If the relative humidity is lower than 50%, irrespective
of the temperature, the symbol
humidity appears.
If the relative humidity is too low, this often leads to
headaches and drying of the mucous membranes, es-
pecially of the nose and the eyes. In turn, this irritation
increases susceptibility to germs and is thus often the
precursor to infections.
An excessively high relative humidity has adverse effects
in particular on people with poor circulation. In addition,
there is a risk of mould in closed and insufficiently aired
rooms, which is at the same time a further health risk.
Therefore, always make sure that rooms are aired well/
regularly and that there is a „healthy" relationship bet-
ween temperature and relative humidity.
