Drinking water is fundamental for human beings and it is even more important for children especially when they move and “forget” to drink. Now a new study, published in the Journal of Nutrition, underlines this aspect and shows that drinking more water, or in any case drinking the quantity that can be considered sufficient, allows children to be more efficient in multitasking, that is, in the ability to manage or do more things simultaneously, and in general in cognitive abilities.
Researchers from the University of Illinois have indeed studied the effects of drinking water on 75 children from central Illinois. By analyzing children’s urinary hydration and cognitive performance through specific task-switching tests, the researchers realized that children aged 9 to 11 who drank more water not only were more hydrated but showed more reaction times fast in tests and better results in activities designed to measure cognitive flexibility.
Specifically, the researchers made the children drink only half a liter of water a day for four days or 2.5 liters of water a day for four days.
Naiman Khan, professor of kinesiology and community health and lead author of the study, underlines how children are characterized by a higher risk of involuntary dehydration; they often depend on adults to recognize their need for hydration and their daily water supply.
According to Khan himself, this was the first study to measure changes in children’s cognitive performance related to taking different amounts of water over several days.
