Abstract: Skin pressure application on one side of the lateral chest of experimental subject led to a decrease of sweat production on the ipsilateral side of the skin. This is the so-called hemihidrotic phenomenon which was first described by Kuno. The purpose of the study was to reconfirm the hemihidrotic phenomenon by the application of skin pressure with a special newly designed apparatus. Local heat load or general heat load was applied to induce thermal sweating, detected by capacitance hygrometer-sweat capture capsule method on both sides of the forehead and chest in an environmental control chamber. Sweat-onset time was markedly prolonged on the ipsilateral side of skin pressure application. In addition, strong suppression of sweat production was observed close to the skin pressure application area. Skin temperatures were detected by means of thermistors and thermography, under the condition of no sweating. Chest skin temperature detected by thermistors at the ipsilateral side of pressure application was lower than that of the contralateral side. However, cheek skin temperature detected by thermography at the ipsilateral side of pressure application was higher than that of the contralateral side. Frequency reduction of synchronized sweating expulsions between the right and left chest as well as on the right and left forehead was induced either on the right or left side of skin pressure. This might indicate that the effect of skin pressure influences the spinal and the supraspinal function.
