THE winter typically known as dry weather and the low temperatures increases respiratory diseases and allergies.
In front of the station, the alerts regarding relative humidity air humidity (RH), especially indoors, are also gaining strength. According to data from World Health Organization (WHO), for air quality to be considered good, the level must be between 40% and 70%.
THE CNN Michele Andreata, a home health pulmonologist, explains that air humidity refers to the amount of water vapor present in the atmosphere .
“It is measured in terms of relative humidity, which expresses the percentage of current water vapor in relation to the maximum that the air can contain at a given temperature,” he says.
According to the professional, balanced air, in addition to bringing respiratory comfort also prevents the proliferation of harmful microorganisms. “Humidity levels below 30% can cause dry airways, worsening respiratory conditions such as eye irritation, dry skin and increased susceptibility to infections.”
However, just like low percentages, excess levels are also harmful to health. “High levels encourage the growth of fungi and mites, triggering allergies and respiratory problems,” warns the pulmonologist.
How do you know if the humidity level is correct?
Michele points out that in addition to measuring using hygrometers, some signs also indicate balance. “Signs of good humidification include the absence of respiratory discomfort, irritation of mucous membranes and skin, and the absence of excessive condensation or mold on the walls,” she says.
