Drinking water in schools.

Children do not drink enough during the school day--and the resulting dehydration contributes to continence problems (Box 1). One important part of treating these problems is an adequate and regular fluid intake during the day (Haines et al, 2000). However, it is not uncommon for pupils to go six or seven hours without a single drink, and those who do drink usually drink less than they need (Almond, 1993; Haines et al, 2000).
