Summary:

According to a recent study, a newly developed algorithm may be the key to optimizing alertness with caffeine.

 

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."

 

Reifman is a senior research scientist and director of DoD Biotechnology High Performance Computing Software Applications Institute and the Telemedicine and Advanced Technology Research Center at the U.S. Army Medical Research and Materiel Command in Ft. Detrick, Maryland.

The study used a validated mathematical model, which predicts the effects of sleep loss and caffeine on psychomotor vigilance task (PVT) performance and combined it with a computationally efficient optimization algorithm to determine when and how much caffeine to consume to safely maximize alertness during sleep loss.

 

The algorithm takes a user-provided sleep/wake schedule and maximum allowed caffeine as inputs and provides a caffeine-dosing strategy as the output.

 

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.

Compared to the original dosing strategies used in the studies, the U.S. Army's algorithm identified strategies that enhanced neurobehavioral performance by up to 64 percent, or reduced caffeine consumption by up to 65 percent.

 

According to the authors, these results suggest that the algorithm can tailor the timing and amount of caffeine to the particular sleep/wake schedule of each study condition to maximize its benefits.

 

"Our algorithm is the first quantitative tool that provides automated, customized guidance for safe and effective caffeine dosing to maximize alertness at the most needed times during any sleep-loss condition," said Reifman.

Always if one shot of espresso  don't work i drink 2 and i'm good to go . Too hot right now to be drinking full cups of coffee that don't have much kick too it if you know what I mean . espresso  beans are much more potent .

coffee makes the world work.... no need for a fancy expensive espresso maker this the one i use

Looks those people from that "academy" has nothing to do in their working time but inventing usless stuff.  It's the a most useless idea I've read lately: An algorithm to determine ideal caffeine dosage

If it's hot, I wait till it cools. If it's cool, I drink it cool. If it's cold I drink it cold. I drink a coffee in the morning, a coffee in the evening and coffee anytime someone offers me  during the day. I don't need any other "algorithm". Period!
