Sweating responses to central and peripheral heating in spinal man.

Studies of central and peripheral heating of a resting spinal man (T6) were performed under various ambient temperatures (20-34 degrees C). It was found that at a constant core temperature, sweating could not be initiated by sentient skin heating alone, but skin cooling alone did produce a rapid decrease in sweating response. Central heating alone induced sweating responses and the central temperature thresholds of sweating were inversely related to the ambient (sentient skin) temperatures. The local and mean sweating rates were found to be linearly related to the core temperature. The slopes of local sweating rates versus the core temperature vary increasingly with the following locations: chest, forearm, and forehead; but the slopes of mean sweating rates versus core temperature were essentially constant.

Sweating responses of normal, paraplegic and anhidrotic subjects.

Dynamic sudomotor response to changing ambient temperatures (30 C to 45 C) was measured on eight unacclimatized subjects including five normals, two paraplegics and one anhidrotic patient. Mean sweating rates, computed from five simultaneously observed local rates, were used to compare the overall sudomotor response to heat exposure of the three groups. In the normal subjects, an average rise of 0.34 C in oral temperature and 2.5 C in mean skin temperature was found in a period of 65 minutes. The paraplegics developed a higher rise in both oral and skin temperatures due to a lower sweating rate in the insentinent region. (Insentient describes the sensory state of the skin below the level of the lesion where the subject has no awareness of surface stimulation). A relatively higher sweating rate was observed on the forehead and the cyclic sweating behavior of the insentient skin was not synchronous with that in the sentient. (Sentient describes the state where partial or total awareness is elicited by stimulation). The anhidrotic patient showed a twofold increase of moisture loss from the skin but no cyclic pattern of sweat gland activity on exposure to heat. In this case, hyperthermia developed with a rise in oral temperature of 1.1 C in 52 minutes versus 0.4 C rise in the controls in a period of 63 minutes.
