Abstract
Measurements of expiration temperatures were carried out under different climatic conditions. In one series of experiments the ambient air temperature was varied, in another the relative humidity of the ambient air. The temperatures of the ambient air ranged between −5°C and 30°C and the relative humidity between 10% and 90%. The results reveal a high variability of the expiration temperatures, when the ambient air temperature is changed, and almost constant expiration temperatures, when the relative humidity is altered but the ambient air temperature is kept constant. Nasal expiration temperatures are more sensitive to changes of the meteorological parameters than oral expiration temperatures.
