US Army researchers have developed an online tool that suggests how much coffee you should really drink to stay awake. The algorithm is not only meant to help you become more aware of how much caffeine you’re drinking but can also help reduce your coffee consumption.
For the study, which was published in the trade magazine “Sleep”, participants underwent several sleep deprivation and shift work scenarios. Researchers observed how their lack of sleep affected alertness and performance and how much caffeine influenced this.
In some cases, study participants had to stay awake for up to 60 hours and their regular sleeping time was severely shortened. The research team then developed the Open Access tool 2B-Alert Web 2.0 based on these results.
