Peripheral body temperature and thermogenic drinking in cold-treated rats.
Transfer of rats abruptly from air at 5 degrees C to air at 26 degrees C was accompanied by a significant increase in water intake (thermogenic drinking) during the first hour after transfer. A possibility existed that the increased water intake observed under these conditions was attributable to the rapid change in skin temperature. Thus, the objective of this study was  to determine the effect on thermogenic drinking of a slow, as opposed to an abrupt, change in ambient temperature. The results indicated that warming room air rates of either 0.5 or 1.0 centigrade deg/min had no effect on thermogenic drinking when compared with the water intake of rats removed abruptly from cold. Thermogenic drinking does not appear to be initiated by a specific pattern of changes in peripheral temperature relative to colonic temperature.
