Summer is a wonderful time for most children, simply based on the fact that they’re out of school for a few months. This free time, however, can equate to lots of time spent outside in the heat. The blistering heat. The unmerciful, unrelenting heat. The sad reality is that a recent study released by the Harvard School of Public Health found that half of our country’s children are not hydrated enough. Their findings are presented below:
More than half of all children and adolescents in the U.S. are not getting enough hydration–probably because they’re not drinking enough water–a situation that could have significant repercussions for their physical health and their cognitive and emotional functioning, according to the first national study of its kind from Harvard T.H. Chan School of Public Health.
The study also found racial/ethnic and gender gaps in hydration status. Black children and adolescents were at higher risk of inadequate hydration than whites; boys were at higher risk than girls.
The study appears online June 11, 2015 in the American Journal of Public Health.
“These findings are significant because they highlight a potential health issue that has not been given a whole lot of attention in the past,” said lead author Erica Kenney, a postdoctoral research fellow in the Department of Social and Behavioral Sciences at Harvard Chan School. “Even though for most of these kids this is not an immediate, dramatic health threat, this is an issue that could really be reducing quality of life and well-being for many, many children and youth.”
Drinking enough water is essential for physiological processes such as circulation, metabolism, temperature regulation, and waste removal. Although excessive dehydration is associated with serious health problems, even mild dehydration can cause issues, including headaches, irritability, poorer physical performance, and reduced cognitive functioning.
The researchers looked at data from 2009-2012 on more than 4,000 children and adolescents aged 6 to 19 years who participated in the National Health and Nutrition Examination Survey, a study of the health of U.S. children and adults conducted each year by the Centers for Disease Control and Prevention. They used urine osmolality–a measure of how concentrated a person’s urine is–to determine whether or not participants were adequately hydrated.
They found that a little more than half of all children and adolescents weren’t getting enough hydration. Boys were 76% more likely than girls, and non-Hispanic blacks were 34% more likely than non-Hispanic whites, to be inadequately hydrated.
Notably, nearly a quarter of the children and adolescents in the study reported drinking no plain water at all.
“The good news is that this is a public health problem with a simple solution,” said senior author Steven Gortmaker, professor of the practice of health sociology. “If we can focus on helping children drink more water–a low-cost, no-calorie beverage–we can improve their hydration status, which may allow many children to feel better throughout the day and do better in school.”
So while we are indeed in the midst of a drought, let’s not neglect our own health needs. Even if watering the lawn is only allowed every other day, let’s water OURSELVES each and every day. Find a fun and/or colorful water bottle that you like, and keep it filled all day. Take it with you everywhere you go! It’s your health; make it fun.
