The Cost of Sleepless Nights

By: Sarah Bayas

You’re sitting in front of your computer at 3:00 a.m. The only light comes from your glowing screen, and the only sound is the furious clicking of your fingers against the keyboard. Outside, the world is asleep. Inside your mind, it’s chaos—unfinished assignments loom like storm clouds, deadlines swirl like an approaching tornado, and a gnawing voice whispers that you still have so much left to do. Your eyelids droop, your back aches, but you push on. Sleep feels like surrender, and you tell yourself: Just a few more hours. Just a few more.

You wear your exhaustion like armor, convincing yourself that the more you sacrifice, the closer you’ll get to success. But what you don’t realize is that with every sleepless night, you’re chipping away at your strength, your clarity, and your happiness.

And you’re not alone.

In a world that glorifies hustle culture and nonstop productivity, rest is often overlooked or dismissed as a luxury, rather than a necessity. We are constantly fed the idea that the most successful people are the ones who work the hardest, sleep the least, and push themselves beyond their limits. We glorify the entrepreneurs who work eighteen-hour days, the students who brag about sleepless nights, the athletes who “grind” through injuries, and the influencers who post an unrealistic “day in my life” video that begins at 4:00 a.m.— the routine that “transformed their life.”

No, seriously. I wish I was joking. Hundreds of these videos appeared when I searched it up online:

Even worse, well-known figures often publicly credit their success to sleepless nights, arguing that they are more productive the less sleep they get a night. American billionaire and founder of Tesla, Elon Musk, recently boasted that he and his department moved sofa beds into the office and are working long hours and weekends because “that’s when the competition rests,” showing a “hardcore work ethic” (Scott). Musk is also famously known for sleeping under his desk and on the Tesla factory floor to maximize working hours and be more “efficient,” going to sleep at about 3:00 a.m. every night.

Contrary to this unrealistic lifestyle, sleep and recovery are not just passive states of inactivity—they are fundamental to our overall health. In reality, sleep deprivation threatens our mental and physical health, social relationships, and even our lives; but when we implement well-researched sleep strategies and prioritize deliberate rest, we will all become happier and healthier in every aspect.

I remember a time when I fell victim to this threat. Sleep deprivation controlled my life. Maybe you’ve felt it too: the dragging steps, the burning behind tired eyes, the snapping irritation at everyone and everything. I would stumble into morning classes, barely able to keep my eyes open as the professor’s words blurred into meaningless noise. My brain, usually sharp, felt foggy and slow. I snapped at friends over tiny things, forgot deadlines, and found myself spiraling into emotional lows that seemed impossible to climb out of. My workouts, once a joyful way to release stress, became another burden—my muscles refused to cooperate, and it became impossible to get through the entire workout. I thought I was doing everything right. I thought pushing harder meant succeeding faster. In reality, I was sabotaging myself.

It wasn’t until I realized my life was at risk that I forced myself to prioritize rest, and everything changed. The mental fog began to lift. I laughed more easily. I started enjoying my workouts again, feeling stronger instead of drained. I felt like myself again. And slowly, I realized: success doesn’t come from running yourself into the ground. It comes from taking care of the engine that carries you.

The science backs this up. According to the Harvard Medical School Division of Sleep Medicine, "Sleep and mood are closely connected; poor or inadequate sleep can cause irritability and stress, while healthy sleep can enhance well-being" (Harvard). When you cut sleep short, you’re directly impairing your ability to function mentally at even a basic level. During deep sleep, the brain actively clears out waste proteins that accumulate during the day. Without enough sleep, those toxins build up, making everything—studying, conversations, workouts—feel like trying to sprint through deep mud. Dr. Brianna Varas, a board-certified pediatrician who completed her training at NYU, the University of Miami, and Nicklaus Children’s Hospital, is a strong advocate for getting proper sleep. In an interview I conducted with her, Dr. Varas expressed that “without time to rest and recuperate, your body starts to lead to increased stress levels and production of the cortisol hormone, which is the body's response to stress.” Consequently, she warns, cortisol elevation makes it extremely difficult to regulate your mood as well as your ability to handle stressful situations in a common, controlled manner (Varas). As reflected in the figure below, it then becomes a vicious cycle, and could lead to a hormonal imbalance. Furthermore, Harvard’s Division of Sleep Medicine indicates that "sleep helps to 'reset' the brain to prepare for emotional challenges the next day" (Harvard). Essentially, without enough sleep, the brain’s emotional centers become hyperreactive, while the rational centers that help regulate emotions are weakened. It’s no wonder that after a night of tossing and turning, small annoyances feel overwhelming and everyday stresses seem impossible to handle. Imagine waking up after barely sleeping, feeling like the world was heavier, darker, and harder to face.

Rest isn't just a mental necessity—it is a physical one. According to the Center for Disease Control’s Sleep Health Education Program, consistent, quality sleep is critical for strengthening the immune system and lowering the risk of chronic diseases like heart disease and diabetes (CDC). These are two of the leading causes of death in the United States, and both are deeply connected to how the body manages inflammation and insulin regulation. Dr. Varas also expressed that the chronically elevated cortisol she mentioned earlier “can lead to negative effects like weight gain, muscle loss, bone thinning, and high blood pressure” (Varas). This makes it clear that sleep deprivation creates a chain reaction that weakens nearly every major system in the body.

This connection between sleep and physical well-being is especially clear in the world of athletics, where performance depends on the body’s ability to recover and recharge. Along with the medical threats sleep helps to avoid, studies from Stanford University on basketball players showed that increasing nightly sleep to ten hours improved free throw accuracy, sprint times, and reaction speed dramatically (Mah et al.). These results highlight how physical recovery directly contributes to performance. In fact, some professional athletes are firm believers of this correlation. In a CNBC interview conducted by reporter Courtney Connley, LeBron James, one of the most decorated athletes in NBA history, reportedly sleeps eight to ten hours per night and takes regular naps. Currently the oldest player in the NBA at 40 years old, he credits sleep for preserving his career longevity and focus, as well as his overall physical health (Connley). James’s approach to quality sleep shows that even at the highest level of performance, sleep is essential and a top priority. It’s a daily necessity for anyone who wants to maintain energy, strength, and physical resilience. Prioritizing rest means taking your health seriously, not just for today, but for the years ahead.

Another thing that must be taken seriously is the negative effect on social life and relationships when sleep is neglected. Chronic exhaustion not only makes you feel grumpy—it actually rewires your emotional regulation. A 2022 study published in Nature Communications found that sleep-deprived people experience up to a 60% amplification in emotional reactivity compared to well-rested individuals (Krause). That means irritations that might have been a small annoyance after a good night’s sleep explode into arguments when you are tired. I’m sure you can remember a time you snapped at your mom over the smallest miscommunication after pulling two all-nighters for exams—saying things you didn’t mean, feeling regret the second they left your mouth. That’s the kind of disconnection that poor sleep fuels. As we analyzed earlier, sleep deprivation makes it harder to regulate mood. Consequently, it makes it harder to see the other person clearly. It raises defenses and shrinks patience. Over time, these moments can chip away at even the strongest relationships. A tired brain is more likely to take things personally, misinterpret tone, or lash out over small inconveniences. Friends might start to distance themselves, unsure of how to handle your unpredictable moods. Family members may feel like they’re walking on eggshells around you, unsure of what might trigger a reaction. What starts as a few sleep-deprived outbursts can quietly become patterns of misunderstanding and resentment. Without enough rest, it becomes harder to show up as your best self, especially for the people who love you most.

And when it comes to romantic relationships, sleep deprivation can quietly unravel intimacy. According to the article “Effects of Poor Sleep on Your Relationships,” poor sleep impairs communication, making it harder to articulate thoughts or understand your partner’s emotions. Sleep specialist Dr. Angela Holliday-Bell explains that disrupted sleep breaks down the connection between the amygdala and the prefrontal cortex—the parts of the brain responsible for emotional control and rational thinking. As a result, partners may overreact to small conflicts, miss each other’s emotional cues, or fail to communicate clearly in moments that require compassion and calm. Even more concerning is the decline of empathy. Without enough rest, it becomes harder to tune in to your partner’s needs or express gratitude, which can lead to feelings of distance, resentment, or being misunderstood (Eleff). Over time, this disconnection can damage relationship satisfaction. You might not even realize the problem started with sleep—but the emotional fallout becomes impossible to ignore. As a result, it becomes evident that sleep deprivation doesn't just hurt your body, but it sabotages your connections with the people you care about most.

Speaking of losing people you care about, it is important to consider the direct life-threatening effects sleep deprivation can have. People think that a lack of sleep has no urgent, deadly consequences. Some might argue, of course, that there are "high achievers" who famously sleep little—like Elon Musk—and that you can “train” yourself to survive on low sleep. But the truth is far more complicated. Matthew Walker, renowned University of California Berkeley neuroscientist and sleep expert, author of Why We Sleep, notes, "Rare individuals who can survive on less than six hours of sleep without impairment make up less than 1% of the population" (Walker 126). Yes, chronic sleep loss causes almost invisible damage: emotional and physical challenges, higher cortisol levels, and damaged relationships. These effects might slowly grind away at long-term wellness, but what most do not realize is that sleep deprivation can cause fatal accidents. Believing that you can "train" yourself to need less sleep is not only wrong; it is dangerous.

Everyday tasks—driving, taking tests, even basic conversations—become riskier and harder when rest is sacrificed. According to the National Highway Traffic Safety Administration, about 100,000 motor-vehicle accidents are related to drowsy driving annually, resulting in hundreds of deaths every year (NHTSA). The National Sleep Foundation reports that drowsy driving can be just as dangerous as drunk driving in terms of slowed reaction time and impaired judgment. Research shows that sleep deprivation can mimic the effects of alcohol in the brain. Dr. Dustin Cotliar, a sleep expert and emergency medicine physician, explains that being awake for 17 hours can impair your performance as much as having a blood alcohol content of 0.05%, and staying awake for 20 hours brings it closer to 0.08%—the legal limit for intoxication (National Sleep Foundation). Even if you don’t actually fall asleep behind the wheel, that level of impairment can be just as dangerous.

Drowsy Driving (National Sleep Foundation)

One high-profile accident is the 2013 Metro-North train crash in the Bronx, which killed four people and injured dozens. Investigators found that the conductor was severely sleep-deprived due to undiagnosed sleep apnea and recent shift changes, both of which impaired his alertness and ability to respond (Somnology). Long-haul drivers and people driving during late-night or early afternoon hours are especially vulnerable to accidents such as these. Another field at high-risk for sleep-related accidents is the medical profession. Even with regulations in place, residents and physicians often work long, grueling shifts that push them beyond safe levels of alertness. Although the Accreditation Council for Graduate Medical Education limits resident work hours to 80 per week, some still report working as many as 120 hours. According to an Institute of Medicine report, medical errors cause an estimated 44,000 to 98,000 deaths each year—a number that raises serious questions about how fatigue is handled in healthcare settings. Sleep-deprived physicians are more likely to experience slowed thinking, poor memory, impaired judgment, and decreased motivation, all of which can lead to serious or even fatal mistakes during patient care (National Library of Medicine). However, Dr. Varas is confident in a positive shift regarding this issue. Contrary to the older generations in the practice, who prioritized performance over sleep, she believes that “today, the medical world is placing greater emphasis on resident sleep, introducing limits on consecutive work hours to reduce cognitive decline and prevent poor decision-making. It’s encouraging to see that more people are now paying attention to the growing body of research in sleep science” (Varas). The truth is, even the most well-trained medical professionals are still human. No amount of education can protect someone from the effects of extreme exhaustion. When doctors are forced to work under these conditions, the safety of their patients, and themselves, is put at risk.

After highlighting the negative effects of sleep deprivation on mental and physical health, social relationships, and life-threatening risks, it remains crucial to note that there might be a solution. In fact, there are many ways to implement strategies that improve sleep quality and habits, which will in turn improve overall health and wellness.

Fixing poor sleep habits requires practical, specific changes. One underestimated strategy is napping, but it has to be done correctly. According to the Mayo Clinic, naps of about 20–30 minutes can improve mood, alertness, and performance without the grogginess that comes from longer naps. Strategic napping—early afternoon, short, consistent—can become a secret weapon for recovering from sleep debt without disrupting nightly sleep cycles. Short daytime naps can provide a surprising range of positive effects for healthy adults (Mayo Clinic).

When used thoughtfully, naps can lead to:

Relaxation, helping reduce physical and mental stress.
Less tiredness, giving the body a refreshing energy boost.
More alertness, improving focus for the rest of the day.
Better mood, helping regulate emotional ups and downs.
Improved performance, including quicker reaction times and sharper memory.

However, even with these benefits, napping isn't the right choice for everyone. Some people experience sleep inertia—a heavy, groggy feeling after waking that makes them even less productive. Others might find that even short naps throw off their nighttime sleep, making it harder to fall asleep when it matters most. The Mayo Clinic also warns that for individuals struggling with insomnia or poor sleep quality, daytime napping could actually make nighttime sleep worse. Instead of treating naps as a cure-all, it's smarter to see them as a strategic tool—something to be used carefully and consciously. Being aware of how your body responds, how naps fit into your broader sleep schedule, and whether they help or hurt your long-term rest is essential for using naps in a way that truly supports your well-being.

Another powerful but often overlooked factor is nutrition. Tiny choices, like what you eat before bed, can quietly shape how easily your body winds down. Red grapes, for example, naturally contain melatonin, the same hormone your brain produces to control when you feel sleepy. Grabbing a handful of red grapes in the evening, instead of heavy snacks or late-night caffeine, can gently nudge your body toward rest (National Library of Medicine). Dr. Varas, in her interview, suggested to “limit caffeine in the afternoon as it can remain in your system for 6 to 10 hours and delay onset of sleep” (Varas). It might not feel like much at the moment, but small habits like this add up. Sleep isn’t just about what you do at night; it’s built all day long, through every decision you make. The foods you choose, the routines you create—they’re all part of taking care of yourself in ways that actually last. Building a life that feels good doesn't happen by pushing harder and harder—it happens by learning how to listen to what your body has been asking for all along.

Finally, repairing a broken sleep schedule requires patience and planning. Experts at the Center of Disease Control recommend shifting bedtime earlier by just 15-minute increments each night rather than trying to overhaul it all at once. Keeping a consistent wake-up time, including weekends, is even more critical than bedtime. Exposure to morning sunlight, limiting screen time an hour before bed, and building calming evening routines can all contribute to slowly restoring a healthy circadian rhythm (CDC). Dr. Varas also urges to “avoid screen time one to two hours before bed, as blue light can decrease melatonin levels” (Varas).

How much sleep we need changes as we grow, but the consequences of poor sleep follow us at every stage of life. As the chart below shows, newborns need up to 17 hours of sleep a day, but even healthy adults should be getting between 7 to 9 hours each night to function at their best. Yet for many people, those hours slip away without realizing how much they matter.

The daily recommended hours of sleep you need changes as you age (CDC).

Imagine a version of yourself that doesn’t rely on caffeine to survive the morning. A version that handles stress with grace, that laughs easily, that feels genuinely alive instead of just barely functioning. That version of you is not the reward for grinding harder; it’s waiting for you on the other side of real, intentional rest. It’s time to let go of the toxic myth that exhaustion equals achievement. It’s time to honor rest not as a luxury, but as the foundation for a stronger, healthier, more fulfilling life.

However, that being said, it is crucial to emphasize not being so hard on yourself. As more people begin to take sleep seriously, there’s also been a rise in what's been called “sleepmaxxing”—an obsessive attempt to perfect every aspect of one’s rest. The New York Times reports that this pursuit can sometimes backfire, creating anxiety and even worsening sleep quality. Sleep experts have coined the term “orthosomnia” to describe people who become so fixated on getting ideal rest that they actually lose sleep over it. Dr. Milena Pavlova, a sleep physician, explains that sleep “is to be protected, not forced” (Lindsay). The truth is, resting well doesn’t mean doing it perfectly every night. It means doing your best, listening to your body, and giving yourself grace on the nights it doesn’t go as planned.

And let’s be realistic here. I’m a college student. I’ve been a student my entire life. I won’t sit here and act like I’ve got it all figured out. To be completely transparent, I pulled an all-nighter perfecting this paper to the best of my ability. I am probably going to suffer from a pounding headache the rest of the day, but maybe I’ll take a strategic nap and eat some red grapes before bed. Sometimes, if I really have to, I’ll sacrifice my sleep for success in school and making deadlines—but the difference is I don’t make it a habit. It’s more of an emergency-only thing.

Does that make me a hypocrite, considering my entire paper suggests the opposite? Who knows? Just know, nobody is perfect.

So yeah, maybe I did write this at 3:00 a.m.—screen glowing, deadlines looming, brain buzzing. I know that moment all too well. And I also know how easy it is to tell yourself that exhaustion is just part of the process, that you’ll rest when it’s done, when you’ve earned it. That if you keep pushing a little harder and staying up a little later, you’ll finally be enough. But the truth is, the more you trade away your rest, the more you lose the parts of yourself that matter most—your energy, your focus, your joy. Sleep isn’t a weakness. It is your body’s way of fighting for you, even when your mind tries to outrun it. Imagine what could happen if you finally gave yourself permission to rest, not because you earned it, but because you were always worthy of it.

So tonight, instead of scrolling or studying until your eyes blur, give yourself permission to rest. Turn down the lights. Breathe in. Breathe out. Have some red grapes. And as your head hits the pillow, remind yourself: You are not falling behind by sleeping—you’re building a stronger, healthier, more fulfilled version of yourself.

Sweet dreams. You’ve earned them.
