Predicting nighttime alertness following prophylactic naps or, "How long should I nap before that all-nighter?"
Sleep Res 1991 Jan; 20:417
Laboratory studies have demonstrated that napping before an extended vigil (I.e., prophylactic napping) can delay the decline in alertness durlng the vigil. An Important practical question from this research concerns the minimum amount of sleep required to maintain a given level of alertness. Setting nap lengths at a minimum is Important because biological rhythm, environmental, social, and other practical factors mitigate against sleeping during the day. Here we describe a multivariate equation for establishing the minimum nap length necessary for maintaining a desired level of alertness (as measured by the Multiple Sleep Latency Test (MSLT)) for extended operations up to 47 hours.
