Title: Thermal sensation, skin blood flow and frequency analysis of cutaneous vasomotor rhythms
Abstract: 1.|In a climatic chamber, the air temperature of which (ambient or room temperature) was increased from 12 to 45°C, 11 human subjects estimated their local thermal sensations of forehead, both hands and foot. Corresponding local skin blood flows were measured. 2.|The subjects perceived local temperature sensation (LTS) and local thermal comfort (LTC). LTS was a linear function of local skin temperature (Tlocal) and only slightly dependent on mean skin temperature (Tsk). LTC was inverted U-shaped fucntion of Tlocal and also dependent on Tsk. 3.|The skin blood flow at forehead, both hands and foot as a function of increasing room temperature (TR) showed that vasomotor oscillations began at different Tlocal and Tsk values, while rectal temperature was almost constant. There was no correlation between skin blood flow and LTS or LTC. 4.|Frequency analysis of skin blood flow, measured at four skin locations, always showed long time rhythms with periods of some minutes. With the increase of (Tlocal) further blood flow rhythms of higher frequencies with periods of 10–20 s occured. The amplitudes of the occuring frequencies rose to their maximum with the increase of TRS between 39 and 41°C.
