Water... it's simple... but according to a new study it might make you smarter.
FOX's Colleen Cappon explains in this edition of "Housecall for Health":
We know drinking water is good for us, but a new study suggests plain old H2O can make you smarter. Trials at the University of East London found participants who drank three cups of water before taking cognitive tests had higher scores than those who didn't have a drink.
The results add to previous findings that dehydration can decrease mental performance, and water consumption in children may improve memory.
