Remember to adjust your clocks one hour ahead on Sunday, March 9, to switch to Daylight Saving Time (DST). Sleep is important to your overall performance; losing just one hour can affect it. You don’t have to feel that loss if you prepare to spring forward:
- Adjust your bedtime. This can help you accommodate losing an hour of sleep. For example, if your bedtime is 10 p.m., try going to sleep earlier the week before so that you can handle the time change when it arrives. You can do this gradually by adjusting your bedtime in 15-minute increments each day leading up to the time change.
- Take a nap. Naps can help make up for sleep debt. If you are not fully adjusted when Sunday arrives, remember that it’s okay to use naps to adapt to your new schedule.
- Re-set your sleep habits. If you’ve thought about improving the quality of your sleep, this may be a great time to re-set your sleeping habits.
- Check DST observances. If you are travelling or deployed, remember to check if the state or country you’re in observes DST or if they do so on a different day. Arizona, Hawaii, and some other U.S. territories do not.

Getting an extra hour of sleep is a dream come true for many of us. For others, the end of Daylight Savings Time means an extra hour on the town or time to catch up on a to-do list. No matter how you choose to spend your extra hour, the amount of sunlight typically decreases over the following weeks, depending on where you are in the world. The change in daylight may influence your outdoors activities, so take this time to make a plan for how to remain active in the upcoming “dark days” of Standard Time.
Plan ahead for outdoor activities in the dark:
- If you jog or hike outdoors in the morning or evening hours, wear reflective or light-colored clothing to be easily visible.
- Plan your route ahead of time and let someone know when and where you will be exercising.
- Have a cell phone handy in case of emergencies.
- Be vigilant. A head-mounted flashlight can help you see holes and debris in your path to avoid sprains and injuries. Also beware of animals that might spook as you pass them in the dark.
- If you must wear earphones, only use one ear bud.
- Bring a buddy or pet!
Plan fun activities indoors:
- Move your exercise routine indoors. Whether in the gym or at home, there are plenty of ways to stay active. Try High Intensity Tactical Training (HITT) for a vigorous workout. Or take this time to give yoga a try or deepen your practice.
- Plan activities that get the entire family involved. Even if you don’t have a gaming console, you can try dancing, hula hoop, or a jump-rope contest. HPRC has more family fitness ideas you can try.
- Finally, think about how much sleep you usually get. Do you get the recommended seven to eight hours every night? This extra hour might be the jumpstart you need to begin prioritizing sleep. For more information on sleep tips, check out HPRC’s Sleep Optimization section.
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.
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 "The impact of sleep loss on total fitness"). 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.
