We measured rectal, lateral chest wall, and axillary temperature every half hour for at least 24 h while subjects were living normal life-styles and keeping a sleep/activity diary. We then used a purification method to estimate the decrease of temperature due to sleep and the increases due to sitting, standing, walking, or exercising, as well as the parameters of the cosine curve that described the "purified data." Cosinor analysis of raw and purified data showed that the acrophases from both skin sites were much more variable and up to 8 h later than were those from the rectum (particularly if exercise had been taken), even though the acrophases from the two skin sites were similar to each other. For rectal temperature, there was an increase in the size of the masking effect as activity progressed through the sequence: sitting, standing or walking, exercising. In contrast, for both chest wall and axillary temperatures, although sitting produced masking effects similar to those for rectal temperature, masking effects due to standing or walking and exercising were much smaller, and sometimes they were even less than the masking effects due to sitting. These results indicate that our measurements of cutaneous temperature did not act as a substitute for rectal temperature, particularly when the subject was physically active rather than sedentary.
