Circadian change of sweating rate measured locally by the resistance hygrometry method in man

Summary There existed circadian change in the sweating rate locally measured from the anterior of the left thigh: the sweating rate showed a remarkable decline during the period 2.00–5.00 h, while at other times throughout the day it generally remained high. This reduction seemed to be independent of sleep or sleeplessness.Acknowledgment. The authors thank sincerely the late Prof. S. Mizunashi for her constant encouragement throughout the work.
