Rankin, Mary L., Latham, Georgia, Peters, Robert D. and Penetar, David M. (1989): The Effects of 48 Hours Total Sleep Deprivation on Human Physiology, Mood, and Memory. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 625-629.

“Previous research regarding the effects of sleep deprivation (SD) on human physiology and mood has yielded conflicting results. These findings may in part be due to the use of small sample sizes and the failure to separate out the pure effects of SD from those of circadian rhythms during data analysis. One purpose of this study was to clearly identify the effects of 48 hours of SD on blood pressure, temperature, heart rate, and mood by overcoming the limitations of previous research. A second purpose was to evaluate the effects of SD on recognition memory. A repeated measures design was employed to collect physiological, mood, and memory data over a 48 hour period. While strong circadian rhythms were observed for most of the physiological and mood variables, recognition memory was unaffected by 48 hours of SD.”
