W tej wilgotności świetnie rozwijają się roztocza. Dobrze jest
utrzymywać <=50%.

Recommendations for comfort

Humans control their body temperature mainly by sweating and shivering.
The United States Environmental Protection Agency cites the ASHRAE
Standard 55-1992 Thermal Environmental Conditions for Human Occupancy,
which recommends keeping relative humidity between 30% and 60%, with
below 50% preferred to control dust mites. At high humidity sweating is
less effective so we feel hotter; thus the desire to remove humidity
from air with air conditioning in the summer. In the winter, heating
cold outdoor air can decrease indoor relative humidity levels to below
30%, leading to discomfort such as dry skin and excessive thirst.
