Clinical and statistical results obtained from the examination of a group of 65 healthy men, whose skin temperatures were measured at rest and during reflex thermal vasodilatation, are evaluated. Skin temperature was measured by infrared thermography under standard conditions on 5 locations. The assessment included changes in skin temperature in relation to the measured site, resting temperature, probands' age and estimation of lateral symmetry. The conclusions are documented by graphs giving the pattern of temperature changes for the whole group and subgroups of acropoikilothermal and acrohomoiothermal individuals.
