Many of us brew coffee first thing in the morning and begin our daily consumption. The U.S. Army researched the consumption of coffee and found that there is an algorithm we can follow to achieve optimum alertness. The results of the study indicate that people’s performance on an attention task can be improved by up to 64 percent. When the algorithm is followed, caffeine consumption can be reduced by up to 65% while still maintaining elevated levels of performance.
As a result of the research, a web-based tool 2B‐Alert Web has been developed to help predict a person’s alertness based on their sleep time and caffeine consumption.
The study “Caffeine dosing strategies to optimize alertness during sleep loss” was published in the Journal of Sleep Research on May 28, 2018.
I don’t drink coffee intending to enhance my alertness these days. I drink it because I simply like the taste. However, if you are in a position where alertness is essential to your job, this may be something to look into.
The 2B-Alert Web 2.0 web tool per their website will:
This software tool predicts the alertness of an “average” individual as a function of sleep/wake schedule, caffeine consumption, and time of day. Optionally, it also provides optimal caffeine schedules for user-provided periods of desired peak alertness. Specifically, it allows users to manually enter a sleep/wake/peak alertness schedule, as well as caffeine dosing and timing, and displays the corresponding predictions for three different statistics of alertness on the psychomotor vigilance task (PVT). If the user provides the desired period of peak alertness, the system will output the estimated optimal caffeine schedules. The tool predicts alertness for the duration of the given schedule and 48 hours of subsequent total sleep deprivation.
This tool can be used to:
- Assess the effect of different sleep/wake schedules and caffeine consumption
- Design sleep/wake and caffeine schedules to optimize alertness
- Generate hypotheses that can be experimentally tested
- Optimize the benefits of caffeine use
