Sleep: Your Superhero for Health

November 5, 2025 General /Family

Sleep. Sueño. Sommeil. Sonno. Ngủ. Сон.

No matter how you say it, sleep is important! But in the United States, 1 in 3 adults does not get enough rest, and over 30% of kids and teens aren’t getting the sleep they need.

Sleep is not just “down time.” It helps your body and mind stay healthy. Good sleep can help your appetite, weight, mood, memory, and even safety. Poor sleep can raise your risk for problems like heart disease, high blood pressure, and accidents.

Signs You’re Not Getting Enough Sleep

You may be sleep-deprived if you often feel like you could fall asleep when:

Why Sleep Matters for Kids

Sleep helps the brain learn and remember things.
Deep sleep releases growth hormones that help children grow.
Children ages 2–6 who get less than 10 hours of sleep have a higher chance of becoming overweight than kids who sleep 11 or more hours.
Not getting enough sleep can make kids hungrier, crave more sweets, and overeat.
Kids who don’t get enough sleep may be cranky, sad, or have trouble paying attention.

Sleep and Eating Habits

Not getting enough sleep can make you feel hungrier and crave sugary foods and drinks. A study found that kids who slept one hour less than usual ate more added sugar and drank more sweetened drinks.

What you eat also affects how well you sleep:

Go to bed and wake up at the same time every day.
Turn off TVs, phones, and tablets at least 30 minutes before bed.
Avoid caffeine in the afternoon.
Avoid big meals or alcohol close to bedtime.
Eat a healthy diet and move your body each day.
Spend time outside—sunlight helps set your body’s sleep clock.

How Much Sleep Is Needed?

Age	Hours of Sleep Needed
Newborn	14-17 hours
Infant	12-16 hours including naps
Toddler	11-14 hours including naps
Preschool	10-13 hours including naps
School	9-12 hours
Teen	8-10 hours
Adult	7 or more hours

Encouraging good sleep is one of the best things you can do for your family’s health. It helps kids grow, keeps moods steady, and supports a healthy weight.

Good sleep + Healthy eating + Active play =
A strong foundation for your child’s future.
