How pleasant,To flee from the scorching heat to a well-tempered department store or to turn on a cooling fan in the car while other people’s shirts are sticking to their backs wet with sweat – air conditioning systems can make life easier, and not just in summer. But they are not entirely unproblematic. As pleasant as the cool air is on a hot summer’s day, the symptoms caused by the air in an air conditioning system can be just as uncomfortable.
Health disadvantage of air conditioning systems
Many people who are regularly exposed to air-conditioned air in the office, for example, complain of impairments: too strong drafts, too much cold, too dry mucous membranes. As a result, there are more illnesses, primarily colds , problems with the bronchi and sinuses and increased susceptibility to infections. Irritated skin and mucous membranes, headaches and poor concentration are also attributed to the conditioned air.
And reports are circulating again and again that air conditioning systems can mutate into killers if they are not properly maintained: Legionnaires’ disease in particular, caused by Legionella , can lead to severe, potentially fatal pneumonia .
The air conditioning smells? Cleaning helps.
Microorganisms such as bacteria and fungi lead an unnoticed and undisturbed life of their own in the filters and pipes of the air conditioning systems. They collect and multiply and are thrown directly into the human organism with the air flow. When the humidity is high, the molds are especially happy. High levels of moisture are created by condensation water when hot air cools down. Air conditioning systems must be professionally serviced at least once a year – technical and hygienic deficiencies can only be remedied in good time through such air conditioning maintenance.
Air conditioning makes you sick
Even if the air conditioning system is optimally maintained, it can have disadvantages: With outside temperatures of 30 or 40 degrees Celsius and high humidity, everyone works up a sweat . In an air-conditioned and therefore cool office, restaurant or hotel room, it is easy to catch a cold – the abrupt change between high and low temperatures stresses the immune system and weakens the immune cells. The sweat suddenly cools down, the dry air also irritates the mucous membranes of the upper airways – many types of viruses have an easy job and the stiff neck is not long in coming. In addition, the cardiovascular system is also heavily stressed.
In order to avoid sudden temperature fluctuations, especially in hot summer, air conditioning systems should not be set too cool – the temperature difference between indoors and outdoors should not be more than 6 ° C. If necessary, keep a jacket handy, even in summer. American researchers have discovered that air conditioning makes you fat. What sounds like an April Fool’s joke is justified as follows: In indoor rooms that are always the same and well-tempered, you sweat and shiver less often – and thus use less energy.
Air conditioning also blocked the natural summer diet mechanism, which the heat uses to reduce our appetite, especially in summer.
Regularly maintain air conditioners in cars
Air conditioning is becoming more and more standard in cars: when a car quickly heats up to 50 degrees and more in the sun, you are not only grateful for cooling yourself down, but also for being able to transport your fresh food home safely. But be careful if you get a musty smell. What applies to office spaces should also be observed in the microcosm of the car: The cabin air filter, through which the air from the air conditioning system is blown, should be changed about once a year so that pathogens and pollen cannot spread through the car.
The main problem here is the evaporator in the dashboard. This is where the condensed water, which is created automatically during cooling, is collected and evaporated. The microorganisms feel particularly comfortable in the damp environment. Evaporators need to be cleaned and, ideally, disinfected. In a car, a temperature of 23 to 27 degrees and a humidity of 35 to 65 percent are ideal for driving.
