In a new study, students
who brought water into exams scored higher than those who didn't. The
researchers believe staying hydrated lowered anxiety and improved thinking
power.
We get it. Despite the
never-ending health benefits, staying hydrated may not top your daily to-do
list. If you can't get yourself to guzzle enough H2O, new findings might offer
extra motivation: Drinking water can boost your brain power.
In a study presented Wednesday at the British Psychological Society Annual
Conference in London, researchers found that students who brought water into
exams performed better than those who didn't. To make sure they hadn't simply
concluded higher-scoring students are more likely to bring water into a test,
they used the students' past coursework grades to set a general ability
control. So even among generally poorer-scoring students, bringing water into
the exams boosted their grades.
"The results imply
that the simple act of bringing water into an exam was linked to an improvement
in students' grades," says Chris Pawson, a professor at the University of
East London and one of the study's co-authors, in a release from the British
Psychological Society.
For those of us who've
graduated from the test-taking world, the same could apply for our cognitive
performance and work productivity, in theory.
Smart Water, Naturally
The researchers don't know
if the students actually drank the water they took into the exams, or how much
they drank, but their presumption is that the test-takers consumed at least
some of the water they brought with them.
And while Pawson and his
colleagues didn't get to the bottom of why water had this effect on
the undergraduates' grades, they have some theories. Maybe water enhances
thinking power, leading to better scores. Maybe agua alleviates anxiety and
stress, both known to hinder exam performance.
Either way, add "it
makes you smarter" to the long list of reasons you should be drinking
water.
It already has a
reputation for regulating body temperature, flushing out toxins, aiding
digestion, balancing blood sugar, and even helping you deal with seasonal allergies,
to name a few.
The easiest way to drink
more water is to have it in front of you. At your desk, keep a big cup next to
your keyboard. (Just don't spill it.)
On the run, always take a
refillable bottle. If the taste (or lack of taste) turns you off, flavor your water with
slices of lemon or fresh fruit.
Now, don't you want to go
take a sip of water? I do.
