Effects of carbon dioxide inhalation on sweating

Abstract

Inhalation of 6% carbon dioxide by male subjects exposed to three different ambient temperatures resulted in increased sweating as measured by resistance hygrometry. The increase, which occurred in all body areas studied, reached approximately 100% over the control levels. All measured body temperatures decreased during or immediately following the carbon dioxide period. In the recovery period a marked depression of sweating occurred which ended as skin temperatures increased. body temperature; thermal effector activity (cyclic sweat gland activity); skin temperature; tympanic membrane and hypothalamus temperatures; resistance hygrometry responses to heat Submitted on April 24, 1963
