Drinking water is key not only to keeping the body running well, but Tufts University researchers also find that it is important to keeping us happy as well.
A study of 31 college athletes engaged in an hour of aerobic activity while mildly dehydrated. Compared to counterparts who had had enough water to drink, the dehydrated group reported increased “tiredness, depression, confusion, tension or anger.” While researchers point out that there is some connection between hydration and cognition, they found the strongest relationship between hydration and mood.
Dry eye syndrome has also been connected to inadequate water consumption. To keep your eyes moist and your mood buoyant, be sure to have 6-8 glasses per day.
