Raising Fit Kids: Healthy Nurtition, Exercise, and Weight

  This content is selected and controlled by WebMD's editorial staff in collaboration with Sanford Health Systems.

Sleep has a big impact on health. Kids and teens need enough sleep to help them grow, ward off sickness, think clearly and remember things, and fend off bad moods. Recently there has also been research focused on whether getting enough sleep can help kids keep their weight within healthy ranges. Some studies have shown that kids who don't get enough sleep -- especially younger kids and boys -- may have a greater risk of being overweight.

Though it's still being studied, getting enough sleep has other clear roles in helping kids stay fit. Kids and teens who are well-rested are more likely to have the energy needed for exercise and being active. Additionally, getting enough sleep can help your child learn better and have better memory. When you've gotten enough sleep -- no matter what your age -- you're also more likely to make healthy eating choices. When you're well-rested, you can remember your healthy eating goals and have the energy to follow through by taking the extra moment to choose nutritious food.

But starting from a young age, we want to cram in as much as possible into each day. Who hasn't seen a baby fighting sleep to the point of falling asleep in their plate of food or at play? The trend continues as kids get older and beg to stay up for another TV show. And teens stay online texting friends until all hours if no limits are set.

It's up to you as a parent to encourage enough sleep for kids to help keep them healthy, active, and happy. The trick is to knowing how much sleep kids need based on their ages.
