Sleep Deprivation And Sleep Debt

The amount of sleep a person needs goes up if they’ve missed sleep in previous days. If you don’t have enough, you’ll have a “sleep debt,” which is much like being overdrawn at a bank. Eventually, your body will demand that you start to repay the debt.

We don’t really adapt to getting less sleep than we need. We may get used to a schedule that keeps us from getting enough sleep, but our judgment, reaction time, and other functions will still be off.

Myth: More Sleep Is Always Better

While most concerns about sleep duration focus on sleeping too little, there are also problems that can arise from sleeping too much.

People in specific circumstances, such as recovery from illness, may need extra sleep, but excessive sleep, in general, can be a symptom of an underlying health problem. In addition, studies have found higher rates of mortality in people who sleep too much, but more research is needed to better understand this association.

Myth: Exercising At Night Disturbs Sleep

Percentage of participants that signed the statement ...

Data from surveys and research studies indicates that even vigorous exercise at night does not usually affect sleep. In fact, working out at night helps many people sleep better.

That said, for some people, it may not be beneficial to do extremely intense workouts immediately before going to bed as this may make it hard for your body to relax and settle into sleep.

Repair And Restoration Theory

According to the repair and restoration theory of sleep, is essential for revitalizing and restoring the physiological processes that keep the body and mind healthy and properly functioning.??

This theory suggests that NREM sleep is important for restoring physiological functions, while REM sleep is essential in restoring mental functions.

Support for this theory is provided by 2011 research that shows periods of REM sleep increase following periods of sleep deprivation and strenuous physical activity.?? During sleep, the body also increases its rate of cell division and protein synthesis, further suggesting that repair and restoration occur during sleeping periods.

Dreams and the REM Stage of Sleep

In 2013 researchers have uncovered new evidence supporting the repair and restoration theory, discovering that sleep allows the brain to perform “housekeeping” duties.??

In the October 2013 issue of the journal Science, researchers published the results of a study indicating that the brain utilizes sleep to flush out waste toxins. This waste removal system, they suggest, is one of the major reasons why we sleep. It’s important to realize, however, this study was done on mice and not humans.??

“The restorative function of sleep may be a consequence of the enhanced removal of potentially neurotoxic waste products that accumulate in the awake central nervous system,” the study’s authors explained.??

What Impact Does Sleep Have on Mental Health?

How Are Memory And Sleep Connected

Sleep and memory share a complex relationship. Getting enough rest helps you process new information once you wake up, and sleeping after learning can consolidate this information into memories, allowing you to store them in your brain.

Some studies have found sleep quality decreases with age. This is tied to slow-wave sleep. Slow waves are produced in an area of the brain known as the medial prefrontal cortex. The medial prefrontal cortex will deteriorate over time, and as a result, older people typically experience less slow-wave sleep during a normal sleep cycle and have a harder time processing memories.

Sleep Deprivation May Create False Memories

A new study published recently in Psychological Science suggests that not getting enough sleep may increase the likelihood of forming false memories.

The study was conducted by psychological scientist Steven J. Frenda of the University of California, Irvine and colleagues. Results show sleep-deprived people who viewed photos of a crime being committed and then read false information about the photos were more likely to report remembering the false details in the photos than were those who got a full night’s sleep.

“Over the years I noticed that whenever I had a bad night’s sleep, my perception and memory seemed to get fuzzy until I had a good recovery sleep,” explains Frenda. “I was surprised to find that there were so few empirical studies connecting sleep deprivation with memory distortion in an eyewitness context. The studies that do exist look mostly at sleep deprived people’s ability to accurately remember lists of words — not real people, places and events.”

A preliminary study conducted by Frenda and colleagues suggested that getting five hours of sleep or less was linked to the formation of false memories. The researchers then designed an experiment to examine whether staying up all night would increase the probability of forming false memories.

In the second part of the experiment, participants read narratives containing statements that differed from what the photos actually showed.

Circadian Rhythms The 24

refer, collectively, to the daily rhythms in physiology and behavior. They control the sleep-wake cycle, modulate physical activity and food consumption, and over the course of the day regulate body temperature, heart rate, muscle tone, and hormone secretion. The rhythms are generated by neural structures in the hypothalamus that function as a biological clock . Animals and plants possess endogenous clocks to organize daily behavioral and physiological rhythms in accord with the external day-night cycle . The basis for these clocks is believed to be a series of molecular pathways involving “clock” genes that are expressed in a nearly 24-hour rhythm .

In mammals, two proteins, Clock and Bmal1, bind together and move into the nucleus of the cell, where they bind to specific sites in the DNA that activate specific genes . Among the genes that they activate are Period and Cryptochrome. The products of these genes also move back into the nucleus, where they disrupt the binding of Clock and Bmal1 to the DNA, thus inhibiting their own synthesis. This results in a rising and falling pattern of expression of the Period and Cryptochrome gene products with a periodicity that is very close to 24 hours.

Molecular mechanisms underlying the activity of the circadian clock. NOTE: The activation and deactivation of Period and Cryptochrome protein production is the basis of a negative-feedback loop that controls the ~24-hour cycle time of circadian clocks.

Myth: The Ability To Fall Asleep Anywhere And At Any Time Means Youre A Good Sleeper

Being able to fall asleep at any time and under any circumstances is a sign of having sleep problems, not of being a “good sleeper.”

This myth is dangerous because it puts a positive spin on excessive daytime sleepiness, which is usually a symptom of , insufficient sleep, or an underlying sleep disorder like sleep apnea. Sleeping at any time can also be tied to circadian rhythm disorders and .

As a sleeper, your goal shouldn’t be the ability to fall asleep in any situation. Instead, it should be to strive for a proper amount of high-quality sleep that occurs on a regular schedule that, whenever possible, involves sleeping at night in order to reinforce a healthy circadian rhythm.

What Affects Sleep Quality

Chemical signals in the brain influence our sleep and wake cycles. Anything that shifts the balance of these neurotransmitters can make us feel drowsier or more awake. For example:

  • Alcohol may help people fall into a light sleep. But it reduces the deeper stages of sleep and REM sleep and leads to more disrupted sleep.
  • Caffeine and pseudoephedrine can stimulate the brain. They may cause , an inability to sleep. Watch out for caffeinated drinks such as coffee and drugs such as diet pills and decongestants.
  • Medications such as can cause less REM sleep.
  • People who smoke heavily often sleep lightly and have less REM sleep. They may wake up after a few hours because they experience nicotine withdrawal.
  • Very hot or cold temperatures can disrupt REM sleep. We’re less able to regulate body temperature during REM sleep.

Rem Sleep Behavior Disorder

PPT

Some people are affected by REM sleep behavior disorder , a condition where the muscle paralysis normally experienced during REM sleep does not occur. This causes the person to act out vivid dreams. For example, they may kick, yell, or flail their arms about.

Onset of REM sleep behavior disorder tends to be gradual, with symptoms worsening over time.

RBD is caused by malfunctioning nerve pathways in the brain. Risk factors for its development include:

  • Being male.
  • Taking certain medications, including some types of .
  • Withdrawal from drugs or alcohol.
  • Having a neurodegenerative disorder, such as Parkinson’s disease or Lewy body .
  • Having , a sleep disorder characterized by excessive daytime sleepiness and hallucinations.

Treatment for REM sleep behavior disorder includes medication and making changes to the sleep environment to increase safety for the person with the condition and their sleeping partner.

There are several ways to enhance both REM and NREM sleep to reap the benefits of a good night’s sleep. The following tips may help improve REM sleep:

What Is Rem Sleep

When you enter REM sleep, brain activity increases again, meaning sleep is not as deep. The activity levels are like when you’re awake. That’s why REM sleep is the stage where you’ll have intense dreams.

At the same time, major muscles that you normally control can’t move. In effect, they become temporarily paralyzed.

Usually, REM sleep arrives about an hour and a half after you go to sleep. The first REM period lasts about 10 minutes. Each REM stage that follows gets longer and longer.

The amount of REM sleep you experience changes as you age. The percentage of REM sleep:

  • Is highest during infancy and early childhood.
  • Declines during adolescence and young adulthood.
  • Declines even more as you get older.

      Consequences Of A Lack Of Rem Sleep

      A lack of REM sleep has been linked to:

      Reduced coping skills – indicates that animals who are deprived of REM sleep show abnormalities in coping mechanisms and defensive responses in threatening situations.

      Migraines – not getting enough REM sleep has been linked to.

      Overweight – a University of Pittsburgh found that short sleep times and reduced REM sleep was associated with excess weight in children and adolescents.

      Alcohol can impact REM sleep.

      While drinking alcohol may help some people fall asleep quicker, research suggests that it reduces REM sleep.

      The more alcohol consumed before sleep, the more REM sleep is impacted.

      A 2013 review of 27 studies on alcohol and sleep found that total nightly REM sleep was decreased at moderate and high intakes of alcohol, although no clear trend was seen at low levels of alcohol intake.

      The onset of the first REM sleep period – which usually occurs 90 minutes after falling asleep – was “significantly delayed at all doses.”

      Alcohol affects sleep in other ways, too. It contributes to sleep apnea and snoring, causes an increase in bathroom visits, and interrupts the body’s circadian rhythm – the internal clock that regulates sleep and wake times.

      Myth: Your Brain Shuts Down During Sleep

      The brain remains active during sleep. Its patterns of activity change during different sleep stages, and in rapid eye movement sleep, brain activity ramps up to a level that shares similarities with when you’re awake.

      Far from shutting down, shifts in brain activity during sleep are believed to be part of why sleep is critical to effective thinking, memory, and emotional processing.

      Confidence Ratings And Remember/know/guess Judgments In Recognition Memory

      All subjects tested in Experiments I to IV gave confidence ratings for their answers in the recognition memory test, as well as remember/know/guess judgments for the positive answers , . Confidence ratings were in all experiments distinctly higher for theme words and list words when compared to distractors . Also the proportion of “remember” judgments was higher for theme words and list words than for distractors in all experiments . However, in none of the experiments differed the groups significantly in these variables , indicating that sleep deprived subjects did not exhibit higher confidence or more remember judgments on false memories, hits or false alarms compared to non-deprived controls.

      Myth: Alcohol Before Bed Improve Sleep

      A drink or two can be relaxing, inducing drowsiness that makes it easier to initially fall asleep. The problem is that the quality of sleep declines considerably after drinking alcohol. Consuming alcohol before going to bed can throw off your sleep cycles, make it more likely your sleep will be interrupted, and worsen snoring and sleep apnea.

      Because of its negative effects on sleep, reducing or eliminating alcohol consumption before bed is frequently recognized as an important part of sleep hygiene.

      Are You At Risk For Falling Asleep Behind The Wheel

    • The largest at-risk group for sleep-related crashes is commercial drivers.
    • Overall, sleep-related crashes have certain characteristics that set them apart from other types of crashes.
    • People with a sleep and breathing disorder called obstructive sleep apnea have about the same risk as the rest of the general population of being involved in a drowsy-driving crash.
    • Eating a big lunch tends to make everyone sleep.
    • People can usually tell when they are going to fall asleep.

    • What Is Sleep Deprivation

      Solved: Studies The Basic Challenge Of Understanding The B ...

      When you’re sleep deprived, you’re not getting the total amount of sleep you need. Signs of sleep deprivation include:

      • Falling asleep within a few minutes of lying down.
      • Feeling drowsy during the day.
      • Nodding off for microsleeps — short periods of sleep during the day when you’re otherwise awake.
      • Sleep deprivation can be dangerous. Driving while tired causes about 100,000 car accidents each year, according to the National Highway Traffic Safety Administration. It also causes 1,500 deaths. If you feel tired on the road, pull over. It’s not safe to drive if you’re drowsy.

      Sleep Apnea And Memory Loss

      Since sleep is so crucial to the formation and consolidation of memories, some sleep disorders are associated with memory problems. , defined as persistent difficulty initiating or maintaining sleep, is known to cause daytime cognitive impairments including reduced memory functioning. Sleep disorders that lead to such as can cause memory lapses.

      One disorder, sleep apnea, may actually promote memory loss. Sleep apnea is characterized by the temporary cessation of the airway during sleep that can cause people to choke or gasp for air. Heavy snoring and excessive daytime sleepiness are other common symptoms of sleep apnea.

      More than 900 million people across the globe live with obstructive sleep apnea , a subtype of the disorder that occurs when a physical blockage impedes the airway. OSA has long been linked to chronic depression. People with depression often have a difficult time processing memories, specifically autobiographical memories that pertain to their own experiences. People with OSA have also demonstrated difficulty with memory consolidation.

      These results suggest sleep apnea can interfere with the memory consolidation process, causing people to have a hard time recalling certain memories of their own life. However, more research is needed to explore whether OSA leads to both depression and memory problems, or if OSA and depression independently affect memory consolidation.

      Myth: If You Cant Sleep Its Best To Stay In Bed Until You Fall Back Asleep

      Sleep experts recommend getting out of bed if you can’t fall asleep within 20 minutes. Instead of tossing and turning in bed, it’s better to get up, do something relaxing in a quiet and dim setting , and then try to go back to bed.

      The reason experts advise this approach is that it’s important to associate your bed with sleep. Staying in bed while struggling to sleep can do the exact opposite, linking your bed with a feeling of frustration.

      How Many Hours Of Sleep Do You Need

      The amount of a person needs depends on many things, including their age. In general:

      • Infants need 14-17 hours a day.
      • Infants need 12-15 hours a day
      • need about 11-14 hours a day.
      • Preschool children need 10-13 hours a day.
      • School-age children need 9-11 hours a day.
      • Teenagers need about 8-10 hours each day.
      • Most adults need 7 to 9 hours, although some people may need as few as 6 hours or as many as 10 hours of each day.
      • Older adults need 7-8 hours of sleep each day.
      • Women in the first 3 months of pregnancy often need several more hours of sleep than usual.

      But experts say that if you feel drowsy during the day, even during boring activities, you haven’t had enough sleep.

      Myth: Turning Up The Radio Opening The Window Or Turning On The Air Conditioner Are Effective Ways To Stay Awake When Driving

      Drowsy driving is extremely dangerous, and these “tricks” are ineffective and are especially worrisome if they keep a sleepy driver behind the wheel.

      If you’re feeling tired while driving, the best and safest thing to do is pull off the road and into a safe area where you can nap for 15-30 minutes or simply stop for the night. Caffeinated drinks may help for a short period, but it can take time for caffeine to kick in. Even then, it’s risky to rely on caffeine to keep you alert when driving.

      The best way to deal with drowsy driving is to prevent it in the first place by getting a good night’s sleep before your trip. When in doubt, err against driving if you’re at all sleepy because the consequences can be life-threatening to you and others on the road.

      What Are Good Sleep Habits

      Good sleep habits, also called good sleep hygiene, are practices to help you get enough quality sleep.

      Do:

      • Have a sleep schedule: Go to sleep and wake up around the same time every day, even on weekends and vacations.
      • Clear your mind before bed: Make a to-do list early in the evening, so you won’t stay awake in bed and worry about the next day.
      • Create a good sleep environment: Make sure your bed and pillows are comfortable. Turn down the lights and avoid loud sounds. Keep the room at a comfortable temperature.
      • Exercise every day: Stay active but try to avoid exercising during the few hours right before bed.
      • Relax: Before bed, take a warm bath, read or do another relaxing activity.
      • See your healthcare provider: If you’ve been having trouble sleeping or feel extra drowsy during the day, talk to your provider. There are many treatments available for sleep disorders.

      Don’t:

      A note from Cleveland Clinic

      Far from being a state of doing nothing, sleep is an essential part of our lives. It helps our body rest, recharge and repair. There are four sleep stages — three in the non-REM phase plus REM sleep. Many factors can affect sleep quality, including the food and drink you consume before bed and room temperature. Many people experience trouble sleeping now and then. But if you think you may have a sleep disorder, talk to your healthcare provider. Common sleep disorders include insomnia and sleep apnea . Your provider can help you get the diagnosis and treatment you need.
