Partial sleep deprivation (sleep for three to four hours followed by forced wakefulness for 20-21 hours) was equally as effective as total sleep deprivation (being deprived of sleep for 36 hours), and medication did not appear to significantly influence these results, according to the first meta-analysis on the subject in nearly 30 years, from researchers at the Perelman School of Medicine at the University of Pennsylvania.

However, we returned to those monsters, with fresh wakefulness on my part, and we left their eggs in the sand for the sun to hatch; and we ran away from them, and baffled them by constantly turning, which they were unable to do quickly, on account of their unwieldy make; and we went into the water after them, as natives, and put sharp pieces of timber down their throats; and in short we ran the whole crocodile gauntlet.
(David Copperfield, by Charles Dickens)
They extracted pertinent information from publications meeting predefined inclusion and exclusion criteria to explore the effects of water-based passive body heating on a number of sleep-related conditions: sleep onset latency—the length of time it takes to accomplish the transition from full wakefulness to sleep; total sleep time; sleep efficiency—the amount of time spent asleep relative to the total amount of time spent in bed intended for sleep; and subjective sleep quality.
