\"\"In the last few weeks, winter has once again made us feel what \u2018really cold\u2019 means. Many people at home have turned the heating knobs all the way to the left – and are now suffering from the consequences of dry heating air. It dries out our mucous membranes, reduces their cleansing function and creates an ideal habitat for viruses. It also causes undesirable effects such dry nose and irritated eyes, as well as coughs, colds and sore throats. Because low humidity also increases the lifetime of infectious corona aerosols in the room air, there is virtually every reason to humidify the air as much as possible in the future.<\/h2>\n

<\/p>\n

Doctors and biologists tell us time and again how crucially the immune defence of the mucous membranes depends on the humidity of the room air. This is because as air humidity decreases, the removal of microorganisms and viruses in the mucous membranes decreases given the drying out of the cilia, meaning they can no longer perform their cleansing function. Experts therefore recommend a relative humidity of between 50 and 60 percent as a comfort zone for living rooms and offices. You should measure the humidity in the room at the first sign of excessively dry indoor air. The measuring instrument used for this is a so-called room thermohygrometer, such as the one Trotec offers with the precise and inexpensive BZ05. At the latest when the thermohygrometer permanently indicates an air humidity value below 40 percent, you should act to achieve normal air humidity in the room again.<\/p>\n

Air Humidity of 50% reduces the risk of corona infection<\/h3>\n

Did you know that adequate room humidity helps prevent corona aerosol infection? Scientific studies show that when the relative humidity of indoor air is below 40 percent, corona aerosols emitted by infected individuals absorb less water. This means that these particles remain lighter and can continue to fly through the room air. But the wider the radius of the emitted infectious aerosols, the greater the risk of infection for healthy people in the room. Conversely: if the air humidity is right, the aerosols quickly absorb moisture, become heavier and therefore fall to the ground more quickly.<\/p>\n

What is the best way to humidify dry air?<\/h3>\n

From house plants to small water bowls or even automatic air humidifiers, which, depending on the model, evaporate, mist or vaporise, there are numerous options for restoring the optimal room humidity level of 50 to 60 percent. But you should also make sure not to spread harmful germs in your living or working spaces with the humid air.<\/p>\n
