Staying hydrated, also known as maintaining proper water balance within the body, is an important concern for parents and their active children during the hot summer months.
Research shows that beverage intake at meals is adequate for keeping your body hydrated, or water-balanced unless there is an increase in physical activity.
Though most Americans believe 8 cups of water will maintain hydration status, this answer is only correct for males 9-13 years of age (see table below). Water needs change with sex and age and they vary due to factors like environment, metabolism and physical activity level. The table below shows the Adequate Intake (AI), or the median intakes of total water reported by a national survey for proper hydration status.
Proper Hydration During the Life Cycle: Total Daily Adequate Intake (AI)
|Age||Daily Amount in Liters (1 Liter = ~ 4 cups)|
|Infants (0-6 months)||0.7 L (3 cups)|
|Infants (7-12 months)||0.8 L (3.5 cups)|
|Children (1-3 years of age)||1.3 L (5.5 cups)|
|Children (4-8 years of age)||1.4 L (6 cups)|
|9-13 years of age||2.4 L (10 cups)|
|14-18 years of age||3.3 L (13 cups)|
|Older than 19 years of age||3.7 L (15 cups)|
|9-13 years of age||2.1 L (8.5 cups)|
|14-18 years of age||2.3 L (9 cups)|
|Older than 19 years of age||2.7 L (11 cups)|
Though the above graph shows an increase in water needs as people age, total water intake is 4 times greater in infants than in adults. There are currently no perfect water intake guidelines for infants and children. The rate of growth and water composition also differ for exclusively breastfed and formula-fed infants, making it hard to define.
When sugar-sweetened beverages are replaced with water, this will result in a decrease in overall caloric intake with no negative benefit on health. Your kids are running around all day in the sun, so what do your offer them to drink? We are here to tell you that water does just as good a job of hydration as sugar-sweetened beverages like Gatorade and PowerAde for exercise less than about an hour and a half, and when paired with the right foods to fuel their fitness. In fact, switching out the sugary beverages for water can lower children’s intake of empty calories by an average of 235 calories and lower their risk for childhood obesity. Empty calories are calories from food with no nutritional value and most of the time end up in body fat production. Say yes to good old-fashioned water and no to childhood obesity. Be aware of how companies market junk beverages to your children and know how to stop it!
There are many ways to decrease the number of sweetened beverages your child (and you!) consume and promote healthy hydration and health. Here are a few ideas to get you started:

Hydration plays a role in physical performance. Dehydration can result in decreased performance of high-intensity and long sustaining activities by reducing muscle strength. Studies show that even small decreases in exercise performance can significantly alter the outcome of an athletic event – remember this at the soccer game half time!
Before you go tell your child to drink up, don’t go overboard. Humans have a built-in system that stops our ability to store water. When a person drinks too much fluid, hormones tell your body to make urine to control fluid balance. If a person drinks too much over a short period of time before this system can take place, it is possible to develop a serious medical illness known as water intoxication or hyponatremia (low blood-salt level). Water intoxication, when your body does not work because it is overloaded with water, is very rare but can be fatal.
