Perception of temperature elevation in human seasonal heat adaptation.

Higher values of the exponent power function of the perception of temperature elevation (1.66, 1.32, and 1.50) in the summer than in the winter (1.40, 1.08, and 0.84) were established in seasonal investigations in people at room air temperatures of 20, 28, and 40 degrees C. Consequently, following adaptation to the seasonal high temperature a person can feel a smaller temperature increment than in the winter. This suggests a reorganization in the functional activity of the temperature analyzer under the prolonged influence of seasonal high temperature.
