Jakarta, When in cold rooms and air-conditioning is usually someone frequent colds. Then is it true the news that AC can make a person more susceptible to colds?
Some people believe that the decrease in temperature that occur suddenly may affect a person's immune system, making people more susceptible to illnesses such as colds.
"Colds and other respiratory diseases are always associated with cold air. But cold air is not the cause, but a virus," said Dr. Ujwala Kaza, an allergist immunologist from New York University Langone Medical Center, as quoted by the NYTimes, on Thursday (28 / 7 / 2011).
Even so researchers from Cardiff University in Wales say there may be a contribution from the AC against respiratory tract infections. This is because the AC extract moisture from the air that could dry out the protective mucus that lines the nose, thus providing an opportunity for a virus or bacteria to multiply in the nose.
Besides the AC that are not cleaned regularly can also be a cause, because the AC will be a gathering place for microorganisms such as bacteria, viruses or fungi that can later be released into the air.
Studies conducted in 2004 of 920 adult women found that people who work in offices with central air conditioning have a higher level not to miss work due to illness and visits to the doctor ENT (ear nose throat) are more frequent.
While the 1998 study conducted on 800 office workers also found more symptoms of the disease appeared in workers who have air-conditioned office than workers in naturally ventilated office.
While cold symptoms that appear as watery eyes and runny nose is one of the body's response to cold air. This response is useful to help prevent dryness of the mouth and nasal lining.
To prevent diseases caused by cold air, try to clean the air conditioner on a regular basis, still consume enough water even though no body does not feel thirsty to prevent dehydration and dryness as well as the occasional out of the cold room for a while.
