No matter who you are, where you live or what job you do – we’re willing to bet you have one thing in common with millions of other people around the world.
You start with a day with a nice, hot cup of coffee or tea.
Tea and coffee are two of the most popular beverages in the world.
It’s estimated that over 400 billion cups of coffee are consumed every year!
And no wonder – there’s a lot to like. But for most of us, it’s the caffeine.
Caffeine is a powerful stimulant that provides a quick energy boost.
Caffeine has also been shown to increase the production of a certain hormone that helps protect against type 2 diabetes.
Caffeine may reduce the risk of Parkinson’s Disease, liver cancer, liver disease, multiple sclerosis, colorectal cancer, AND heart failure.
But here’s one that might interest you even more – especially if you keep forgetting where you put your car keys.
Caffeine may help to sharpen your short-term memory.
Researchers have found that the caffeine in coffee can increase activity in the frontal lobe of our brain, the part that’s responsible for our working memory.
To test this, researchers took people who didn’t usually drink caffeinated products and gave half of them a caffeine tablet, and half a placebo.
The participants were then given a series of images to study.
The next day, those who had taken the caffeine tablet were able to remember more of the images than those who took the placebo.
In a similar study, a group of volunteers went 12 hours without caffeine and were then randomly given either coffee or a placebo.
Then were given a sequence of images to view, followed by another set, and asked which ones they recognized.
Those who had had caffeine were more likely to show improved short-term memory skills and reaction times in the task.
Using functional magnetic resonance imaging (fMRI), researchers found that these people had increased activity in the parts of their brain associated with working memory.
They also experienced better function in the anterior cingulum, the part that controls attention.
This amazing result appears to have a lot to do with the effects of caffeine on the brain.
The part of our brain used for short-term memory function also controls our ability to prioritize information in order to manage tasks efficiently.
At the same time, it helps us plan new tasks and organize stored information.
For example, when you’re given someone’s phone number in a message, it’s your short-term memory that retains that information long enough for you to enter it on your dial pad.
As you know, a cup of coffee helps to “wake you up.”
Scientists say that this effect improves your attention span and ability to focus – which in turn helps us to store details.
But there’s more to it than that.
