Can an algorithm tell you the best time to drink coffee? Army tool wants to help soldiers stay alert

Can an algorithm tell you the best time to drink coffee? US Army developer tool to help soldiers stay alert without using too much caffeine

  • The system is intended to indicate the time for the safest, most effective caffeine use
  • It led to an average alertness increase of 40%, which reduced caffeine intake
  • The tool creates a unique dosage strategy for each individual for the best results

Researchers from the US Army have developed an algorithm to perfectly monitor soldiers' caffeine consumption so that they remain alert even when they are not asleep.

And tests of the system so far have shown that it can maximize the benefits of caffeine and even reduce coffee intake.

On average, the team says the tool increases alertness by around 40 percent, which means that participants generally needed 40 percent less caffeine to feel awake.

The open access system 2B-Alert Web 2.0 aims to identify the right moment for the safest and most effective caffeine use.

& # 39; If you pull out an all-nighter, you must be at peak time between, for example, 9 am and 5 pm & # 39; in the evening and you want to consume as little caffeine as possible, when and how much caffeine should you consume? & # 39; Said principal investigator and senior author Jaques Reifman, PhD.

& # 39; This is the type of question that 2B-Alert had to answer. & # 39;

In a study presented in 2018, the researchers had performed psychomotor vigilance tasks (PVT) and indicated their sleep and caffeine intake data.

The algorithm then used the data to calculate a unique dose strategy for each person.

Building on this, the team added a number of other factors to refine the results, including the desired peak alertness periods within a sleep / wake schedule, the minimum desired level of alertness and the maximum acceptable daily intake of caffeine.

& # 39; With our 2B-Alert Web tool, an individual, in our case our service staff, can optimize the beneficial effects of caffeine while minimizing consumption, & # 39; Reifman said.

The tool, which is available online for free, can be used for non-military applications, the researchers note.

Because caffeine works differently for everyone, the results will vary.

However, previous tests show that the method can be effective to improve the effects and to minimize coffee intake.

& # 39; We found that by using our algorithm that determines when and how much caffeine a test subject should consume, we can improve alertness by up to 64 percent while consuming the same total amount of caffeine, & # 39; Reifman said.

& # 39; Alternatively, a test subject can reduce caffeine consumption by up to 65 percent and still achieve equivalent alertness improvements. & # 39;
