Hemihidrosis Due to Skin Pressure with Particular Remarks on the Intensity and Area of the Pressure Stimuli

Abstract

Sweating of symmetrical areas of the torso was measured by means of both the filter paper method and electrohygrometric method. Spontaneous sweating rates of the left and right side of the upper and lower chest and the back were statistically highly correlated. Reduction of sweating by pressure application to the unilateral subaxillary region (‘pressure hemihidrosis’) was studied quantitatively with 12 combinations of pressure stimuli, i.e., 1, 2, 3 and 4kg weights applied to disks with a surface area of 2, 6 and 16.6cm2, respectively. The amount of reduction in sweating rate was proportional to both the intensity and the surface area of pressure applied. It was revealed that hemihidrotic effects induced from the unit area of pressure stimulation was statistically highly correlated to the pressure intensity.© 1981, PHYSIOLOGICAL SOCIETY OF JAPAN.
