When should we drink coffee?

Many people in Germany like to drink coffee frequently. Such people will surely say that there is never a wrong time to consume coffee. U.S. researchers Army have now found that there is actually a right time when drinking coffee is most effective.

The scientists of the U.S. Army Medical Research and Materiel CommandFort Detrick developed a computer algorithm that examines sleep patterns and then makes recommendations on how to use coffee. According to the experts, there is an optimal time to achieve the most effective effect. The doctors published the results of their study in the English-language journal "Journal of Sleep Research".

Algorithm gives recommendations for the consumption of coffee

The United States Army researchers have developed an algorithm that gives personal recommendations for timing your caffeine consumption so that you only need to drink a minimal amount of coffee to achieve the desired alertness. The scientists hope to integrate the algorithm into an existing online tool, which people can then use for personal recommendations.

Subjects were able to improve their alertness by up to 64 percent

The algorithm was able to help the study participants improve their alertness by up to 64 percent without consuming more caffeine than normal, the doctors say. On the other hand, it turned out that people with the right dosage regimen were able to reduce their caffeine consumption by up to 65 percent and still achieve the highest levels of vigilance, the study authors further explain. The researchers reached this conclusion by inserting their algorithm into an existing computer model. This predicted how sleep deprivation, schedule, and caffeine affect wakefulness at different times of the day.

How much caffeine to take when?

The algorithms developed make it possible to determine at an individual level when and how much caffeine has to be taken in order to achieve the desired performance at the desired time, says study author Jaques Reifman from the U.S. Army Medical Research and Materiel Command at Fort Detrick.

Algorithm to be integrated in online tool

The new findings are used to improve the vigilance of U.S. soldiers. Army raise. The research team plans to integrate the algorithm into an existing online tool (2B alert). Currently 2B-Alert predicts that attention is based on how much caffeine a person has ingested and how long they have slept. The experts hope to add the algorithm to the online tool before the end of the year. This could help users of the tool to determine the optimal time to consume coffee.

Algorithm especially useful for students

Students could also use the algorithm to determine the best time to consume coffee and to be as attentive as possible during their exams, the doctors say. However, until everyone can use the algorithm, there are other ways to increase attention, such as physical training. A 2011 study found that people who exercise 150 minutes a week sleep better and are less tired during the day. (as)
