Abstract
The aim of the study was to test the effect of skin creams and their components in windy (3 m/s) and cold (-15 degree(s)C) conditions on face temperature and heat flux. The tests were carried out in a climatic chamber with 18 persons sitting in front of the opening of the wind tunnel, the wind directed against the face. Skin temperatures were measured from 4 points on both sides of the face with thermistors and the heat fluxes were measured using heat flux sensors on both cheeks. Also the ambient temperature and wind were registered. In addition to these measurements an IR thermal scanner was also used to measure the spatial and temporal distribution of temperature variation on the face during the exposure. The results were continuously recorded on VHS-video tape. Using still pictures from recorded material the area temperature of the cheek was measured, which described the mean temperature of the cheek. Test periods were 30 minutes and the same test subjects were not used until 48 h after the previous cold exposure. The test persons were young (20 - 30 years) healthy male persons. The total number of tests was 38.
