Whether you drink coffee for the taste or not, one thing all coffee drinkers seem to enjoy is the shot of caffeine energy they get. Josh King has the eye opening details
Perhaps you drink coffee for the smooth, rich taste. Or maybe you crave the surge of energy from a solid caffeine hit. However you take your cup of joe, the stimulant can run riot through your system—speeding up your heartbeat and even giving you the shakes.
But, when taken at just the right time, in just the right dose, coffee can keep you alert when you’re short on shut-eye. Now, U.S. Army scientists have developed an algorithm to harness the power of the nation’s favorite tiredness-targeting stimulant.
“About 40 percent of U.S. Service members sleep less than five hours per night on a regular basis, while the required sleep to fully restore one’s mental acuity is between 7 and 8 hours per night,” Jaques Reifman, a senior research scientist at the U.S. Army Medical Research and Materiel Command at Fort Detrick, Maryland, told Newsweek. “Nevertheless, many military tasks requires considerable vigilance.”
His team wanted to make full use of the “restorative effects” of caffeine to combat the fatigue of sleep deprivation, he explained.
“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,” Reifman said in a statement.
