We Lose Our Good Looks

Perhaps worst of all, sleep is one of the best ‘tricks’ you can use to look great. And after bad sleep?

We all know the look. Bags under the eyes, dark circles, paler, and just generally worn down. Being tired means you can never give your best first impression to someone new, or look the best for your partner.

This is especially sad since Sleeping.Guide readers are some of the best looking people on the planet. Don’t let late nights ruin your good looks, friend!

Don’t believe me? Here’s a study proving it.

Researchers at Stockholm University asked judges to gauge the appearance of people using pictures of them after a full night’s sleep, and after a bad one. The conclusion was strongly found that a lack of sleep will mean a lack of attention from the opposite sex:

“Our findings show that sleep deprived people appear less healthy, less attractive, and more tired compared with when they are well rested. This suggests that humans are sensitive to sleep related facial cues, with potential implications for social and clinical judgments and behaviour.”

What Is Non 24 Sleep Wake Disorder

Those with non-24-hour sleep-wake syndrome do not have internal clocks that reset and stay balanced within a 24 hour schedule. In most cases, their circadian rhythms are set on longer loops, usually resulting in 25 or 26 hour cycles, or even more in some cases. There have documented cases of people having as dramatic as 72 hour cycles, in which they would stay awake for 48 straight hours, and then for 24 straight hours as a regular . There are only a few known dramatic cases such as that though, and most cases fall within the 25 or 26 hour range.

What this means for these individuals is that their sleep and wake times are pushed back by 1 or 2 hours every day. This leads to a constant cycle between sleep times that are considered unconventional by society’s standards, with occasional short stops in conventional time frames before progressing on again into unconventional. This extremely unbalanced sleeping schedule makes it all but impossible for the subject to hold a traditional job, or attend regularly scheduled school classes unless they fight the disorder, which is not easy without the proper treatment. individuals living with this have often found their ‘calling’ working in a self employed capacity, or in a number of other fields of work where they can effectively set their own work schedule. Those still attending school may find it necessary to take home schooling through the internet or other avenues.

Is 9 Hours Of Sleep Better Than 8

How Much Sleep Is Too Much? Sleep needs can vary from person to person, but in general, experts recommend that healthy adults get an average of 7 to 9 hours per night of shuteye. If you regularly need more than 8 or 9 hours of sleep per night to feel rested, it might be a sign of an underlying problem, Polotsky says.

Can You Survive A Day With 3 Hours Of Sleep

At this point, you may be wondering if 3 hours of rest is for you and could be wondering how to function after so little time. Exercise and energy-boosting foods could be helpful, healthy ways to help you adjust to this new sleep cycle. Ultimately, your body will tell you whether or not you can manage 3 hours sleep a day.

Downsides Of Skipping Sleep Altogether

IGNITE Spotlight: Sleep Lounge

Sleepiness is regulated by two processes: your circadian rhythm and sleep pressure.

Your circadian rhythm is your body’s internal clock that makes you feel tired at night and awake during the day. Sleep pressure is a feeling of tiredness that gets stronger the longer you stay awake. If you don’t sleep, your drowsiness will continue to get worse until you can finally get some rest.

Sleeping for 1 to 2 hours can decrease sleep pressure and make you feel less tired in the morning than you otherwise would by staying up all night.

If you don’t get enough sleep, you’ll likely experience:

Is 6 Hours Of Sleep Enough

Unless you’re within the ultra-rare category of people who need less sleep, then no, 6 hours of sleep a day is not enough. 6 hours might be enough to make you feel ‘normal’, but based on countless scientific studies – 6 hours isn’t giving your mind and body enough time to keep you the healthiest and happiest you can be. Missing out on 2 hours a night might not sound a lot, but it definitely adds up.

What Are The Symptoms Of Sleep Deprivation

The primary signs and symptoms of sleep deprivation include excessive daytime sleepiness and daytime impairment such as reduced concentration, slower thinking, and mood changes.

Feeling extremely tired during the day is one of the hallmark signs of sleep deprivation. People with excessive daytime sleepiness may feel drowsy and have a hard time staying awake even when they need to. In some cases, this results in in which a person dozes off for a matter of seconds.

Insufficient sleep can directly affect how a person feels during their waking hours. Examples of these symptoms include:

  • Slowed thinking
  • Lack of energy
  • Mood changes including feelings of stress, anxiety, or irritability

A person’s symptoms can depend on the extent of their sleep deprivation and whether it is acute or chronic. Research also suggests that some individuals are more likely to experience symptoms after a lack of sleep and that this may be tied to a person’s genetics. Stimulants like caffeine can also mask the symptoms of sleep deprivation, so it’s important to note how you feel on and off these substances.

Are There Negative Effects

Some experts do caution against these types of methods because there is very little research to show what the long-term ramifications may be. Some worry that shifting the sleep cycles is unnatural and could be a detriment to the metabolic and endocrine systems. A spike in blood sugar levels and hormone disruptions may also be caused by reduced sleeping methods.

How Much Sleep Do People Really Need

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.

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.”

Avoid Things That Can Interfere With Sleep

A useful step in addressing sleep deprivation is to avoid things that can, often unbeknownst to you, negatively affect your sleep:

  • Electronic devices: TVs, cell phones, tablets, and computers can keep your mind stimulated, leaving you still wired when you want to go to bed. The light emitted by these devices can also interfere with your circadian rhythm. As a result, it’s best to avoid using electronic devices for an hour or more before bed.
  • Alcohol: Drinking, especially at night, can disrupt your normal sleep cycle, reducing overall sleep quality and consistency.
  • Caffeine: As a stimulant, caffeine makes you alert, and because it can stick around in your system for several hours, it’s best to avoid it in the afternoon and evening.
  • Naps: To keep naps from interfering with sleep at night, keep them short and never take them in the late afternoon or later. If you are struggling with insomnia, it’s best to avoid naps altogether.

No Driving Policy When Tired

While fans of the Everyman method do report an increase of energy, they have also been known to experience deeper feelings of exhaustion just before nap times. These sleepers may become so tired that they are slightly delirious and have trouble handling ordinary tasks before taking their 20-minute nap.

For this reason, it is very important that you do not operate a motor vehicle when you are feeling less than fully awake. Adhere to a strict policy that forbids you from driving when you are likely to experience these exhausted states to ensure your personal safety and the safety of others.

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 you’re 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. You’ll 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

Plan A Schedule That Works

Bedtime Books We Love, Love, Love

No two reduced sleep schedules will look the same. You will need to find ways to plan your nap times around your work and social schedules. Don’t feel too pressured to stick to a specific schedule if it cannot realistically fit into your day.

Some people have had success requesting a little down time around their lunch hours at work. Others prefer to have their “core” sleep earlier or later in the night depending on their general habits. Many longtime sleepers that do this caution that it may take a few weeks to fully adjust, so keep that in mind when determining whether or not your schedule needs to be revised.

Differences In 6 Vs 8 Hours Of Sleep

Not surprisingly, test subjects who slept the recommended eight hours a night had the highest performance ratings. Those who slept six hours a night did fine until nearing the end of the study, around day 10, and those functioning on just four hours of sleep were noticeably worse each day.

The study found that the test subjects that slept four or six hours per night had a significant decrease in cognitive performance, functioning the same as if they had been deprived of sleep for two days. The difference between the four- and six-hour groups was that the performance of the four-hour group declined more quickly.

Even more interestingly, the test subjects that showed decreased cognitive performance after 10 days of sleeping six hours per night were seemingly unaware of the changes, based on their “sleepiness ratings” given.

Is 6 Hours Of Sleep Enough 10 Answers Backed By Science

‘I get by just fine on 6 hours sleep a night’

…is one of the biggest lies told by people today.

We see it everywhere. From ambitious friends to business leaders – just about everyone seems to think they don’t need a full night’s rest.

Supposedly, President Trump gets by on just 4-5 hours, while famed entrepreneur Elon Musk spends ‘120 hours’ a week working – tweeting at 2.32am that ‘sleep is not an option’.

Maybe all of these people are blessed with not needing sleep. Granted, it’s true that some lucky people don’t feel as much of the effects of not sleeping. However, that number is 1 in 12,000 people who only need 6 hours.

That is less than 0.01% of the population who don’t need 8 hours of sleep every night. 

If you think about all of the people you’ve ever met in your life, maybe one of them is in this category. It is super rare.

So why do so many people believe they have this super power? I don’t know about you, but at least 1 in 5 people I know are convinced they’re ‘doing just fine’ on 6 hours sleep.

This might be because of developing a new baseline. In other words – ‘you do not know how sleep-deprived you are when you are sleep deprived’. As the renowned sleep scientist Matthew Walker writes in his book

With chronic sleep restriction over months or years, an individual will actually acclimate to their impaired performance, lower alertness, and reduced energy levels. That low-level exhaustion becomes their accepted norm, or baseline.

What Happens When We Only Get 6 Hours Of Sleep

Below I’ve collated a list of things that happen when we don’t sleep. It doesn’t make for fun reading, but it’s important to know what we’re missing out on when we’re pushing ourselves to burn the candle at both ends. And given what sleep scientists have found, you may not even recognize that you’re suffering from these right now!

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.

So Why Is 6 Hours Of Sleep Per Night Detrimental

The group that was allowed to sleep for eight hours a night as you can imagine performed the best with the cognitive and reaction tests. Those who were sleeping for just four hours a night got worse as the days went on.

Interestingly the group who had 6 hours of sleep were doing fine until around day ten.

What is even more interesting is that by day ten, the six-hour sleepers were showing test results that were worse than the group who had not been allowed to sleep. As expected the four-hour sleepers performed badly but they hit their low a lot sooner than the six-hour sleepers.

The problem with these results is that the six-hour sleepers worryingly felt fine. They didn’t feel particularly sleepy and they didn’t realize how badly they were performing in the testing. Those who had no sleep noted their sleepiness increase as the days went on, as we would have expected.

The group that had only 6 hours of sleep didn’t notice a significant increase in their sleepiness. This poses the question: if we only get 6 hours of sleep per night over a long period, are we in denial of our sleepiness?

Keeping A Sleep Schedule Is Easy During The Week Not So Much On The Weekend

On Friday night, I realized getting nine hours of sleep was a distant possibility. My fiancé returned home from a week-long work trip, so a reunion Netflix session kept me up past my assigned bedtime. To make matters worse, I had to get up at 4:00 a.m. the following day for a race. That meant I had to be in bed by 7:00 p.m. on a Friday night if I wanted nine hours of sleep. I cared about the sleep experiment and everything, but there was no way I could conk out that early.

In fact, I didn’t sleep at all Friday night, which is typical when I have an early morning race. But the sleep I’d gotten the rest of the week seemed to carry me through the day. I was able to meet up with my friends, complete the race , and join a bunch of people for celebratory brunch. Similar mornings have left me delirious from sleep deprivation, but instead I felt like socializing and having fun. Then I arrived back home, announced I would stay awake the rest of the afternoon, and promptly took a three-hour nap.

Is It Better To Sleep For An Hour Or Not At All

We all need at least 7 hours of sleep to be at our best. But sometimes life gets in the way. You were up late cramming for an exam, preparing for an important work presentation, or simply too busy having fun with friends.

Whatever your reason, you now find yourself faced with the potential of an all-nighter. Is it better for you to sleep for an hour, or not at all?

The funny thing is: it’s a trick question. If you’re forced to choose between staying up all night or sleeping for an hour, the better option is to have just a 20 to 30 minute nap instead.

Surprised? We thought you might be. It can all be explained by your sleep cycle.

How Do We Get A Good Nights Sleep

Get your head down on World Sleep Day!

The best way to try and get a good night’s sleep is to try and have a consistent bedtime. It’s also important to put down your tablet and smartphone, at least 30 minutes before you plan on going to bed. You should limit your alcohol consumption as well as trying to undertake regular exercise.

If you try and do these four things it should help get you to sleep and ensuring you remain asleep. If your brain is working as if it’s been awake for 48 hours, it’s worth giving these tips a try.

Sleep Experts Close In On The Optimal Night’s Sleep

How much sleep do you really need?

Experts generally recommend seven to nine hours a night for healthy adults. Sleep scientists say new guidelines are needed to take into account an abundance of recent research in the field and to reflect that Americans are on average sleeping less than they did in the past.

Several sleep studies have found that seven hours is the optimal amount of sleep—not eight, as was long believed—when it comes to certain cognitive and health markers, although many doctors question that conclusion.

Other recent research has shown that skimping on a full night’s sleep, even by 20 minutes, impairs performance and memory the next day. And getting too much sleep—not just too little of it—is associated with health problems including diabetes, obesity and cardiovascular disease and with higher rates of death, studies show.

“The lowest mortality and morbidity is with seven hours,” said Shawn Youngstedt, a professor in the College of Nursing and Health Innovation at Arizona State University Phoenix. “Eight hours or more has consistently been shown to be hazardous,” says Dr. Youngstedt, who researches the effects of oversleeping.

Is 75 Hours Of Sleep Better Than 8

These groups currently recommend seven to nine hours of nightly sleep for healthy adults. The National Heart, Lung and Blood Institute recommends seven to eight hours, including the elderly. Most current guidelines say school-age children should get at least 10 hours of sleep a night, and teenagers, nine to 10.

How Low Can You Go

Most likely, everyone has driven a car while feeling sleepy on at least one occasion. But how much sleep do you truly need before it is definitely unsafe to drive? Recently, the National Sleep Foundation, in consultation with experts from the field of sleep medicine and the transportation industry, convened a panel to answer this question. It’s a complex one because there are several other factors besides sleep duration that determine one’s level of sleepiness. For example, a large amount of pre-existing “sleep debt” will magnify the impact of acute sleep deficiency. In addition, the time of day makes a difference. At night, your natural body clock is set for “sleep,” and therefore the reduction in alertness from acute sleep loss will be worse than during the day. This is why drowsy driving accidents occur mostly at night. And of course, the quality of one’s sleep is critical — which is why, for example, trying to pay back your sleep debt with a motel room next to railroad tracks is ill-advised!

After considering all these issues and the available evidence, the panel concluded that a driver is definitely impaired if he or she has had less than two hours of sleep in the preceding 24 hours.

How The Sleep Cycle Works

Your body cycles through four stages of sleep throughout the night. One cycle takes about 90 minutes.

During a typical night’s sleep, you’ll cycle through each stage four to six times. If you’re limiting yourself to 4 hours of sleep, you’ll only have time to cycle through these stages twice.

The sleep stages are:

  • N1. This is the lightest stage of sleep, lasting 1 to 5 minutes. During this stage, your breathing and heart rate slow down and your muscles relax.
  • N2. This stage lasts about 30 to 60 minutes. Your breathing and heart rate slow down even further and your body temperature drops.
  • N3. The third stage of sleep is also known as deep sleep. This period, which lasts about 20 to 40 minutes, is when your body repairs damaged tissues and cells.
  • Rapid eye movement . REM is the stage most associated with dreaming. Your first REM cycle lasts about 10 minutes and your last one can last up to 1 hour.

Make Sleep A Priority

Chronic insufficient sleep often occurs when people choose to sacrifice sleep in favor of work, leisure, or other obligations. To counteract this, it’s critical to take steps to make sleep a priority:

  • Have a consistent sleep schedule: You should strive to go to bed and wake up at the same times every day. In planning those times, make sure to budget time to get enough sleep. Once you’ve settled on your schedule, follow it closely, even on weekends. Stability in your sleep routine helps avoid fluctuations in your nightly sleep.
  • Set boundaries in your work and social life: It’s easy for the demands of your personal or professional life to chip away at your dedicated time for sleep, so it’s helpful to set boundaries so that you preserve the full time you need for rest each night.
  • Have a bedtime routine: Get yourself ready each night with the same steps such as quietly reading or stretching, putting on pajamas, and brushing your teeth. A steady bedtime routine can put you in the right frame of mind to sleep well each night.

Customize Your Bedroom Environment

environment to be ideal for your relaxation. You’re less likely to avoid going to bed if your sleep setting is inviting and suits your comfort preferences.

Your and pillows should offer plenty of support, and your bedding should help you feel cozy while maintaining a moderate temperature. To minimize potential sleep disruptions, try to make sure your bedroom is as quiet and dark as possible.

How Much Sleep Do You Get Per Night

We find it very difficult to know how much sleep we get per night. A study based on American statistics that 35% of Americans sleep under seven hours per night.

A different showed that we tend to overestimate how much we sleep. So those Americans who felt they slept seven hours, might have in fact been sleeping for only six hours.

Thatcher: Can People Get By On Four Hours’ Sleep

5 Steps For Your Perfect Sunday

Margaret Thatcher is famously said to have slept for only four hours a night. How easy is it to do a high-powered job on this amount of sleep?

Part of Margaret Thatcher’s fearsome reputation came from how little she slept. She could get by on four hours a night, it has often been said.

Indefatigability became part of her mystique. She would keep her officials up working on a speech until two or three in the morning and then be up by five in time to listen to Farming Today.

“She slept four hours a night on weekdays,” says Sir Bernard Ingham, her Downing Street press secretary. “I wasn’t with her at weekends. I guess she got a bit more then.”

It isn’t easy to ascertain when Baroness Thatcher first referred to her minimal sleep schedule, but the figure of four hours has passed into lore.

People use it as a benchmark of endurance, often jokingly referring to those who need much more.

Lady Thatcher’s close friend and former Conservative Party treasurer Lord McAlpine stayed with her at Chequers during the holidays. “She worked right through Christmas. When everyone else went off to bed she went off to work.”

Her biographer John Campbell, author of The Iron Lady, says her late-to-bed, early-to-rise routine made her the “best informed person in the room”. Occasionally husband Denis would snap. “Woman – bed!” he is reputed to have shouted on one occasion.

But is the four-hour measure something ordinary people should aspire to?

He makes a worse advert than Lady Thatcher did.
