The US Army wants you — to drink the perfect amount of coffee

When should I drink coffee to get the best buzz?

Coffee, in a sense, makes the world go ‘round. It comes in different shapes, sizes, colors, and we all consume it however we want, whenever we want. Left, left, left, right, left. That’s my left AND right hand I’m talking about, filling both with caffeine since day one. The more the merrier, right? But why am I crashing at 2 p.m. every day when I’m drinking MORE than enough coffee? The bottom line is that caffeine affects everyone different, and you might be drinking coffee at the wrong time

The U.S. Army, published in the Journal of Sleep Research, recently developed a tool that will tell you how much caffeine you need and when. The reason? To help the military with productivity. Researchers believe this algorithm could lead to a 64% increase in performance while reducing the amount of caffeine consumption by 65% while achieving optimal results. That means drinking less coffee to achieve the maximum level of alertness (Drink less coffee? Excuse me?)

The caffeine-dosing strategy is based on how sleep deprived you are. A mathematical model was used to predict the effects of sleep loss and caffeine on sustained attention and reaction time. Once sleep information is entered, the tool will then advise the correct caffeine-dosing strategy for maximum alertness for that specific individual — advising you how much caffeine you should drink at specific times of the day. 

While the Army intends on licensing this technology, the only public option available right now is the 2B-Alert website, based on similar research. However, without integrating testing performance, 2B-Alert is not personalized. The hopes are that this research will ultimately benefit everyone that needs to get through the day and night.
