Peut-on tumbler malade à cause de climatisation?

« Est-ce qu’on peut tomber malade à cause de la clim? », nous demande Victoire, de Blois. With les vagues of heat that touchent in France, la climatisation tourne often in plein mode in offices or shops. Mais celle-ci peut-elle nous faire tomber malade? Comment éviter les risques linked à la air conditioning? Ouest-France answers you.

On ne peut pas attraper un rumme à cause de la clim

The expression “attraper froid” is trompeuse. Colds are the result of an infection and therefore contact with a virus. Il n’est pas lié à la temperature. Si le virus est présent autour de nous, on risque de tomber malade, que l’espace soit climatisé ou non. The virus transmits through gouttelettes projected to the infected person, when they contact the principal or through contaminated objects. More than 200 viruses can cause a cold.

Il est vrai, however, that le froid affaiblit our immune system. It can make him more vulnerable and therefore increase the risks of being contaminated by the virus.

It is very likely that air conditioning contributes to the propagation of microbes. “What is a risk factor for viral infections”indicates Dr. Matthieu Calafiore, doctor généraliste et maître de conférences à l’université de Lille, questioned by par Information about France . “Ces equipment that includes filters that allow to minimize the risks and the air is renewed regularly. »

Climate can be at the origin of irritations

Climatisation peut causer parfois ce qui ressemble à un rhume, sans en être un. “L’un des principes de air conditioning is de refridir l’air et de l’assecher, explains Dr. Calafiore. This dries up the nasal mucous membranes that are fragile and, in reaction, they become humidified a little more, which can lead to rhinitis (nasal discharge). Mais celle-ci n’est pas liée à une infection ».

Si l’assechement touche les sinuses, cela peut causer des douleurs similaires à celles d’une sinusitis. Again, this can also make us more vulnerable to germs and viruses.

Air conditioning can also cause ocular dryness. “La surface de l’œil est comme la muqueuse nasal: a surface of liquid allows the escape of pus and microparticles”pursued le docteur. “Sans ce filters, the eye is more sensitive and there is an increased risk of allergic conjunctivitis”.

Pour the problems, air conditioners are most often equipped with an air humidification system.

Comment éviter les risques linked à la air conditioning?

Plusieurs bonnes pratiques are recommended to avoid air conditioning risks. First of all, the temperature difference between the interior and the exterior must not be too large. Le mieux est de conserver un écart de cinq à sept degrés maximum. “L’homme supporte assez difficilement des changes of temperature trop brutaux, c’est-à-dire de plus de 7 °C”says Dr. Calafiore.

Air conditioning needs to be maintained regularly, in buildings like vehicles. “It is particularly important to regularly replace the particulate and infectious agents retention filters and to check the absence of stagnant water in the cooling system”rappelle le doctor.

Numerous bacteria can grow in the stagnant water of legions, responsible for legionnaires’ disease. It is a pulmonary disease causing respiratory distress. When the air conditioning is properly maintained, the risk of contracting this disease is still very low.
