NEARLY two thirds of children are dehydrated when they arrive at school, medics in Sheffield have discovered.
Researchers at The University of Sheffield Medical School studied 452 children aged nine to 11, and found 60 per cent were arriving at school having drunk too little fluid in the morning.
It is the first ever British study investigating the hydration of children. Around 68.4 per cent of boys and 53.5 per cent of girls were not sufficiently hydrated, the researchers found.
They looked at what the children were eating and drinking before leaving for school and analysed urine samples.
The European Food Safety Authority advises boys aged nine to 13 should take in 2.1 litres a day and girls should get 1.9 litres.
Professor Gérard Friedlander, who oversaw the research, said: “We are concerned by the findings of the study. Children are more vulnerable to dehydration than adults due to their high surface-to-bodyweight ratio.
“They also don’t always pay attention to the feeling of thirst so may not naturally ask for a drink.” The research was commissioned by Nestlé Waters.
