Eight nude resting male subjects were immersed in water. The temperature of the bath was varied cyclically from -5 to 42 deg C. Similar experiments were performed in air with temperatures varying from -5 to 120 deg C. Skin temperatures oscillated sinusoidally with amplitudes varying from 1 to 10 deg C and periods varying from 3.75 to 30 minutes. Variations in skin temperature below 30 deg C did not affect the oesophageal temperature. Sinusoidal variations in skin temperature above 34 deg C were reflected in nearly sinusoidal alterations in the oesophageal temperature. Sinusoidal variations in oesophageal temperature were accompanied by nearly sinusoidal alterations in rectal, sublingual and tympanic membrane temperatures, with damping characteristics and phase shifts typical for each site of measurement.
