Feeling frustrated? Foggy-headed? Try drinking some water.

June 3, 2010

Most of us have been told that we should drink at least 8 glasses of water per day to keep ourselves hydrated.  There are lots of reasons touted as to why this would be important–to keep our kidneys functioning correctly, to keep our skin looking vibrant and healthy, to prevent constipation, to give us more energy, to lose weight. Now we can add two new reasons for drinking water–to decrease crankiness and frustration and lift our mood and to improve our cognitive abilities.

In a study done by Kristen D’Anci of Tufts University and recently published in Perceptual and Motor Skills, young, healthy athletes participated in a study  of the cognitive and mood effects of mild dehydration (the equivalent to a busy office worker not drinking enough during the day).  The results showed that those allowed to achieve mild dehydration exhibited more anger and frustration as well as a “down” mood after the session than those that maintained their hydration.  Additionally, those who were slightly dehydrated performed much less well on the cognitive tests administered after the session than those that were well hydrated.

So, the next time you find yourself feeling a little foggy-headed or getting easily frustrated with a task, ask yourself when you last had a drink of water.  Getting a glass of water just might make you able to finish that task or project much easier.
