We studied the effect of different levels of hypoxia (10, 12 or 13, 15, and 18% O2) on the sleep-waking pattern (SWP) and the maximum-minimum core temperature of warm-acclimated (WA) and cold-acclimated (CA) rats at their neutral temperature, 29 degrees C. Whereas the SWP of WA rats showed a trend toward increasing disruption as the degree of hypoxia increased, CA rats exhibited no such trend. The effect was chiefly on the frequency of state changes and less on epoch durations. The SWP of WA rats was more vulnerable to hypoxia than that of CA rats. Maximum and minimum body temperatures of WA and CA rats were not significantly affected by O2 lack down to 10% inspired O2. We conclude that in the rat 1) hypoxia primarily affects the neural mechanism that governs the frequency of changes in sleep-waking states; 2) the extent of alterations in SWP's depends on the ambient temperature to which the rats are acclimated; and 3) hypoxia does not significantly affect deep body temperature at the animal's neutral temperature.

Six male human subjects were placed in a situation of physiological conflict, fatigue vs. cold discomfort. Dressed in swim suits and shoes they walked at 3 km X h-1 on a treadmill placed in a climatic chamber. The slope of the treadmill was varied from 0 to 24% and the ambient temperature (Ta) from 25 to 5 degrees C. The subjects could choose Ta when slope was imposed or the converse. They rated pleasure and displeasure of Ta and exercise. Deep body temperature and heart rate were monitored. The results show that the subjects adjusted their behavior to maintain approximatively steady deep body temperature and to limit heart rate below 120 beats X min-1. The physiological compromise was thus correlated to the drive for maximal pleasure-minimal displeasure in the two sensory dimensions fatigue and discomfort.
