Abstract

A method for evaluating the effectiveness of a person to perform a task based on his/her previous or predicted sleep activity is provided. The method can be used to predict changes in task effectiveness at any time of day, based upon numerous patterns of sleep and activity, either experienced or planned for the future. The method takes into account progressive increases in sleep deprivation, the effects of the time of day on performance, and changes in the time when a person sleeps and works. The method also accounts for the quality of a sleep interval and a person'"'"'s sleep inertia, the temporary slowing of performance immediately after awakening. The method is homeostatic. Gradual decreases in sleep debt decrease sleep intensity. Progressive increases in sleep debt produced by extended periods of less than optimal levels of sleep lead to increased sleep intensity. As a result the method can predict the normal decline in sleep intensity during the sleep period and the normal equilibrium of performance under less than optimal schedules of sleep.
