Dehydration Could Make Your Mood Worse, Study Shows

Posted: Updated:

Jennifer Aniston made a comment last year that she "gets cranky" when she doesn't drink enough water, the Arizona Republic reported. And now a new study shows that there may be some science behind it.

A new, small study of 25 women suggests that being dehydrated can take a toll on women's mood and cognitive function.

In the study, published in the Journal of Nutrition, researchers found that dehydration was a key factor in causing headaches, loss of focus, fatigue and low mood while exercising and resting, TIME reported.

TIME also pointed out that the women in the study weren't severely dehydrated -- just about 1 percent lower than their optimal hydration levels.

In 2009, a study conducted by Tufts University researchers showed that dehydration leads to fatigue, confusion and a negative mood among young female athletes.

The U.S. Agricultural Research Service, which helped to support that study, explained in a release:

The level of mild dehydration (losses of between 1 percent and 2 percent) experienced among participants in the study could be compared to the mild dehydration some people experience in their daily lives from drinking insufficient amounts of water, according to authors.

The research just adds to the evidence that drinking enough water is good for our bodies. Being properly hydrated keeps our body temps regulated and our tissues moist, aids in digestion and helps to remove waste, Everyday Health reported.
