In the American Journal of Public Health, researchers reported that over 50% of the thousands of children who participated in the study between 2009 and 2012, were at least mildly dehydrated. The researches added that this however did not amount to saying that the kids were seriously dehydrated or ill. However, they said, even mild dehydration can lead to mood swings, problems with ability to learn, and cause fatigue.
According to the Institute of Medicine, teenagers and children should be consuming some 2 to 3 quarts water every day depending on their age, sex and physical build. In the case of adolescent boys their need for water tends to be higher compared to girls according to the researchers.
