Coffee – Many of us brew coffee first thing in the morning and begin our daily consuption. The U.S. Army researched the consuption of coffee and found that there is an algorithm we can follow to achieve optimum alertness. The results of the study indicates 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.
