Humidifier for a better climate and for the benefit of health
Especially during the heating season, the relative humidity often falls below the
recommended range for living and working spaces. This has an unfavourable effect on the
well-being and health of people and animals and can also promote diseases of the
respiratory system if the indoor air is permanently very dry. A too dry climate can also be
harmful for inventory and plants. This effect can be counteracted with our humidifier.
In the field of human medicine, a balanced humidity of the ambient air is recommended.
However, especially in closed, poorly ventilated and well-heated rooms, such values are
often fallen short of, which can lead to reduced respiratory performance and impairment of
the skin or mucous membranes. This is especially the case in winter, as the cold outside
air then has only a low absolute humidity. Therefore, it should be re-humidified by a
humidifier after it has been warmed up to room temperature in order to prevent the relative
humidity from dropping too much.
In very cold regions or at cold times of the year or at night, the human organism often
shows an increased fluid consumption, although the opposite should rather be assumed
due to the lack of fluid loss through sweating. This is due to the humidification of the dry
inhaled air and the associated loss of water. If the cold outside air is heated during
inhalation, its water vapour capacity increases and thus also lowers the relative humidity.
In contrast, the saturation deficit increases and the tendency of the liquid lung tissue water
to change into the gaseous aggregate state increases. In summer or when the ambient air
is warm, the inhaled air is hardly warmed up any further and therefore retains its usually
high relative humidity. If the additional water losses through sweating are not too great
here, the body's water requirement is therefore higher in cold ambient conditions.
Increased humidity is beneficial for breathing, as oxygen then reaches the bloodstream
more easily via the alveoli. The skin needs a high level of humidity in order not to dry out,
as this is closely linked to skin moisture. Mucous membranes are particularly susceptible to
drying out, as they have little protection against evaporation and depend on their high
humidity to maintain their functions. Thus, low humidity of the nasal mucosa can result in
an increased incidence of nosebleeds. In general, the skin's immune defence is weakened
(increased risk of catching a cold) and its ability to exchange substances is reduced, which
particularly affects the oral mucosa. Low humidity also increases the susceptibility to skin
irritations or redness or even skin inflammations.
