...hours, the liver reverses the starch-storing process and turns the glycogen into energy. When the baby begins feeding, the liver goes on to a normal, lifelong rate of glycogen manufacture. ¶ "Such stuff as dreams are made on" brought unsuspected data from Chicago Physiologists William Dement and Nathaniel Kleitman: a person can dream for an average of two hours a night and remember little of it; his chances of remembering decrease the longer he sleeps after the dream ends; dreaming does not take place while the body is restless in light sleep; far from flashing by almost instantaneously...
After every afternoon movie she saw, for two years, a teen-age acquaintance of Chicago Physiologist Nathaniel Kleitman took her own temperature. A girl in her 20s took similar readings after 29 shows in two months...
...Science Dr. Kleitman reports that a movie raised the teen-ager's temperature one degree above her usual temperature at the same hour (once she topped 100°). The older girl usually heated up half a degree; when she saw a double feature, the rise was less. (Possible explanation: temperature ordinarily falls as evening advances...
...Kleitman, an expert on human body temperature who once lived in a cave to prove that habits can change body heat's diurnal rhythm (TIME, July 18, 1938), concludes: "On the basis of occasional data ... on many subjects . . . and through an analysis of multiple readings on two ... it appears that attending motion picture shows . . . is by no means relaxation in the physiological sense. . . . It remains to be seen whether the collective change in the body temperature of a preview audience can be used to predict the box-office success of a film...
After 32 calendar days underground, the two scientists emerged last week. Results: Richardson adapted himself well to the long day, sleeping soundly at the prescribed periods and stretching his temperature cycle to one of 28 hours. Kleitman had much difficulty, his periods of wakefulness and sleepiness and his temperature cycle clinging to the 24-hour schedule. This indicated that ability to break away from the 24-hour rhythm, while not impossible, varies with different individuals. Perhaps age is a factor, since Kleitman is 43 and Richardson only...
