Abstract
Summary
Observations were made on 11 subjects of varying ages to discover the environmental conditions necessary to initiate sweating in man. These studies, performed in a room designed for close control of temperature and humidity, indicate that an environmental temperature of 34.4° C and relative humidity of about 50% are essentially the threshold level for sweating in normal man resting in bed. Exercise and increased rate of heat production are associated with a proportionate lowering of the threshold.
