Importance of Hydration

How much should children drink?

  • The standard recommendation is at least 6-8 glasses a day, drunk regularly throughout the day (at least 3-4 glasses while at school) ensuring that plenty of additional fluid is drunk during warm weather and/or when exercising."When exercising" means before, during and after exercise and is not restricted to formal PE and games lessons, but is also applicable to active play (e.g. football in the playground or periods of running around). 


What is dehydration?

  • Dehydration is simply not having enough water in your body. It may result from inadequate water intake and/or from losing body water and can develop rapidly or slowly.



How can you tell if children are dehydrated? 

  • Symptoms of mild dehydration can be difficult for teachers to spot. In class some children may become irritable, tired and less able to concentrate. By the time they get home many children are complaining of tiredness or headaches and some may be too lethargic to do anything but slump in front of the television. Although we may think of this behaviour as normal, it is now known that it may, at least in part, be due to the effects of dehydration.  



What are the effects of dehydration on children?

  • The early effects of even mild dehydration are significant for health, well being, performance and learning - and in the long term carry a higher risk of a number of health problems and disease states. 



What effect does dehydration have on the brain?

  • Water makes up about 80% of the brain and is an essential element in neurological transmissions. Poor hydration adversely affects a child's mental performance and learning ability.
