Sure, it helps you feel awake AF but how exactly does it do that -- and what else is it doing to your body?
With a Starbucks on virtually every major city block, it's pretty clear that Americans love their coffee. Real estate trends notwithstanding, a 2013 National Coffee Association survey found that 83 percent of American adults drink an average of three cups a day. That's a whole lot of lattes.
But what exactly is all that caffeine doing to our bodies -- besides giving us that much-needed jolt to get out the door in the morning? Don't worry: We're not here to scare you off the stuff...though introverts may want to steer clear of it during certain crucial life-moments. Here, how our beloved caffeine fix can affect everything from our memory to -- hold onto those coffee cups -- how long we live.
It Boosts Memory
Here's news that will cement a procrastinator's reliance on coffee: In addition to giving those prone to last-minute prep an extra boost of energy, say, the night before cramming for a big test or presentation, coffee also helps enhance memory. A study by John Hopkins researchers found that caffeine can have a positive effect on long-term memory, helping us strengthen recall a full 24 hours after consuming caffeine.
In the study, researchers gave participants a caffeine tablet or a placebo five minutes after having them study a series of images. The following day, the caffeine consumers were more likely to correctly distinguish whether shots in a new set of images were the same or simply similar to the images they had originally viewed.
Now if only coffee could help us forget the memory of all those painful all-nighters we've had to pull.
