Caffeine is the most widely consumed stimulant to counter the effects of sleep loss on neurobehavioral performance. However, to be safe and most effective, it must be consumed at the right time and in the right amount. This study proposed an automated optimization algorithm to identify safe and effective caffeine-dosing strategies that maximize alertness under any sleep-loss condition.

"We found that by using our algorithm, which determines when and how much caffeine a subject should consume, we can improve alertness by up to 64 percent, while consuming the same total amount of caffeine," said principal investigator and senior author Jaques Reifman, PhD. "Alternatively, a subject can reduce caffeine consumption by up to 65 percent and still achieve equivalent improvements in alertness."

[...] The algorithm was assessed by computing and comparing dosing strategies for four previously published experimental studies of sleep loss. For each study, two dosing strategies were computed -- one which enhanced the predicted PVT performance using the same total amount of caffeine as in the original studies, and another which achieved an equivalent level of performance as in the original studies using a lower amount of caffeine.

    And a little about the tool that is referenced:
    https://2b-alert-web.bhsai.org/ [bhsai.org]

    This software tool predicts alertness of an "average" individual as a function of sleep/wake schedule and caffeine consumption. Specifically, this tool allows users to manually enter a sleep/wake schedule and caffeine dosing and timing, and displays the corresponding predictions for three different psychomotor vigilance task alertness statistics.

    This tool can be used to:

    1. Assess the effect of different sleep/wake schedules and caffeine consumption
    2. Design sleep/wake and caffeine schedules to optimize alertness
    3. Generate hypotheses that can be experimentally tested
    4. Coming soon: the ability to optimize caffeine use
