Water shortage: The facts
Feeling thirsty means a pupil has already become dehydrated.
Brain cells are between 74 and 85 per cent water, and neural connections within the brain are impaired when dehydrated. Cognitive performance decreases by 10 per cent in healthy young adults when they feel thirsty.
A study by Leeds University researchers found that nine out of 10 pupilsconsume less than 75 per cent of their recommended daily fluid intake.
On average, British schools have one water fountain or tap per 80 pupils.
