Adults need seven to eight hours of sleep a day, but do you know how much sleep your children should be getting? Pre-school children (ages 3-5) need 11–12 hours a day, school-age children (ages 5-12) need at least 10 hours a day, and teens (ages 13–18) need 9–10 hours a day. But many children and teens are not getting the recommended amounts. For example, The Centers for Disease Control and Prevention (CDC) highlights how almost 70% of teens are not getting the sleep they need.
Don’t know how much sleep your child is getting? Keep a sleep diary to track his/her sleep for two weeks.
Not sure how to help your child get the best sleep possible? Try the following tips. (They’re great for adults, too.)
Make sure your child has a consistent sleep schedule, including a consistent bedtime.
Provide the same quiet, dark bedroom environment for your child every night.
Help your child or teen have a relaxing bedtime routine that helps them prepare for sleep.
Avoid stimulation near bedtime. That means no sodas or other drinks with caffeine* and no TVs or computers in the bedroom.
Exposure to daylight helps set up a sleep rhythm, so make sure your child spends some time outside every day.
Turn the lights down to help your children wind down about an hour before bed and avoid using TVs or computers during this time as well.
Provide a low-stress family environment. Read HPRC’s “Family relationships affect your child’s sleep” for more information.
* Some experts recommend not giving children any caffeine, but if your child or teen does consume some, the American Academy of Pediatrics suggests that children should not exceed 2.5 mg/kg per day and teens should not exceed 100 mg/day.
Did you know that the nature of your family relationships can impact your children’s sleep? Children in home environments with verbal and/or physical conflict do not sleep as well as children in more nurturing home environments. Children exposed to negative family interactions are likely to wake up more, stay awake longer in the middle of the night, and/or sleep less overall.
The conflict can be between parents and children as well as children observing the interactions between their parents. The kinds of behavior include yelling, name-calling, making threats, and physical assault such as slapping or hitting with a closed fist. Behavior like this is often triggered by anger and/or stress, but you can learn to control your anger and reduce family stress, which will help your child’s sleep and a whole lot more. Thus, growing up around nurturing relationships can have multiple benefits.
If you’ve ever thought you noticed a boost in energy while using your electronic gadgets, it may not just be in your head. A recent study suggests that blue light—the type that’s emitted from all electronic devices and energy-efficient light bulbs—can give you an energy boost equal to or better than two cups of coffee. The same study makes a connection between blue light and enhanced sports performance. Sounds great, right? But what if sleep is the missing piece of your performance puzzle?
While you might welcome an energy boost during the day, using electronic gadgets at night can be detrimental to your sleep health, disrupting your natural circadian rhythm by suppressing the secretion of melatonin, a powerful sleep hormone. Follow these tips to manage your exposure to blue light:
- Take advantage of electronic devices during the day to boost your attention, reaction times, and mood.
- Shut off all electronic devices at night at least two hours before you go to bed.
- Consider wearing blue-blocking glasses on those nights when you can’t avoid blue light.
- Use dim, red lights if you like having a nightlight. Red light has less impact on your melatonin levels. (Parents also take note for the nightlight in your child’s bedroom.)
One more tip about light: During the day, get plenty of bright daylight. Not only will it make you feel better during the day, it will also help you sleep at night.
Sleep is essential for optimal performance. Especially Warfighters, though, it can be hard to come by. Lack of adequate sleep, called “sleep debt,” can result in reduced mental and physical performance (see HPRC's "How much sleep does a Warfighter need?"). Use HPRC’s “Sleep & Warfighters” infographic to learn how sleep impacts your health and performance, as well as tips to get your best rest.

On January 14, 2014 the Marine Corps released MARADMIN 010/14, which details the new requirements for the Marine Corps Embassy Security Group. Marines who want to travel the globe and provide security services for U.S. embassies and consulates now have to meet new, revised standards. Among other things, Marines must be at least 64 inches tall so they can adequately view all areas from Post One (point of entry control at diplomatic posts). In addition, physical fitness standards have changed: Marines will have to achieve 1st Class PFT scores. If you haven’t yet achieved this level of fitness, we have some tips. First and foremost, for optimal fitness, be sure to train smarter, not harder.
Misinformation abounds regarding ideal nap lengths for optimal cognitive performance. You need sleep to function at your best. If you do not get the recommended seven to eight hours of sleep a night, then napping can help. Learn more in HPRC’s Answer, “Nap to be at Your Best Mentally.”
That “slow to wake up” feeling of grogginess in the morning has a name: sleep inertia. HPRC asked a sleep expert whether sleep inertia is a real threat to performance, and the answer may surprise you: While sleep inertia is a real phenomenon, the threat it poses to performance has never been seriously studied but probably isn’t as bad as you might think.
However, sleep inertia can be a serious issue when cognitive performance—such as problem solving and decision making—is called for immediately on waking. For example, physicians who are awakened by calls from nursing staff have been known to make serious errors. For most situations, though, it’s better to sleep (and pay down any “sleep debt”) rather than stay awake with the intent of being alert just in case you’ll be called on, our expert concluded.
If your head does need to be in the game quickly after awakening, call on some caffeine to help; it can give you the boost you need to get out of your sleep inertia. Popping in some caffeine gum when you wake up (but only when essential) can produce near-normal cognitive performance within about five minutes.
Sleep is essential for optimal performance! The recent Warrior Resilience Conference V hosted by the Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury included a session called “Scheduling Sleep – A Clear Mind, A Combat Edge,” which highlighted how sleep is critically important to:
- Moral judgment
All of these have a serious impact on performance—not only for Warfighters, but for everyone. Lack of sleep is also linked to increased risk of motor vehicle accidents, depression, substance abuse, weight gain, heart and kidney disease, reduced immune response, and loss of focus. Make it a goal to get seven to eight hours of sleep a night, and reap the performance and health benefits.
Regular physical activity can make you sleep better—but how close to bedtime should you exercise? While the general opinion has been that vigorous exercise within three hours of bedtime might negatively affect your sleep, new research is reexamining this belief. Some preliminary studies have found that exercise before bed (both moderate and vigorous) didn’t negatively impact sleep quality. However, more research is needed to better understand truly how exercise closer to bedtime can impact sleep. Remember—there are many factors that contribute to a good night’s sleep. Just be aware that if you exercise in the evening, it might affect how well you sleep at night. Check out HPRC’s Sleep Optimization section for additional information.
Total Force Fitness requires optimal performance, and optimal performance requires optimal sleep. One way to get your best sleep may lie in some of the subtle sounds you hear every day. You may have heard of “white” noise, a type of random, constant sound that can filter or mask surrounding noises. Studies have now found that another kind of sound—“pink” noise—can help your sleep be even more restful than actual silence. Unlike white noise, the volume of pink noise is essentially the same regardless of its frequency. (For serious audio buffs, here’s an explanation from Georgia State University’s “HyperPhysics” department.) When you think of pink noise, think of rain falling or the rhythm of a heartbeat. This kind of noise regulates and synchronizes with your brainwaves, which enhances the percentage of time you’re in a restful, stable sleep. Pink noise might be another strategy to add to your arsenal for getting better sleep. You can get recordings of pink noise from a variety of sources online—some even free—for your smartphone or other mp3 player or cd/dvd player. A little searching should turn up something you like.
