I am not an expert on sleep disorders or the act of sleeping, but after reading this article it only solidified my opinion on the matter. Sleep is vital not only to the military, but to contractors. A lack of sleep could be a contributor to mental disorders and to poor decision making out in the war zones. Companies would be wise to pay attention to this little talked about aspect of contractor life.
Actually, I would also take it a step further and say that long deployments/contracts are also a contributor to mental disorders and poor decision making out there, because this too is stress on the brain’s processes. But that discussion requires a different post–this post is about sleep.
The article below mentioned some key things that military folks experience as factors for a lack of sleep that also apply to contractors. From drinking Monster Energy Drinks and Rip Its, to playing video games and hanging out on the Internet late into the night, there are many distractions that keep the brain and body awake. Not to mention the day to day combat and operations tempo that both military and contractors experience.
What’s funny is that I found an article on FJ that actually talked about a military program to keep soldiers awake and operating efficiently with little sleep. My commentary on that piece was spot on and I still stand by it. Sleep is vital and it must be a part of the operational planning if possible. To depend on drugs to keep effective is a dangerous path to go down. What I think is smarter is an emphasis on 7 to 8 hours of sleep in this current article, and to me that is the best solution to keep effective.
The other interesting angle on this is that contractors are usually on their own after their shift or whatever, and free to do what they want to do. That means watching a movie, playing video games, working out, going to the range, or just hanging out with the bros. But sleep seems to always be the ‘uncool’ thing to do when it comes to the list of things to do in your off time. I suggest otherwise and you must make sleep a priority.
My sleep goals for overseas contracting are simple. My room or bunk is a place for sleeping. If I have a room, I blacken it out completely, set the temperature gauge to a cool setting, and go to bed at the same time every night (or day for day shift). I always try to shoot for 7 to 8 hours of sleep every time I lay down. Oh and I cut off my caffeine intake and eating about two hours prior to sleeping, or at least try to.
Now for contracts with very little in the way of accommodations or privacy, that is a little tougher. You might be stuck near someone that snores, and if you are a light sleeper, that can be hell. It might be very hot or cold and extremely difficult to just sleep, and especially if you are having to wake up for guard duty at odd hours. All I can say with these scenarios is to ‘build a snowmobile’ and figure out an innovative way to get that sleep. Make a good bed and find a safe but quiet place to sleep. Have a sleep ritual and do whatever it takes to pay your sleep bill. Because if you do not, it will definitely impact your job performance in a negative way out there.
Also, for those of you who are looking for some advice on sleeping, Angela Benedict from the Military Healing Center has some good pointers for you. I posted an article she wrote awhile back on the subject and feel free to contact her if you would like to add some more tools to your ‘sleeping tool kit’. –Matt
Sleep Deprivation and Operational Effectiveness
Military’s Sleep-reduction Program
Lack of sleep could lead to bigger problems for U.S. troops, researchers warn
By SETH ROBBINS
February 5, 2011
Soldiers often find it hard to get a quality night’s sleep when deployed to a combat zone, and doctors think this lack of sleep could lead to long-term mental problems. Some researchers think sleep deprivation could be a cause of the high suicide rate among military members.
Researchers are finding that longtime sleep deprivation can have devastating consequences, including chronic insomnia and psychological disorders.
Especially vulnerable are downrange troops on repeated deployments, experts say.
Army doctors now recognize that sleep-deprived troops can be a danger to themselves on the battlefield, with slower reaction times, fuzzy memories and impaired judgment. But as suicides continue to spike within the military and more servicemembers are diagnosed with PTSD, some researchers and doctors have focused on sleep deprivation as a possible root cause of those issues as well.
Lt. Col. (Ret.) Dave Grossman, a former West Point psychologist who has written and lectured extensively on the psychological impact of combat, is convinced that chronic sleep loss is contributing to the rising suicide rate in the military.
Suicide “is a very complex topic,” Grossman said. “But this chronic sleep deprivation is the new factor, a major new factor.”
Concerns about sleep-deprived soldiers in combat led Army doctors to create new guidelines last year requiring soldiers to get seven to eight hours of sleep each night when downrange. The previous guidelines recommended only half that.
But proper sleep is not easy to come by in combat, no matter what the guidelines say.
Spc. Colin Strook, 25, with the 3rd Squadron, 2nd Stryker Cavalry Regiment in Afghanistan’s Maiwand district, said the longest he’d gone without sleep this deployment was 24 hours.
“I’ve got no problems sleeping,” he said. “I just drink a lot of energy drinks to stay awake.”
While cans of Monster and Rip-It get tucked away on convoys, with troops guzzling three or four a day, research shows that stimulants — such as caffeine, dexamphetamine and modafinil — don’t mitigate all the effects of sleep loss, said Dr. Thomas Balkin, chief of the Department of Behavioral Biology at Walter Reed Army Institute of Research, the military’s leading sleep research center.
Other troops turn to sleep medications, causing the number of prescriptions for Ambien and similar sleep-inducing drugs to spike. In 2004, servicemembers filled prescriptions for sleep medications nearly 70,000 times. In 2009, the number of prescriptions filled by Tricare pharmacists jumped to more than 200,000.
While these medications help troops get a good night’s rest, they are not meant for long-term use.
“None of these drugs,” Balkin said, “is as good as getting a good night’s sleep.”
Grossman, a former Army ranger, talks to troops about sleep deprivation, often peppering his message with anecdotes. World War I and World War II-era troops slept when they were away from the trenches, Grossman explains in the 2008 edition of his book “On Combat.” Other than the occasional beer with fellow soldiers, there weren’t many other ways to relax. Today’s troops, by contrast, return from patrols to well-appointed bases, where they can play video games, grab fast food, watch TV and get online.
Grossman said that he has learned from many noncommissioned officers that soldiers forgo sleep to play video games. Grossman, an occasional gamer, said he believes that games are not inherently harmful, but “all they do is create sleep deprivation and social isolation, which are a guaranteed cocktail for depression.”
Critical effects
Sleep deprivation can be especially dangerous in combat.
It narrows a person’s focus of attention, Balkin said, leaving him or her unable to multitask as efficiently. A sleep-deprived soldier could fire accurately, for example, but his ability to spot a potential enemy, to decide whether to fire his weapon or to locate friendly forces would likely be hampered.
“Virtually all cognitive performance is affected,” Balkin said. “A soldier is set up to make errors when sleep-deprived.”
Balkin is educating senior military leaders on the importance of making sure troops get enough sleep and seeking ways that troops can optimize their sleep by banking extra hours. Soldiers would be forced to sleep more before being put in situations where they were likely to become sleep-deprived. Those who get extra rest, Balkin said, recover and return to a normal sleep pattern faster.
His team is also developing mathematical models to help commanders determine which troops are most vulnerable to sleep deprivation.
“This way,” he said, “a commander can schedule, when it’s possible to do that, soldiers who are in better shape.”
Troops suffering long-term sleep troubles after a deployment, the sleep researchers say, should be a red flag to commanders that they are potentially at risk for other problems.
According to a recent Pentagon study, the rates of insomnia in the Marines and the Army doubled after a deployment.
“It makes sense,” said Dr. Alan Peterson, a researcher who has studied the effect of deployments on sleeping habits. “The noise, the living conditions, the risk of threat are all factors that make it difficult for anybody to sleep. And the longer a person goes with disrupted sleep, bad habits and patterns can set in.”
According to the Pentagon report, the rate of clinically diagnosed insomnia, defined as sleeplessness requiring medical intervention at least twice, has increased twentyfold in the past decade. There were slightly more than 1,000 reported symptoms of insomnia during 2000. By 2010, that number had jumped to 19,851 — with the greatest increase, by far, in the Army, followed by Air Force, Marines and Navy.
Balkin said the exact link between insomnia, psychiatric disorders and suicides within the military still needs to be carefully explored, since sleep disturbances are so common and their causes so varied.
He likened sleep troubles to a thermometer that shows that you have a fever.
“You know there is an infection,” he said, “but you wouldn’t be able to tell what that infection was.”
Insomnia and PTSD
Chronic insomnia has been linked to high blood pressure, obesity, heart disease and diabetes. It can also make people vulnerable to psychological illness and suicide, said Dr. Robert Stickgold, a sleep researcher at Harvard Medical School.
“Psychiatric conditions,” he said, “can be triggered, exacerbated or caused by a sleep disorder.”
Patients with sleep apnea — a condition in which the nasal passage closes over during the night, choking the sleeper — are twice as likely to suffer from depression. When their sleep apnea is cured, Stickgold said, their depression symptoms also lift.
Brain imaging shows that sleep deprivation causes the amygdala, the part of the brain that controls emotion, to become overactive, allowing more negative thoughts and emotions to intrude.
Dr. Anne Germain, a University of Pittsburgh sleep researcher who is scanning the brains of vets with post-traumatic stress disorder to see exactly what mechanisms are at work while they sleep, said that “there is a very strong suggestion that sleep disturbance prior to a traumatic event can increase someone’s risk of getting PTSD.”
Researchers are just starting to unravel the exact relationship between PTSD and sleep. Stickgold said that sleep, especially the dream-rich state called rapid eye movement, allows the brain the opportunity to incorporate memories and shade emotional events.
“You want to let the smell go, the sound of the voices go,” he said, “and keep an abstract memory of the event.”
Stickgold said sleep’s role in memory formation is similar to that of a “psychologist,” helping a person place emotional events into proper context. With proper sleep he said, the memory will recede and integrate into a person’s past — without it, it might not.
In PTSD patients, he believes that adrenaline-like chemicals flood the brain, keeping it from fully entering REM sleep, where the memory of the traumatic event can be broken down and pulled apart.
Instead the event is replayed, as though the person is watching a scene from a movie.
“That’s why you get these guys who say they can still smell it,” he said. “Every day is the day after it just happened.”
Teaching better sleep
When veterans with PTSD start sleeping better, many of their daytime symptoms disappear.
Germain, the University of Pittsburgh researcher, has investigated sleep therapies that eliminate vets’ nightmares, including prazosin, a medication that controls nightmares by depressing adrenaline, and image rehearsal therapy, which teaches vets to refocus the imagery in their nightmares to something less threatening.
The early results are startling, she said, suggesting these therapies can reduce the anger, irritability and poor concentration associated with PTSD.
Dr. Karin Thompson, a psychologist at the Veterans Affairs’ hospital in Memphis, Tenn., and an author of “The Post Traumatic Insomnia Workbook,” has also seen how improving sleep benefits vets with PTSD, especially those with hypervigilance.
In her sleep clinic, Thompson teaches vets methods that will allow them to “reset” their central nervous systems, she said.
She encourages them to set a sleep schedule; to avoid alcohol, which harms the sleep cycle; to wake up at the same time every day; and to begin relaxing one hour before going to bed by taking a bath, for example, or doing yoga. They should not watch television or surf the Web while in bed.
“The bed,” she said, “should be for sleeping and sex only.”

Sleep Deprivation and Operational Effectiveness
By Angela Benedict
It is interesting to me to observe how many people involved in security professions have a warped idea that “being on” at all times of day is some kind of romantic notion. It’s cool to work on 2 hours sleep. Hmmm. What do the Marines say?
” Alertness and performance decline gradually with partial sleep deprivation; that is, when sleep is limited to 4 to 5 hours per night. After 5-7 days of partial sleep deprivation, alertness and performance decline to the same low levels as those following 2 days of total sleep deprivation. After 48 to 72 hours without sleep, personnel become militarily ineffective.” ( Field Manual 6-11C, Combat Stress, 2000)
So fractured sleep has the same result as total sleep loss. This is not a romantic notion. This operational stress trigger puts people at risk.
What can be done to sleep better?
Creating an environment that is conducive to sleep is critical. Blacked out and sound proofed windows help. Ear plugs if they don’t drive you crazy and the sounds of your own body don’t keep you awake are an option. Having a sleep routine is key. This means developing a system of actions that you do repeatedly before you go to bed that signals to you that it is sleep time.
The biggest keys to good sleep are deep breathing exercises before you lay down and visualization of something peaceful when you do lay down. For many people however, they can’t relax enough to do the breathing or visualization.
Journaling can help with the brain clutter that prevents sleep. Try keeping a book beside your bed that you download into. Imagine that someone is timing you and you only have two minutes to empty your mind. That means writing out everything that you’ve kept crammed inside your head all day. Write like you’ll have to do laps if you don’t get it all out. Then when the two minutes is up, sit back, and take inventory. How do you feel? How much more is inside your head? Have you emptied enough that you can sleep? If not, go for another two minutes. Once you get into the practice of downloading, you may find that you want to do this at other times during your day. On your lunch break or first thing in the morning. You can begin your day by emptying out any concerns you have for the day before they take root inside your mind. This helps to keep you objective. To be a successful operator you need to be clear headed.
Self care is critical. If you don’t take care of you, you won’t be much help to anyone else. Getting as much good sleep as possible is part of your self care regime. This should also include deep breathing, meditation, visualization, muscle relaxation techniques, proper diet, exercise and emotional management strategies.
Don’t just take my word for it. USMC says so.
