Only 5 Hours Of Sleep Its Worse For You Than You Think

Pulling an All-Nighter vs. 2 Hours of Sleep: Which is Worse? â Healthy Living and Diet TipsâSELF

There are many possible reasons why youâre a five-hour sleeper, some by choice and some due to necessity. Perhaps you think you can accomplish more by sleeping less. Or maybe you consider short-sleeping a badge of honor. Similarly, a demanding work schedule or a teething newborn may be whatâs barring you from meeting your sleep need.

The point is, you think you can survive on five hours of sleep . Unfortunately, youâre doing yourself a major disservice and in more ways than you might think. Denying yourself the sleep you need â and accumulating sleep debt in the process â is the surest way to short-circuit every aspect of your life.

Ahead, we show you how only five hours of sleep is synonymous with sleep deprivation and what that means for your waking life.

What Happens After 48 Hours Of Being Awake

After two days of being awake, you will start looking for just about any way to fall asleep. As your body naturally tries to help itself, during periods of idleness, you may just doze off.

These can be quick naps or long snoozes. Or, they can be something called microsleeps. Microsleeps are fleeting moments of sleep, or a sleeplike state, lasting anywhere from 1-30 seconds. They are involuntary and occur frequently throughout the day, even if youre in the middle of an activity.

Not only does this make microsleeps dangerous in themselves a lot of things can happen during 30 seconds of unconsciousness they also leave the person in a disoriented state when they wake up.

Imagine going through these random episodes while in a meeting, on a conference call, or driving. These are all everyday scenarios, made dangerous by the lack of sleep.

Aside from these split-second naps, your body will have difficulty regulating its internal functions as well. Youll experience a dip in both body temperature and metabolism. And when coupled with constant snacking , frequent spells of going without sleep can lead to weight gain and an increased risk of diabetes.

Ultimately, your entire immune system will be compromised, as your body starts shutting down and becoming more vulnerable to bacteria and viruses. By this point, sleep is becoming increasingly crucial.

A few signs of going without sleep for 48 hours include:

  • Extreme fatigue
  • Increased risk of diabetes and other diseases

I Am Here To Challenge Everything You Thought You Knew About Sleep

Ive always needed a lot of sleep. A week before doing this experiment I tried buying myself more time by sleeping just six hours per night.

It wasnt sustainable. In fact, I was so groggy and sleep deprived it had the unintended result of lower overall productivity.

So, naturally I was skeptical when I heard you could sleep just three hours per night with no adverse effects.

But I had nothing to lose. In fact, IF THIS WORKED, I could gain the extra time Ive been seeking for years. So I HAD to try it out.

Here are my experiences and lessons from the most incredible sleep experiment Ive ever tried.

Your Actual Sleep Need Is Definitely More Than Five Hours

If you think you belong to the minority that does well on little sleep â i.e., five hours of sleep â the odds are close to nonexistent. As Dr. Thomas Roth says in Matthew Walkerâs book, Why We Sleep, âThe number of people who can survive on 5 hours of sleep or less without any impairment, expressed as a percent of the population, and rounded to a whole number, is zero.â

Matthew Walker further elaborates, âIt is far, far more likely that you will be struck by lightning than being truly capable of surviving on insufficient sleep thanks to a rare gene.â

Getting only five hours of shut-eye means you arenât meeting your biological sleep need â an individual trait thatâs genetically determined, like your height or eye color. The majority of adults need 7-9 hours of sleep per night to function optimally, with a true average of 8 hours and 10 minutes to prevent neurobehavioral impairment.

Your sleep need may also change as you age. To illustrate, preschoolers average 10-13 hours per night while older adults usually need about 7-8 hours.

What Does Lack Of Sleep Do To Your Brain

Sleep deprivation slows that work down, compromising our mental performance. Less robust brain-cell activity isn’t the only way poor sleep hampers the brain, and our ability to think. Sleep deprivation: Disrupts levels of hormones, including serotonin, dopamine, and cortisol, that affect thought, mood, and energy.

You Arent Using Those Extra 3 Hours Productively

Contrary to your game plan of sleeping less to do more, sleep deprivation prevents you from productively using those extra hours of wakefulness. Matthew Walker explains it perfectly in his book Why We Sleep, “The recycle rate of a human being is around 16 hours. After 16 hours of being awake, the brain begins to fail.” In other words, you think youâre doing yourself a favor with less sleep, but thatâs just not true cognitively, emotionally, or physiologically.

How Long Can You Go Without Sleep An Extreme Sleep Deprivation Case

The longest world record for going without sleep is about 264 hours, or a little over 11 days, made in 1964. The title-holder Randy Gardner, who was an 11-year-old high school student at the time, recalls feelings of nausea, difficulty concentrating, and lapses in memory.

There have been many other cases of people going without sleep. However, a few days seems to be the most common length. And although the time spent without sleep is far from pleasant, the symptoms of prolonged sleep deprivation will usually go away as soon as you get enough rest.

As much as possible, try to go back to a normal sleep schedule. This may be difficult at first, as your sleep-wake cycle has been severely disrupted. But you should be able to readjust and return to your normal functions after a few days. Improving sleep hygiene habits and sticking to a consistent bedtime routine can help you consistently get rejuvenating sleep.

Do Some People Need More Sleep

On the flip side, some people need extra sleep to function optimally. While there’s no evidence of a “long-sleep gene” like there is of the short-sleep one, Miller says she wouldn’t be surprised to hear about such a discovery in the future. “Our sleep need is largely based on genetics,” she says, so it would make sense.

You don’t need a study to tell you how much sleep you need, though. Most adults know how much sleep they need to feel refreshed and energized. If you feel your best with 9 to 10 hours of sleep versus 7 to 8, then you should sleep that much whenever time allows, Miller says.

People should push out the Instagram time and stick to the schedule, she says.

    Respect your rhythm

    Once you determine your natural sleep schedule, staying on track with that internal clock makes all the difference.

    Even if you get 10 hours of sleep, if its not in line with your circadian rhythm, you can actually function like a sleep-deprived person, says Salas. You can add an extra hour or more, but unless youre scheduling it to sync with your natural sleep-and-rise times, you might not actually be getting a proper nights rest.

    Why You Arent Actually Doing Fine On Only 5 Hours Of Sleep

    After one night â or several successive nights â of short sleep , we overrate our ability to stay awake and alert. You probably think, âHey, Iâm actually not doing so bad after all!â. The reality is, youâre actually doing very poorly!

    Here are five compelling reasons to dispel that common misconception, and show you why you aren’t coping as well as you thought:

    Your Brain And Body Are Tricking You

    As humans, we adapt biologically within a few nights of short sleep. You may think youâre doing fine, but in reality, your performance is in decline. In as short as a few days, your subpar energy levels start to feel normal, while behind the scenes, your daytime functioning and overall well-being is subjectively crumbling.

    Another reason why you might not feel particularly tired after a night or several nights of short sleep, is due to a surge in your cortisol levels the next day. On top of that, your circadian rhythm is still marching on in the background, as it operates independently of your sleep drive. High stress levels coupled with your circadian energy peaks allow you to keep functioning even when youâre massively sleep-deprived.

    How Much Sleep Do People Really Need

    Rain at night (no music, no thunder). Ideal for Sleeping, insomnia, Relaxing or Studying (2 hours)

    Sleep recommendations are like water recommendations. No one really knows exactly how much water people need each day, so there’s no single “best” recommendation — the same is true for sleep.

    While most sleep experts recommend seven to nine hours each night, Annie Miller, a therapist at DC Metro Sleep and Psychotherapy, tells CNET that people shouldn’t feel pressured by this number. “Historically, one uninterrupted period of sleep was not always the standard,” she says.

    Our Health & Wellness newsletter puts the best products, updates and advice in your inbox.

    The origins of the eight-hour ideal remain unclear, but post-industrial standardization of school and work schedules is likely to blame. Regardless, the need to conform to this standard “has certainly contributed to many people’s insomnia,” Miller says. “If we feel like we ‘should’ be getting more sleep or we aren’t doing it right, our sleep will suffer.”

    Below Ive collated a list of things that happen when we dont sleep. It doesnt make for fun reading, but its important to know what were missing out on when were pushing ourselves to burn the candle at both ends. And given what sleep scientists have found, you may not even recognize that youre suffering from these right now!

    Getting Through The Day After Little To No Sleep

    Whether you enjoy a power nap or dont sleep at all, youre still going to feel exhausted the next day. To make things a bit more bearable, heres our best advice for feeling energized after a night of little to no sleep.

    • When your alarm goes off, get out of bed, turn on the lights, and open the curtains. Bright light, even if its artificial, will help wake you up.
    • Real sunlight is even better. If you can, go outside and spend some time in the morning sunlight. For an extra energy boost, exercise. Even a brisk walk will activate your body and mind.
    • Throughout the day, eat during your normal meal times to help your sleep schedule stay on track.
    • Avoid overly sugary or fatty foods. Youll be craving them , but youll be less equipped than ever to recover from the sugar crash.
    • Indulge in caffeine early in the morning. Dont overdo it, though, and cut yourself off in the early afternoon. You dont want to end up so wired that you experience another sleepless night.
    • If youre absolutely exhausted, enjoy another power nap. You might even make it a coffee nap. Again, limit yourself to 30 minutes tops to avoid entering deep sleep.

    Also, expect to feel less than great for the days following your all-nighter. The idea of catching up on sleep is a myth.

    Find Something That Interests You

    You might find your body doesnt want to wake up after only a few hours, or minutes, of rest and prefers to keep on sleeping when you are first trying to adjust to this new regimen. Some suggest having a plan for your waking hours that includes projects, hobbies, and skills that you are very important to you.

    This train of thought assumes that your interest will be enough motivation to get you up and moving after your rest period. It may be beneficial to add some variety to your daily activities to avoid becoming bored. Everyman users believe the more interested you are in a subject the more likely you are to adhere to the schedule, and monotony is only likely to get in the way of that.
