Dehydration is a big issue at school for students that many people aren't aware of. Dehydration causes lack of concentration, fatigue, headaches, and many other problems that come along with dehydration. As soon as you begin feeling thirsty your mental performance drops by 10%.

In one school not only did they see an increase in test grades, they also saw a significant decrease in sick days for both the students and the staff!
