completely before reinstalling it.
