However, the first problem, the air conditioning not only cools the air, it dries it. This can cause, in the most fragile subjects but also in others if used excessively, irritation of the nasal passages, as well as dehydration. This is confirmed by Dr. Matthieu Calafione, interviewed by Franceinfo: “The principle of air conditioning is to recycle and cool the air while it dries it. Hence the appearance of eye or nasal irritation, itching, desire to sneeze, epistaxis (epistaxis) or crusting. Eye irritation particularly affects people who wear contact lenses. To mitigate this drying risk, some devices are equipped with an air humidifier.
Second point, would air conditioning favor the spread of viruses? Consumer information and defense magazine Que Choisir points out as obvious that closed-circuit air conditioning, which only agitates the air (just like fans), offers better circulation than a virus. So there is a risk when a virus is present in space. The site specifies that “there are no precautions to be taken if everyone is well”.
Also, according to Dr. Wassim Labaki, a professor of internal medicine at the University of Michigan, quoted by the Huffington Post, “air conditioners are likely to contain infectious or allergenic organisms, such as dust mites, so it is essential to maintain them. and replace the filter regularly to avoid the circulation of stale air. “
Finally, the third point, the risk of rheumatism or joint pain. During long journeys by car or to the office, do not direct the flow of cold air towards you, this would expose you to “stiff neck and other neuralgia”, indicates Le Midi Libre. The effect of cold makes the muscles stiffer and can lead to contractures. Working at the computer with cold air on your neck is the winning duo that will take you directly to the physiotherapist!
