12 Signs of Sleep Deprivation You Need to Know

    12 Signs of Sleep Deprivation You Need to Know

    It’s not rocket science to recognise when you’re overtired. You’re undoubtedly tired, weak, and unproductive. Your under-eye circles may be more noticeable than ever, and your desires may be stronger than ever. According to the National Heart, Lung, and Blood Institute (NHLBI), these traits are commonly related to sleep deprivation, a disorder that occurs when you don’t get enough sleep— but they’re not the only signs that something’s wrong. Experts describe the 12 various indications of sleep deprivation and what you should know about them in this article.

    You’re constantly hungry.

    “If the brain doesn’t get enough energy from sleep, it will often try to obtain it from food,” says Chris Winter, MD, of Charlottesville Neurology and Sleep Medicine in Virginia. When you don’t get enough sleep, your gut produces more ghrelin, generally known as the hunger hormone (although its functions span well beyond regulating hunger). Dr. Winter claims that too much ghrelin causes your body to seek fatty and sugary foods. In addition, a 2008 study published in the Journal of Sleep Research found that ghrelin levels spiked after just one night of sleep deprivation in the nine “normal-weight healthy men” who took part in the study. Leptin, the satiety hormone, can also be affected by lack of sleep. “When you don’t get enough sleep, you tend to consume more of what you want because you don’t get the signals to stop,” Dr. Winter explains.

    You’ve put on weight.

    Weight gain is another unpleasant sign of sleep loss that occurs along with an increased hunger. “You don’t watch what you eat when you’re fatigued,” Dr. Winter explains. “You look for anything that would make you feel more alert.” Your body will seek fried meals and sweets to get you through the day if your ghrelin and leptin levels are already out of whack—a certain way to expand your waistline. According to Dr. Winter, a lack of sleep can have a direct impact on your metabolism, which slows down when you don’t get enough sleep. Furthermore, according to a 2012 study published in the Annals of Internal Medicine, just four and a half hours of sleep for four days straight can lower your fat cells’ ability to respond to insulin, the hormone that regulates energy, by 30%.

    You are more rash.

    When people are tired, they act without thinking, according to Gail Saltz, MD, Health’s contributing psychology editor. “It becomes increasingly difficult to say, ‘No, I shouldn’t have another candy bar.'”

    This isn’t limited to eating more; you may also find yourself doing or saying things you don’t mean, such as yelling at a spouse or ranting at a coworker. “The most important thing is that you’re less inhibited,” Kelly Baron, PhD, a clinical psychologist with a focus in behavioural sleep medicine, tells Health.

    Because sleep deprivation increases your impulsivity to negative stimuli, you react before you’ve fully processed the event or information in front of you, according to study. The effects of sleep deprivation on impulse behaviour in men and women were investigated in a 2007 study published in the journal Physiology & Behavior. Researchers discovered that patients with impulse control difficulties frequently reported sleep issues, and that lack of sleep impacted cognition, decision-making, and changed how people valued risk in healthy people. Sleep-deprived women’s risk-taking reduced, but sleep-deprived men’s risk-taking stayed unchanged.

    Your memory is shattered.

    Your parents knew what they were talking about if they urged you not to stay up late the night before a big test when you were a kid. Sleep deprivation has been shown to have a deleterious impact on memory function in studies.

    Overtiredness, in particular, prevents protein synthesis in the hippocampus, which is responsible for memory, learning, and emotions. Sleep deprivation causes oxidative stress (an imbalance between free radicals and antioxidants in your body), which further hinders learning and memory functions, according to a 2012 study published in the journal Behavioural Brain Research. Vitamin E, a powerful antioxidant, was shown to mitigate the harmful effects of sleep deprivation on memory performance by these specialists (also referred to as chronic sleep deprivation-induced cognitive impairment).

    All of this is to say that if you want to improve your memory, you must get enough sleep.

    You’re having difficulty making choices.

    Lack of sleep could be to blame if you’ve been finding it more difficult than normal to handle projects at work and at home. According to Baron, “sleep deprivation can decrease speed and higher-level cognitive processes.” Essential activities such as problem solving and time management become even more difficult to perform as a result.

    In a 2009 study published in Sleep, researchers challenged sleep-deprived and well-rested volunteers to complete a set of activities requiring fast decision-making twice. The accuracy of individuals who did not get enough sleep dropped by 2.4 percent between tests, whereas the rested group increased by 4.3 percent. Simply put, lack of sleep makes it difficult to react swiftly and make sound decisions.

    Your motor skills aren’t up to par.

    You might be a klutz if you trip over a step. However, if you do it several times in a day, you may find yourself too fatigued to concentrate on your destination.

    According to a National Institutes of Health study released in 2014, acute sleep deprivation has a deleterious influence on future motor and reversal learning and memory. Dr. Winter explains that “when you’re fatigued, there’s a break in how you neurologically function in general.” Movement becomes more difficult when response time and focus are reduced. “There’s a lot of processing going on when you walk up and down the stairs,” Dr. Winter explains. “You can’t process well when you’re sleep deprived.”

    Your feelings are all over the place right now.

    When you’re sleep deprived, you may feel like your emotions are out of control. “You become overly sensitive to emotional stimuli,” explains Baron. Things that might typically make you sad or angry, such as a tear-jerking movie or a large work deadline, may now cause anxiety, sadness, or fury. (It might also go the other way: “People can feel exuberant and slap-happy,” says Baron.)

    Furthermore, a 2008 study published in the journal Sleep Medicine found that not getting enough sleep not only makes you more emotional, but it also makes you less emotionally intelligent and reduces your ability to think constructively. This implies you’ll be less able to express, control, or even recognise your feelings.

    You get sick a lot.

    Your immune system is another thing that can suffer from a lack of sleep. “If you don’t get enough sleep, your body’s ability to fight infections can suffer,” Dr. Winter explains. You may find it more difficult to recover from a cold in particular. A research published in the Archives of Internal Medicine in 2009 tracked the sleeping patterns of 153 individuals for 14 days. Researchers discovered that persons who slept for fewer than seven hours were nearly three times as likely to catch a cold as those who slept for eight hours or more. That’s because your immune system creates cytokines, which are proteins that help guard against infections and inflammation, while you sleep, so a few nights of bad sleep could weaken your body’s defences against viruses.

    You’re having difficulty seeing.

    “You can’t regulate the muscles of the eye as well when you’re tired,” explains Steven Shanbom, MD, an ophthalmologist in Berkley, Mich. For starters, not getting enough sleep fatigues the ciliary muscle, which helps your eyes focus. As a result, he claims, reading up close will be more difficult. The ciliary muscle is also affected by light. A 1999 NIH study found a clear link between sleeping with the light on and developing nearsightedness later in life. While most adults sleep in complete darkness, modern blue-light electronics such as televisions, laptops, and cell phones can all contribute to sleep deprivation.

    The additional ocular muscle, which moves the eye from side to side and up and down, is also present. “Many people have a muscular imbalance where their eyes don’t track well together,” explains Dr. Shanbom, but the eyes may compensate on their own in a well-rested person. Sleep deprivation makes the misalignment more difficult to manage, potentially leading to double vision. After one night of bad sleep, you may notice both of these eyesight impairments, but they will worsen the less time you spend in bed.

    Your skin isn’t in terrific shape.

    If you don’t take care of your skin, your face will show your age more than any other part of your body. Common measures include eating a well-balanced diet rich in good fats, using sunscreen, and, perhaps most importantly, obtaining a good night’s sleep. Experts discovered that poor sleepers had higher amounts of trans-epidermal water loss than excellent sleepers in a 2014 Clinical and Experimental Dermatology study. In addition, compared to poor sleepers, excellent sleepers had a 30% stronger skin barrier repair and a superior opinion of their look and physical attractiveness.

    Flora Kim, MD, FAAD of Flora Kim Dermatology tells Health that “when a decent night’s sleep is hampered, you will seem much more weary,” noting dark under-eye bags, drooping eyelids, wrinkles or fine lines, droopy corners of the mouth, and paler complexion as examples. She claims that sleep deprivation can cause acne on occasion because it causes circadian disruption, which results in a sudden biochemical shift in your skin.

    People who are sleep deprived are more likely to compensate for their exhaustion by increasing their caffeine intake and/or smoking, both of which can lead to acne flare-ups. Dr. Debra Jaliman, MD, a board-certified dermatologist and assistant clinical professor of dermatology at the Icahn School of Medicine at Mount Sinai, tells Health, “Your body [also] creates collagen when you’re sleeping.” “Getting adequate sleep aids in skin restoration,” she explains. “During this time, the cells renew and DNA repair is increased.”

    You believe you’ve passed out behind the wheel.

    Micro-sleep occurs when you nod off for a few seconds without realising it. “‘I don’t care what you want to do,’ says the brain. We’re going to bed,’ says the group “According to Dr. Winter. It’s your body’s way of pressuring you to get some rest. The main issue is that micro-sleeping while driving can be incredibly dangerous. Drowsy driving was estimated to be involved in 2.2 percent to 2.6 percent of total fatal crashes between 2005 and 2009, according to the National Highway Traffic Safety Administration. If you get too sleepy while driving, pull over and rest until you feel ready to drive again.

    You’re not progressing.

    A good night’s sleep is essential for healthy growth. Because their bodies are experiencing fast growth, newborns sleep a lot in their first few years. According to research, this pattern extends into infancy and adolescence. According to the Nursing Management magazine, children aged 5 to 10 require 10 to 11 hours of sleep, while those aged 10 to 17 require 8 to 9 hours. “While we are sleeping, the human growth hormone (HGH) comes in,” adds Dr. Jaliman, explaining that this is what speeds up skin repair and cell regeneration.

    A 2009 study published in the Journal of Clinical Endocrinology & Metabolism indicates that while sleeping, circulation levels of growth hormones rise significantly compared to awake levels. Lack of sleep causes you to produce fewer growth hormones, which stifles your growth and development. Get plenty of rest if you want to give your growth plates the greatest opportunity possible.
