Researchers tested the mood and concentration of 25 women who drank healthy amounts of water one day, and then didn't over the next two days. When slightly dehydrated, the women reported tiredness, bad temper, headaches, and difficulty focusing. In a separate test, men with mild dehydration also had trouble with mental tasks. Scientists are still trying to figure out why.
