Abstract

Water has many physiological functions and is one of the essential substances for human survival and development. It is very important to take enough water and keep adequate hydration state. When children and adolescent are in physical activity, due to the different intensity of physical activity, energy consumption and environmental temperature and humidity, the water demand is also different. The risk of insufficient water intake and dehydration is higher among people in physical activity. However, the importance of water has not been paid enough attention, and the literacy on hydration state and health among children and adolescent needs to be improved. Children and adolescents generally had insufficient water intake and were dehydrated. Existing research showed that dehydration could reduce the cognitive ability of children and adolescents, and the cognitive ability could be improved after health education or water intake intervention. Scientific water supplement or electrolyte supplement and energy drink could help to improve the ability of physical activity. It is necessary to carry out more investigation on behavior of water intake and more researches on hydration state and health impacts among children and adolescent. It is also necessary to carry out water intake related health education children’ s and adolescents’ , so as to improve their the literacy on hydration state and health, and to promote sufficient water intake and reasonably choose on water type, to maintain appropriate hydration state, and then to promote their health.
