Answer to Question 1:

Hi Susan,

Air conditioning is the control of the temperature, humidity and air movement and cleaning of air in confined space. Who would be without air conditioning?
In hot, humid climates it is more than a modern comfort – it is an essential element in getting through those sweltering, sticky days. But, like most modern conveniences, air conditioning has its down-sides. Are they sufficient to make you think twice about having air conditioning at your place? Many researchers believe they are.

The problems associated with air conditioners arise out of overuse. With the ease of fingertip control many people assume that the more they use their unit the better. This, however, is not the case. Air conditioning aggravates the effects of arthritis and neuritis. It also causes trouble for those with sinus problems, causing their heads to become blocked. In addition to these obvious reactions to an air conditioned environment there are many far more subtle reactions that can adversely affect a person. Studies between those who have worked for prolonged periods in air conditioned offices and those who work outdoors have consistently shown that the people exposed to air conditioning are more susceptible to colds, flu and other minor ailments.

Of course there are also positives to air conditioning. It creates a pleasant atmosphere inside, regardless of the external temperature. It may eliminate heat rash and help hay fever sufferers by removing pollens from the air. The removal of dirty and dry air is also accomplished by air conditioning. We should not become reliant on it and should always use it sparingly in that way we get the benefits while avoiding the detriments of air conditioning.

Basically legislation states that; sufficient fresh air be provided for in all enclosed spaces, that staff are not exposed to draughts from air conditioning and that the temperature is appropriate (sedentary office work is 17.5°C for the first hour at work and maintained at 16°C as far as reasonably practicable after this). Hopefully this give you some idea in regards the use of air conditioning.

Paul
