This algorithm will tell you exactly how much caffeine you need to stay alert

Ah, caffeine! It's the perfect morning stimulant, but too much can make you nervous and nervous. Have you ever wondered how much you have to stay alert without the negative consequences?

2B-Alert Web

Now, a new web-based caffeine optimization tool, called 2B-Alert Web, can inform you. The algorithm created using several sleep deprivation and shift work scenarios has even been compared to the results presented in the US Army guidelines.

The analysis of the creators revealed that its solutions required an average of 40% less caffeine to remain vigilant or improve their vigilance by an additional 40%.

"Our 2B-Alert web tool allows a person, in our case members of our service, to optimize the beneficial effects of caffeine while minimizing its consumption," said lead researcher Jaques Reifman, Ph.D. ., Principal Investigator at the Department of the Army. for Advanced Medical Technology, serving at the command of research and medical development of the US Army at Fort. Detrick, Maryland.

Reifman already had presented the algorithm at the 2018 SLEEP Congress in Baltimore, the annual meeting of the Associated Professional Sleep Societies LLC (APSS), and compared it to four previously published experimental studies on sleep loss. But, he then decided to push the algorithm even further.

A tool for free access

The algorithm is now integrated with an open-access tool that allows users to enter several other factors, such as the "maximum alertness periods desired in a waking / waking program", the desired minimum level of alertness, and daily intake. tolerable in caffeine. "

This means that the Web 2.0 Tool from 2B-Alert can now predict a person's alertness based on their sleep / wake schedule and caffeine schedule. The free tool also allows users to get the right caffeine timing and doses for maximum alertness.

"For example, if you go out all night, you need to be at your maximum between, say, between 9 pm and 5 pm and want to consume as little caffeine as possible, when and how much caffeine should you consume?" he said. "That's the type of question that 2B-Alert was designed to answer."

The research summary was recently published in an online supplement of the journal To sleep and will be presented at SLEEP 2019.
