A new report shows a growing number of Irish primary school students are tired and hungry going to school.

A study from the Educational Research Centre finds teachers in almost two thirds of national schools say their students do not get enough sleep.

22% say children can't concentrate because they are hungry.

The authors say many parents may not be aware that the average 10-year-old needs about 10 hours sleep a night. 

They blame student fatigue on the fact that 54% of 10-year-olds have a television in thier bedroom and 10% have a computer.
