Temperature perceived is determined by the combination of actual temperature and relative humidity.
The ratio of air humidity and temperature is proportional: the higher the temperature, the more air is capable of retaining steam.
De’ Longhi has identified ideal comfort standards: the graph below highlights the standards that achieve such conditions.
