So Why Did I Bother Researching And Writing This Article On Symptoms Of Sleep Deprivation

Because I think this article can save lives. Maybe yours. Maybemine. Maybe one of our loved ones.

It’s time for everyone to wake up to the reality that sleeploss and sleep debt leads to:

  • An increase in errors
  • Impairment of the attention span

And consider this. Millions of people are sleep deprived all overthe world.

In addition, these same people are driving around tired…AND theyare texting or talking on their cell phones at the same time.

It’s insane!

A New Study Finds That Deep Sleep Is Correlated With Smaller Pupil Size In Mice

    It is commonly known that pupil size fluctuates in response to brightness and darkness during wakefulness. What is less commonly known is that pupil size is also regulated by the autonomic nervous system in response to varying degrees of arousal, brain wave activity, and cortical states.

    For example, during times of distress, “fight or flight” mechanisms of the sympathetic nervous system dilate pupils to optimize vision in the face of potential danger. Conversely, when it’s time to “rest and digest” the parasympathetic nervous system constricts pupil size.

    Through the lens of psychophysiology, increased pupil size is triggered by the SNS as part of an adrenergic system that is fueled by adrenaline. On the flip side, the inhibitory response modulated by the PNS shrinks pupil size and is driven by a cholinergic system, which uses acetylcholine.

    Cholinergic means “relying on or having to do with acetylcholine.” Colloquially, acetylcholine was originally referred to as “vagusstoff” or “vagus substance” because the vagus nerve squirts out acetylcholine to slow heart rate and calm the nervous system.

    The pioneering Swiss study, “Pupil Size Coupling to Cortical States Protects the Stability of Deep Sleep via Parasympathetic Modulation,” was published January 18th in the journal Current Biology.

    Correlation Between Baseline Pupil Diameter And Subjective Sleepiness

    To determine if there was an overall association between the size of the pupil and the level of subjective sleepiness during the 34-h constant routine protocol, all 16 values of all 12 participants were plotted on the same graph. The analysis on raw values revealed no correlation between subjective sleepiness and pupil diameter . In order to reduce inter-individual variability, all future analyses were conducted on normalized data . Indeed, the negative correlation between pupil diameter and sleepiness is illustrated on Figure 2; the higher the sleepiness level, the lower the pupil diameter . In order to separate the potentially different relationships between pupil size and sleepiness during daytime and during nighttime, data were segregated into 4 time-episodes: CR daytime 2 , CR nighttime 2 , CR daytime 3 and CR daytimes 2 and 3 combined . The same correlation analysis was conducted on each of these epochs. No correlations between pupil size and sleepiness were observed for CR daytime 2, CR nighttime 2, nor CR daytime 3 respectively . When CR daytime 2 and CR daytime 3 were pooled together, a negative correlation appeared, suggesting that the time of day is a factor that needs to be taken into consideration .

    When Should You Call Your Health Care Professional About Sleepwalking

    Bloodshot Eyes: Its Common Causes and Prevention

    Sleepwalking usually does not require a visit to your healthcare professional. However, the condition should be discussed with your healthcare professional if sleepwalking:

    • is accompanied by other symptoms,
    • is frequent or persistent, or
    • includes potentially dangerous activities .
    • If you have any history of strange activity or sleepwalking while taking medications for insomnia like zolpidem , you should also speak to your physician.

    This Is An Important Question And There Are Two Parts To The Answer

  • How the symptoms of sleep deprivation affect the way the eyesand face appear.
  • The effects of sleep deprivation on vision.
  • As for appearance, lack of sleep can create:

    • Puffiness under eyes
    • Dryness
    • Bloodshot, red eyes

    I will not cover those symptoms of sleep deprivation in thisarticle. The reason is because the second question I was asked is: Ihave under eye puffiness and also dark circles under my eyes. Do youknow anything that can help with these?

    I do know what can help with thosebags under your eyes and will address that in another article.

    For now, let’s look at the negative effects of sleep deprivationon your ability to see.

    Correlation Between Subjective Sleepiness And Baseline Pupil Size

    Sleepiness increased linearly whereas pupil diameter decreased linearly with time spent awake, revealing an overall negative correlation between the two responses. This correlation between pupil size and sleepiness was previously shown by a number of authors . Similarly, an association between pupil size and vigilance states has also been observed . However, other experiments with frequent pupillary measures did not find this association . The separation of the data according to the time of day revealed a correlation between the two responses during daytime only. This analysis allowed us to observe the changes in the relationship between pupil size and sleepiness, identifying for the first time that the pupil is a marker of sleepiness only at certain segments of the 24-h rhythm and therefore suggesting that their association is not solely linear.

    What Other Sleep Conditions Have Similar Symptoms Of Sleepwalking

    Sleepwalking, night terrors and confusional arousals are all related, common non-REM sleep disorders that tend to overlap in some of their symptoms. Approximately 15%-20% of young children through mid-adolescence will experience some or all of these behaviors. Moreover, seizures occurring during sleep can cause movement disorders during sleeping.

    • Night terrors: Like sleepwalking, night terrors tend to occur during the first half of a night’s sleep – often within 30 to 90 minutes from falling asleep.
    • Also like sleepwalking, they occur during stage III of non-REM sleep. However, unlike sleepwalking, an individual with night terrors will portray sudden and often agitated arousal that may appear to parents as violent and terrifying behaviors. During such an episode, the child characteristically will not be comforted by an embrace from a parent or caregiver.
    • Night terrors often start during the toddler years with a peak incidence between five and seven years of age. During these times evidence of a surge in autonomic nervous system activity is evident. Accelerated heart and respiratory rates, dilated pupils, and sweating is characteristic.
    • Triggers for night terrors may include sleep deprivation, stress, and medications . Unlike sleepwalking, episodes of night terrors may recur for several weeks in a row, abate completely, and later return.
  • Speech is generally coherent .
  • Pupil Size As A Marker Of Homeostatic And Circadian Sleepiness

    The results of our study show that sleepiness and pupil size have opposite linear trends, and reveal that they also follow a 24-h rhythm. The linear trends suggest that the homeostatic component of pupil size could be a marker of homeostatic sleepiness and the 24-h rhythms suggest that circadian variation of pupil size could be a marker of circadian sleepiness. However, the peak of the circadian variation of sleepiness happens around 04:30, whereas the maximum pupil size is observed at 22:30, suggesting that the two circadian rhythms are phase-lagged by approximately 6 h. This large phase difference excludes a causal relationship between circadian sleepiness and circadian pupil size and suggests that they do not drive each other but that they are controlled by separate pathways, both depending on the circadian system. This phase-lag phenomenon between circadian rhythms is not unknown, and is in fact even classical. As an example, although body temperature and cortisol secretion are both driven by the circadian system, their rhythms are not in phase; while cortisol release peaks around habitual waketime, body temperature peaks 9 hours later .

    Death Behind The Wheel: Let’s Look At Some Scaryfacts

    Studies have shown that as little as 18 hours of sleep deprivationimpairs driving performance.

    That means that if you got up at 6 a.m., then by midnight—if youare out driving around—you are a driving hazard.

    Check out these facts.

    In 2010, the AAA Foundation for Traffic Safety put out a reportcalled Asleep at the Wheel: The Prevalence and Impact of DrowsyDriving. Here are just a few of their findings:

    • Car accidents are one of the leading causes of death in theUnited States
    • One in six of fatal car accidents are caused by adrowsy driver
    • One in eight of crashes that resulted inhospitalization were caused by a drowsy driver
    • Over a one month period of time, 25% of drivers admitteddriving when they were so tired, they could hardly keep their eyesopen
    • 41% of drivers at some time in their lives have fallen asleepwhile driving

    What Are The Symptoms Of Sleep Deprivation Dizziness

    When a person is chronically sleep deprived then there are many negative affects occurring in that person’s body, one of which is dizziness. Dizziness caused by sleep deprivation can be felt at any time, especially when standing up. Other associated symptoms of sleep deprivation dizziness are:

    Yawning: Since your body did not get enough sleep, it could not make up for all your oxygen needs, this leads to constant yawning in order to make up for the reduced oxygen level of the body.

    Moodiness: Sleep deprivation may make you irritable. Since the daily quota of sleep has not been met, your body is on a state of unrest, and this will cause you to become moody along with experiencing the sleep deprivation dizziness.

    Fatigue: Of course, if your body did not sleep the amount that is necessary, it will never be ready to face the world. This will cause your body to be tired and respond less to stimulation.

    Irritability: As already mentioned, lack of sleep lowers all your body mechanism. This further leads you to become irritable along with having dizziness.

    Depressed Mood: Depression may be termed as both the cause and effect of sleep deprivation. When deprived of sleep, the body is not able to give you the energy that might be needed to feel refreshed and rejuvenated.

    Forgetfulness: As your body is already fatigued, the mental resources that are required for recollection and memory work poorly which results in forgetfulness.

    What Is The Treatment Of Sleep Deprivation Dizziness

    Treating the dizziness which occurs as a result of lack of sleep, we need to treat the underlying cause of the dizziness, which is sleep deprivation. A person has to be clinically treated when he cannot physically get to sleep either due to physical or psychological reasons. In either of the cases, the patient needs to visit a therapist or a sleep specialist who will be able to offer guidance and coping techniques which will be required to get the amount of necessary sleep. The behavioral and cognitive treatments for treating sleep deprivation dizziness may include:

    Relaxation techniques: Tensing and relaxing various muscles of the body are included in progressive muscle relaxation programs. This helps to calm the body. Besides, other calming techniques involve meditation and mindfulness training. Controlled breathing may also be practiced. Audio and visual recordings are also available that helps people to sleep and hence resolve the dizziness occurring from lack of sleep.

    Stimulation Control: This involves the changing the pre-bedtime activities and the surroundings that might be effective in falling asleep. For example, a person may control stimulation by sleeping in bed only at the time when he or she actually feels sleepy, this enables the person to make a cognitive association of the bed to sleep and hence results in good sleep and treats the sleep deprivations dizziness.

    What Is Pupillometry And Why Does Pupil Size Matter

    Everything You Need to Know About Your Eyes and How to ...

    The measurement called pupillometry is most often used in research and consists of measuring the size of the pupil, which is the central black part of the eye. Not only the size but how the pupil changes, can be meaningful.??

    Pupil size is determined by input from the nervous system acting on the muscles affecting the colored part of the eye called the iris. During periods of rest, or conversely, during periods of activity and arousal, these influences will change. For example, if you are active, your sympathetic nervous system will take over and your pupils will dilate, allowing more information to be taken in.?? If you are about to be eaten by a lion, this system allows you to better spot it before it leaps on you.

    The complementary parasympathetic nervous system will take over during periods of rest and relaxation, causing pupils to return to their default state and become smaller.

    The Early Effects Of Sleep Deprivation On Your Eyes

    You might already be aware that chronic sleep deprivation can lead to obesity, type 2 diabetes, cardiovascular disease and depression, but you may not realize that your vision can also be affected. In addition to common eye problems like dryness and spasms, lack of sleep can cause serious eye diseases. Sufficient sleep is a critical component in the overall health of your eyes.

    The first signs that your eyes are reacting to sleep deprivation can occur after your first overly short night. Symptoms can appear any time you get less than five hours of sleep, as this is the minimum amount of time your eyes need to replenish after working all day. You will notice that you have trouble focusing your eyes, and in some cases, you might have double vision.

    These issues occur because the muscles that control your eyes are exhausted. For example, the ciliary muscle is important for reading. The extraocular muscle is responsible for moving the eye up and down, as well as side to side. When the two eyes are not coordinated, a misalignment occurs. You experience the misalignment as double vision.

    The appearance of your eyes often suffers when you do not get adequate sleep. In addition to the dark circles that are a well-known side effect of sleep deprivation, you can suffer from a burst blood vessel in your eye due to overuse and strain. While this isn’t painful and it won’t permanently damage your vision, it can be an upsetting development.

    Beware These Dangerous Symptoms Ofsleep Deprivation

    No, you won’t go blind or deaf. However, one of the symptoms ofsleep deprivation is vision and hearing problems.

    And as you’ll see below, thiscombination can be deadly.

    Here’s how I found out about this.

    Recently I received two questions fromtwo different visitors to Sleep Passport. Both had to do with theeffects of sleep deprivation on the eyes.

    The first question was: Cansleep deprivation affectyour eyes and vision,and if yes, can you give specific details and examples?

    Can These Effects Be Reversed With Plastic Surgery

    If you’ve been running yourself ragged and can’t get rid of those spots and wrinkles with a sleep binge or two, what can you do? Plastic surgery cannot reverse all of the repercussions of poor sleep habits. However, it can help improve your complexion and boost your confidence when a busy lifestyle has taken its toll.

    • Botox. This simple and non-invasive solution can do wonders for wrinkles and fine lines. It has even proven successful as an acne treatment if insufficient sleep has resulted in a break-out.
    • Blepharoplasty. This procedure specifically targets the bags under your eyes. It typically removes excess tissue from under the eye and smooths out the skin.
    • Face lift. This may be an extreme choice depending on your needs, but it will definitely treat sagging skin. If you find that you’re developing that perpetual frown as noted by the researchers in Stockholm, then this might be your best choice.
    • Medical-grade skin care products. This isn’t really plastic surgery. However, you still might want to consult a plastic surgeon about products that help treat spots, redness and fine lines.

    If you are looking at plastic surgery to keep sleep deprivation from aging you too quickly, remember that there is still no substitute for a good night’s sleep. The best defense against aging will be to address your current concerns while carving out time for 8 solid hours each night.

    Why Do My Eyes Hurt When I Don’t Get Enough Sleep

    When you don’t get enough sleep, your eyes can feel strained, dry and itchy the next day. Lack of sleep can cause eye strain, burst blood vessels and dry eye.

    Our eyes go through a lot during the day. After spending so many hours using your eyes, it’s important for them to get enough recovery time when you’re asleep. Getting enough sleep will give your eyes moisture throughout the night so that they can function properly when you wake up.

    A Relief For You If You Want A Good Night’s Rest

    Here’s a all-natural sleep aid that you might try if you are having trouble getting to sleep. This formula is designed to help you improve your sleep patterns.Neuro-Natural Sleep is packed with 49 ingredients that not only improve how well you sleep, but they improve your overall health also. That’s crucial for getting a great night’s rest.By the way, this supplement does not contain melatonin. That’s how powerful and effective it is.

    This Is Double Trouble For All Of Us As We Age

    That’s because aging, as well as sleep deprivation, lowers ourabilities to process peripheral signals that reach the eye.

    And by the way, another one of the symptoms of both sleepdeprivation and alcohol intoxication is something called end-positionnystagmus. This is rapidinvoluntary movements of the eyes when they are turned to theirmaximum horizontal position.

    When a police officer stopsa person they suspect is driving under the influence of alcohol, theyare trained to look for nystagmus. Sleep deprived people could appearto the officer to be intoxicated.

    Can These Effects Be Reversed With More Sleep

    Sleep Deprivation from 10 Things That Happen to Your Body ...

    Scientific research has clearly demonstrated that sleep deprivation leads to premature aging of the skin. In order to prevent looking like you’re 40 when you’re only 28, you need to get enough sleep. However, science doesn’t appreciate the fact that you have a child, a busy job and a boatload of responsibilities. What happens when you just can’t take the time for more sleep?

    Many people try to get “make up sleep.” In other words, they power through the work week only to sleep extra long on the weekends. These sleep-deprived people hope that as long as they get enough sleep in a given week, their body will forgive them. This is not entirely true.

    To be sure, with more sleep you will experience some improvement when it comes to your metabolism and skin. It’s not like these negative effects on the body are constantly compiling and sending your complexion on an irreversible downward spiral. You yourself have probably noticed that after a few good nights’ sleep, those raccoon eyes start looking a little less worn.

    However, when your next busy work week arrives, you’ll undo all that good again and, over time, the stress on your body from the constant fluctuations will have more lasting aging effects. If it helps, think of the binge and purge sleep cycle as two steps forward and one step back where forward is an older looking you.

    The Effects Of Sleep Deprivation On The Body

    When adults aren’t well rested, there’s more at stake than just a day spent yawning and constantly feeling the need for an extra dose of caffeine. Sleep deprivation can have serious, long-term detrimental effects on the body and the mind. Setting aside mental side effects like delayed reaction times and poor memory for a moment, let’s instead focus on how sleep deprivation affects your face, skin and figure.

    This may come as a surprise to some people, but dermatologist Dr. Jeanine Downie of Image Dermatology in Montclair, NJ notes that many of her patients are “shocked” when she continuously emphasizes the need for sleep for better skin health.

    When asked to expound on the effects of lack of sleep on the body, Dr. Downie cited dehydration and its potential to negatively impact on the skin: “Dehydrated skin is not happy skin, and one of the easiest ways to look like you’re aging poorly is to have dry, crepey or flaky skin.” However, she also notes that hormonal changes brought about by lack of sleep could be of an even greater concern.

    The Effects Of Sleep Deprivation On The Skin

    We’ve already talked a little about how a poor night’s sleep can cause your skin to break out and sag. However, the effects of sleep deprivation on the skin are a little more nuanced than just wrinkles and pimples.

    Sleep deprivation ages the skin, thereby aging you . The lines and blemishes that appear on your skin after a poor night’s sleep are exactly the type that might appear with age.

    In the 2015 Bensons for Beds study, researchers examined a group of 30 women. These women all received a solid night’s sleep before having their faces documented. Researchers counted their wrinkles, pores, brown spots and red blemishes.

    The same women then slept 6 hours a night for 5 nights in a row. Once more, the researchers counted these signs of aging. The researchers concluded that, after sleeping poorly for 5 nights, the subjects had twice the number of wrinkles, dark circles under the eyes and 3/4 more brown spots.

    Eye Health Problems Caused By Lack Of Sleep

    Linda ThomasOctober 5, 2018

    It is not an optical illusion when things get blurry after a night or many nights with little sleep. You may think that you are imagining those funny things. In fact, being grouchy and out of sorts is just one of the results that insufficient sleep patterns can bring to you. Lack of sleep can lead to several problems throughout your overall eye health, including redness, circles, itching, pain, and a number of other things. At Florida Eye Specialists and Cataract Institute, we want you to learn more about how lack of sleep can be problematic for your eyes as well as your appearance, with such evidence as red bloodshot eyes and dark circles.

    According to the Center for Disease Control, the CDC, many workers in the United States are now having less than six hours of sleep a night. The eye needs at least five hours of sleep to be fully replenished. While asleep, important nutrients are delivered to the eye and thus, leave your eyes feeling, and looking, refreshed in the morning.

    SpasmsEye spasms may result from lack of sleep; twitches that are called Myokymia can also be the result. Although these conditions do not cause permanent damage to your eye health, they can be annoying and disruptive as you go about your day after a sleepless night.

    One serious result of lack of sleep is that over time, popped blood vessels may result from eye strain. According to the Mayo Clinic, it can take seven to ten days for the vessel to repair itself.
