US Army Knows The Best Time To Drink Coffee But Won't Tell...Yet

For most people, a good cup of coffee in the morning can mean the difference between a wonderful day and an absolute terrible grouping of 12 or so hours.

Coffee means so much to so many. For some, it's what jolts them awake on a morning, for others, it's what keeps them going throughout the day. A hot and steamy cup of joe could even be used as a pre-workout drink for people who hit the gym on an almost daily basis. And even more importantly, it tastes good.

If you're reading this, you're probably a big coffee drinker. But are you getting your java hit at the correct time? Well, the U.S Army isn't keen on leaving anything— especially alertness— to chance and their scientists have come up with an algorithm to determine exactly when the right time to chug down a nice steamy cup should be, per ScienceDaily.

According to said researchers, coffee, taken at just the right time and in the correct dosage, could improve alertness by a whopping 64 percent under sleep-loss conditions.

"We found that by using our algorithm, which determines when and how much caffeine a subject should consume, we can improve alertness by up to 64 percent, while consuming the same total amount of caffeine," principal investigator and senior author Jaques Reifman, PhD. said in a statement.

The research was presented at the SLEEP 2018 conference in Baltimore earlier this month and it was also revealed that persons who don't like coffee but only consume it for the benefits could reduce their caffeine intake by 65 percent and still improve sharpness by 64 percent.

"Alternatively, a subject can reduce caffeine consumption by up to 65 percent and still achieve equivalent improvements in alertness," Reifman added.

"Our algorithm is the first quantitative tool that provides automated, customized guidance for safe and effective caffeine dosing to maximize alertness at the most needed times during any sleep-loss condition."

The algorithm was built by means of the scientists evaluating caffeine dosing strategies from various sleep loss research and the resulting data was used to mimic the effects of sleep deprivation on participants' ability to perform certain tasks, such as pressing a button as fast as they could when a light appeared on a screen.

As to when the algorithm will be made available to the public, if at all, is still unknown. It is currently being tested on soldiers, but Reifman is understood to want to someday have it available to everyone, from doctors to truck drivers.
