Are All Definitions Of Sleep Deprivation The Same
In sleep medicine, sleep deprivation is defined based on sleep duration, which is the total amount of time a person spends asleep. In reality, though, being well-rested is about more than just how many hours you sleep. As a result, the terms sleep deficiency or sleep insufficiency are more frequently used to describe factors that reduce the quantity and/or quality of sleep and keep a person from waking up refreshed.
In this way, sleep deficiency has a broader application. For example, a person who sleeps for a total of eight hours but with many awakenings that fragment their sleep may have insufficient sleep even though their sleep duration technically meets the recommended amount.
This terminology can be distinct from everyday conversation in which the term sleep deprivation may be used with a wider meaning that refers to poor sleep overall and not just total sleep duration.
Even in the medical field, studies may use different technical definitions of sleep deprivation as some classify it as seven hours of sleep or fewer while others use six hours as the cutoff.
What Is Sleep Deprivation Or Insomnia
While many people have heard the term insomnia, Sleep Deprivation is actually a type of insomnia. It is caused by the inability to fall asleep or stay asleep soundly. In its most basic definition, insomnia is the general sleep disorder of either not being able to fall asleep, or waking in the middle of the night and being unable to fall back asleep. Sleep Deprivation is part of the family of insomnia, and the two diagnoses are often used interchangeably. Heres our e-book on tried and tested sleep tips.

What Does It Mean To Be Overtired
The state of being overtired can mean several things. Maybe you havent had enough sleep in a single 24-hour period or you havent had enough sleep over consecutive days for a length of time.
For infants, toddlers, and children, overtiredness could be the result of skipped naps, a late bedtime, or unrestful sleep.
No matter the cause of your overtiredness, it can cause many unwanted symptoms and affect your overall health. Getting a proper amount of daily sleep for your age affects your well-being.
You may experience overtiredness after a single day of not enough sleep, or you may have chronic overtiredness because youre missing out on adequate sleep for a long stretch of time. One term commonly used for overtiredness caused by multiple days, weeks, or years of sleep deprivation is sleep debt.
There are several symptoms of overtiredness, including:
- lack of clear thinking

Causes Of Dream Deprivation
Much has been made of the impacts of sleep deprivation on health. When insufficient sleep is obtained to meet sleep needs, there are real consequences to health and well-being.
Sleep deprivation not only causes sleepiness and the inherent risks, but it seems to wreak havoc on metabolism, pain, and cardiovascular health. What if the same is true for REM sleep loss? How might someone become dream deprived?
First, lets consider the usual structure of sleep. REM sleep normally occurs at regular intervals throughout the sleep period. Every 90 to 120 minutes, REM sleep may occur.
These periods may last 5 to 30 minutes and typically become longer towards morning so that most REM sleep is experienced in the last one-third of the night. It is common to interrupt the last period of REM sleep upon awakening. Frequent disturbance of REM sleep may be experienced as false awakenings.
There are certain situations when REM sleep may be either reduced or absent from sleep. Sleep deprivation due to inadequate total hours of sleep may lead to an absolute reduction in the time spent in REM, but the percentage of the night in REM sleep may actually increase. This occurs because lighter sleep may be eliminated with sleep consolidation.
Substance use has a profound impact on REM sleep. The following are known to suppress REM sleep:
- Antidepressant medications
Your Skin Isn’t Looking Good
Of all the places on your body, your face can truly show your age if you don’t take steps to keep your skin healthy. Those steps include common precautions such as maintaining a well-balanced diet rich in good fats, using UV protection, and perhaps most obvious, getting a good night’s sleep. In a 2014 Clinical and Experimental Dermatology study, experts found that poor sleepers had higher levels of trans-epidermal water loss, thus aging their skin more than good sleepers. Additionally, good sleepers had 30% greater skin barrier recovery, and had a better perception of their appearance and physical attractiveness compared to poor sleepers.
“When a good night’s sleep is hindered, you will look significantly more fatigued,” Flora Kim, MD, FAAD of Flora Kim Dermatology tells Health, citing dark under-eye circles, saggy eyelids, wrinkles or fine lines, droopy corners of the mouth, and paler skin. She says sleep deprivation can also cause occasional acne because it leads to circadian disruption, which translates to an abrupt biological change that creates an imbalance in your skin.

Longest Periods Without Sleep
Randy Gardner holds the scientifically documented record for the longest period of time a human being has intentionally gone without sleep not using stimulants of any kind. Gardner stayed awake for 264 hours , breaking the previous record of 260 hours held by Tom Rounds of Honolulu.LCDR John J. Ross of the U.S. Navy Medical Neuropsychiatric Research Unit later published an account of this event, which became well known among sleep-deprivation researchers.
Claims of total sleep deprivation lasting years have been made several times, but none are scientifically verified. Claims of partial sleep deprivation are better documented. For example, Rhett Lamb of St. Petersburg, Florida was initially reported to not sleep at all, but actually had a rare condition permitting him to sleep only one to two hours per day in the first three years of his life. He had a rare abnormality called an ArnoldChiari malformation where brain tissue protrudes into the spinal canal and the skull puts pressure on the protruding part of the brain. The boy was operated on at All Children’s Hospital in St. Petersburg in May 2008. Two days after surgery he slept through the night.
How Much Sleep Does A Baby Really Need
Babies vary substantially in the amount of sleep that they need, especially during the first year postpartum.
For example, more than half of all 6-month-olds get at least 12 hours of sleep each day. Yet a sizeable percentage of babies who appear to be otherwise healthy sleep substantially less. So merely sleeping less-than-average doesnt mean your baby has a problem .
This Parenting Science article about the opens in a new windownormal range of sleep times in infants may help put your concerns about baby sleep deprivation in perspective.
Still, its possible for things to go wrong, even if your babys total sleep time falls within this broad range of normal variation.
For instance, your baby may take a long time to fall asleep at night, or wake up more frequently than most other babies do. Is this evidence of a problem? Is it something you can improve?
As I explain elsewhere, there are many environmental factors that can contribute to bedtime resistance and frequent night wakings. Read more about these factors and how to fix them in this trouble-shooting guide.
And whether your baby resists bedtime, or wakes up very frequently, you may wonder about our babys personal sleep requirements.
Some babies log as little as 9-10 hours of total sleep time each day, and dont appear to suffer from any health problems. But should we assume that all babies sleeping this little are receiving the optimal amount of sleep? No, we shouldnt.

What Happens When Youre Sexually Frustrated
Well, sexual frustration signs show differently on people. You might take it out on yourself fall into depression, anxiety, or lack of self-control. You might take it out on your partner by resentment, anger, or pressure. Some people even feel the pain or pressure in their sex organs. However, these signs could end up affecting the relationship if not probably dealt with.
How Sleep Effects The Brains Circadian Clock:
Much like the body regulates activities such as eating, drinking and breathing, sleep is regulated by the brains circadian clock . It is estimated that between 8-15% of the gene expression is circadian.
Among other biological activities, growth hormones are secreted while testosterone and thyrotropin are inhibited during sleep. Our circadian clock receives feedback signals from the liver, heart, pancreas, kidneys, lungs, intestines, and even from the skin and lymphocytes. A disruption in circadian rhythm from sleep deprivation can offset the feedback clocks in all of these major stakeholders of health. It must then be of no surprise, that a significant body of emerging evidence indicate that sleep deprivation is a risk factor for obesity, type 2 diabetes and hypertension, and an independent predictor of stroke, coronary heart disease and cardiovascular disease .

Signs & Symptoms Of A Lack Of Sleep
What are the signs of sleep deprivation?
The potential symptoms of sleep deprivation include:
- Daytime sleepiness
- Anger, irritability
- Hyperactivity, particularly in children
What are the effects of lack of sleep? The effects of a lack of sleep are different for everyone. Those with poor sleep habits often experience excessive sleepiness the next day, but children may exhibit hyperactivity.
Lack of sleep negatively affects your performance at school, your job, in social interactions, and on the road. The American Academy of Sleep Medicine reports that 1 in 5 serious car accident injuries is related to drowsy driving.
How To Sleep Better
If youre experiencing mild, occasional problems with sleep, try these simple strategies from sleep expert Michelle Drerup, PsyD, DBSM.
1. Treat getting enough sleep as if it is as important as taking medicine.
With all the demands on our time every day, you might put a good nights rest at the bottom of your priority list. But Dr. Drerup says we need to schedule adequate time for sleep.
Its very easy to stay up late and burn the candle at both ends, she says. However, when you do that, you quickly run into a problem of dealing with sleep deprivation.
2. Keep a consistent wake time.
Wake up at the same time every day, including weekends or days off. Waking at the same time every day will actually help you to sleep better at night. A fixed wake time helps to build a strong desire for sleep throughout wakefulness. This sleep drive gradually builds, and shortening it by sleeping in will make it harder to fall asleep the next night. Sleeping in on the weekend makes it much more difficult to wake up earlier on Monday morning.
It also is important, Dr. Drerup says, to do some relaxing activity such as taking a warm bath or reading a book before bedtime. By making these activities part of your bedtime ritual, you can train yourself to associate these activities with sleep. This association will help you to move more easily into slumber.
3. Put away the smart phones and tablets.
4. If you do wake up during the night, avoid looking at the clock.
How To Prevent And Treat Sleep Deprivation
If you have ongoing or worsening problems with insufficient sleep or daytime sleepiness, working with your doctor is a good first step to getting relief. Your doctor can assess your situation and recommend treatment that best suits your needs.
In most cases, a focus on sleep hygiene your sleep environment and daily habits is a central component of preventing and treating sleep deprivation. The following sections outline some key sleep hygiene improvements for people who get insufficient sleep.
An Introduction To Sleep Deprivation
Due to the highly connected, fast-paced and digital world we live in today, sleeping less has unfortunately become a typical part of our lifestyle. While our sleep choices and patterns can fluctuate from day to day, an ongoing lack of sleep can result in a condition called sleep deprivation.
Consistent quality sleep is as important to our health as daily food, drink and exercise, however this can often be underestimated which can leave us vulnerable to general effects such as fatigue or irritability, as well as more serious medical conditions.
This page is designed to answer all of your questions about the why and how to get sufficient sleep, what sleep deprivation means for you, and what to do in order to restore balance to your sleeping habits.

What Is Chronic Sleep Deprivation
In the simplest terms, chronic sleep deprivation refers to the case of getting insufficient sleep or experiencing sleeplessness over an extended period of time. Chronic sleep deprivation can vary in its severity.
Chronic sleep deprivation may be primary or secondary, meaning that it could be a problem in and of itself or caused by some other unrelated issue .
Accumulated sleep debt can lead to impairments in all areas of your life, and fixing the problem can be difficult depending on the cause. That being said, there are steps you can take to cope with sleep deprivation and ensure it does not lead to more serious issues.
But What Does It Mean To Be Sleep Deprived
One can be deprived of quantity and/or quality of sleep. The National Sleep Foundation recommends that adults get 7-9 hours of sleep while children require a longer quantity of sleep . Significantly less than these quantities of sleep would constitute a sleep disorder.
Shortened sleep duration is defined as less than six hours of sleep while less than four hours of sleep at night is considered extreme sleep deprivation. The National Sleep Foundation also defines quality of sleep as sleeping more time than not while in bed and:
- Falling asleep in 30 minutes or less.
- Waking up no more than once per night.
- Being awake for 20 minutes or less after initially falling asleep.
The symptoms of insomnia include difficulty initiating sleep, difficulty maintaining sleep, early-morning awakening or non-restorative sleep.

You’re Having Trouble Seeing
“When fatigued, you’re not able to control the muscles of the eye as well,” says Steven Shanbom, MD, an ophthalmologist in Berkley, Mich. First, skimping on shuteye tires out the ciliary muscle, which helps your eyes focus. The result: you’ll have a harder time reading up close, he says. Light can also affect the ciliary muscle. A 1999 NIH study showed a strong correlation between children who slept with the light on and near-sightedness later in life. While most adults sleep in total darkness, modern blue-light technology like TVs, computers, and cell phones can also contribute to poor sleep.
Then there’s the extra ocular muscle, which moves the eye from side to side and up and down. “Many people have a muscle imbalance where their eyes don’t track well together,” Dr. Shanbom says, but in a well-rested person the eyes can compensate on their own. A lack of sleep makes the misalignment harder to control, potentially resulting in double vision. You might notice both of these vision problems after one night of poor sleep, but they will persist the less time you spend in bed.
