Get an Energy Boost with This Drink

It quenches your thirst, it's practically free, and it gives you energy to boot. What's this magical energy drink? It's water.

That's right. A new study shows that slight dehydration can send your energy into a nosedive. And it puts people in a foul mood, too. So turn on the tap.

Thirsty, Tired, and Grumpy
When water was withheld from a group of college students who were working out, they reported not just greater feelings of thirst but also more fatigue, anger, depression, and confusion than the group of well-hydrated exercisers. And the researchers suspect that dehydration would probably cause these same side effects in folks who aren't exercising but are water deprived -- although more study is needed to say for sure. Bottom line: Check your fluid intake if you need a pick-me-up. (How much water should you drink each day? Read this article for the RealAge angle on things.)
